CH points to this illustrative study on the game theory of ethnocentrism, “The Evolutionary Dominance of Ethnocentric Cooperation”, the abstract of which reads:
Recent agent-based computer simulations suggest that ethnocentrism, often thought to rely on complex social cognition and learning, may have arisen through biological evolution. From a random start, ethnocentric strategies dominate other possible strategies (selfish, traitorous, and humanitarian) based on cooperation or non-cooperation with in-group and out-group agents. Here we show that ethnocentrism eventually overcomes its closest competitor, humanitarianism, by exploiting humanitarian cooperation across group boundaries as world population saturates. Selfish and traitorous strategies are self-limiting because such agents do not cooperate with agents sharing the same genes. Traitorous strategies fare even worse than selfish ones because traitors are exploited by ethnocentrics across group boundaries in the same manner as humanitarians are, via unreciprocated cooperation. By tracking evolution across time, we find individual differences between evolving worlds in terms of early humanitarian competition with ethnocentrism, including early stages of humanitarian dominance. Our evidence indicates that such variation, in terms of differences between humanitarian and ethnocentric agents, is normally distributed and due to early, rather than later, stochastic differences in immigrant strategies.
CH adds:
Every virtue signaling White sh*tlib should read this research paper and absorb the lessons therein. You can have your harmless virtue signals, or you can have open borders, but you can’t have both, because the rest of the ethnocentric world doesn’t share your moral universalism and will, if permitted to live in close proximity to universalists, ruthlessly capitalize on the latter’s gullibility, trust, and knee-jerk cooperativeness, reconfiguring their virtue signaling into virtual suicide.
If, while perusing the abstract above, you were reminded of a certain ethnocentric tribe exploiting a universalist majority, you aren’t meshugana.
It is through the lens of evolutionary group strategy that one must understand SJWs; BLM; the mainstreaming of anti-white animus; the tearing down of statues; the hysteria around ‘It’s okay to be white’; La Raza; and Kevin MacDonald’s pioneering work on Jewish ethnocentrism and Jewish undermining of social capital in high-trust, universalist, white European societies.
