the prime minister really is a good example, and it's not what you think.
i don't suspect that justin trudeau would do particularly well on iq tests, but he has inherited a lot of wealth - and a lot of power. but, this is actually counter to design.
his father set that trust fund up so he "wouldn't have to be a lawyer or a politician". dad was trying to give him a way out. but, dad was rich and powerful - and smart. so, what gives?
maybe the correlation isn't there for a better reason than mere inheritance. mmmm?
