This is actually something I feel strongly about. The absent minded creative professor is the one who traditionally has made the breakthroughs. Recent years has instead seen the straight A student with no curiosity making it into programs, when they really have no business doing novel research and are better suited as orderly wage slaves

There's a lot of fanciful stuff about "creative" and "absent-minded" people doing the best work, but what actually makes a good researcher is the same as in any other field: (a) curiosity (b) determination, and (c) hard work.

PhD programs don't take people who just have a good GPA; you have to have a research record before you're even in the consideration. I've been on an admissions committee, so this is not conjecture.

Right, but a modern research record is about incremental improvement. The argument being that low hanging fruit is often picked, and so the incremental is natural. My argument is that far too many people are gaming the academic system, using it as a form of status credentialing, which is hurting true academic research.
