EatsBrainsAndLeaves - "instead it asked people who was most intelligent - their mother or father. About two thirds of people said their father. Of course statistically, it should be about fifty fifty. So about fifty per cent saying their father is more intelligent and fifty per cent their mother."
I might just be a bit crap at statistics, but I really don't understand why it should be 50%. Unless everyone gets partnered up and has kids. But lots of people are not parents.
I not convinced that people automatically assume their father is more intelligent than their mother, isn't it just as likely that he actually IS more intelligent? There might be a lot of super intelligent single women and idiot single men out there.
People consider intelligence when they choose a partner, even if they don't do it consciously. (I'm single so I don't necessarily know what I'm talking about here). Isn't it unlikely that exactly half the population would choose someone more intelligent than them and the other half someone less intelligent?
Or did you mean "should" as in, the world "should" be this way - but it is, in fact, not?
