Puns
I really don't think you're engaging with the actual points here, which are (1) that puns and similar jokes can be funny simply by being clever, without any "misplacement" required; and (2) that even when a "misplacement" is involved, your theory doesn't appear to identify any reason why the pun should be funnier than a mere plausible mistake that no one would be amused by.
I agree that the particular one I cited, which was simply the first I had to hand, has an extra layer to it that enhances the humour. I already drew attention to that and made clear that it wasn't the relevant point. Let me try again without that distraction.
I'll take, in fact, one of your own examples, the "kidney beans" joke from your longer paper, which I shall modify a little further to bring out a point. Imagine that you are reading a scholarly article on a cannibalistic tribe in some faraway place, and you find this passage: "The Ougalou people consume human flesh only on special occasions such as a victory over another tribe. Their staple diet otherwise is a dish of kidney beans." I suggest that you might find this quite amusing, if you happened to notice it (I suspect it would be easy to pass over without noticing).
There is no "misplacement" here; the dish of kidney beans is (in my hypothetical scenario) perfectly correct. It's just funny that cannibals should turn out to eat kidney beans. There is no one here to lose status (the author hasn't made any kind of mistake; neither has the reader).
Now let's take an example more favourable to your theory, where arguably there is a "misplacement". It happens to be due to the same person who made the "flushed" pun; it purports (not very seriously) to be a quotation, and it goes like this: <<< "Live fast, die young, and leave a good-looking copse." -- Johnny Appleseed. >>> So, there's a "misplacement" of sorts here: in some sense "copse" is obviously a mistake for "corpse", and with that "corrected" one has the sort of thing that (say) rock'n'roll stars might say. On the other hand, there's a contrasting element of rightness: Johnny Appleseed (as opposed to, say, Johnny Rotten) might indeed advocate leaving a good-looking copse to posterity.
So, does this fit your theory? A "misplacement" (copse for corpse) with some features matching to improve the validity? I don't think it does. For one thing, unless you're unusually quick-witted, there is a definite delay between the recognition of wrongness and the recognition of rightness. So at the point where the wrongness is noticed the extra validity (in comparison with a mere mistake) isn't there. And when does the joke become funny? With the recognition of rightness, not the recognition of wrongness. If it happens to take you a few seconds to see what's going on, the process goes like this: "Huh? I don't get it. Has he mis-spelled 'corpse'? ... Ohhhh, I see." and it's at the latter part -- after any hypothetical status loss -- that you will laugh if you appreciate the pun.
But let's leave all that aside and suppose that somehow your theory can accommodate those facts. What are we left with? Supposedly the pun is funny because it has a bad mistake ("copse" in place of "corpse") but (because the Johnny Appleseed reference kinda-sorta explains the presence of the word "copse") enough validity to ... well, actually this might be a good point at which to mention that I don't see where the validity requirement comes from in your just-so story about status loss: surely a low-validity case is a better sign that someone has demonstrated their unsuitability for leadership than a high-validity case. Well, never mind. Enough validity for laughing at the would-be leader not to anger them too much, or something.
But: "I make typos all the time. I see them all the time". Apparently typographical errors, even when noticed, don't constitute a serious enough loss of quality to be funny. So why would "copse" in place of "corpse" be suitable joke material, on your theory? It's no worse an error -- no more a sign of incompetence -- than my example of "validty" in place of "validity".
All I'm really doing here is giving more examples where "sudden cleverness" rather than "sudden stupidity" seems to produce humour. And, if I understand correctly, your answer to this is that here we are laughing at ourselves rather than at someone else. Leaving aside the question of whether laughing at oneself can be adaptive if the point of laughter is to indicate to everyone around "look who needs to be low-status" (yeah, maybe it could, just as gracefully losing a dominance fight can be adaptive), it seems to me that there is another big problem with fitting these cases into your theory: There is no substantial falling short of expected quality standards here.
Consider, for instance, the corpse/copse pun. If I'm laughing at myself when I laugh at it, what failure of mine am I laughing at? My brief interval of not seeing what's going on? Unlikely -- the pun is just as funny if seen quickly as if seen slowly, and in any case it's hardly a shameful sign of low status to take a moment to grasp it. What else? I don't see it.
Likewise with the kidney beans. What failure in myself am I laughing at if I find it funny to read that a cannibal tribe eats kidney beans when not dining on human kidneys? Again, I don't see it.
Clowns
Yes, indeed, clowns do more than just dress up in silly clothes. I didn't intend to suggest otherwise. My point is simply that their pies-to-the-face and comic pratfalls and absurd misunderstandings and whatnot are displays of conspicuous incompetence from people we expect to show conspicuous incompetence. So Qe-Qd in your equation can't be large because Qe is low to begin with. And yet clowns can be pretty funny.
Novelty
Of course there's no reason why you should be much concerned with novelty. The only reason I brought it up is that you were saying that your theory, if correct, would "redefine the field": I don't think it would.
I really don't think you're engaging with the actual points here, which are (1) that puns and similar jokes can be funny simply by being clever, without any "misplacement" required; and (2) that even when a "misplacement" is involved, your theory doesn't appear to identify any reason why the pun should be funnier than a mere plausible mistake that no one would be amused by.
I feel that puns, when by themselves, all play off of our misplacement instinct. But not all puns are equally funny. Some things are more "out of place" ...
Alrighty, with the mass downvoters gone, I can make the leap to posting some ideas. Here's the Humor Theory I've been developing over the last few months and have discussed at Meet-Ups, and have written two SSRN papers about, in one page. I've taken the document I posted on the Facebook group and retyped and formatted it here.
I strongly suspect that it's the correct solution to this unsolved problem. There was even a new neurology study released in the last few days that confirms one of the predictions I drew from this theory about the evolution of human intelligence.
Note that I tried to fit as much info as I could on the page, but obviously it's not enough space to cover everything, and the other papers are devoted to that. Any constructive questions, discussion etc are welcome.
A "Holy Grail" Humor Theory in One Page.
Plato, Aristotle, Kant, Freud, and hundreds of other philosophers have tried to understand humor. No one has ever found a single idea that explains it in all its forms, or shows what's sufficient to create it. Thus, it's been called a "Holy Grail" of social science. Consider this...
In small groups without language, where we evolved, social orders were needed for efficiency. But fighting for leadership would hurt them. So a peaceful, nonverbal method was extremely beneficial. Thus, the "gasp" we make when seeing someone fall evolved into a rapid-fire version at seeing certain failures, which allowed us to signal others to see what happened, and know who not to follow. The reaction, naturally, would feel good and make us smile, to lower our aggression and show no threat. This reaction is called laughter. The instinct that controls it is called humor. It's triggered by the brain weighing things it observes in the proportion:
Humor = ((Qualityexpected - Qualitydisplayed) * Noticeability * Validity) / Anxiety
Or H=((Qe-Qd)NV)/A. When the results of this ratio are greater than 0, we find the thing funny and will laugh, in the smallest amounts with slight smiles, small feelings of pleasure or small diaphragm spasms. The numerator terms simply state that something has to be significantly lower in quality than what we assumed, and we must notice it and feel it's real, and the denominator states that anxiety lowers the reaction. This is because laughter is a noisy reflex that threatens someone else's status, so if there is a chance of violence from the person, a danger to threatening a loved one's status, or a predator or other threat from making noise, the reflex will be mitigated. The common feeling amongst those situations, anxiety, has come to cause this.
This may appear to be an ad hoc hypothesis, but unlike those, this can clearly unite and explain everything we've observed about humor, including our cultural sayings and the scientific observations of the previous incomplete theories. Some noticed that it involves surprise, some noticed that it involves things being incorrect, all noticed the pleasure without seeing the reason. This covers all of it, naturally, and with a core concept simple enough to explain to a child. Our sayings, like "it's too soon" for a joke after a tragedy, can all be covered as well ("too soon" indicates that we still have anxiety associated with the event).
The previous confusion about humor came from a few things. For one, there are at least 4 types of laughter: At ourselves, at others we know, at others we don't know (who have an average expectation), and directly at the person with whom we're speaking. We often laugh for one reason instead of the other, like "bad jokes" making us laugh at the teller. In addition, besides physical failure, like slipping, we also have a basic laugh instinct for mental failure, through misplacement. We sense attempts to order things that have gone wrong. Puns and similar references trigger this. Furthermore, we laugh loudest when we notice multiple errors (quality-gaps) at once, like a person dressed foolishly (such as a court jester), exposing errors by others.
We call this the "Status Loss Theory," and we've written two papers on it. The first is 6 pages, offers a chart of old theories and explains this more, with 7 examples. The second is 27 pages and goes through 40 more examples, applying this concept to sayings, comedians, shows, memes, and other comedy types, and even drawing predictions from the theory that have been verified by very recent neurology studies, to hopefully exhaustively demonstrate the idea's explanatory power. If it's not complete, it should still make enough progress to greatly advance humor study. If it is, it should redefine the field. Thanks for your time.
