Some of the 'stupids' people I've met have high IQs.
Eh, depends on how high their IQ is. I can see how someone with an average IQ would think someone with a 150+ could be stupid, or even alien, as their thought processes may seem bizarre and nonsensical. Someone in the 120 - 132 range is still pretty darned normal and rational, personality-wise, and even most of those from 132 - 140.
I think our point is the average intelligence, globally, has been declining, and with the way the world is going, sure seems so.
