psychology

Kevin J. Hsu is an American psychologist and anti-transgender activist.

Hsu published pathologizing research on “shemales” while working with dissertation advisor J. Michael Bailey at Northwestern University. Hsu is a “gender critical” millennial associated with sexology’s conservative fringe.

Background

Hsu was born in ~1990, grew up in Texas, and attended Northwestern, earning a bachelor’s degree in 2012 and a doctorate in 2019. Hsu did a psychology internship in the Department of Psychiatry at the University of Illinois at Chicago.

His research has focused broadly on understanding sexual orientation using a variety of methods. His clinical work has focused primarily on the assessment and treatment of adults with various psychiatric problems, including anxiety, depression, and substance abuse.

Hsu’s dissertation was titled “Erotic Target Identity Inversions in Male Furries, Adult Baby/Diaper Lovers, and Eunuchs.” Hsu acknowledges advisor J. Michael Bailey; committee members Ray Blanchard, Renee Engeln, and Vijay Mittal; as well as Anne Lawrence, Galen Bodenhausen, Richard Zinbarg, Susan Mineka, Wendi Gardner, Marzena Nowicka, Paul Vasey, John Sylla, Gerulf Rieger, Debra Soh, James Morandini, Heather Hoffmann, and David Moskowitz.

Anti-trans activism

Hsu diagnoses the common attraction to trans women as a made-up disease called “gynandromorphophilia” (GAMP), which Hsu and colleagues describe as “sexual interest in gynandromorphs (GAMs; colloquially, shemales).” Hsu and conservative colleagues are the only people who publish medicalized and pornographic neologisms rather than using scientific and value-neutral terms used by ethical sexologists.

Hsu also diagnoses furries as “autozoophiles,” ageplay enthusiasts as “autopedophiles,” and many trans women as “autogynephiles.” Hsu has published on sex and gender minorities with David I. Miller and Allen Rosenthal. Hsu is one of the few “autogynephilia” activists under age 50.

Ethical controversies

FurFest ban and unauthorized intrusion

Hsu was barred from recruiting participants at Midwest FurFest in December 2013 by the organizers, but attended anyway and tried to talk to several furries about their sexuality.

Violative online survey

A complaint to Northwestern’s Institutional Review Board resulted in Hsu taking down an online survey. Matt Healy attempted to reason with Hsu before contacting Northwestern about a survey that the furry community and ethical furry researchers like Kathleen Gerbasi found concerning. Below is an excerpt from Healy’s complaint:

Kevin’s survey uses several trans slurs

Kevin’s survey uses very poor language. Furry has a large proportion of transgender people and genderqueer people – around one in four based on the data I have seen – people who are vulnerable and sensitive to poorly-chosen language.

Kevin’s survey most egregiously uses the offensive term “shemale”, and also uses terms like “transsexual” in ways that would be considered passe or problematic by people active in the area of queer politics. There are many of such people within furry.

When pressed, Kevin countered that “shemale” is acceptable because it is “used in professional literature.” He cited me two examples: one from [Ray Blanchard and Peter Collins in] 1993, the other from 2011. I reviewed the 2011 (Escoffier) paper, in which “shemale” is only used as a descriptor for a mainstream pornography category. Kevin’s use of this paper as a rationalization strikes me as either disingenuous or willfully misleading. His willingness to defend offensive terminology on specious grounds is consistent based on my conversations with him.

I advised him to use the GLAAD media guidelines as reference for appropriate use of language. Kevin replied: “The GLAAD guidelines are merely guidelines, and they are catered to the media, which we are not. They don’t dictate the discourse in academia, research, or really anything.”

Healy (2015)

Unethical “sissy” survey

Hsu often presents cherry-picked data in an attempt to prove pet ideologies like “autogynephilia.” In 2021, Hsu began promoting a sex survey on non-representative gender diverse forums primarily associated with the sissy community and with “autogynephilia” activists:

Broadly speaking, we are hoping to better understand how gender, sexuality, mental health, personality, attitudes, and relationships intersect with one another in cross-dresser, transfeminine, and other communities (e.g., sissy), and how they might change over time. 

When questioned about the obvious bias in the sampling methodology, Hsu said:

Thank you for raising these concerns. We agree that recruiting from only those subreddits that you mentioned would not capture the wide range of experiences within cross-dressing and transfeminine communities. We do plan to recruit not only from more cross-dresser communities online, but also transfeminine communities as well. We hope to recruit as much of a representative sample of cross-dresser and transfeminine people as possible; if we fall short of that for whatever reason, we can assure that we will be transparent about the limitations of the sample and generalizing of the results.

When questioned another time, Hsu claimed:

We fully intend to post advertisements on and recruit from many other subreddits, forums, and communities to ensure a wide range of participants are included in the study. We have just not had the chance to do that yet

That has not happened as of 2023. The subreddits Hsu contacted are:

  • askAGP
  • MEFetishism
  • TGandSissyRecovery
  • sissyology
  • sissyhypno
  • ForcedFeminization
  • Feminization
  • sissyplace
  • Sissy
  • Sissies
  • forcedfem
  • genderotica
  • gendertransformation
  • girlschool
  • SissyHeaven
  • SissificationProject
  • sissydressing
  • asiansissification

The project’s consent for research states at item 9: “Funds from the Conru Foundation will be used to support this research.”

Andrew Conru is the founder of AdultFriendFinder. Conru’s limited social media presence includes primarily interacting with people associated with the intellectual dark web and with signers of the Harper’s letter, including Dave Rubin, Eric Weinstein, James Lindsay, Tim Pool, and Katie Herzog (quoting Benjamin Boyce).

2025 “autogynephilia” meeting

In 2025, Hsu participated in a meeting with other key “autogynephilia” activists:

Thomas Steensma is a Dutch psychologist who researches gender diverse youth. Steensma’s research and clinical guidelines are frequently cited by anti-transgender extremists who reject affirmative models of care for young people seeking trans health services.

In 2022, Steensma attended a conference organized by anti-trans hate group Society for Evidence-Based Gender Medicine at Tampere University in Finland.

Steensma is also popular with anti-transgender activists for reporting high rates of “desistance” and “detransition.” Steensma co-authored a 2013 longitudinal study tracking 127 adolescents. approximately 37% continued with “gender dysphoria” (which they call “persisters”), while 63% did not (“desisters”) by age 15–16 .

Background

Thomas D. Steensma, works at the Department of Medical Psychology / Center of Expertise on Gender Dysphoria, VU University Medical Center, Amsterdam, The Netherlands. Steensma’s research is focused on people of all ages with gender incongruence. Steensma’s primary projects focus on treatment evaluation, psychosexual development and (gender) identity development (including non-binary gender identities). Steensma studied social and clinical psychology, and is trained as a child and adolescent health psychologist.

“Desistance” research

In a 2013 paper, Steensma and co-authors stated that 63% of adolescents included in the study “desisted”:

Between 2000 and 2008, 225 children (144 boys, 81 girls) were consecutively referred to the clinic. From
this sample, 127 adolescents were selected who were 15 years of age or older during the 4-year period of follow-up between 2008 and 2012. Of these adolescents, 47 adolescents (37%, 23 boys, 24 girls) were identified as persisters.

Because this is one of the highest “desistance” rates ever reported, anti-trans activists frequently cite this study. Critics have discussed methodological issues, particularly how to count people lost to follow-up / non-responders.

Press coverage

In 2018 KQED reported:

In Amsterdam, clinicians at the Center of Expertise on Gender Dysphoria are much more cautious about recommending social transitions because of the statistics on desistance. Thomas Steensma, a researcher and clinician at the center, acknowledges  these studies probably included some kids who would not be diagnosed with gender dysphoria today. Nevertheless, despite the problems with the way they classified children, “the only evidence I have from studies and reports in the literature  … is that not all transgender children will persist in their transgender identity,” Steensma said. ‘Why are we asking a child to conform to something that is not them because society hasn’t done its learning yet?’

In 2013, Steensma co-authored an oft-cited study that examined 127 adolescents, all of whom had displayed various levels of gender dysphoria as children. The researchers found that 80 of the children had desisted by the ages of 15 and 16. That works out to 63 percent of kids who basically stopped being transgender — a lower rate than in previous studies, but still a majority.

Some clinicians criticize this study, however, on methodological grounds, because the researchers defined anyone who did not return to their clinic as desisting. Fifty-two of the children classified as desistors or their parents did send back questionnaires showing the subjects’ present lack of gender dysphoria. But 28 neither responded nor could be tracked down.

Coverage in anti-trans media

In 2020, Steensma co-authored research and overviews on how negative media coverage affects transgender youth and their access to care.

Gert Comfrey is an American therapist who identifies as nonbinary and queer. Comfrey specializes in marriage and family therapy issues that affect sex and gender minorities.

Background

Comfrey was born in November 1985, grew up in Central Pennsylvania, and was known by another name prior to adulthood.

Comfrey earned a bachelor’s degree from Elizabethtown College in 2008, then earned two master’s degrees; one from Vanderbilt Divinity School in 2010, and one from Trevecca Nazarene University in 2015.

In 2019 Comfrey was a panelist at the LGBT+ College Conference held at Middle Tennessee State University.

Comfrey opened a marriage and family therapy practice in Nashville, Tennessee in 2019:

I have extensive experience working with transgender clients and clients wanting to explore gender identity, along with letter-writing for gender affirming surgeries. I am also a trained Circle facilitator and have offered trainings to healthcare professionals, counseling interns, and students regarding best practices when working with queer clients.

Comfrey is known to many from an appearance in the 2022 anti-trans propaganda piece What Is a Woman? In it, Comfrey earnestly explains that sex and gender are more complicated than binaries, prompting interviewer Matt Walsh to ask about personal gender identity, “So how do I know?” Comfrey responds, “That question, when it’s asked with a lot of curiosity, that’s the beginning of a lot of people’s gender identity development journey.” Many people who enjoy Walsh’s incurious bad-faith tactics found the exchange entertaining.

Stella O’Malley is a conservative Irish therapist and anti-transgender extremist. O’Malley is a global ringleader in the modern ex-transgender and gender critical movements and a major supporter of anti-transgender efforts worldwide.

O’Malley founded SPLC-designated anti-trans hate group Genspect. O’Malley frequently collaborates with American clinician Sasha Ayad to uplift other conservative and anti-transgender voices.

They promote

Do not under any circumstances go to Stella O’Malley for any counseling, trans or otherwise. If you are a minor forced to see O’Malley, do everything in your power to end the sessions and find supportive local resources instead.

Background

O’Malley was born on November 16, 1973. O’Malley grew up with three siblings in the Dublin area in a household where at least one parent was alcoholic.

O’Malley and spouse Henry Thompson, a construction contractor, live in Birr, County Offaly with their two children RĂłisĂ­n Thompson (born November 9, 2007) and Muiris Thompson (born August 5, 2009). O’Malley’s self-described parenting style is “impatient, moody and cranky” with “a very low threshold for ordinary whining.”

O’Malley authored Cotton Wool Kids (2015) Bully-Proof Kids (2017), and Fragile (2019).

Anti-trans activism

O’Malley was host of the 2018 propaganda piece Trans Kids: It’s Time To Talk. It features conservative and anti-trans activists, including James Caspian, Heather Brunskell-Evans, Venice Allan, Miranda Yardley, and people from the ex-trans movement

O’Malley is connected to a number of anti-trans organizations, most of which are just part of a web farm with reciprocal links to make O’Malley’s allies and their fringe ideologies seem more widespread and influential than they are.

These fringe front groups include:

In 2023 O’Malley co-authored the anti-trans book When Kids Say They’re Trans: A Guide for Parents with Sasha Ayad and Lisa Marchiano.

In 2024, when Texas politician Shawn Thierry lost the Democratic primary and joined Genspect as director of political strategy in the US. An article noting the announcement said:

Genspect has also been accused by medical experts and organizations of relying on junk science to support their stance. O’Malley, for instance, has falsely claimed that there are links between peer pressure, pornography and gender dysphoria. Genspect has also partnered with groups such as the right-wing Alliance Defending Freedom, and argues that no one under the age of 25 should be allowed to transition because their brains “haven’t yet fully matured.”

Gender: A Wider Lens

Ayad and O’Malley hosted the podcast Gender: A Wider Lens. The guests include many global leaders in modern conservative and anti-transgender activism.

In 2025, O’Malley started the podcast Beyond Gender, co-hosting with anti-trans extremist Mia Hughes and anti-trans psychologist Bret Alderman.

In 2025, O’Malley criticized how the “the gender-critical woke” have been attacking people who share O’Malley’s politics:

It is deeply sad to consider how many gender-critical people have been censured or censored by the gender-critical woke. The list is long, and I’ve probably forgotten many. But among them are: Janice Turner, Debbie Hayton, Fionne Orlander, Miranda Yardley, Kristina Harrison, Buck Angel, Claire Graham, Jack Appleby, Graham Linehan, James Esses, Sarah Phillimore, Rosie Duffield, Claire Fox, Helen Pluckrose, Benjamin Boyce, Mike Bailey, James Cantor, Ken Zucker, Ray Blanchard, Billboard Chris, Genspect, LGB Alliance, Jenny Watson, Kathleen Stock, Julie Bindel, Suzanna Moore, Hadley Freeman, Sarah Ditum, Maya Forstater, Helen Joyce, Women’s Place UK, Judith Green, Labour Women’s Declaration, Fair Play for Women, Aaron Tyrrell, Aaron Kimberly, GD Alliance, Corinna Cohn, Shannon Thrace, Eva Kurilova, Frank Furedi, Alasdair Gunn, James Lindsay, Jordan Peterson, Michael Shellenberger, Mia Hughes, Abigail Shrier, Colin Wright, Christina Buttons, Andrew Doyle, and Jane Clare Jones.

Randi Ettner is an American psychologist and author known for affirming work with transgender and gender diverse people.

Background

Randi Joy (Cahan) Ettner was born in 1952 in Lincolnwood, Illinois. Ettner’s aunt was noted sexologist Leah Cahan Schaefer. Ettner earned a bachelor’s degree from Indiana University, followed by a master’s degree from Roosevelt University.

Ettner began working with transgender people in 1977 at Cook County Hospital in Chicago, Illinois. Ettner received a doctorate in psychology at Northwestern University, with a dissertation on childbirth. Ettner had additional training at Moray House School of Education in Scotland.

Ettner is founder of New Health Foundation Worldwide and works with spouse Frederic M. “Fred” Ettner, a physician.

Ettner referred transgender patients to surgeon Eugene Schrang until Schrang’s retirement. Ettner is a member of the American Psychological Association and is a Fellow, Diplomate, and served on the Board of Directors from 2001 to 2005 for the World Professional Association for Transgender Health.

Ettner has helped pass anti-discrimination laws, provided testimony on behalf of trans people seeking workplace rights, and works to secure appropriate treatment for prisoners. Ettner has also been a critic of psychologist J. Michael Bailey‘s 2003 book The Man Who Would Be Queen. Bailey claims the book was initially motivated by “gross inaccuracies in Ettner’s account of transsexualism.” Ettner works to improve understanding of trans issues, and has spoken out against attitudes used to justify violence against trans people.

Below is a clip from a 2006 interview I did with Dr. Ettner on coming out.

Scott Barry Kaufman is an American psychologist who frequently platforms anti-transgender activists and people associated with the intellectual dark web, a gateway to the far right. Kaufman also platforms academics who promote evolutionary psychology, an ideology frequently opposed to value-neutral scientific conceptualizations of trans and gender diverse people.

Ever since a graduate thesis on the subject, Kaufman been invested in misusing science to maintain and justify sex categories and sex segregation, in the way that race science has been misused to maintain and justify racial categories and segregation. Academic sex segregationists have staked their careers and legacies on defending the few remaining sex-segregated institutions.

Kaufman objects to being listed on this site, saying, “I try every day to do good in the world and have never done anything damaging to trans people.”

Background

Scott Barry Kaufman was born June 3, 1979 to Barbara Alpert (born ~1956), a professor of medicine, and Michael Stephen Kaufman (born ~1954), a lawyer specializing in mergers and acquisitions. Both parents went to Harvard and were from families of high social standing.

Kaufman earned a bachelor’s degree in psychology from Carnegie Mellon University, followed by a master’s degree from Cambridge. Kaufman’s 2007 master’s thesis was titled “Sex differences in mental rotation and spatial visualization ability: Can they be accounted for by differences in working memory capacity?” Kaufman then earned a doctorate in cognitive psychology from Yale, with a research focus on intelligence.

After personally experiencing challenges in early formal education, much of Kaufman’s work involves helping children realize their full potential. Kaufman has authored, co-authored, edited, and contributed to several books for a lay audience:

  • The Psychology of Creative Writing (2009)
  • Ungifted: Intelligence Redefined (2013)
  • Mating Intelligence Unleashed: The Role of the Mind in Sex, Dating, and Love (2013)
  • The Complexity of Greatness: Beyond Talent or Practice (2013)
  • The Philosophy of Creativity: New Essays (2014)
  • Wired to Create: Unraveling the Mysteries of the Creative Mind (2015)
  • Twice Exceptional: Supporting and Educating Bright and Creative Students with Learning Difficulties (2018)
  • Transcend: The New Science of Self-Actualization (2020)
  • Learned Hopefulness: The Power of Positivity to Overcome Depression (2020)
  • Choose Growth: A Workbook for Transcending Trauma, Fear, and Self-Doubt (2022)

The Psychology Podcast

Kaufman hosts The Psychology Podcast and has consistently platformed gender-critical and anti-transgender guests, including:

Guests involved in the intellectual dark web, “viewpoint diversity,” “academic freedom,” and “anti-woke” movements include:

In December 2022, Kaufman outlined agreement with anti-trans activist Jesse Singal about disagreements:

My friend @jessesingal convinced me that the following is probably true: “People look at someone’s behavior, and then, based on how much it outrages them, they decide whether to attribute it to personal shortcomings (their fault) or mental illness (not their fault).”

In 2022, Kaufman expressed an interest in a “debate” on trans issues and trans rights.

Who would you like to see have a respectful, healthy debate about trans issues and trans rights? I’d love some suggestions of reputable evidence-based experts who have differing viewpoints. I will moderate this on @psychpodcast. Thanks!

Kaufman (2022)

When I asked Kaufman to provide more details on which rights for trans people should be debated, Kaufman said, “I’m afraid I don’t have the time to respond to your questions. I am extremely busy.”

If a podcaster consistently platformed antisemitic guests then suddenly wanted to have a “respectful healthy debate on Jewish issues and Jewish rights,” Kaufman would probably have a few questions. It’s also interesting that none of Kaufman’s gender critical guests appeared with someone who had opposing views.

Psychology is one of the key ways the state exerts social control on trans people. Academic exploitation of sex and gender minorities is well documented. People like Kaufman perpetuate these oppressive systems, probably unintentionally. It’s what biologist Julia Serano calls “trans unaware” and “trans suspicious” thinking.

In 2023, Kaufman released a series of podcast episodes on sex and gender. The episode titles reflect Kaufman’s anti-trans bias. Episodes Kaufman calls “science” are by gender critical people who have similar conservative views.

Kaufman chose not to use science to describe the episode with noted biologist/geneticist Anne Fausto-Sterling, even though Fausto-Sterling is by far the most notable and accomplished scientist Kaufman interviewed. That’s because Fausto-Sterling’s views are informed by the latest in scientific understanding of sex and gender and not Kaufman’s own biased views.

Episode list

  • “What we get wrong about transgender people” with Aaron Rabinowitz and Callie Wright
    • a decent introductory discussion about minutiae that ignores larger systemic issues
  • “The Science of Testosterone” with activist Carole Hooven
    • covers many of Hooven’s areas of activism
    • sex-segregated sports
    • disease models of gender identity and expression
    • maintaining a sex binary “the opposite sex”
    • fearmongering about “irreversible” puberty blockers
    • desistance” narratives: most gender diverse youth will turn out gay without access to healthcare
    • gatekeeping narratives: social transition leads to medical transition (Kaufman quipped “pronouns are a gateway drug”)
    • ROGD” talking points: “lifetime of surgery and drugs and complications”
    • Hooven praises federal gatekeeping of reproductive healthcare: “United States is behind Europe”
  • “The Scientific Realities of Biological Sex” with gender critical psychologist Debra Soh, evolutionary psychologist Marco Del Giudice, and conservative trans porn star Buck Angel
  • “Gender/Sex and the Body” with biologist/geneticist Anne Fausto-Sterling
    • This is the only one worth listening to

Kaufman says this quote exemplifies the psychologist’s views on trans people:

You tweeted something this morning that caught me. You were talking about a study that was showing how hard it must be to be a transgender person because you walk through the world and the entire world has evolved to really only see two gender identities in this. So it’s like a millisecond in our evolutionary perspective. We just don’t quite have the ability to see them they way they see themselves.

Kenneth Zucker is an American-Canadian psychologist and anti-transgender extremist.

Zucker’s ideology has caused profound harm to sex and gender minorities over a long career. Zucker has created several disease models to describe these minorities and has promoted many more sex and gender “disorders” as editor of The Archives of Sexual Behavior.

Zucker developed a non-affirming model of care for gender diverse youth that has been described as “child abuse.” Zucker was fired by employer CAMH in 2015. Zucker’s clinic was shut down, and non-affirming models of care have been outlawed in many jurisdictions.

After I was defamed in Archives of Sexual Behavior in 2007, I personally began working in earnest to get Zucker fired. Below is the last major exposé I wrote prior to that firing:

Sexology’s war on transgender children

Background

Kenneth J. “Ken” Zucker was born on December 29, 1950 to Eugene M. Zucker (1922–1997) and Sara Miller Zucker (1924–2020). Zucker has one sibling, Barbara Ann Zucker-Romanoff aka Barbra Zucker (born 1957). The family lived in Skokie, Illinois. Zucker married Rochelle Fine, also from Niles Township. Their child Simone Zucker is a Toronto-based filmmaker, and their child Josh aka “Concentration Camp” is guitarist in Toronto band Fucked Up.

Zucker attended Southern Illinois University during the Vietnam War and was one of the key campus leaders in the anti-war protest movement there, staging mock trials and declaring people war criminals in absentia (Lagow 1977). Zucker earned a bachelor’s degree there, then a master’s degree at Roosevelt University in 1975.

Zucker headed to Canada eventually just to be safe. Zucker earned a doctorate from University of Toronto in 1982. 

Zucker’s frequent collaborator Richard Green had the same impulse for self-preservation: “I left Los Angeles in 1964 to avoid the Vietnam War by going to NIMH [National Institutes of Mental Health]” (Green 2004). In 2001 Green handed over editorial control of Archives of Sexual Behavior to Zucker, to continue pushing their toxic ideology about sex and gender minorities.

Physical attractiveness of children “research” (1993–1996)

Zucker was a psychologist at the Clarke Institute (aka “Jurassic Clarke”) in Toronto. Zucker is infamous for forcing gender-diverse children into reparative therapy to conform to expectations for gendered behavior in children. Zucker considers a gender transition a “bad outcome.”

Zucker had access to hundreds of children through the Clarke and took topless photos of all children brought to the clinic. In one particularly troubling “study,” Zucker wanted to see how “physically attractive” these children’s faces and upper torsos were. Adults were shown images of children in Zucker’s care and asked to rate their attractiveness.

Zucker’s conclusion: “Boys with gender identity disorder were judged to be more attractive than were the clinical control boys.”

Zucker repeated the “research” with the remaining children a few years later, concluding the “Girls with gender identity disorder had significantly less attractive ratings than the normal control girls for the traits attractive, beautiful, and pretty.”

Both studies were published in Archives of Sexual Behavior, the journal Zucker now edits.

Other harmful views

Zucker is a darling of the ex-gay movement because of decades of attempts in “curing” gender-diverse children. Zucker was frequently cited by ex-gay groups like NARTH (National Association for Research & Therapy of Homosexuals) and Leadership U.

As the rest of the world begins to understand and accept gender diversity as a trait and not a disease, Zucker has been increasingly cast as the old-school holdout in press coverage. As noted in the New York Times:

Dr. Kenneth Zucker, a psychologist and head of the gender-identity service at the Center for Addiction and Mental Health in Toronto, disagrees with the “free to be” approach with young children and cross-dressing in public. Over the past 30 years, Dr. Zucker has treated about 500 preadolescent gender-variant children. In his studies, 80 percent grow out of the behavior, but 15 percent to 20 percent continue to be distressed about their gender and may ultimately change their sex.

Dr. Zucker tries to “help these kids be more content in their biological gender” until they are older and can determine their sexual identity — accomplished, he said, by encouraging same-sex friendships and activities like board games that move beyond strict gender roles.

Brown (2006)

Anti-trans activist J. Michael Bailey summarized Zucker’s ideas in the defamatory book The Man Who Would Be Queen:

Zucker thinks that an important goal of treatment is to help the children accept their birth sex and to avoid becoming transsexual. His experience has convinced him that if a boy with GID becomes an adolescent with GID, the chances that he will become an adult with GID and seek a sex change are much higher. And he thinks that the kind of therapy he practices helps reduce this risk. Zucker emphasizes a three-pronged treatment approach for boys with GID. First, he thinks that family dynamics play a large role in childhood GID—not necessarily in the origins of cross-gendered behavior, but in their persistence. It is the disordered and chaotic family, according to Zucker, that can’t get its act together to present a consistent and sensible reaction to the child, which would be something like the following: “We love you, but you are a boy, not a girl. Wishing to be a girl will only make you unhappy in the long run, and pretending to be a girl will only make your life around others harder.” So the first prong of Zucker’s approach is family therapy. Whatever conflicts or issues that parents have that prevent them from uniting to help their child must be addressed.

The second prong is therapy for the boy, to help him adjust to the idea that he cannot become a girl, and to help teach him how to minimize social ostracism. Zucker does not teach boys how to walk in a manly fashion, but he does give them feedback about the likely consequences of taking a doll to school.

The third prong is key. Zucker says simply: “The Barbies have to go.” He has nothing against Barbie dolls, of course. He means something more general. Feminine toys and accoutrements—including Barbie dolls, girls’ shoes, dresses, purses, and princess gowns—are no longer to be tolerated at home, much less bought for the child. Zucker believes that toleration and encouragement of feminine play and dress prevents the child from accepting his maleness. Common sense says that a boy who wants to play with dolls so much that he is willing to risk his father’s wrath and his peers’ scorn is unlikely to change his behavior due to inconsistent feedback, sometimes forbidding, sometimes tolerating, and sometimes even encouraging it. Inconsistent parenting like this is ineffective in stamping out any kind of unwanted behavior.

Failure to intervene increases the chances of transsexualism in adulthood, which Zucker considers a bad outcome. … Why put boys at risk for this when they can become gay men happy to be men?

Bailey (2003), pp. 31-32

Zucker blames poor family dynamics and maternal psychopathology for gender-nonconforming behavior. Zucker claims this phenomenon is more likely in non-white children with lower IQs. As J. Michael Bailey noted:

Ken Zucker, whom we met in Chapter 2, has tried to predict which boys with gender identity disorder (GID) would still have the disorder when they become adolescents. Adolescents with GID are much rarer and presumably much closer to being transsexual. Zucker found several predictors of adolescent GID: lower IQ, lower social class, immigrant status, non-intact family, and childhood behavior problems unrelated to gender identity disorder.

Bailey (2003) pp. 178-179.

Zucker’s alleged “desistance” rate hides the fact that many children brought to Zucker’s clinic are hardly success stories in terms of quality of life outcomes:

Yet Zucker’s approach has its own disturbing elements. It’s easy to imagine that his methods—steering parents toward removing pink crayons from the box, extolling a patriarchy no one believes in—could instill in some children a sense of shame and a double life. A 2008 study of 25 girls who had been seen in Zucker’s clinic showed positive results; 22 were no longer gender-dysphoric, meaning they were comfortable living as girls. But that doesn’t mean they were happy. I spoke to the mother of one Zucker patient in her late 20s, who said her daughter was repulsed by the thought of a sex change but was still suffering—she’d become an alcoholic, and was cutting herself. “I’d be surprised if she outlived me,” her mother said.

Rosin (2008)

Paul L. Vasey is a Canadian psychologist who promotes harmful ideas about sex and gender minorities, especially transgender and gender diverse people and those who love us:

Vasey is one of the last of the old-school Canadian evolutionary psychologists allied with fired sexologist Kenneth Zucker. Vasey’s coauthors and associates are part of an activist minority in sexology, most of whom are cisgender and born before 1970. Vasey holds some supportive views, but they are all colored by an embrace of unscientific and pseudoscientific terminology created by Vasey’s friends. Science and its operational definitions must be value-neutral in order to produce bias-free scientific results.

Background

Paul L. Vasey (born January 30, 1966 in Toronto, Ontario, Canada) earned a bachelor’s degree from University of Alberta in Edmonton in 1989, then earned a master’s degree from Simon Fraser University in 1991. Vasey earned a doctorate from UniversitĂ© de MontrĂ©al in 1997. Vasey’s dissertation was on Japanese macaques under advisor Bernard Chapais. Vasey then did postdoctoral work at UniversitĂ© de MontrĂ©al, Concordia University (MontrĂ©al) and York University.

Vasey was hired as an Assistant Professor in the Department of Psychology at the University of Lethbridge in 2000. While preparing to teach a course on sex and gender, Vasey became interested in Samoan fa’afafine culture. Vasey describes them as “feminine, same-sex attracted males that are recognized as a non-binary gender.” Vasey’s partner is Vaitulia Alatina Ioelu, a self-identified Samoan fa’afafine.

Vasey is a close collaborator with Anne Lawrence. Vasey gave Lawrence a job and is acknowledged in Lawrence’s publications for the International Academy of Sex Research.

Archival material

Vasey co-authored a paper with two Concordia University psychologists on childhood gender diversity.

Bartlett NH, Vasey PL, Bukowski WM (2000) Is gender identity disorder in children a mental disorder? Sex Roles, 43 11/12, 753-785. Article ID: 299688 

Empirical studies were evaluated to determine whether Gender Identity Disorder (GID) in children meets the Diagnostic and Statistical Manual of Mental Disorders-4th Edition ( DSM-IV, American Psychiatric Association, 1994) definitional criteria of mental disorder. Specifically, we examined whether GID in children is associated with (a) present distress; (b) present disability; (c) a significantly increased risk of suffering death, pain, disability, or an important loss of freedom; and if (d) GID represents dysfunction in the individual or is simply deviant behavior or a conflict between the individual and society. The evaluation indicates that children who experience a sense of inappropriateness in the culturally prescribed gender role of their sex but do not experience discomfort with their biological sex should not be considered to have GID. Because of flaws in the DSM-IV definition of mental disorder, and limitations of the current research base, there is insufficient evidence to make any conclusive statement regarding children who experience discomfort with their biological sex. The concluding recommendation is that, given current knowledge, the diagnostic category of GID in children in its current form should not appear in future editions of the DSM .

Below is a course description for Vasey’s Sex & Gender Diversity (Psychology 3850) Spring 2003

In this course, we will explore issues related to sex and gender diversity. To this end, we will critically examine the binary construction of sex and gender through such topics as intersexuality, gender identity disorder, and “third” sexes and genders in non-Western societies. A central part of this theoretical examination involves discussing the real-world consequences individuals face for deliberately or inadvertently transgress dichotomous sex and gender boundaries.

Below is a course description for Vasey’s Science & Sexuality (Psychology 4000NA) Spring 2004

In this seminar, we will explore the controversy surrounding the publication of J. Michael Bailey’s book, “ The Man Who Would be Queen .”  Bailey’s book deals with the subject of male femininity through such topics as gender identity disorder in childhood, homosexuality, transvestitism, and male-to-female (MtF) transsexualism. Although reaction from the gay community has been largely unremarkable, the book has ignited a storm of protest in the MtF transexual community. In particular, some transsexual women dispute Bailey’s claim (based on the work by Toronto sexologist, Ray Blanchard) that there are two distinct sub-categories of MtF transsexuals: homosexual versus autogynephilic.  

We will familiarize ourselves with the controversy by reading The Man Who Would be Queen and the contents of two websites managed by transsexual women, [] & Lynn Conway, who are spearheading the response to Bailey. We will then critically investigate the evidence for each point of view. We will begin by examining the claim that two specific types of MtF transsexuals exist primarily by reading scientific articles written by Ray Blanchard and Anne Lawrence.  Anne Lawrence, a Seattle-based doctor who specializes in sexual medicine, is a self-identified autogynephilic transsexual woman and a supporter of Blanchard’s work.  We will then read “ True Selves: Understanding Transsexualism ” by Mildred L. Brown & Chloe Ann Rounsley and “ Mom, I Need to Be a Girl ,” by Just Evelyn,  which [], Lynn Conway and several transsexual advocacy groups highly recommend as a more accurate depiction of the MtF transsexual experience and an alternative to the Bailey/Blanchard model.  Through the semester we will weigh the evidence for, and against, Blanchard’s dichotomous conceptualization of transsexuality.  In addition to the readings, documentary films on homosexuality, cross-dressing and transsexualism will be screened during the last hour of some seminar classes.
