I wish I still had the link, but I recall reading an article where the author showed that by actual measurement IQs go down on average when people go to college. In other words most people get dumber in college, not smarter. This appears to be true to me by personal observation. My friend’s kids coming out of college believe the stupidest shyt imaginable and have little capacity for critical thinking.
The old axiom “Educated beyond the capacity to think.”comes to mind.
