the movie posits the dumb people reproduce faster because they start sooner (i.e. football guy gets cheerleader pregnant when 16, smart girl waits to have a career before getting pregnant) and since getting to reproductive maturity doesn't need special skills it still works out in favor of dumb people (i.e. by the time smart couple has 1 kid dumb couple has >=1 and their descendents have >=1).

Age of reproduction unrelated to smarts. More like hormones.
More like socioeconomic status.

you misinterpreted me, I was referring to what is actually shown in the movie not arguing that sporty people get kids earlier :)
