Paul L. Vasey is a Canadian evolutionary 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 sociobiologists allied with fired sexologist Kenneth Zucker and the anti-trans journal Archives of Sexual Behavior. Vasey promotes medicalized disease models of attraction to transgender people, including “gynandromorphophilia” as well as the controversial diagnosis “autogynephilia.”
Vasey has collaborated with other anti-trans activists, including J. Michael Bailey, Ray Blanchard, Marc Breedlove, Alex Byrne, Alice Dreger, Kevin Hsu, Martin Lalumière, Anne Lawrence, James Morandini, Scott Semenyna, Doug VanderLaan, and Eric Vilain. Vasey’s co-authors and associates are part of an activist minority in sexology, most of whom are cisgender and born before 1970. Vasey holds some trans-supportive views, including criticisms of Zucker’s controversial disease “gender identity disorder in children,” 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 was born on January 30, 1966 in Toronto, Ontario, Canada. Vasey 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 Université de Montréal in 1997. Vasey’s dissertation was on Japanese macaques under advisor Bernard Chapais. Vasey then did postdoctoral work at Université de Montréal, Concordia University (Montréal) 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.
Course material (2003–2004)
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. Required Readings:
- (1) Kessler, S. (1997). Lessons From the Intersexed. Rutgers University Press: New Brunswick, New Jersey.
- (2) Course-pack containing Chapter #1, “Behavior,” from: Burke, P. (1996). Gender Shock: Exploding the Myths of Male and Female.Anchor Books, Doubleday: New York.
- (3) Additional short readings drawn mainly from popular magazine will be distributed in class.
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, [Andrea James name removed] & 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 [Andrea James name removed], 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. Required Readings :
- (1) Bailey, J.M. (2003). The Man Who Would Be Queen: The Science and Psychology of Gender-Bending and Transsexualism . NY: Joseph Henry Press.
- (2) Additional required readings will be placed on reserve in the library.
