Eric,
Serious question: I find that the core issue in corruption, and the corruptibility of an individual and then the groups they are a member relies on plain spoken communication skills, and the ability or inability of an individual to protect themselves from self deception.
A "uncorrupt person" does not choose to be corrupt, they lie to themselves with little corruptions until "it is too late" and then with no (self assessed) alternative they commit to their situation.
As well as a group of people knowingly engaged in less than ethically honest activities must impress their ethical failures on all their peers, to insure their safety if the corruption is exposed, and they then bully their uncomprehending peers into corruption.
All of this is caused to the educational hole that is effective communications: people are not taught how to identify honest and dishonest self conversation, people are not taught how to communicate without information mistakes they refuse are mistakes, omissions of critical information, and then deferment of blame when half considered strategies are met by complex reality.
I've been working in tech, at all levels, since the 70's. The #1 characteristic of every single organization I have been a member and interacted with is poor communications, weak documentation, and nobody able to discuss the topics at hand without technical pretension, omissions, misdirections, and misinformation.
This nonsense is all due to no real emphasis on communicating to mutual understanding anywhere in the verticals of technical and science educations. And that includes the communications in people's heads that drive them to comforting non-solutions they attempt and fail.
