"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."

"Fear is induced by coercion, the threat of negative consequences such as #ostracism and demotion. To be sure, blatant coercion facilitates the denial of responsibility and thereby compliance with corrupt directives. Such coercion, however, leaves less room for (perceived) volition, a key precondition for the dissonance reduction process discussed earlier. Newcomers subject to blatant coercion have a sufficient justification for their obedience – to avoid the threat – and thus do not need to realign their attitudes to accommodate the otherwise dissonant behavior. […] Coercion may affect behavior only as long as the pressure is applied. For these reasons, blatant coercion tends to be an ineffective means of sustaining corruption."
