  • Because religion evolved to thrive in us.

    It’s like a parasite, and our mind is the host. It competes with other mind-parasites like other religions, or even scientific ideas. They compete for explanatory niches, for feeling relevant and important, and maybe most of all for attention.

    Religions evolved traits which support their survival. Because all the other variants which didn’t have these beneficial traits went extinct.

    Like religions who have the idea of being super-important, and that it’s necessary to spread your belief to others, are ‘somehow’ more spread out than religions who don’t convey that need.

    This thread is a nice collection of traits and techniques which religions have collected to support their survival.

    This perspective is based on what Dawkins called memetics. It’s funny that this idea is reciprocally just another mind-parasite, which attempted to replicate in this comment.




  • Yes, and no.

    First and foremost, you need no “justification” for being a decent person. And there are other reasons to be that way, as arbitrary as “I like it this way”.

    Game theory is strongly related to evolution. It is safe to assume that everything we can observe in nature is a successful strategy. So this confirms the statement: Cooperation is a successful strategy. But the other side of the picture also exists: Betrayal is as well.

    What the excerpt omits about the Prisoner’s Dilemma (not sure wether it’s mentioned in the video, which I did not watch now): The Nash Equilibrium can be the overall worst outcome. What does that mean?

    A Nash Equilibrium is a situation in which no player can improve their own position. It is therefore a stable state. Things will change until they have settled in a stable state. It can be shown for Prisoner’s Dilemma that the Nash Equilibrium can be the worst case, where each betrays the other. Yes, they would both score better if they cooperated, but the system will still tend towards the state where both play nasty.

    When multiple iterations are played, this changes a bit. It seems, if you not just meet once in a lifetime, but can remember your past, and have a common future, it makes more sense to cooperate. But there is still a place for uncooperative exploitation.

    So yes, it’s true what you say about “best performing strategies”, but it should be noted that “evil” strategies don’t go extinct either.

    It should be questioned how much these theories can be applied to our lifes. I mean questioned, not implying an answer. Either way I find it interesting how behaviour which we associate with morals emerges in very simple and abstract games.
