===Strong reciprocity (or "tribal reciprocity")===
{{Main|Strong reciprocity}}

Humans may have an evolved set of psychological adaptations that predispose them to be more cooperative than otherwise would be expected with members of their tribal [[ingroups and outgroups|in-group]], and, more nasty to members of tribal [[ingroups and outgroups|out groups]]. These adaptations may have been a consequence of tribal warfare.<ref>{{cite journal | last1 = Bowles | first1 = S | year = 2009 | title = Did Warfare among Ancestral Hunter-Gatherer Groups Affect the Evolution of Human Social Behaviors | journal = Science | volume = 324 | issue = 5932| pages = 1293–98 | doi=10.1126/science.1168112| pmid = 19498163 | bibcode = 2009Sci...324.1293B | s2cid = 33816122 }}</ref> Humans may also have predispositions for "[[Third-party punishment|altruistic punishment]]" – to punish in-group members who violate in-group rules, even when this altruistic behavior cannot be justified in terms of helping those you are related to ([[kin selection]]), cooperating with those who you will interact with again ([[Reciprocity (evolution)#Direct reciprocity|direct reciprocity]]), or cooperating to better your reputation with others ([[indirect reciprocity]]).<ref name=gintis2000>{{Cite journal | last1 = Gintis | first1 = H. | title = Strong Reciprocity and Human Sociality | doi = 10.1006/jtbi.2000.2111 | journal = Journal of Theoretical Biology | volume = 206 | issue = 2 | pages = 169–79 | year = 2000 | pmid =  10966755| bibcode = 2000JThBi.206..169G | citeseerx = 10.1.1.335.7226 | s2cid = 9260305 }}</ref><ref name=henrich2012>{{Cite journal | last1 = Henrich | first1 = J. | last2 = Chudek | first2 = M. | doi = 10.1017/S0140525X11001397 | title = Understanding the research program | journal = Behavioral and Brain Sciences | volume = 35 | issue = 1 | pages = 29–30 | year = 2012 | pmid =  22289319| s2cid = 39959479 }}</ref>
