What do you think when you hear someone complimented as being "a first a principles thinker"?
@ntnsndr Depends a lot on the irony/cynicism level of the complimenter!
Insufficiently aware folks might use the phrase positively.
Those who have been around a while, and notice all the awful crap self-identified "first-principles thinkers" inflict on the world? They'd be using it in the derogative sense π
