IMHO, there are different types of intelligence. My wife being in the medical professions, I’ve noticed that liberals far out number conservatives in any gathering of doctors, nurses, and advanced practitioners. No one is ever going to accuse anyone there of lacking intellect.
I’d also conjecture that to a degree their liberalism might even benefit them professionally. Whereas I’d want a conservative lawyer or a conservative accountant, I can see where being a bleeding heart isn’t a bad quality to have in the nurse taking care of you.
I think that’s true. The other commonality that occurred to me is that the median age is fairly young among techies, and the young in general tend liberal.
I want MY surgeon to be a rabid , competititve, cold hearted decisive character!
