So many dumb PhDs out there dude. I have quite a few as customers and I can tell you the only ones with common sense I've known are practicing surgeons, archeology (according to my wife), and anthropology.

All the other ones have less common sense than a child and get taken advantage of, both intentionally and by idiots who also don't know what they're doing, easily 3x as much as your average Joe. Don't even get me started on the psychology PhDs...

I think the defining factor is that the above three, as well as a few others I don't know individuals in, require working knowledge outside of their field of study. A surgeon might know the body inside and out, but they also must learn other soft skills like bedside manor and seeing the reality of death.

A psychologist can see just about anything in the world and still dial it into their field and ONLY think of it in those terms. Not all cases obviously, but these are my personal observations.

I think what makes or breaks a field is real feedback. Lots of fields filled with smart people are experimental or have some sort of way where the physical universe can clearly tell you that you’re wrong. Doctors have patients die, engineers have bridges collapse, etc. 

Fields where the only determinate of what’s right or wrong is other academics, or that they are far removed from results (social scientists pushing for a policy where results of it are revealed 20 years laters), or involve shoddy statistics as the only way of measuring success, are filled with idiots. 

In experimental fields, you can’t be dance around and explain away lack of results. You gotta get it right, and to do that you have to be smart. If you read the words of said dumb people, you’ll see they’re excellent writers. They’re great at what’s most important to them, dancing around failures and explaining them away. No wonder they’re all politicized
