I'm not aware of any study which suggests that IQ is bimodally
distributed in men.
It should be pointed out that there is a lot of doubt about there even
being a "general" intelligence, as such (a general-purpose calculuating
machine model of the brain). Men tend to score lower than women in
verbal intelligence tests, for instance, while men tend to score higher
than women in spatial and quantitative tests.
