The normalisation of corruption in organisations (PDF)
"How can a group hold a worldview so at odds with the wider culture and not appear to be greatly conflicted by it? The answer may lie in the distinction between particularism and universalism. An individual develops social identities specific to the social domains, groups and roles – and accompanying subcultures – that he or she occupies (e.g. manager, mother, parishioner, sports fan). [...]In the case of corruption, this myopia means that an otherwise ethically-minded individual may forsake universalistic or dominant norms about ethical behavior in favor of particularistic behaviors that favor his or her group at the expense of outsiders. [...]
This tendency to always put the ingroup above all others clearly paves the way for collective corruption."
Prioritising the in-group is also how you can take part in genocide. Because you're told so. Because the "other" isn't really human.gwern.net/doc/sociology/2003-a…
