Any of us who have taught at the university level have little trouble identifying those who should not really be there...but somehow have managed to get good grades. The truth comes out when they are caught unaware, and one can observe their logic operating without the shield of preparation. It’s a bit harder in the lib arts, since one can lie and appear bright. Of course, we all know of the uber lier - Bubba Bill. His answers appear bright, but deeper analysis always shows the lawyer touch - nice words, but little substance. This woman is insecure, brittle, and dumb!
