One of the things that I failed to develop an appreciation of until quite recently is that I hang out in a really intellectually non-representative crowd. Most of them have multiple degrees and don’t represent an intellectual “average” by any stretch of the imagination, and as such have severely skewed my idea of what “normal” is.
Now by definition the average IQ in the world is 100, and when you start to meet lots of people from the general population, and get a handle on what an average person with IQ 100 is like, they really do seem pretty ordinary.
One thing I had not really given too much thought to was what happens to average IQ people when they get old, but unfortunately this was answered for me when I had the misfortune of sitting down on a bus directly in front of these two ladies in their mid fifties who proceeded to gossip and talk absolute trip for 15 solid minutes of my trip. They used shocking grammar. They used words in the wrong context. They staked their reputations on supporting facts that I knew to be wrong. They professed their ignorance on a raft of current event topics. In short I was apalled by their cluelessness, and was pleased when my bus ride ended, but was left shaken by the realisation that the IQ100 youths you see and meet do not mature into anything better as they age…
