Many jokes, particularly puns and one-liners, rely on on setting up expectations, just to subvert them, on double meanings and ambiguity. Take this one:

I would tell you a chemistry joke, but I wouldn’t get any reaction.

Whether you find it funny or not, you can see that it’s all about the double meaning of “reaction”. And that would never work if, when understanding one meaning, you immediately forgot the other. It’s as if, as the joke unravels, “reaction” gained two incompatible meanings simultaneously.

You know what else behaves in multiple, incompatible ways at once? Good old quantum objects.

When measuring the properties of quantum systems, the results depend on context. How you measure the system matters, as does how you prepared your system for the experiment. Something similar also holds for jokes: who tells the joke, how they deliver it, and in what context can make the difference between funny and offensive. Seth Myers has a whole segment based on this.

According to a recent paper on Frontiers of physics, quantum mechanics could be the way to approach humor mathematically. However, as the scientists are quick to specify, this does not mean that humor has any sort of actual quantum behavior. Just that the same math tools could work in both cases.

In this “quantum” framework, the joke-teller sets up some superposition state of words, which now has two meanings at once (like that famous dead and alive cat). As listener gets the joke, they “measure” its funniness, which is a different property (in quantum speak, it’s a different basis), but is also in superposition. Following quantum rules, the measurement destroys the superposition, it picks one of the possible results: either the joke is funny or it’s terrible. Which is picked depends on the listener, on how it was set up, on context, etc.

It’s pretty cool, but researchers only got preliminary and “not terribly surprising” results (their words) from experiments, so it’s not quite clear whether this method can actually work. Still, comedy has used science for years: in movies, TV and comics (just to name a few). Now it could be payback time!
