Conspiracy theories are fun, but debunking those conspiracy theories can be even more fun. Dunning does a great job - to the point and often funny.

This podcast consistently gives good advice on how to employ critical thinking. For instance, Mr Dunning gives many examples on how incorrect but inutitively plausible explanations for phenomena are often accepted due to a poor understanding of various scientific fields. I wholeheartedly recommend this podcast.
