Earlier this summer, scientists at Northwestern University found that bisexual men exist.
Duh! Or would that be: Duh?
As the Los Angeles Times reported in this recent examination of "duh science," some research seems so painfully obvious it makes you wonder why scientists even bothered to go through with it. (In this case, even one of the Northwestern scientists admitted to the New York Times that the research might make people go "Well, duh!" at first glance.)
But a closer look often shows that even when conclusions seem self-evident, there can be good reasons to delve into duh. The bisexuality research, which was published in the journal Biological Psychology, might be such a case, because it challenges a widely held notion -- not to mention a controversial paper, also out of Northwestern -- that bisexual men, at least according to one definition, don't exist at all.
In the earlier Northwestern study, which was conducted in 2005, researchers recruited self-described bisexual men and measured their genital arousal as they were shown erotic movies showing only men, or erotic movies showing only women. The scientists, who also observed homosexual and heterosexual men as part of the study, discovered that most of the bisexual men were aroused by looking at only one sex or only the other (usually men).
