For some time I’ve noticed that bisexual men in my surveys tend to score higher on measures of gender issues than other men. Initially, the explanation for this was easy: studies have had trouble finding truly bisexual men (see e.g. here or here), so there’s probably some third factor that makes them think they are bi without truly being bi. One possible factor is autogynephilia, and the bisexual men in my surveys are indeed often autogynephilic. Case closed?

… almost. I don’t have many bi men in my surveys, and most of them are autogynephilic, so it’s not clear whether the non-autogynephilic bi men also score higher. However, today I combined the data from a number of surveys (Broader Gender Survey, Thorough Genderbending Survey, Gender and Psychology Survey, Amazon Mechanical Turk Gender Survey, Sexuality and Attitudes to Gender Survey, Survey on Gender and Valued Experiences) to get a total of 40 non-AGP bi men, along with 469 non-AGP straight men, 761 AGP straight men, 157 AGP bi men, 71 AGP gay men and 64 non-AGP gay men. The different surveys used different ways of assessing gender issues, so I standardized them by dividing by the standard deviation and subtracting the average value from the non-AGP straight men. Here’s the results for the surveys separately:

Results from different surveys wrt. gender issues in different groups of men. The x-axis shows the difference in average gender issues between the group and straight non-AGP men. The y-axis shows the significance of the survey, roughly 1/√N, where N is the number of people in the group. Closer to zero in the y means more significant.

This is a bit messy, so I’ve also made a separate chart with the average gender issues across the surveys:

Weighted average of last diagram, with the weights equal to the number of men in the groups.

To me, those results suggest that bisexual men don’t simply score higher on gender issues due to AGP, but also due to some other factor. Unless… maybe some of these men are AGP, but don’t realize it? Though in that case, it’s hard to explain why AGP bi men score higher than other AGP men. This might be attributed to the fact that interpersonal autogynephilia is associated with gender dysphoria beyond the other forms of autogynephilia, but this should also imply that AGP gay men score higher.

I don’t know.
