I need to start this weblog publish with a confession. I’ve by no means been into recreation concept, and though I did take some undergraduate programs in it, I’ve at all times struggled to know all of it. However whereas I used to be considerably uneasy about recreation concept (or at the least components of it), I couldn’t categorical the explanations for my reservations. It was extra of a sense.
From nowadays, I nonetheless keep in mind a dialog I had with a fellow undergrad (maybe she had additionally lately graduated) about recreation concept. She was somewhat keen on it and gave good arguments about why it was useful and good. Again then, one of many criticisms I voiced was that recreation concept struggled to elucidate cooperation, or so I believed.
What made me surprise was how precisely recreation concept may clarify cooperation if it assumes that individuals are egocentric and maximize their (narrowly construed) anticipated utility. She responded, “Oh, that’s not a giant deal. When you assume iterated video games, it’s rational to cooperate.” In and of itself, the reply appeared convincing. In spite of everything, if we anticipate seeing one another greater than as soon as, we should always modify our behaviour accordingly. After which it could actually be “rational” to cooperate and never defect. So, that day, I left it at that. However I couldn’t fairly shake off a sense of uneasiness with that resolution.
Issues modified after I learn Joe Henrich’s monumental work The WEIRDest Individuals within the World, revealed in 2020. Henrich does many issues on this tract, however he additionally touches on life in prehistoric occasions. And in an intriguing passage, he displays on interactions between people. Henrich (p. 303) writes:
WEIRD individuals are inclined to suppose that commerce is easy: we’ve wild yams and you’ve got fish; let’s swap some yams for some fish. Simple. However, that is misguided. Think about attempting to barter yams for fish within the hunter-gatherer world described by William Buckley in Australia. On this world, different teams had been usually hostile, and strangers had been steadily killed on sight. To hide their nocturnal areas, bands erected low sod fences round their campfires so that they couldn’t be noticed from a distance. If I confirmed up at your campfire with some yams to commerce, why wouldn’t you simply kill me and take them? Otherwise you might need thought we’re solely providing our poisonous yams, which might slowly poison you and your band. Beneath such circumstances, which had been in all probability frequent over our species’ evolutionary historical past, it’s tough to see how easily flowing commerce may ever emerge.
If Henrich is correct, then we can not merely assume that there might be a second spherical, to not converse of video games with infinite rounds. Certainly, maybe the standard form of interplay can be the try and kill one another. Or the 2 would chorus from interacting with one another in any respect.
But when, for this or that purpose, there had been a second spherical, that might presuppose that there was a primary spherical of interplay and that it had been peaceable. For instance, we had exchanged yams for fish. To the least, we didn’t kill one another, both with our spears or poisoned yams. However that is, or at the least may be very near, cooperation within the sense of peaceable, coordinated, and reciprocal interplay—if solely in a really crude and fundamental type.
Following Henrich, then, the sheer reality that there’s a second spherical of interplay, that’s, that our recreation began in any respect, and if it began that it doesn’t finish after the primary occasion (as a result of both I killed you otherwise you killed me, or to the least, the interplay was so distasteful that none of us sees any purpose to work together with one another once more), requires a fundamental degree of cooperation.
However this means that recreation theorists’ assumption of iterated video games to exhibit that cooperation is feasible and does, certainly, observe in game-theoretic eventualities, is a petitio. They already assume that individuals’s interplay might be characterised by fundamental cooperation or at the least peacefulness once they assume that individuals will face iterated and even infinitely iterated video games, that’s, don’t kill one another at first sight. Subsequently, recreation concept covertly assumes cooperative and peaceable interplay to elucidate cooperation. And that’s problematic.
I wish to come again to the remarks I made initially of this piece. I’m under no circumstances an professional within the area of recreation concept. I’m simply an outsider who places ahead his ideas about recreation concept—a critic who, certainly, might miss the forest for the timber. However maybe commenters on this weblog can present me the place my reasoning goes mistaken. Or, maybe, my critique has one thing to it, and recreation concept has some work to do.
