I should watch that movie, could be amusing. However I'm not sure I understand what you mean. I don't think the study reached a conclusion as to how many children someone might have, merely that the sperm quality was higher/lower.

The movie gives the view that dumber people get more kids compared to smart people. So the world will, after a point, contain more dumb people than smart people because they simply breed more.

Unless there are other compensating factors, like dumb people having higher mortality rates?

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 :)

Or going on the TV show "Oww my balls"
