[[When I was younger the idea was that people with higher IQ’s should go to college, and college was intellectually challenging. ]]
Yep- I think that sums it up and explains why the iq for college students tends to be higher-
Like Clint Eastwood said “a man’s got to know his limitations “
Most folks tended to think that a life of hard blue collar work was in store for,them fate-wise if they weren’t smart, so off to work at a young age, while the smarter folks thought that higher education would give them advantages in life, so off to further schooling they went.
I think that might explain the difference in average iqs
Today however, hardly any of the kids want to go off to work, and with all the low income grants and such go to higher education, so the average is drops. Back I. The day I don’t think low income grants were as available.
Funny how that worked out. Your plumber sporting a butt crack has steady work and makes much more an hour than many college educated.
