    Lots of comments relate to racism, so I think it's worth discussing that a little.
    Racism in humans is a very complex phenomenon that can't be simply traced to genes. To be honest, I don't think I really understand racism, but I'm confident saying a full understanding would take inputs from biology, psychology, sociology, and history, perhaps more. But as the video explains, the green beard phenomenon is very brittle and rarely shows up in nature, so it's not an explanation, and certainly not a justification for something as complex as racism.
    Thanks for reading, and be kind to each other. :)

    I wonder if an empathy flag would help the altruism trait flourish. Any time a blob is helped by a green beard, the help-ee would develop "empathy", giving them a small percent chance to pay it forward and possibly develop into a true green beard over time.

    The racism thread seems to be full, but I wanna share my two bits on it:
    Racism is extremely simple: "Person is different from me, I don't like that." You see this all over the place in all kinds of different forms. Men vs women, straight vs gay, old vs young, political parties, and so on.
    "Is there a biological connection?" I don't know. But I know I've seen cats - who were otherwise friends - become nervous when a "friend" suddenly comes home with a lion cut or something like that. Maybe it has something to do with getting away from predators, or, something.

    If you want to code for altruism in humans, make it possible for two creatures to work together simultaneously (thereby knocking the predator out for a generation and both surviving) and have two offspring per person if they both work together.

    I would love to see you run this sim again, but with one change: cowards can learn altruism and altruists can be cowardly (from learning behaviour by way of repeated observation)
    If a blob sees cowardly or altruistic behaviour more than once, there is a 50/50 chance that their behaviour flips.
    Then it would be cool to see this ran further with 'only yellows can learn' or 'only blues can learn' as variants.
    Cool vid - thanks :)

    I can't pretend to be either a geneticist or a sociologist but this really feels more like a social simulation than a genetic one. Like, I know the dude said it was super simplified since there's an insane amount of factors going into this stuff, but it still feels like ignoring those other factors and how observed behaviors affect later actions create the implication that altruism isn't a survival trait even though we know it still exists in people and therefore kinda *has* to have been in some way successful. At least if you connect things like altruism to genetics.
    Course all of that is just to say that, depending on the environmental factors, removing all the "altruistic" traits from a population could potentially lead to extinction in the long run since "every man (or in this case blob) to himself" is a survival trait that doesn't tend to last super long in a lot of social structures.

    Not to mention the short timespan of humans. If the blobs have kids every day, then the 60 day trials are like... 60 generations of people, right? What were our ideas on altruism 60 generations ago IRL? You went up to like 300 days in some trials, which must be on the brink of the invention of the wheel for humans, right?

    The predators are part of the ecosystem too. The more blobs they eat, the more they will survive to reproduce, so there will be fewer blobs to go around, so the predators will be less well fed, so they will survive to reproduce less effectively etc. And don't forget about the trees!

    I think it is better to think of early humans (like hunter gatherers) in small groups and study the survival rate of these entire group, and not as in this simulation, the relative rate of kind of people in a large city. Then if the predator is more aggressive than in the simulation, egoist behavior could lead entire egoist groups to exctinction very fast! Altruism is strictly better with the parameters used in the simulation (even, like, 99% death rate for altruists when they ring the alarm), so we should see altruistic groups go extinct less often. Since early humans looked for mates a bit inside, a bit outside the tribe, the altruistic gene would spread quickly (and even altruistic groups would grow in size).

    One thing you can add is that altruism may be contagious, for example an impostor or a coward could have a 20% chance becoming altruistic after being saved, maybe that could be a solution even though i think that stops being a "genetic point of view" 😅

    As one notable behavioural scientist once said, and I loosely quote, "Characterizing behaviour is like finding the area of a rectangle. You have to have two parameters, height and width. As the area of a rectangle, behaviour is characterized by genes and the environment. The more you focus on one thing the effect of the other will fade away and your results will be completely wrong."
    I see you have only considered genes in this simulation. Therefore, I'm not taking this simulation as a valid argument of how altruism works.
    P.S: Don't get me wrong. I've been a huge fan of your work for a long time. And will continue to be so.

    In this video, we don't really test biological aspects but rather behavioural ones.
    As a consequence, it would be interesting when looking about behaviour or morality to stop calling theses genes but "traits", taught by the parent. Regarding transmission, parents raise their children (as in real life) hence transmitting their traits. This could lead to events called "change of behaviour". For example, a coward saved by an altruist (sucker or green beard) would become altruist after recognising the value of such gesture. On the other hand a "sucker" could become a green beard if it had the chance to save another soul. In this later case, the community recognises the quality of this person. We could add so much complexity to any of these simulations, it is amazing what you are doing thank you.
    End note: it would be important to change the vocabulary as young people also tend to watch your amazing vids in order not to confuse them between what is biological (fixed over the entire duration of your life) and what's behavioural (things learnt that can be unlearnt)

    Models two (cowardly vs altruistic blobs, 50% chance of death if altruism triggers) and three (cowardly vs altruistic blobs, 10% chance of death if altruism triggers) appear to have the results they have due to a MAJOR procedural flaw: no mention is made of whether cowardly blobs can fail to escape predators. The observer can only assume that cowardly blobs will always escape predation, making their survival inevitable.
    That concern aside, I personally suspect that the simplistic coward/altruist model could have been more successful in an environment with a higher proportion of hazardous trees to safe trees. My reasoning is that the effectiveness of a warning call increases the more blobs are warned off by it. There is still the risk that the cycle will just repeat until the altruists have yelled themselves to death until there's not enough altruists visiting the same tree to benefit from this effect, and the additional risk that a high enough predator population might decimate all of the blobs outright, but it is feasible that the simplified model might achieve equilibrium under some circumstances.
    Though in practice, even if cowardly blobs can fail to run away, there's also the flaw that there's no elaboration concerning how effective warning calls are relative to cowardly behavior. Can the warning call fail to alert blobs? Will the chance of a cowardly blob attempting to flee be affected by the presence of a warning call, and if so by how much?
    EDIT: The green beard sim has the same flaws, and relies on the assumption that the cowardly blobs will completely ignore warning calls, so I'm just straight calling bullshit on the utility of this simulation.
