STEMMING THE TIDE OF MISINFORMATION:
INTERNATIONAL CONSENSUS ON SHARED PARENTING
AND OVERNIGHTING
Richard A. Warshak, Ph.D.
*
ABSTRACT
Warshak, with the review and endorsement of 110 researchers and
practitioners, analyzed more than four decades of research and issued
a peer-reviewed consensus report on parenting plans for young
children. As intended, the report stemmed a tide of misinformation that
was threatening to resurrect myths about child development and
enshrine them in professional practice and family law. The list of
endorsers and their professional accomplishments reflect the
widespread acceptance of the consensus report’s findings that favor
shared parenting and overnighting for young children under normal
circumstances. Two years after its publication, the conclusions and
recommendations of the Warshak consensus report remain supported
by science.

INTRODUCTION
Main Issues
Judges and lawmakers hear competing versions from the mental health field
about what type of parenting plans are best for very young children. Discussions
of parenting time for young children who are raised by parents who live apart
from each other generally address three main issues.
1. Should young children’s time be concentrated predominantly under the
care and supervision of one parent, or should their time be more evenly
divided between parents?
2. Should young children under the age of four spend nights in each parent’s
home, or should they sleep in the same home every night?
3. Are the benefits to the child of involvement with both parents, or
overnight care, diminished or erased if the parents disagree about the
parenting plan, or if one or both parents feel great discomfort or hostility
toward the other?
Differences of opinion regarding shared parenting time for children under the
age of four years focus on the issue of whether giving children more time with
their fathers, aimed at strengthening father-child relationships, risks harming
mother-child relationships. The concern is that spending too much time away
from the mother, or having overnights away from her, rather than increasing the
odds that a child will have a high quality relationship with both parents, will result
in the child having poor relationships with both parents.
Background
Our society holds a curious double standard when it comes to encouraging
hands-on shared parenting. For instance, we want dads involved with their infants
and toddlers—diapering, feeding, bathing, putting to bed, soothing in the middle
of the night, cuddling in the morning. But when parents separate, some people
think that young children need to spend every night in one home, usually with
mom, even when this means losing the care their dad has been giving them.
Despite all strides in cracking gender barriers, many of us still think that it is
primarily the mother’s role to care for infants and toddlers, and that we jeopardize
young children’s wellbeing if we trust fathers to do the job.
Where does science stand on these issues? A body of research from the 1970s
to the 1990s challenged stereotypes and prejudices that had governed child
custody decisions throughout most of the 19
th
and 20
th
centuries. The results of
social science studies throughout the United States converged to support the

position that most children needed and wanted more contact with their fathers
after divorce than they were having.
1
In 1994 a multidisciplinary group of experts, sponsored by the U.S. National
Institute of Child Health and Human Development (NICHHD), met to evaluate
the empirical evidence regarding the ways in which children are affected by
divorce and the impact of various custody arrangements. In 1997, eighteen
experts from the NICHHD group issued a consensus statement concluding:
Time distribution arrangements that ensure the involvement of
both parents in important aspects of their children’s everyday lives
and routines—including bedtime and waking rituals, transitions to
and from school, extracurricular and recreational activities—are
likely to keep nonresidential parents playing psychologically
important and central roles in the lives of their children. How this
is accomplished must be flexibly tailored to the developmental
needs, temperament, and changing individual circumstances of the
children concerned.
2
Over time, custody policy and decisions increasingly reflected the importance
of frequent and continuing contact between children and both parents, including
giving children more contact with their fathers. Nevertheless, professional
opinions continued to favor the practice of denying infants and toddlers overnight
contact with their fathers, even those children who had been accustomed to seeing
their dads every day and experiencing his care at bedtime, in the middle of the

night, and in the morning.

I labeled presumptions against “overnighting” until
children reach the age of four or five,
blanket restrictions.
Between 2000 and 2002 a well-cited exchange of articles in
Family Court
Review
addressed the wisdom of guidelines that restricted young children from
sleeping in their fathers’ home. One group of authors supported flexible,
individualized parenting plans rather than absolute rules favoring or prohibiting
overnights.
4
Those authors recommended that decision makers consider the option
of overnights with fathers for its potential benefits to the children’s developing
stable and lifelong relationships with both parents. Those opposing this view
conceded the need for some relaxation of blanket restrictions, but continued to
emphasize the potential harm rather than potential benefits of overnights.
5
They
proposed that overnights should be viewed with caution rather than prohibited or
contraindicated on an a priori basis, thus accepting that in some cases overnights
with their fathers might be in young children’s best interests.
In the aftermath of the 1997 consensus statement, subsequent articles on
parenting plans for young children, and a growing body of research relevant to
parenting plans, the importance of providing sufficient opportunities for children
to develop and maintain high quality relationships with both parents became
generally recognized as the accepted and settled science with respect to child
custody issues.
6
The decade between 2001 and 2011 saw increasing acceptance of
overnights for infants and toddlers among mental health professionals, courts, and
parents. This remained the zeitgeist until 2011.

Controversy over the previous decade’s accepted science with respect to
overnights for young children reignited in 2011 when the Association for Family
and Conciliation Courts (AFCC) gave a unique platform to Jennifer McIntosh via
an invitation to guest edit a special issue of the
Family Court Review
(FCR) in
which McIntosh listed herself as author of nine articles (eight of which were
edited transcripts of interviews that McIntosh conducted with commentators).
AFCC then invited McIntosh to deliver a plenary address at its annual conference
in 2012.
7
McIntosh advocated that one parent should be designated the primary
caregiver, discouraged joint physical custody for children under the age of four,
and called for the resurrection of blanket restrictions unless overnights were
necessary and helped the primary caregiver.
8
Subsequent articles criticized
AFCC, FCR, and McIntosh for presenting a narrow perspective.

CURRENT CONSENSUS OF SOCIAL SCIENTISTS ON
PARENTING PLANS FOR YOUNG CHILDREN
Practitioners and scholars in the field of child custody expressed concerns that
this seeming reversal of a decade-long endorsement of shared parenting for
preschool children was generating widespread confusion and uncertainty about
where the scientific community stood on these issues. To give voice to those
concerns, and in an effort to right a ship that was listing from a tide of
misinformation, I spent two years reviewing the relevant scientific literature. Then
I vetted my analyses by incorporating feedback from an international group of
experts in the fields of attachment, early child development, parent-child
relations, and divorce. The results appeared in
Social Science and Parenting
Plans for Young Children: A Consensus Report
published in the American
Psychological Association’s journal,
Psychology, Public Policy, and Law,
that is
edited by Cambridge University Professor Michael Lamb, a prominent child
development scholar.
11
The report was published with the endorsement of 110 of
the world’s leading researchers and practitioners, several who contributed seminal
studies cited in the report.
The first goal was to provide a balanced and accurate overview of settled,
accepted research from the past 45 years relevant to parenting plans for children
under the age of four whose parents lived apart. The second goal was to provide
empirically informed guidelines for policy makers and for people involved in
making custody decisions.
No support was found for the idea that children under four need or benefit
from restrictions with parents who are loving and attentive. Warnings against
infants and toddlers spending overnight time with each parent are inconsistent
with what we know about the development of meaningful, positive parent-child
relationships in the first few years of children’s lives. Babies and toddlers need
journal issue solely authored by McIntosh] overreaches the available research data, doing
so by remarkable omissions and over-generalizations. The voluminous literature on the
role of fathers in early childhood was barely touched upon. Monotropy was reified,
despite its being an idea unsupported by empirical evidence. The serious attention many
researchers have given to the attachment capabilities of both parents was virtually
unmentioned. Serious losses of childhood were confounded with trivial ones.”).

parents who respond consistently, affectionately, and sensitively to their needs.
But infants and toddlers do not need, and most do not have, either parent’s full-
time, round-the-clock presence. Many married mothers work night shifts that keep
them away from their infants and toddlers at night without damaging their
children’s secure attachment or their development. As a result, most mothers
separated from the other parent should have no reason to worry about leaving
their children in the care of the other parent.
To maximize infants’ chances for a secure lifelong bond with both parents,
public policy should encourage both parents to actively participate in daytime and
overnight care of their young children. Scholars who study the benefits of
children’s relationships with both parents find no empirical support for the belief
that mothers are more important than fathers in their infants’ and toddlers’ lives.
In short, after their separation, both parents, in most circumstances, should seek to
maximize the time they spend with their young children, including the sharing of
overnight parenting time. This lays a strong foundation for parent-child
relationships and allows children to enjoy the unique and overlapping
contributions of each parent to the children’s development and well-being.
ANALYTIC GAPS BETWEEN SCIENTIFIC EVIDENCE AND
BLANKET RESTRICTIONS
An extensive knowledge base, drawn from more than four decades of research
directly relevant to this topic, informed the conclusions of the international
consensus report. The consensus report refutes the claim that a scientific
foundation exists for a general policy of limiting or discouraging young children’s
overnights with one parent when their parents live apart. Those who advocate
such a policy often cite two studies to support their concerns about the risks of
shared parenting and overnights for children under the age of four.
The first study was a 2010 report written by McIntosh, Smyth, and Kelaher,
issued by the Attorney General’s department in Australia, and copyrighted by a
clinic founded by the study’s first author.
12
The second study, by Tornello et al.,
was published in 2013.

The consensus report identified significant problems and
limitations in both studies that should affect the admissibility and weight of

testimony that relies on these studies.
14
The U.S. Supreme Court in
General
Electric Co. v. Joiner
noted: “[C]onclusions and methodology are not entirely
distinct from one another. . . . A court may conclude that there is simply too great
an analytical gap between the data and the opinion proffered.”
15
The analytical
gap metaphor offers a useful critique of some experts who have expressed
opinions based on these two studies. Understanding several kinds of gaps in the
testimony of these experts should inform trial examinations of the reports and
testimony of these experts.
16
Gaps Between Research Participants and Custody Litigants
One obvious and wide gap between the findings from these two studies and
expert witness testimony is the difference between the populations studied and
typical custody litigants. The Australian study’s sample is not representative of
parents who are going through a divorce because most of the parents in the study
were never married to each other (90% for the sample of infants and 60% for
toddlers), and 30% had never even lived together. Nothing is known about the
behavior and relationships between the parents and children prior to the couples’
separations. Even if the study reached verifiable conclusions, the differences
between Australian children of unmarried fathers who may or may not have had
any pre-separation relationship with their children and American children whose
married parents are divorcing and who are accustomed to their fathers’ care is too
wide a gap to bridge. The consensus report affirmed that optimal parenting plans
are different for children who have a pre-existing relationship with both parents
and those who do not.
The second study similarly focused predominantly (85%) on children whose
parents had never been married or lived together (30%). Tornello et al.’s sample
was even less typical than the Australian sample of most parents who take a
custody dispute to trial or who mediate a settlement with lawyers. The study’s
data came from the Fragile Families sample of inner-city children born in
impoverished circumstances: 62% of the age 1 sample lived below the poverty
line, 60% of the parents were imprisoned before the children’s fifth birthdays,
85% were Black or Hispanic, 65% had parents who had nonmarital births from
more than one partner in their teenage or young adult years, and nearly two-thirds
had not completed high school.
17
In sum, even if the results from these two
studies are trustworthy their relevance to U.S. custody disputes is slim.

Gaps Between Methodology and Conclusions
In-depth analyses of the McIntosh et al. study, published in the consensus
report and in other papers, reveal multiple problems in the study’s measures,
procedures, data analyses, and data reporting—problems that expose wide gaps
between the study’s methodology and conclusions and between the data reported
and opinions based on the data. Two examples of analytic gaps that undermine the
trustworthiness of the study’s conclusions are found in one sentence from the
synopsis: “Infants under two years of age living with a nonresident parent for only
one or more nights a week were more irritable and were more watchful and wary
of separation from their primary caregiver than those primarily in the care of one
parent.”
18
The first author subsequently described these negative outcomes as “a
cluster of stress regulation problems.”
19
Only in the Appendix of the 169-page report can readers discover that the
irritability score for babies with no overnights actually is slightly worse than the
score for babies who spent one or more nights per week with their other parent.
20
Also, the mean irritability score for the frequent overnighters and the infants in
intact families was identical, and the mean irritability score for all groups was
within the normal range. Since, for these researchers, the irritability scores
generated such concern about “stress regulation” for overnighting infants, they
should have expressed equal concern about infants being raised in intact, two-
parent Australian homes.
Another problem with generalizing from the McIntosh et al. sample—other
than the gap between the composition of the sample and most parents who are
separating—is the study’s tiny sample sizes. The result reported for irritability of
infants with occasional overnights was based on a sample of 14 infants. Only 11
infants saw their fathers on a schedule that would fit standard definitions of
shared parenting. The sample size for the group of 2- to 3-year-olds with frequent
overnights ranged from 5–25 depending on the variable analyzed (e.g., 5 subjects
for a rating of conflict with the child made by teachers and daycare attendants).
An analysis based on five respondents is unlikely to provide meaningful data.
21
The second analytic gap revealed in the sentence quoted from the synopsis is
the discrepancy between a substandard measure and the conclusion based on the
results from that measure. The synopsis concluded that the overnighting infants

were more “watchful and wary of separation from the primary caregiver.”
22
The
implication is that overnighting had somehow damaged the security of the babies’
relationships with their mothers. This conclusion, repeatedly cited to discourage
overnights for children younger than two years of age, came from three questions
that the researchers extracted from a standardized scale designed to measure
young children’s cognitive development. The resulting non-standard measure is
unreliable in the sense that it is untrustworthy as an index of what it purports to
measure.
23
Scientists take pains to ensure that the measures they use are properly
calibrated so that the results can be trusted. Scales need to yield consistent results,
known as the instrument’s
reliability,
and the instrument must measure what it is
intended to measure, known as its
validity.
McIntosh and her team used scales
with insufficient, if any, indications of reliability or validity. For instance, without
adequate calibration a scale that lacks reliability can one day show a readout of
ten pounds for a ten-pound package, and the next day show a readout of fifty
pounds for the same ten-pound package. If the scale lacks validity, the scale can
be off by five pounds even though it might reliably show the same incorrect
weight every time you weigh the package.
A central concern with both the McIntosh et al. and the Tornello et al. studies
is their use of sub-standard measures and reliance on results of those measures to
draw unwarranted inferences. The Warshak consensus report observed that none
of the four significant outcomes reported by McIntosh et al. were derived from
measures that met basic scientific standards,
24
a point also noted by Nielsen in
greater detail.
25
McIntosh et al. concluded that a child under the age of two who spends more
than three nights a month with dad is more likely to have “emotional regulation”
problems reflected in the child’s “insistent visual monitoring” of the mother.
26
To
measure this, the study asked each mother (only about four percent of the
respondents were fathers) three questions: does your child sometimes or often try
to get your attention, look to see if you are watching her or him at play, and try to
get you to notice other objects?
27
There was no rating of “insistence.” The authors
made the dubious assumption that because infants when anxious look at their
mothers and try to get her attention, being anxious is the only reason infants look
at their mothers, and that the more infants look at their mothers, the more anxious

of behavior problems with the mother, abridged from a standard measure, had no
measure of reliability or validity for the new instrument.

the infants must be. This error in logic is known as affirming the consequent. No
one, including McIntosh et al., has ever shown that these three questions yield
reliable information—would the answers be the same a week later? Nor have
McIntosh et al. shown that the questions yield valid information having anything
to do with a baby’s emotional health, anxiety, ability to manage stress, or ability
to regulate emotions. In fact, the three questions were extracted from a longer
instrument that has been validated as a measure of how ready the child is to learn
to talk. More frequently looking at the mother and trying to her attention indicates
advanced cognitive development, not impaired emotional regulation as McIntosh
et al. stated.
28
Similarly, Tornello et al. assessed the child’s attachment to the mother with a
measure that had no established reliability or validity. The Warshak consensus
report and other scholars have questioned the validity of the attachment measure
and the meaning of findings based on the measure because the instrument was
completed by mothers rather than by trained professional raters.
29
Other
researchers using this same attachment measure have acknowledged that it lacks
objectivity,
30
which is an important factor in determining the admissibility and
weight of opinions based on this measure.
Tornello et al. acknowledged that their measure of attachment was
questionable, but nevertheless reported that children who at age 1 had frequent
overnights (1 to 5 overnights per week) were more likely than those with some
overnights to be insecurely attached to their mothers at age 3. The press release

account for the fact that all the groups of children rated by their mothers in the Tornello
et al. study had lower percents of insecure attachment than what would be expected for
these children who were living in poverty with poorly educated mothers.

unreliability of the attachment measures, incorrectly claimed that infants who
spent at least one night per week away from their mothers had more insecure
attachments than babies who saw their fathers only during the day. In fact they
did not.
31
Gaps Between Data and Interpretation
Even overlooking that Tornello et al. used a nonstandard attachment measure
administered in a nonstandard manner, the results were ambiguous. Insecurity in
the infants was more common among the frequent overnighters, followed by the
never overnighters, followed by the occasional overnighters. A similar, nonlinear
pattern characterized the McIntosh et al. results.
32
Thus, as the Warshak
consensus report and others have noted, frequency of overnights did not predict
insecurity in either study.
33
Interpreting the attachment findings is complicated by another fact that
Tornello et al. did not report: More than half of the infants classified as frequent
overnighters lived predominantly with their fathers. But the data were reported
and interpreted as if the mother was always the “resident” parent and the babies
were overnighting with a “nonresident” father. Thus the “resident” and
“nonresident” parents were mislabeled. Without knowing more about why these
babies were living with their fathers it would be a mistake to assume that frequent
overnights in their fathers’ home caused the children’s insecure attachment to
their mothers. The gap between the data and the conclusion is too wide to bridge.
The mothers in this sample were drawn from a population of women who had
higher rates of substance abuse, depression, and incarceration.
34
These factors and
others, such as domestic violence, affect the quality of parent-child relationships.
Even if the attachment measure had met scientific standards, these results should

not be relied upon in making decisions about parenting plans for most divorcing
parents, especially for parents with the resources to take a custody dispute to trial
or to hire lawyers to negotiate and mediate out-of-court settlements.
Additional Gaps Between Data and Opinions
Policy makers, decision makers, and expert witnesses who rely on the data
from these two studies to discourage overnight parenting plans for young children
often fail to mention the results from these two studies that do not support this
conclusion, in addition to the significant limitations discussed above that
undermine their usefulness as a basis for custody decisions. For instance, one of
the authors of the Tornello et al. study recently coauthored a chapter which
provided this interpretation of their study’s results: “Spending frequent overnights
[with fathers] between the ages of 1 and 3 years did not predict attachment
insecurity at age 3 but did predict positive behavior at 5 years of age.”
35
Yet
Tornello et al. cautioned that the link between overnights and positive behavior—
derived from a standard, well established instrument with strong evidence for its
reliability and validity and administered in the standard manner—could be due to
chance. Tornello et al. did not mention this positive finding for overnights in the
article’s Abstract. Instead the authors placed more confidence in the finding
linking overnights to attachment insecurity, despite having acknowledged the
uncertain trustworthiness of the attachment measure.
Furthermore, experts who rely on these two studies should be aware that data
were available only from one parent, not both. Yet reports of mothers and fathers
about their children’s wellbeing often vary significantly as previous research has
demonstrated.
Given the wide gap between the circumstances and characteristics of the
parents in these two studies and those of most separating parents (especially
custody litigants), the gaps between the flawed measures and the conclusions
drawn from those measures, and the gaps between the actual data and opinions
proffered about the data, the Warshak consensus report agrees with other
scholars
36
that these two studies provide no reliable basis to support custody

CONFLICT AND PARENTING PLANS
A common response to research that finds positive outcomes for children and
parents in shared physical custody and overnighting arrangements is to challenge
the relevance of that research for parents who litigate custody or display high
levels of conflict when interacting with each other.
38
Some psychologists dismiss
the positive outcomes found in these shared parenting studies as relevant only to
those couples who voluntarily agree to share physical custody from the outset.
Their hypothesis is that couples who settle out of court for shared physical
custody begin with lower levels of conflict and that the same factors that play a
role in their agreeing to share custody may also contribute to the positive
outcomes for the children in these families.
This hypothesis lacks empirical support. The Stanford Child Custody study
39
found that children in joint physical custody (living at least one-third of the time
with their fathers) compared with children in sole physical custody were most
satisfied with the custody plan and showed the best long-term adjustments, even
after controlling for factors that might predispose parents to select joint physical
custody (such as education, income, and initial levels of parental hostility).
40
In
fact in 80% of the joint physical custody families one or both parents initially did
not want and did not agree to the arrangement.
41
Other studies found that parents
with joint physical custody had no less conflict than those with sole physical
custody.

The consensus report cited a 2011 keynote address by Martindale as an example of
support for this position, however in a personal communication Martindale clarified that
in using the phrase “joint custody” he was referring to shared decision-making authority
and not shared physical custody arrangements. Nevertheless, others have discounted the
relevance of shared physical custody research for parents in conflict.

A meta-analysis of 33 studies also reported better emotional, behavioral, and
academic functioning for children in joint physical custody compared to children
in sole custody, regardless of the level of conflict between parents.
43
Studies that
measured the amount of the father’s parenting time found that more time with the
father is not associated with poorer child outcomes in high-conflict families (with
the exception of families where there is violence or abuse).
44
In a large-scale
Australian study (not the one critiqued earlier), one to two years after separation,
conflict was neither more nor less damaging for children in shared care-time
arrangements than for children in other custody arrangements (with the exception
of reports by mothers who had concerns about children’s safety in the care of the
father).
45
Rather than magnify harmful effects of parental conflict, several studies
suggested that shared parenting may protect children from some of its negative
consequences.
46
One way in which shared parenting time can reduce children’s exposure to
tension-filled communications between parents is that spending longer periods of
time with each parent reduces the number of transfers between parents. For
instance, spending two hours with one parent and then returning to the other
parent’s home the same day means the child makes two transitions in one day.
Simply extending the two-hour evening contact into an overnight reduces the
transitions between homes to only one per day.

Should Parental Conflict Trump Shared Parenting Time?
A policy of automatically restricting children’s time with one of the parents
when a couple is labeled as “high conflict” brings additional drawbacks and
deprives children of the protective buffer of a nurturing relationship with one of
their parents.
47
This policy sends parents the message that generating or sustaining
conflict can be an effective strategy to override shared custody.
48
This discourages
civil communication and cooperation, and may reduce children’s time with the
parent who is less angry, who does a better job of shielding the children from
conflict, and who recognizes and supports the children’s need for positive
relationships with both parents.
49
Any policy that encourages the instigation and
maintenance of conflict between parents by suggesting that such behavior might
be rewarded with more parenting time puts the needs of the children second to the
desires of whichever parent opposes sharing parenting time. Such a policy
contradicts the best-interest standard whose primary purpose is to ensure that the
child’s welfare trumps parental entitlements.
50
A policy focused on children’s best
interests will decrease the risks of harm to them by discouraging rather than
encouraging inter-parental conflict.

(2004) “Some authors (e.g., Emery, 2004) have recommended that when the
co-parental relationship is highly conflicted that children’s time with one of the parents
should be restricted as a way of reducing the impact of conflict on the children. Since
mothers are most often the ‘primary’ parent and the fathers the non-resident parents, such
a recommendation is likely to disproportionately reduce father-child time. It also ignores
the reality that mothers are just as often impaired in their functioning and are as hostile as
fathers, but nevertheless are designated the primary residential parent. Relying on more
current research, others have argued that this broad policy recommendation will deny
children adequate time with supportive, competent fathers. The Emery proposal does not
differentiate the type of conflict, consider whether the child is exposed to the conflict,
identify the parent primarily fueling the conflict, and consider the parenting skills and
mental health of each parent. Moreover, such a recommendation ignores the fact that the
majority of parents with high conflict after separation substantially diminish their conflict
in the first and second year after final court orders (citations omitted).”

When considering the impact of parental conflict on the most beneficial
parenting plans for children, it is important to recognize the heterogeneity of the
dynamics of inter-parental conflict.
52
The label
high conflict couple
implies that
both parents actively engage in conflict. Although this is true in some cases, in
other cases the label is a misnomer because one parent may be a victim of the
other parent’s rage or attempts to marginalize the parent’s role in raising the
child.
53
In some cases the amount, intensity, and type of conflict resembles the
level and type of disagreements over child-rearing decisions that occur normally
between married or cohabiting parents who have different opinions about what is
best for the child.
Recommendations to Reduce Children’s Exposure to Parental
Conflict
Because of the consistency of findings that children are more likely to suffer
worse outcomes when their parents use them as pawns or when they consistently
witness, their parents’ frequent, intense, and ongoing conflict,
54
the Warshak
consensus report recommended the following:
55
When feasible, parents should be encouraged to create parenting
plans through a collaborative, nonadversarial process, that
increases the likelihood that both parents will be satisfied with the
plan and can give it relatively unambivalent support.
Interventions such as mediation and parenting coordination can
help parents better manage conflict and reduce its negative impact
on children.
When considering the implications of conflict for custody
dispositions, courts, operating under the best-interest standard, can
hear evidence that goes beyond identifying the presence of conflict
and sheds light on the dynamics of the conflict, the contributions
of each party to it, and the quality of parenting.

Where tension and conflict accompany transfers of children from
one home to the other, rather than reduce children’s time with one
parent as a response to concerns about parental conflict,
consideration should be given to conducting transfers at neutral
sites where both parents are not present at the same time.
56
For
instance, the children can be dropped off at daycare by one parent
and picked up by the other. This protects children from exposure to
parental conflict.
To the extent that conflict is generated by a father who opposes the
mother’s efforts to marginalize his participation in raising the
young child, efforts should be made to educate the mother about
the benefits to children of parenting plans that give more
opportunities for the development and strengthening of father-
child relationships and that keep fathers more involved.
Both parents should be encouraged to understand the emotional
difficulty that can attend being apart from a young child for
extended time periods, difficulty that is multiplied when a parent’s
employment keeps him or her away from the child for most of the
weekdays. Parents should be encouraged to provide regular
feedback to each other about the young child’s routines, behavior,
and health, and to the extent possible assuage each other’s
concerns about the child’s development when in the care of the
other parent.
INTERNATIONAL EXPERT CONSENSUS RECOMMENDATIONS
57
The endorsers of the parenting plans consensus report, all accomplished
researchers or practitioners, agree that the current state of the scientific literature
supports the following conclusions and recommendations. This statement should
provide strong direction for policy guidelines and decision-making.
1. Just as we encourage parents in intact families to share care of their
children, we believe that the social science evidence on the
development of healthy parent-child relationships, and the long-
term benefits of healthy parent-child relationships, supports the
view that shared parenting should be the norm for parenting plans
for children of all ages, including very young children. We
recognize that some parents and situations are unsuitable for
shared parenting, such as those mentioned in point #7 below.
2. Young children’s interests benefit when two adequate parents
follow a parenting plan that provides their children with balanced

19
and meaningful contact with each parent while avoiding a template
that calls for a specific division of time imposed on all families.
3. In general the results of the studies reviewed in this document are
favorable to parenting plans that more evenly balance young
children’s time between two homes. Child developmental theory
and data show that babies normally form attachments to both
parents and that a parent’s absence for long periods of time
jeopardizes the security of these attachments. Evidence regarding
the amount of parenting time in intact families and regarding the
impact of daycare demonstrates that spending half time with
infants and toddlers is more than sufficient to support children’s
needs. Thus, to maximize children’s chances of having good and
secure relationships with each parent, we encourage both parents to
maximize the time they spend with their children. Parents have no
reason to worry if they share parenting time up to 50/50 when this
is compatible with the logistics of each parent’s schedule.
4. Research on children’s overnights with fathers favors allowing
children under four to be cared for at night by each parent rather
than spending every night in the same home. We find the
theoretical and practical considerations favoring overnights for
most young children to be more compelling than concerns that
overnights might jeopardize children’s development. Practical
considerations are relevant to consider when tailoring a parenting
plan for young children to the circumstances of the parents.
Overnights create potential benefits related to the logistics
of sharing parenting time. Parents of young children are more
likely than parents of older children to be at an early stage in their
career or employment at which they have less flexibility and
control over their work schedules. Parenting schedules that offer
the father and child 2-hr blocks of time together, two or three times
per week, can unduly stress their contacts. Overnights help to
reduce the tension associated with rushing to return the child, and
thus potentially improve the quality and satisfaction of the contact
both for the parent and child. Overnights allow the child to settle in
to the father’s home, which would be more familiar to the child
who regularly spends the night in the home compared with one
who has only one-hour segments in the home (allowing for
transportation and preparation for the return trip). Spending the
night allows the father to participate in a wider range of bonding
activities, such as engaging in bedtime rituals and comforting the
child in the event of nighttime awakenings. An additional
advantage of overnights is that in the morning the father can return
the child to the daycare; this avoids exposing the child to tensions
associated with the parents’ direct contact with each other.
Nonetheless, because of the relatively few studies currently
available, the limitations of these studies, and the predominance of

Stemming the Tide of Misinformation
20
results that indicate no direct benefit or drawback for overnights
per se outside the context of other factors, we stop short of
concluding that the current state of evidence supports a blanket
policy or legal presumption regarding overnights. Because of the
well-documented vulnerability of father-child relationships among
never-married and divorced parents, and the studies that identify
overnights as a protective factor associated with increased father
commitment to child rearing and reduced incidence of father drop-
out, and because no study demonstrates any net risk of overnights,
decision makers should recognize that depriving young children of
overnights with their fathers could compromise the quality of their
developing relationship.
5. Parenting plans that provide children with contact no more than six
days per month with a parent, and require the children to wait more
than a week between contacts, tax the parent-child relationships.
This type of limited access schedule risks compromising the
foundation of the parent-child bond. It deprives children of the
type of relationship and contact that most children want with both
parents. The research supports the growing trend of statutory law
and case law that encourages maximizing children’s time with both
parents. This may be even more important for young children in
order to lay a strong foundation for their relationships with their
fathers and to foster security in those relationships.
6. There is no evidence to support postponing the introduction of
regular and frequent involvement, including overnights, of both
parents with their babies and toddlers. Maintaining children’s
attachment relationships with each parent is an important
consideration when developing parenting plans. The likelihood of
maintaining these relationships is maximized by reducing the
lengths of separations between children and each parent and by
providing adequate parenting time for each parent. Such
arrangements allow each parent to learn about the child’s
individual needs and to hone parenting skills most appropriate for
each developmental period. The optimal frequency and duration of
children’s time with each parent will differ among children,
depending on several factors such as their age and their parents’
circumstances, motivations, and abilities to care for the children.
Other important considerations include children’s unique
relationship histories with each parent and their experience of each
parent’s care and involvement. In each case where it is desirable to
foster the parent-child relationship, the parenting plan needs to be
sensitive to the child’s needs, titrating the frequency, duration, and
structure of contact.
7. Our recommendations apply in normal circumstances, for most
children with most parents. The fact that some parents are
negligent, abusive, or grossly deficient in their parenting—parents

whose children would need protection from them even in intact
families—should not be used to deprive the majority of children
who were being raised by two loving parents from continuing to
have that care after their parents separate.
AFTERMATH OF THE CONSENSUS REPORT
The list of endorsers and their stature and accomplishments reflect the field’s
general acceptance of the consensus report’s findings as rooted in settled science
from more than four decades of research directly relevant to this topic, including
seminal studies by many of the endorsers. This research “provides a growing and
sophisticated fund of knowledge about the needs of young children, the
circumstances that best promote their optimal development, and the individual
differences among children regarding their adaptability to different circumstances,
stress, and change.”
58
The endorsements reflect agreement that the report’s
conclusions and recommendations are well grounded, generally accepted in the
field, and expressed in measured language that is useful to decision makers.
Recent Studies
After the Warshak consensus report was published, two new studies lent
additional weight to the report’s conclusions. Reanalyzing the data set used by
Tornello et al., Sokol examined the correlation between the absolute number of
overnights with father and the incidence of insecure attachments to mother. In her
preliminary findings, Sokol found no correlation and concluded that overnights
with father do not harm the mother-child relationship.
59
Fabricius reported long-term benefits to college students who, in the first three
years of life, spent overnights with their fathers after their parents separated.

Current Literature and Re-analyses. Address at the Association of Family and
Conciliation Courts Annual Conference (May 31, 2014). Sokol’s study was presented at a
professional conference and the results have not yet appeared in a peer-reviewed journal
article. In using the absolute number of overnights, rather than categories of overnight
frequency, Sokol avoided potential problems in Tornello et al.’s methodology which
grouped together infants who spent one overnight per week with their fathers with those
who lived primarily with their fathers (up to five nights per week). Tornello’s group
analyses apparently obscured differences in mother-custody versus father-custody
families that affect the results. Note that the composition of the sample and the problems
with the attachment measure reported by Tornello et al. (discussed

Sokol’s study and its relevance to most separating parents.

did those who had been deprived of overnights early in their lives. They had
better relationships with their fathers at no cost to the quality of their relationships
with their mothers. On the other hand, having fewer overnights with fathers
during infancy was associated with more long-term harm to the father-child
relationship. Also, there were no indications of any long-term stress-related health
problems related to overnight parenting time for infants with their fathers.
61
The
study concluded: “[I]nfant behaviors that have caused the concern about overnight
parenting time are either temporary, or they do not signal the long-term effects
that were feared.”
62
And, “Of much greater concern is the substantial detriment to
the long-term father-child relationship associated with lack of overnight parenting
time with fathers. . . .”
63
Overall the study concluded, “We see long-term risks to
the father-child relationship in the absence of overnight parenting time during the
first 3 years, but only benefits to both parents with the presence of overnight
parenting time.”
64
And, “Maximizing parenting time protects children from harm
to the father-child relationship, from harm to the mother-child relationship, and
from harm due to parent conflict.”
65
Reactions to the Consensus Report
In addition to the 110 researchers and practitioners behind the consensus
report, prominent social scientists, such as Joan Kelly, cited the report favorably
in their presentations and literature reviews.
66
The paper has been translated into
at least eighteen languages and has informed legislative deliberations throughout
the U.S. and parliamentary deliberations in several countries including the United
Kingdom, Canada, Israel, Finland, Romania, Croatia, and Sweden. Two years
after its publication the consensus report continues to be one of the most
downloaded papers from the journal’s website.

at 9, agreed with Warshak et al.,
supra
note 11,
on the important issue of whether young children develop an attachment hierarchy in
which mothers are predominant: “Consistent with other recent studies, there was no
support for the primacy of the mother as an attachment figure in predicting future
outcomes. Nor was there support for the belief that infants and toddlers have a gender
bias in attachment formation or develop an attachment hierarchy in which mothers are
consistently preferred.”

endorsers of the consensus report: “When both parents have established
significant attachments and both have been actively involved in the child’s care,
research suggests that overnight visits will consolidate attachments and child
adjustment, not work against them.”
67
“Children whose parents were both highly
involved before separation benefit from continued involvement with both parents.
That involvement should include overnight contact with nonresident parents when
there is a preseparation history of involvement.”
68
It was anticipated that some colleagues would disagree with the consensus
report opinions and recommendations. But in the two years since its publication,
no article, including those by McIntosh et al., has explicitly identified any errors
in the report or disputed any of its conclusions and recommendations. Confronted
with the critiques of their studies, one might expect researchers either to show
where the consensus report and other scholars’ critiques are mistaken or to modify
their previous interpretations of their data and communicate their amended
conclusions to colleagues and the general public.
McIntosh et al. have not yet acknowledged or addressed concerns about three
of the four measures in their study. But after the consensus report was published,
they conceded in one article that their 3-item visual monitoring scale has
“relatively low” reliability and is a “weak link” in their study.
69
Otherwise, Smyth
and McIntosh have ignored the critiques that their measures were untrustworthy.
To date, McIntosh et al. have not acknowledged that: 1) the results that raised
their concern about overnights and young children’s ability to regulate stress rest
on a flimsy foundation and do not stand up to scrutiny, 2) the substandard
measures used in their study do not support trustworthy conclusions, and 3) the
infants with frequent overnights looked no worse than those with no overnights.
Instead, McIntosh et al. have continued to report that the infants in their study
with weekly overnights had “higher levels of emotionally dysregulated
behaviors”
70
and showed “a greater cluster of stress regulation problems
compared with infants with fewer overnight stays,” and that “regardless of the
context of their parents’ separation, more frequent overnight stays might be more
challenging for emotional regulation processes in young children under 4 years of
age than for children aged 4 years and over.”
71
These continued assertions of
McIntosh et al. are the equivalent of reporting an object’s weight on a broken
scale whose readout cannot be trusted, while concealing the fact that the scale is
faulty.
In response to the consensus report and other critiques, McIntosh et al. have
tried to bolster confidence in the ”veracity and reliability” of their study’s
findings, by repeatedly claiming that other studies, such as the one by Tornello et
al., replicated their study.

24
measures with a different population in their study. Further, as previously noted,
Sokol’s preliminary analysis of the data in Tornello et al. found no correlation
between overnights and insecure attachments in infants.
73
However, McIntosh et
al., in a significant concession, noted that their findings “do not substantiate
cautions against
any
overnight care in healthy family circumstances.”
74
This
acknowledgment is another sign that the consensus report is achieving its primary
goal of stemming the tide of misinformation.
Pruett (who coauthored a 2014 article with McIntosh on overnights) et al.
issued a statement very similar to that of McIntosh and her coauthors. Pruett et al.
(2016) wrote that “results from these studies do not substantiate cautions against
any
overnight care or overnight care for
all
children during the first 3 years.”
They added, “Overall it is clear that these studies do not tell us enough to make
policy recommendations against overnights; they leave us only with cautions
about what to study in order to know more about how these types of transitions
affect children in different situations differently.”
75
Despite these general statements, Pruett and McIntosh, writing with Kelly in
2014, nonetheless concluded that sufficient basis exists for certain cautions about
overnights, noting that “the small group of relevant studies to date substantiates
caution about high frequency overnight time schedules in the 0-3 year period,
particularly when the child’s security with a parent is unformed,
or parents
cannot agree on how to share care of the child.”
76
But at the outset of their article,
under the heading “Key Points for the Family Court Community,” the authors
narrow the criteria for cautions against high frequency overnights:
Cautions against overnight care during the first three years are not
supported. The limited available research substantiates some
caution about higher frequency overnight schedules with young
children, particularly when the child’s relationship with a second
colleagues conducted an investigation similar to ours, using a large U.S. sample of
children. They replicated many of the Australian findings. Specifically, they found: . . .
(b) ‘frequent infant overnights were significantly related to attachment insecurity
assessed at age 3’. . . ” (citations omitted)). Yet McIntosh et al.,
id.,
at 112, state clearly
that their study did not measure attachment (“Our study, however, was not a study of
attachment.” And, “We did not, and could not examine attachment, simply because
attachment data were not part of the longitudinal dataset we employed, namely the
Longitudinal Study of Australian Children.”)

parent has not been established and/or parents are in frequent
conflict
to which the child is exposed.
77
The last six words of the above statement make a significant difference. In
practice, a blanket policy that cautions against overnights for a young child whose
parents do not agree on custody discourages courts from ordering shared
parenting and overnights in litigated cases. By contrast, a policy that discourages
overnights only if the child is exposed to frequent conflict, means that courts need
to consider the impact of conflict on the child, a practice recommended by the
Warshak consensus report.
78
Because of the significant difference in the two
statements by Pruett, McIntosh, and Kelly about conflict and overnights, it is not
clear which position the authors intended to guide “the family court community.”
Perhaps the difference between the two recommendations in the same article
reflects differences among the three coauthors. In her previous and subsequent
work, Kelly argued against reducing the child’s time with the father or reducing
the father’s caregiving for the child at bedtime, when the child awakes during the
night, and in the morning. Instead Kelly promoted other solutions that reduce the
child’s exposure to conflict.
79
By contrast, McIntosh offers on her website a chart and profile (CODIT) to
guide parents and professionals making overnight decisions.
80
Although not
intended for use as a diagnostic instrument or as the sole basis for decisions this
document asserts, “Even when all parenting conditions are met, high numbers of
overnights (more than weekly) are not generally indicated for young infants 0-18
months subject to family law disputes.”
81
This guideline sets up a rebuttable
presumption against more than one overnight per week for children younger than
18 months even with parents who consistently and sensitively meet the children’s
needs.

week with their fathers for the first one-and-a-half years. To frustrate the father’s
desire to have a larger role in bedtime rituals and morning routines the mother
need only register an objection, thus creating a custody dispute. The mother’s
preference prevails even if her motives are vindictive, even if her objection is
capricious, and even if the father demonstrates superior parenting.
The CODIT includes subjective rating scales with no known reliability or
validity. For instance, child adjustment is rated using criteria such as “excessive
clinging on separation,” “frequent crying,” “aggressive behavior,” and “low
persistence in play & learning” with no anchors to distinguish between troubling
behavior within normal limits and atypical behavior. Including such factors in a
tool to guide overnight decisions reflects an assumption that troubling behaviors
in an infant or toddler that persist more than two weeks are associated with—and
can be eliminated by—restricting one parent’s overnight contact with the child.
The CODIT includes multiple factors that allow gatekeeping parents to use this
tool to restrict their children’s overnights with the other parent.
Two years after their coauthored article Pruett came out in favor of a position
more in line with her previous coauthor Kelly. Writing without McIntosh, but
with five other coauthors, Pruett significantly amended her statement about
parental conflict:
The small group of relevant studies to date substantiates caution
about
high-frequency
overnight time schedules in the 0– to 3–year
period when the child’s relationship with a parent is not established
(e.g., parents never lived together and nonresidential parent spent
little to no time with the baby), or when parents cannot agree on
how to share care of the child
and their conflict interferes with the
child’s care.
82
(second emphasis added).
These six authors are among the scholars who agree with the consensus report’s
conclusion that the mere presence of conflict between parents over how to share
care of their child (i.e., a dispute over custody) is not a sufficient reason to be
cautious about overnights. Instead, decision makers should attend to the nexus
between the expressions of conflict and their impact on the child.
Misunderstandings of the Consensus Report
Pruett et al. (2016) hold the same position as the Warshak consensus report
about the importance of the coparenting relationship when considering decisions
about shared parenting. Yet Pruett et al. left the appearance of disagreement when
they mistakenly reported:
Warshak (2014) argues that children benefit from a more evenly
balanced amount of time between parents, and that this should be

protected regardless of the co-parenting dynamic, since reducing
one parent’s time in the face of conflict favors the parent with
more access as that parent can perpetuate conflict as an excuse not
to share parenting. This may be true, but it ignores the needs of the
infant or toddler from a child-centric perspective, if the shared
parenting results in the child’s consistent exposure to conflict.
83
The consensus report offered no such generalization or rationale for shared
parenting. And as explained earlier, because a blanket policy prioritizes parents’
desires over children’s needs, such a policy of reducing a child’s time with a
parent when the parents are in conflict is hardly “child-centric.”
84
A blanket
policy provides an incentive to a parent to escalate and involve children in
conflict if the parent believes that initiating and sustaining conflict is a path to
winning sole physical custody.
85
In many cases there are better ways to protect a
child from consistent exposure to conflict than to disproportionately deprive the
child of important time with a parent.
86
Contrary to Pruett et al.’s (2016) assertion, the consensus report explicitly
identified coparenting dynamics as one among several factors to consider in
reaching a custody decision, a position that Warshak has consistently held in his
publications during the past twenty-five years.
87
Naturally, shared parenting and
overnighting are not for all families. On this point the consensus report is clear:
Some circumstances depart significantly from the norm and do not
lend themselves to the same general recommendations that apply
to the majority of parenting plan decisions. These circumstances
include a history of intimate partner violence, a history or credible
risk of neglect, physical abuse, sexual abuse, or psychological
abuse toward a child, manifestations of restrictive gatekeeping
such as persistent and unwarranted interference with parenting

time (Austin, Fieldstone, & Pruett, 2013; Pruett, Arthur, & Ebling,
2007; Pruett et al., 2012; Warshak et al., 2003), a history of child
abduction, a child’s special needs (e.g., cystic fibrosis or autism),
and a significant geographical separation between the parents.
88
Note that in stressing the importance of coparenting dynamics, the consensus
report cited three of Pruett’s articles. The report unambiguously and repeatedly
acknowledged the importance of the coparenting relationship and specifically
recommended that courts not only identify the presence of conflict, but also
consider evidence that “sheds light on the
dynamics of the conflict,
the
contributions of each party to it, and the quality of parenting.”
89
And, “our
recommendations apply to children who have a relationship with both parents. If a
child has a relationship with one parent and no prior relationship with the other
parent, or a peripheral, at best, relationship, different plans will serve the goal of
building the relationship versus strengthening and maintaining an existing
relationship.”
90
Pruett et al. (2016) also misunderstood why the consensus report opposed a
blanket policy of allowing one parent to veto joint physical custody merely by
claiming a conflicted relationship with the other parent. The consensus report’s
opposition to such a policy has nothing to do with a concern that it rewards the
parent who has more contact with the children. The consensus report proposed
that conflict between parents does not automatically eliminate the possibility that
children can benefit from shared parenting. Warshak and the endorsers of the
consensus report favor a policy that protects children by reducing a parent’s
motivation to initiate, sustain, and escalate conflict. Again, this has nothing to do
with favoring one parent over the other. Indeed, there is no reason to assume that
such a policy would favor the parent who perpetuates conflict. By statute a
majority of states instruct courts to consider coparenting behavior (using various
labels for the concept) as one factor in determining the custody arrangement that
serves the children’s best interests. The parent who perpetuates conflict may find
that such behavior, rather than reducing the other parent’s time with the children,
has the opposite outcome.
91
Braver and his colleagues found that the public favors
a policy that would reduce parenting time for the parent who is identified as the
primary instigator of conflict.

Instead of a blanket policy that denies children the potential benefits of shared
parenting, the consensus report offers recommendations to protect children from
consistent exposure to conflict.
93
These recommendations are applicable in
situations where parents share overnights and in situations where children live
predominantly with one parent and see the other parent less frequently (e.g., a
schedule of every other weekend and mid-week contacts with or without
overnights).
Pruett et al. (2016) leave the impression that they dissent from the consensus
report on the important role of the coparenting relationship and the importance of
the child’s prior relationship with a parent when in fact their position reiterates the
consensus view. Indeed, Pruett et al.’s seven “points of consensus” echo the
conclusions of the consensus report published two years earlier.

overnights for young children. But predominantly
the studies show little direct impact
of overnights in the short run.
The three studies that often are cited as evidence for the
harmful effects of greater father involvement with young children actually found mixed
or ambiguous results perhaps because the measures used were inadequate by scientific
standards. . . . The
research on children being raised by parents who live apart from
each other,
in the larger context of scientific knowledge about the factors that foster
optimal child development and the formation and maintenance of healthy parent–child
relationships, offers guidelines that should inform decision makers and those who assist
them, such as parents, mediators, child custody experts, lawyers, and judges.” (p. 58)

expected, none would have endorsed the paper if they agreed with the conclusions
but disagreed with the evidence that supported the conclusions. In fact, the
conclusions referred explicitly and extensively to the evidence reviewed and
analyzed in the preceding sections. Rather than enumerate the significant
contributions of the endorsers to our base of scientific knowledge, the reader is
encouraged to note the names of the scholars and their credentials listed at the end
of the consensus report. The qualifications of the endorsers to vet the literature
reviews and analyses and to judge the conclusions and recommendations that flow
from those analyses are beyond dispute.
Some have questioned the value of publishing a paper with scientists’
endorsements. But such papers are not unprecedented. An example is the 1997
article co-signed by eighteen experts that clarified implications of social science
evidence for custody arrangements.
97
Similarly, the Warshak consensus report
clarifies the social science relevant to parenting plans for young children.
Having the paper reviewed by the endorsers of the Warshak report brought
two advantages. The first was the benefit of feedback and vetting from this group
on the consensus report’s analysis of the bodies of literature on attachment,
daycare, parenting plans, and divorce. The endorsers included prominent
international authorities in attachment, principal investigators for the celebrated
NICHD Study of Early Child Care and Youth Development, and leading
researchers who have studied the impact of divorce since the mid-1970s. The
second advantage was that the statures of the signatories—with their outstanding
And, “To the extent that policy and custody decisions seek to express scientific
knowledge about child development,

significant weight by legislators and decision makers.
. . . . [W]e believe that the

science evidence
on the development of healthy parent–child relationships, and the long-
term benefits of healthy parent–child relationships, supports the view that shared
parenting should be the norm for parenting plans for children of all ages, including very
young children. . . . In general
the results of the studies reviewed in this document
are
favorable to parenting plans that more evenly balance young children’s time between two
homes.
Child developmental theory and data
show that babies normally form
attachments to both parents and that a parent’s absence for long periods of time
jeopardizes the security of these attachments.
Evidence
regarding the amount of
parenting time in intact families and regarding the impact of daycare demonstrates that
spending half time with infants and toddlers is more than sufficient to support children’s
needs. Thus, to maximize children’s chances of having a good and secure relationship
with each parent, we encourage both parents to maximize the time they spend with their
children. . . .
Research on children’s overnights
with fathers favors allowing children
under four to be cared for at night by each parent rather than spending every night in the
same home.” (p. 59) And, “The

the growing trend of statutory law
and case law that encourages maximizing children’s time with both parents. This may be
even more important for young children in order to lay a strong foundation for their
relationships with their fathers and to foster security in those relationships . . . .There
is
no evidence to support postponing the introduction of regular and frequent
involvement, including overnights,
of both parents with their babies and toddlers. . . .
Rather it is our conviction that

reliability, and thus are trustworthy in the legal sphere.

careers as social scientists—brings attention to decision makers for the report’s
conclusions and recommendations.
In sum, the consensus report does not maintain that its conclusions are
scientific merely because 110 well-qualified researchers and practitioners endorse
the conclusions—science is not settled at the ballot box. Rather, the consensus
report reflects that the endorsers, based on their understanding of the literature
and on their professional experiences, accept the report’s research-based
conclusions.
CONCLUSION
Warshak, with the review and endorsement of 110 researchers and
practitioners, analyzed more than four decades of research and issued a peer-
reviewed consensus report on parenting plans for young children.
98
As intended,
the report stemmed a tide of misinformation that was threatening to resurrect
long-discarded myths about child development and enshrine them in professional
practice and family law. The list of endorsers and their professional
accomplishments reflect the widespread acceptance of the consensus report’s
findings that favor shared parenting and overnighting for young children under
normal circumstances. Two years after its publication, the conclusions and
recommendations of the Warshak consensus report remain supported by science.
