Incompetence plus incompetence equals incompetence

People who are “unconsciously incompetent” don’t know they’re incompetent — they know so little about the subject that they can’t fully appreciate how little they know. That’s why every barber and taxi driver you meet is an expert on the economy and international politics.

A dilemma that I see is that ignorant people are unknowledgable, but can learn. Arrogant people are knowledgeable but unable to be taught.

Senior Management may have been incompetent; it may have been corrupt; it was certainly full of assholes—but they were their incompetent, corrupt assholes.

because complacency, or worse, arrogance, is a parent of poverty.

Dr. Peter observed that one reason so many employees are incompetent is that the skills required to get a job often have nothing to do with what is required to do the job itself. The skills required to run a great political campaign have little to do with the skills required to govern.

Incompetence at this scale, when they're doing things at this scale, is really dangerous, you could end up on a kill list without knowing what the criteria is to get on there or what the criteria is to get off.
