I see that new research at Northwestern University indicates that
bisexual men do indeed exist, in contradiction of a 2005 study from the same institution that
appeared to show the opposite.
So far, so duh. The interest from the point of view of this group is that the leader of the earlier study was J. Michael Bailey, author of The Man Who Would Be Queen and arch-proponent of Blanchard's autogynephilia theory. As you will recall, one of the many problems with Bailey's book was the bias in the selection of his subjects (whom he appears to have found mostly in gay bars). It's unsurprising, then, to read that his 2005 study into bisexuality was also vitiated by the fact that subjects "were recruited through advertisements in gay-oriented and alternative publications".
If Bailey's research into bisexuals is being found wanting, and that is being reported in the New York Times, isn't that yet another nail in the coffin of his "research" into autogynephilia, which was flawed in the exact same way?
