Eyes Wide Open: Pupil Dilation and Sexual Orientation

A new study from Gerulf Rieger and Ritch Savin-Williams confirms the relationship between sexual desire and pupil dilation. While this relationship has been known for some time, now it is possible to measure the dilation with precision. In doing so, the authors report significant relationships between self-reported sexual orientation and the way pupils dilate in response to sexual imagery.

Read a summary of the study here, and the open access journal report here.

The authors report that males are more clear in their preferences than women, meaning that whether gay or straight, the dilation of their pupils matched closely their stated preferences. Women were more likely than men to show pupil dilation to both preferred and non-preferred images. Bisexuals also showed dilation to both male and female sexual images.

The results are not perfect in that there is variability of pupil response within sexual orientation groups. These results say nothing about causes of orientation but they do provide more evidence that the attraction component of sexual orientation is mostly involuntary.

The Evangelical Blackout of Sexual Orientation Research, Part 2

Last week, I commented on what I see as an evangelical blackout of sexual orientation research by Christian media and organizations. While I stand by that viewpoint, the situation is actually worse than a blackout. The blackout is selective; some new research is reported. However, the studies reported and the way they are reported seem designed to create a slanted picture.

A case in point. Currently, on the NARTH (National Association for the Research and Therapy of Homosexuality) website, scientific advisory board member, Chris Rosik, reviews a new report from Gartrell, Bos and Goldeberg about lesbian parenting recently published in the Archives of Sexual Behavior. The headline for the review is

New Study: Daughters of Lesbian Parents More Likely to Engage in Same-Sex Behavior and Identify as Bisexual

This is definitely a new study. The blackout is not total, but as I will demonstrate, it is selective. NARTH ignores the hard science involved in the brain scan studies but finds one aspect of a small longitudinal study of lesbian parenting to report. Now that you read the headline, read what Rosik says about how the study can be used.

While this small study is valuable as a starting point for longitudinal research into same-sex parenting, professionals and policy makers should be very wary of making any meaningful conclusions from its findings.  Serious methodological limitations also argue against making sweeping generalizations.  As is the case for the vast majority of studies in this area, the sample size is quite small, constituting only 78 adolescents.  The sample of lesbian parents is self-selected and appears to be different from the general population on important demographics such as socioeconomic status and educational attainment.  Demand characteristics (i.e., external influences such as political goals that might motivate study participants to respond in a particular manner) are not considered or assessed by the study’s authors with respect to the lesbian mothers or their adolescent children.

And then…

Certainly the Gatrell, et al. (2011) study provides some intriguing though entirely non-generalizable findings that are consistent with the hypothesis that non-heterosexual experiences and identities are more common among daughters of lesbian families than those raised in heterosexual families.

First, Rosik reports, via headline, the finding that would be of concern to religious conservatives but then in the article says one cannot make such generalizations. If one cannot generalize beyond the sample, then why report the finding as if one could?

The study also found that no children were abused in lesbian homes. This finding is in contrast to heterosexual families where abuse is reported (26% of teens report physical abuse by a parent or caregiver according to national surveys). Since NARTH is commonly represented in cases against same-sex parenting, and such information is relevant to their membership, why was that fact not a part of the headline?

Another interesting finding in the study was that boys were less likely to have been sexual involved with girls in lesbian families than in straight families. Isn’t that what abstinence educators want to promote?

My point here is that NARTH leaders do keep an eye out for new research, however, their reporting of them is selective. And then when they choose to review a study, their review is selective.

I have established that NARTH is a key source of information for Christian right organizations. When some relevant studies are ignored, and others are selectively reported, it seems clear to me evangelicals are poorly served by the organizations they count on for information.

University of Utah professor: NARTH article “unscientific and irresponsible”

Does engaging in same-sex behavior cause people to become gay? NARTH Scientific Advisory Board member Chris Rosik posed this question in a recent review of a study on risk behavior among gay and bisexual men. The study, led by David Huebner at the University of Utah found that gay and bisexual men who engage in risky sexual behavior may justify subsequent risky behavior as their attitudes change in response to their actions. After reviewing the study, Rosik extended the study findings to the causes of same-sex orientation:

First, if engaging in sexual risk behavior leads to changes in beliefs and attitudes that legitimize such behavior, is it wise to encourage early self-labeling and sexual activity among male adolescents experiencing same-sex attractions? Could participation in early homosexual risk activity such as unprotected (or even protected) anal intercourse lead some adolescent boys down a path of homosexual activity and identity and away from what might have been an eventual heterosexual adjustment?

Rosik proposes that adolescent boys might alter the course of their adult sexual orientation from straight to gay by experimenting with same-sex behavior. However, Rosik’s generalization is improper according to study lead author, David Huebner. In an email, Huebner told me:

Our study examined how adults’ attitudes about condoms and their perceived peer norms about condoms each relate over time to self-reports of condom use during intercourse with casual sexual partners. Condom use is considered a preventive health behavior, and thus, our results might generalize to other preventive behaviors, such as seat belt use, exercise, smoking cessation, or breast cancer screening. Our study does not, in any way, address the development of sexual orientation during adolescence, or the development of normal, healthy sexuality among gay or straight adolescents. Any attempt to generalize our findings to those topics is unscientific and irresponsible.

Huebner’s team researched attitude changes about risk behaviors, not developmental factors in sexual orientation. Furthermore, the findings are not generalizable to the general development of attractions among teens who are attracted to the same sex.

Rosik’s question may seem like harmless speculation to some. However, many on the religious right encourage fear of gay people on the grounds that gays recruit questioning youth who would otherwise be straight. Uganda’s David Bahati justified the draconian Anti-Homosexuality Bill with the claims that gays are recruiting young people. Over the past two years, Bahati has promised to produce evidence of his claims that gays in Uganda systematically recruit kids. To date, he has not produced any such evidence.

Far right pundits in this country raise fears about anti-bullying programs because they might indoctrinate students into homosexuality. Linda Harvey (aka Mission America) yesterday said on her radio show that gays cultivate kids for pedophiles.

Only about 25% of NARTH’s members are clinicians or researchers with professional training or access to the original study. The rest are lay people and culture warriors who look to the NARTH website for accurate information about scientific work. Unfortunately, those readers could easily come away from his review with the perspective that research done by University of Utah researchers supports the recruitment concept of gay development. Although those with a trained or critical eye will catch the improper generalization, I suspect most will not see it. Thus, given the audience of Rosik’s review, I have to agree with Dr. Huebner and say that Rosik’s unqualified speculation is “unscientific and irresponsible.”

First study to refer to ex-gays discredited

In 2000, I presented a paper at the annual conference of the American Psychological Association outlining studies which referred to ex-gays, i.e., people who rejected gay as an identity for religious reasons. That presentation was part of a larger symposium organized by Mark Yarhouse and Doug Haldeman on religious and GLB issues. In 2002, that paper was published in the APA journal Professional Psychology: Research and Practice.* That was the same year I was given the Freud Award at the NARTH conference.
In that paper, I summarized a study by psychiatrist E. Mansell Pattison and his wife Myrna Loy Pattison, titled “‘Ex-gays’: Religiously Mediated Change in Homosexuals.” The Pattisons interviewed 11 men in the Melodyland church in Anaheim, CA who claimed to have changed from gay to straight. One of those men was frequent commenter here Michael Bussee. Another was Gary Cooper, the man who left that ministry and Exodus with Bussee when they both acknowledged that they had not changed their orientation. In other words, two of the 11 had not changed at all.
Today, on the Religion Dispatches website, I describe that study in more detail and interview Michael Bussee about his participation. I encourage you to go read it and comment here or there.
The study continues to be used by NARTH as well as other groups to claim sexual reorientation works. The problems with the study provide more evidence that NARTH’s use of old data (125 year landscape review) is flawed.

The Jones and Yarhouse study: What does it mean?

Let me begin by saying that I endorsed the book, Ex-Gays, A Longitudinal Study of Religiously Mediated Change in Sexual Orientation, by Stanton Jones and Mark Yarhouse which contained the first report of their longitudinal study. Since the publication of the book, Jones and Yarhouse have released results of their final follow up, first in 2009 at the annual convention of the American Psychological Association, and then most recently in the Journal of Sex and Marital Therapy. With the follow up, I believe the study remains an important investigation into the interplay of religion, sexual orientation and personal identity. I give them credit for the perseverance required to explore a topic which is highly controversial and to report their findings in detail.

Since the release of the peer-reviewed article, socially conservative groups have described the study as proof that gays can change orientation. For instance, the American Family Association’s Bryan Fischer, one of the worst offenders, claims that the study proves gays can change and that they weren’t born gay. Also, Citizenlink, an affiliate of Focus on the Family reported:

Of the 98 subjects, more than half were reported as successful; 23 percent reported a complete change in orientation after six years. Also, 20 percent reported giving up the struggle to change.

This claim is misleading. Jones and Yarhouse did not report “complete change in orientation.” Instead they cautioned against misinterpreting their findings by saying

These results do not prove that categorical change in sexual orientation is possible for everyone or anyone, but rather that meaningful shifts along a continuum that constitute real changes appear possible for some. The results do not prove that no one is harmed by the attempt to change, but rather that the attempt does not appear to be harmful on average or inherently harmful. The authors urge caution in projecting success rates from these findings, as they are likely overly optimistic estimates of anticipated success. Further, it was clear that “conversion” to heterosexual adaptation was a complex phenomenon.

Regarding the changes reported by their participants, the authors offer two related explanations. One is that some of the participants changed sexual orientation to some degree and the other is that the participants changed their sexual identity. Sexual identity involves placing more emphasis on behavioral conformity to prohibitions on homosexual behavior as a means of self definition. For the Exodus participants, less temptation to engage in homosexual behavior might be taken as a signal that orientation has changed, thus allowing a different attribution about their sexuality than once believed. The authors raise these two possibilities in the abstract for the most recent paper:

The authors conducted a quasi-experimental longitudinal study spanning 6–7 years examining attempted religiously mediated sexual orientation change from homosexual orientation to heterosexual orientation. An initial sample was formed of 72 men and 26 women who were involved in a variety of Christian ministries, with measures of sexual attraction, infatuation and fantasy, and composite measures of sexual orientation and psychological distress, administered longitudinally. Evidence from the study suggested that change of homosexual orientation appears possible for some and that psychological distress did not increase on average as a result of the involvement in the change process. The authors explore methodological limitations circumscribing generalizability of the findings and alternative explanations of the findings, such as sexual identity change or adjustment.

As I read all of the literature, including my own work, I first want to disagree with the way that Citizenlink characterized the results as “complete change.” That is not at all what Jones and Yarhouse reported. Considering the dichotomy proposed by Jones and Yarhouse — change in orientation or identity – I lean toward their alternative explanation – “sexual identity change or adjustment.”  However, I believe the discussion of what their results mean needs to be broadened beyond those two possibilities. In addition to considering orientation and identity as important constructs, I believe there are other ways to account for the changes Jones and Yarhouse report which are not sufficiently addressed in their published accounts.  First, I want to make some observations about the study which influence my opinions about what the results mean.

First, and most basically, the Jones and Yarhouse study did not examine in any systematic way the efficacy of reparative therapy or any other kind of psychological therapy as a means of altering sexual orientation. The participants in the study were involved in religiously based support groups which primarily had as a goal to reinforce a traditional moral view of sexuality. Clearly, the participants hoped they would change and engaged in various religious interventions to assist that end. However, the study did not assess the role of professional therapy and cannot legitimately be used to say such therapies work.

Second, there were quite a few dropouts six to seven years into the study. While true of all longitudinal studies, the final percentages being reported should also take into account the distinct possibility that many if not most of the drop outs were not successful in their efforts to change. The study began with 98 participants and ended up with 65 who were followed up for six to seven years. Some reported that they were healed of homosexuality and just didn’t want to participate, while others said they were gay and stopped trying to change. I don’t know for sure what the dropouts mean but the fact that so many failed to complete the study needs to be a part of any discussion.

Third, ratings from men and women were combined. Given the low number of people involved I understand why this was done but the practice may inflate the assessments of change for the group. It has become well accepted that the sexuality of women is more fluid than for men. A few women experiencing large shifts could influence the group averages.
