Vancouver: Academy of Sex Research Controversy

In academic feuds, as in war, there is no telling how far people will go once the shooting starts.

Earlier this month, members of the International Academy of Sex Research, gathering for their annual meeting in Vancouver, informally discussed one of the most contentious and personal social science controversies in recent memory.

The central figure, J. Michael Bailey, a psychologist at Northwestern University, has promoted a theory that his critics think is inaccurate, insulting and potentially damaging to transgender women. In the past few years, several prominent academics who are transgender have made a series of accusations against the psychologist, including that he committed ethics violations. A transgender woman he wrote about has accused him of a sexual impropriety, and Dr. Bailey has become a reviled figure for some in the gay and transgender communities.
