"It also probably works against you in most parts of the tech industry, where there's a surprising amount of blind opposition to anyone with a doctorate." I didn't encounter any doctorate-opposition per se. I think it's more opportunity cost issue. Tech industry is quite meritocratic. Problem for many people with PhDs is that this is the only thing they can show after many years spent hidden in academia, working on e…
Let's be clear: I'm not complaining, nor am I talking about personal experiences of discrimination -- I don't know if my resume has ever been circular-filed because of my degree. But since I left academia I have been surprised by the number of people who have explicitly told me that they consider a PhD to be a black mark on a resume. I think a lot of people have had one or two bad experiences interviewing/hiring PhDs…
Fully agree with what you said - there is a lot of sampling bias because of relative rarity of PhDs (few bad apples can completely color expectations).
It was quite a surprise for me when doing a summer program at major US corporation and everybody was going gaga because our group had many PhDs.
In academia, everybody has doctorate, so degree in itself doesn't really confer any additional signal.
In industry, people take it as a signal even when it is not (person matters more than degree, the same person would be hireable / not-hireable whether having or not having degree).
But anyways, you wouldn't want to work at places / for people which can't / don't take such things into account.
That's why I mentioned meritocracy - it's nicer to work at places where it matters only if you can get the job done, not your degree / pedigree / who-you-know.
But yeah, human nature, hard to fight against, we all like signaling (it's useful heuristics after all).
