A new study published in this month's Journal of Personality and Social Psychology states that gaydar may be dependent on how we walk. I've got to wonder here. Many gay men have friends and family with no clue they're gay and I question whether a study like this doesn't assume that all gay men exhibit the same walking behavior (perhaps what we might call swishy even if only slight) when, in fact, they don't. Some may not ever exhibit it and others may learn to suppress it early on. I also am concerned about any study that relies on self-assessment of behvaior to rely on the validity of results. It appears that they relied upon the subjects themselves to indicate whether they were gay or not. Might not out gay men feel freer to be swishy if they were so inclined? Might not closeted gay men feel the need to conceal any physical traits that would identify them as gay? Again, do all gay men exhibit this tendency? Apparently not if only eight subjects were used yet sexual orientation could be determined 60% of the time. There's an interesting graphic on that linked page showing the locomotion of what the study purports to be gay men versus straights of both sexes and lesbians however it's way too short and small to examine closely.
