I recently watched an episode of Part of the Problem, With Dave Smith, and it was them criticizing a recent interview with Sam Harris. During this episode Dave says that Sam is a smart guy, but I'd disagree. Sam is knowledgeable in the very particular fields that he's studied, but I don't consider knowledge to be a sign of intelligence, it's a sign of memorization. On the other hand I've observed Sam fail to apply logical thinking, which I would consider to be a mark of intelligence, as it demonstrates an ability to consume information and process it critically and rationally.
