Take, for example, Shkreli. Major dick but pretty clever by the looks of it. Now found guilty of fraud.
Bill Gates was a major dick. Made tonnes of money but yet reviled and found himself in the dock because of it.
Steve Jobs. Really intelligent but still booted out of Apple due to sheer dickheadery.
Now they all found major success, hence why EQ means fuck all. It seems they, or some, found out they had to do some serious thinking. Bill Gates is arguably the most redemptive.
Imagine you had average intelligence or just above and you were a major dick? People like that get asked to leave more often than not.
