Like most things with the brain, we don’t know.
It seems to be a social thing. We laugh because other humans laugh and joking and laughing are a way to build relationships. Remember, humans ability to communicate (and teach) is our biggest evolutionary advantage.
There does seem to be a part of the brain that has the job of predicting what will happen next. This is to anticipate danger and such, yes, but also during conversation you are planning your response. So what happens is that you hear the set up to a joke, and your brain starts to predict what will happen in the rest of the joke. But then the punchline is unexpected and it trips up what your brain predicted. And for some reason, we find that dissonance funny. Of course, context matters a lot and the difference between an unexpected joke and an unexpected scare is all about that context.
Evolutionary Predationist here: It’s little-known, but “humor” is actually a stress response. Specifically, it’s a response to situations which cannot be easily classified among “known stressors”, such as predators, environmental hazards, or the like.
When presented with an unfamiliar or unexpected condition, the mind doesn’t immediately “know” how to react. This is a form of stress, but as the stressor is unexpected, the mind hasn’t developed a specific, situation-appropriate response.
Socially-based creatures have actually evolved a ‘catch-all’ response to such unexpected stressors. This response typically manifests as a distinct, involuntary vocalization which alerts all nearby members of the ‘pack’ to the occurrence. Greater numbers allow the group to analyze the event in greater safety. Among humans, this vocalization is well known as laughter.
Comedy is essentially the art of manipulating this stress response in such a way as to be considered pleasurable. Furthermore, I’m talking completely out of my ass. I’m a musician. There’s no such thing as an “Evolutionary Predationist”.
God has a sense of humor, and if we’re made in God’s image, we, too, have a sense of humor, even the darkest souls among us.
What makes me laugh isn’t just a brain reaction to stimuli. I’m aware that I am more than my brain and my response to something humorous. There’s something in our soul that allows us to feel pleasure from laughter. It makes our body, brain, heart and spirit happy for reasons beyond, “1 + 1 = 2”.
Laughter is something we are literally born with, outside of brain damage that inhibits that natural birth right.
