How can systemic corruption persist in a real institution when most employees are not corrupt?
I’m researching this for a thriller and want the institution to behave plausibly rather than like a giant conspiracy.
I’m especially interested in how a compromised system can continue functioning when only a relatively small number of people are actively corrupt.
In real organisations, what mechanisms allow that to happen?
For example, can corruption persist through things like compartmentalised information, fear of retaliation, career incentives, procedural obedience, selective enforcement, management pressure, people assuming someone else has checked something, or employees seeing only one small part of a larger pattern?
I’m also interested in the people who are not corrupt themselves. How might an honest employee unknowingly help a corrupt outcome happen simply by following normal procedure?
And what tends to happen when someone inside such a system begins noticing inconsistencies but does not yet have enough evidence to prove deliberate wrongdoing?
I’m looking for real-world organisational dynamics rather than advice on plotting the story.
