  1. Why is altruism more common in nature than spite? This new paper gives a general mathematical explanation: the degree of negative assortment that can be achieved is constrained in a way that positive assortment is not, particularly in unbalanced populations.

  2. Analytic solution for the stationary distribution of actions taken in iterated games with implementation errors, and code to automate the solution in SymPy.

  3. I recently read a paper by Kleshnina and others and used it to teach myself some evolutionary game theory techniques.

    This is a little obscure, so I'll thread below about why this topic matters for humans and the environment 🧵

  8. Martin & Lessard (2024) find that assortment generally increases the fixation probability of Cooperation (C), but not if payoffs are multiplicative such that a Defector receives a much larger payoff than C in groups containing a very large number of C individuals.

  9. I'm gonna have to read it more carefully but at first glance this looks like it might be an #EvolutionOfCooperation ground-breaker.

    It's worth mentioning that the first thing that occurred to me when I saw this is that money serves this same same social purpose of creating "artificially amplified" incentives for cooperation within a population, but modeling a shared currency as a special case of institutions is actually a better, more generic way to look at it!

  10. I'm not a fan of Dominic Johnson's Supernatural Punishment Hypothesis. Not actively hostile to it or anything, but it seems kind of just-so as anthropology, and it's even less plausible as a driver of genetic selection.

    Anyway TIL that an IPD agent model they did in 2016 to demonstrate it didn't even show the expected selection strength "in silico" and I have to admit I found that funny. 😀 #EvolutionOfCooperation
