Honestly, this is why most collections of human beings don’t stay together long; including marriages. I used to call this the “David Lee Roth Crowd IQ Estimator,” but I can’t find any evidence that he ever said this, so maybe it’s mine?
"Find the smartest guy in the crowd, divide his IQ by the number of people in the crowd, and . . . there you are."
That’s all there is to it. Humans are not a pack animal, but a herd animal; like buffalo or sheep. Only rarely does the product of a group exceed the sum of its parts. Usually, three of us are dumber than two and, most likely, only one of us in any given group is smart enough to accomplish anything useful. As a nation, we just scouted out the dumbest rich guy in human history and made him our timid, narcissistic, anti-intellectual, anti-science, anti-reality President. If you need more evidence than that, you are the problem.
So, when your “greatest ever” rock band folds after a half-dozen practices and one or two dismal “gigs” (It’s not really a gig if you didn’t get paid for it.), don’t beat yourself up. You are just evidence of the rule, not the rare exception.
