> "We often follow a secret move immediately with a joke. A viewer has only so much attention to give, and if he’s laughing, his mind is too busy with the joke to backtrack rationally." I've seen this same trick used a lot, by self-serving people who want to convince others of a lie when it's especially not in their favor. It seems very manipulative and wrong.
