Book review: Inside Jokes – Using Humor to Reverse-Engineer the Mind, by Matthew M. Hurley, Daniel C. Dennett and Reginald B. Adams, Jr.
This book has the best explanation I’ve seen so far of why we experience humor. The simplistic summary is that it is a reward for detecting certain kinds of false assumptions. And after it initially evolved it has been adapted to additional purposes (signaling one’s wit), and exploited by professional comedians in the way that emotions which reward reproductive functions are exploited by pornography.
Some of the details of which false beliefs qualify as a source of humor and how diagnosing them to be false qualifies as a source of humor seem arbitrary enough that the theory falls well short of the kind of insight that tempts me to say “that’s obvious, why didn’t I think of that?”. And a few details seem suspicious – the claims that people are averse to being tickled and that one sensation tickling creates is that of being attacked don’t seem consistent with my experience.
They provide some clues about the precursors of humor in other species (including laughter, which apparently originated independently from humor as a “false alarm” signal), and give some hints about why the greater complexity of the human mind triggered a more complex version of humor than the poorly understood versions that probably exist in some other species.
The book has some entertaining sections, but the parts that dissect individual jokes are rather tedious. Also, don’t expect this book to be of much help at generating new and better humor – it does a good job of clarifying how to ruin a joke, but it also explains why we should expect creating good jokes to be hard.
