““In light of all this, we’re now equipped to think about the relationship between laughter and humor. In any given comedic situation, humor precedes and causes laughter, but when we step back and take a broader perspective, the order is reversed. Our propensity to laugh comes first and provides the necessary goal for humor to achieve.34 Humor can thus be seen as an art form, a means of provoking laughter subject to certain stylistic constraints. Humorists, in general, work in the abstract media of words and images. They don’t get credit, as humorists, for provoking laughter by physical means—by tickling their audiences, for example. They’re also generally discouraged from eliciting contagious laughter, that is, by laughing themselves. In this way, humor is like opening a safe. There’s a sequence of steps that have to be performed in the right order and with a good deal of precision. First you need to get two or more people together.35 Then you must set the mood dial to “play.” Then you need to jostle things, carefully, so that the dial feints in the direction of “serious,” but quickly falls back to “play.” And only then will the safe come open, releasing the precious laugher locked inside.36 Different cultures may put different constraints on how a humorist is allowed to interact with the safe, or they may set a different “combination,” that is, by defining “playful” and “serious” in their own idiosyncratic ways such that one culture’s humor might not unlock a foreigner’s safe. But the core locking mechanism is the same in every human brain, and we come straight out of the factory ready to be tickled open, literally and metaphorically.””
