Russ Roberts’ EconTalk episode on my new book is out.  In a world that prized substance as well as style, Russ would be the household name. 

For me, the highlight was trying to convince Russ of the great value of objective testing.  If you’re teaching something existing tests can’t detect, write a better test!  But if you’re teaching something no conceivable test can detect, you probably aren’t teaching anything at all.

Thanks again to Russ for a thrilling interview!
