The stability of group status hierarchy regimes raises the question, what motivates individuals to follow the norms that sustain the regime and to punish those who deviate even though following and punishing incur costs and often run against the individual's self-interest. Part of the answer appears to be that in an ongoing status hierarchy, people internalize the norms and esteem those who follow the norms, and the desire for this esteem motivates one to conform. Expressing admiration of those who adhere to social norms one accepts is often not costly behavior for an individual, but rather a pleasant activity. Moreover, we humans evidently have a native disposition to be rule-following punishers, who tend to accept current dominant social norms and to desire to punish those who violate them even when doing so is disadvantageous for us (Bicchieri 2006: chapter 3 and Henrich and Henrich 2006: chapters 7–8). The same generic trait that leads us to be disposed to punish those who steal and lie and neglect their children can also lead us to be disposed to punish those who challenge established group status hierarchy norms such as white supremacy.  State-enforced laws can help create and sustain such a regime, as with Jim Crow segregation laws in the U.S. South in the twentieth century, but discriminatory social norms can arise and thrive and confer benefits on dominant caste members in the absence of legal enforcement.
