I'd need to see some rigorous comparisons to other professions to conclude it's "so common". The mere act of naming an "engineer's syndrome" could arise from the fact it's peculiarly remarkable against type, or satisfying to resentful observers - rather than actually common. And, once named, such a designation would tend to collect confirmation-bias-feeding anecdotal examples. I've encountered cranks from every walk of life. I see more engineer cranks, too, but that's simply because professionally, I interact with more engineers than, say, hairstylists or bricklayers or actresses. And have you ever let a taxi/uber driver just expound on their confidently-expressed theories-of-the-world?
