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?
