Evolutionarily stable in-group favoritism and out-group spite in intergroup conflict
Open accessAbstract
We study conflict between two groups of individuals. Using Schaffer's (1988) concept of evolutionary stability we provide an evolutionary underpinning for in-group altruism combined with spiteful behavior towards members of the rival out-group. We characterize the set of evolutionarily stable combinations of in-group favoritism and out-group spite and find that an increase in in-group altruism can be balanced by a decrease in spiteful behavior towards the out-group.

Traits such as vengefulness, aggression, risk-seeking, selfishness, dishonesty, deception, and spitefulness towards out-groups could be selected for in ML systems trained in more competitive multi-agent settings.
“Such traits could also be selected for in ML systems that are trained in more competitive multi-agent settings.”

The Conclusions (page unavailable) show that in-group altruism and out-group spite can be evolutionarily stable when two groups compete. The paper does not establish selection for the other listed traits or examine ML systems trained in competitive multi-agent settings; that application is an extrapolation. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
