You must have the confidence to override people with more credentials than you whose cognition is impaired by incentive-caused bias or some similar psychological force that is obviously present.

Of course the self-serving bias is something you want to get out of yourself. Thinking that what's good for you is good for the wider civilization and rationalizing all these ridiculous conclusions based on this subconscious tendency to serve one's self is a terribly inaccurate way to think.

Creative accounting is an absolute curse to a civilization. One could argue that double-entry bookkeeping was one of history's great advances. Using accounting for fraud and folly is a disgrace. In a democracy, it often takes a scandal to trigger reform. Enron was the most obvious example of a business culture gone wrong in a long, long time.

I agree with Peter Drucker that the culture and legal systems of the United Statesare especially favorable to shareholder interests, compared to other interests and compared to most other countries.
