HOMOSEXUAL PARENTING: PLACING CHILDREN AT RISK
(Part I of III)
by Timothy J. Dailey, Ph. D.
Part 1: Introduction | Problems With Homosexual Parenting Research
The presence of methodological defects - a mark of substandard research - would be cause for rejection of research conducted in virtually any other subject area. The overlooking of such deficiencies in research papers on homosexual failures can be attributed to the "politically correct" determination within those in the social science professions to "prove" that homosexual households are no different than traditional families.
However, no amount of scholarly legerdemain contained in an accumulation of flawed studies can obscure the well-established and growing body of evidence showing that both mothers and fathers provide unique and irreplaceable contributions to the raising of children. Children raised in traditional families by a mother and father are happier, healthier, and more successful than children raised in non-traditional environments.
David Cramer, whose review of twenty studies on homosexual parenting appeared in the Journal of Counseling and Development, found the following:
Since these words were penned in 1986, the number of studies on the subject of homosexual parenting has steadily grown. The fact that these studies continue to be flawed by the methodological errors warned about by Cramer has not inhibited the proponents of homosexual parenting from their sanguine assessment of the outcomes of children raised in homosexual households.
Silverstein and Auerbach, for example, see no essential difference between traditional mother-father families and homosexual-led families: "Other aspects of personal development and social relationships were also found to be within the normal range for children raised in lesbian and gay families." They suggest that "gay and lesbian parents can create a positive family context." 
This conclusion is echoed in the official statement on homosexual parenting by the American Psychological Association's Public Interest Directorate, authored by openly lesbian activist Charlotte J. Patterson of the University of Virginia:
PROBLEMS WITH HOMOSEXUAL PARENTING RESEARCH
In addition, Patterson acknowledges that "research in this area has presented a variety of methodological challenges," and that "questions have been raised with regard to sampling issues, statistical power, and other technical matters (e.g., Belcastro, Gramlich, Nicholson, Price, and Wilson, 1993)." She adds, revealingly:
Though she admits to serious methodological and design errors that would call into question the findings of any study, Patterson makes the astonishing claim that "even with all the questions and/or limitations that may characterize research in the area, none of the published research suggests conclusions different from those that will be summarized below." But any such conclusions are only as reliable as the evidence upon which they are based. If the alleged evidence is flawed, then the conclusions must likewise be considered suspect.
One suspects that the lack of studies with proper design and controls is due to the political agendas driving the acceptance of homosexual parenting, which favor inadequate and superficial research yielding the desired results.
In a study published in the Journal of Divorce and Remarriage, P. Belcastro et al. reviewed fourteen studies on homosexual parenting according to accepted scientific standards. Their "most impressive finding" was that "all of the studies lacked external validity. The conclusion that there are no significant differences in children raised by lesbian mothers versus heterosexual mothers is not supported by the published research data base."  Similarly, in their study of lesbian couples in Family Relations, L. Keopke et al. remark, "Conducting research in the gay community is fraught with methodological problems." 
A careful reading of studies used to lend support to homosexual parenting reveals more modest claims than are often attributed to them, as well as significant methodological limitations:
Inadequate Sample Size
~ After finding no significant difference between a group of nine children raised by lesbians and a similar group of children raised by heterosexual parents, S. L. Huggins admitted, "The meaning and implications of this finding are unclear, and the small sample size makes any interpretation of these data difficult." 
~ A report by J. M. Bailey et al. in Developmental Psychology, commenting on studies of the children of gay and lesbian parents, notes that "available studies [are] insufficiently large to generate much statistical power." 
~ S. Golombok and F. Tasker admit in their follow-up study of children reared by lesbians, "It is possible that the small sample size resulted in an underestimate of the significance of group difference as a result of low statistical power (Type II error)."  Elsewhere they caution that negative effects of children reared by lesbians "could have remained undetected because of the relatively small sample size. Therefore, although discernible trends were identified, caution is required in interpreting these results." 
~ In his study published in Child Psychiatry and Human Development comparing the children of homosexual and heterosexual mothers, G. A. Javaid frankly admits that "the numbers are too small in this study to draw any conclusions." 
~ J. J. Bigner and R. B. Jacobson state in the Journal of Homosexuality:
~ In her study of lesbian families, Patterson admits to sampling bias:
~ Similarly, N. L. Wyers, in his study of male and female homosexual parents that appeared in Social Work, acknowledges that his study "cannot be considered representative" and that "therefore, the findings cannot be generalized beyond the sample itself." 
~ By contrast, R. Green et al. writing in Archives of Sexual Behavior, found that the few experimental studies that included even modestly larger samples (13-30) of boys or girls reared by homosexual parents:
Lack of Random Sampling
Researchers use random sampling to ensure that the study participants are representative of the population being studied (for example, homosexuals or lesbians). Findings from unrepresentative samples have no legitimate generalization to the larger population.
~ L. Lott-Whitehead and C. T. Tully admit the inherent weaknesses in their study of lesbian mothers:
~ N. L. Wyers acknowledges that he did not use random sampling procedures in his study of lesbian and gay spouses, rendering his study "vulnerable to all the problems associated with self-selected research participants." 
~ Golombok et al. write of their study:
Lack of Anonymity of Research Participants
Research procedures guaranteeing complete anonymity are necessary to prevent a source of bias as to who will consent to participate as a research subject, and ensure the truthfulness and candor of their answers.
~ M. B. Harris and P. H. Turner point out in the Journal of Homosexuality:
~ Harris and Turner employed superior research techniques to ensure the complete anonymity of their research subjects. As a result, in contrast to other studies, they reported problems associated with being a homosexual parent that had gone unreported by earlier studies: "Perhaps the anonymity of the present sampling procedure made subjects more willing to acknowledge those problems than those in earlier studies." 
Self-presentation Bias. A lack of random sampling and the absence of controls guaranteeing anonymity allow subjects to present a misleading picture to the researcher that conforms to the subject's attitudes or opinions and suppresses evidence that does not conform to the image he or she desires to present.
~ In their National Lesbian Family Study, N. Gartrell et al. found that eighteen of nineteen studies of homosexual parents used a research procedure that was contaminated by self-presentation bias. Gartrell mentions the methodological problems of one longitudinal study of lesbian families:
~ Harris and Turner admit, with regard to their study:
Evidence from Marmoset Monkeys? Some advocates of homosexual parenting claim to find confirmation of the "normalcy" of homosexual parenting by observing animal behavior. Silverstein and Auerbach, for example, adopt the unusual tactic of appealing to the offspring-raising habits of a soft-furred, tree-dwelling South American monkey to support their contention that homosexual households lead to positive child outcomes: "Marmosets illustrate how, within a particular bioecological context, optimal child outcomes can be achieved with fathers as primary caregivers and limited involvement by mothers. Human examples of this proposition include single fathers ... and families headed by gay fathers." 
The twenty-six species of marmosets live in family groups of up to thirty monkeys. Only the dominant female of the group gives birth, usually to twins. What Silverstein and Auerbach find so impressive about these tiny primates is that, after birth, the males as well as females of the group help carry the baby marmosets, passing them back to the mother for nursing.
It is difficult to grasp the significance Silverstein and Auerbach attach to what they readily admit is an "extreme example" of the supposed "limited parenting involvement by mothers."  The authors contend, "Male marmosets behave like full-time mothers."
It seems there are specific chores that the male marmosets cannot perform. As the authors themselves admit, marmoset mothers perform the essential function of nursing their young, without which the baby marmosets - who must depend upon their mother's milk for the first three months of life - could not survive. In turn, the males of the group fill the vital role of watching the baby marmosets, protecting them from predators, while the nursing mother forages to replenish herself. In short, one could just as well argue, contrary to Silverstein and Auerbach, that the behavior of marmoset monkeys demonstrates that both male and female fulfill separate and important functions in the raising of young.
Psychologist David Blankenhorn, head of the Institute for American Values and author of Fatherless America: Confronting Our Most Urgent Social Problem, criticized such attempts to rely upon behavioral studies of non-human primates to draw conclusions about the character of human families: "I always appreciate critical articles, because they can focus your argument and point out weaknesses. But [Silverstein and Auerbach's] article was unusually silly. Not one thing they said was what I would call a serious insight." 
In their thorough review of homosexual parenting studies, Robert Lerner and Althea K. Nagai found little evidence to support the oft-repeated mantra that homosexual households are "just like" traditional families: "We conclude that the methods used in these studies are so flawed that these studies prove nothing. Therefore, they should not be used in legal cases to make any argument about 'homosexual vs. heterosexual' parenting. Their claims have no basis."

Bozett writes: "Most studies of gay fathers are based on nonrandom small sample sizes, with subjects who are Caucasian, middle- to upper-class, well educated with occupations commensurate with their education, who come mostly from urban centers, and who are relatively accepting of their homosexuality. There is severely limited knowledge of gay fathers who vary from these demographics. Moreover, the validity and reliability of the instruments used in the studies reported are not always addressed."
