This is my question. But, we keep reading in the Chronicle of Higher Ed that it's easier and easier to get into med/dental schools as no one wants to do it, and less qualified people are getting in.
As it is, 50-54% of all applicants are getting into some dental school somewhere. I wonder if he once googled "easiest dental school to get into."
Supposedly, he was well-regarded as a dentist. He went to undergrad at BYU, graduated from dental school at Missouri-KC and was an assistant professor there too. He also did research with NIH.
Sometimes people can be smart in one narrowly focused area, and be an idiot in everything else.
