[the following recounts an exceptionally powerful teaching technique employed by an economics professor of mine at university; teaching fact-checking and skepticism by salting it into the content of his delivery]
One of my favorite professors in college was a self-confessed liar.
I guess that statement requires a bit of explanation.
The topic of Corporate Finance/Capital Markets is, even within the world of the Dismal Science, a exceptionally dry and boring subject matter, encumbered by complex mathematic models and obscure economic theory.
What made Dr. K memorable was a gimmick he employed that began with his introduction at the beginning of his first class:
"Now I know some of you have already heard of me, but for the benefit of those who are unfamiliar, let me explain how I teach. Between today until the class right before finals, it is my intention to work into each of my lectures … one lie. Your job, as students, among other things, is to try and catch me in the Lie of the Day." And thus began our ten-week course.
