been the subject of someone's thesis. Waaay back in the early 60s when I was in kindergarten, a group of psychology students from the local university came to our school to test out IQ and knowledge tests on my class (n=26). They then did more indepth research on the outliers with high IQs (me, 126 IIRC). Specifically, they administered a looooong
survey instrument involving both intelligence and knowledge questions. They returned a month later for an unannounced retest. I think their hypothesis was that students with high IQs would research the answers they didn't know. And I had. Specifically, one of the questions I got wrong the first time was "what is ambergris?". FWIW, it's a digestive secretion of the sperm whale. Too bad I never got to read the thesis.
