Wise+intelligent people realize that intellectualizing every fucking thing in their life is a trap, and that they should rely more on other things. Not the least of which is buy-in, which is often not about rationality either.
It might take intelligence to notice the problem, but we all know people who haven’t and some who might never. My previous job has the oldest I’ve ever met and I wanted to strangle him at least once a week. I haven’t added anyone to my Do Not Hire list in over a decade. Except him. He made himself indispensable at every opportunity and had some of the most convoluted code (and vocabulary) I’ve encountered in a long time. I spent way too much time extracting his claws from code I’d written that he made an absolute hash of.
