Page "Peter Principle" Paragraph 23

Although humorous, Peter's book contains many real-world examples and thought-provoking explanations of human behavior.

For example, he pointed out that Adolf Hitler was a consummate and superb politician due especially to his charisma and oratorical skills but reached his " level of incompetence " as commander-in-chief of the Wehrmacht because of the rigidity of his decision making ( not allowing retreats when necessary according to the tactical situation ).

Similar observations on incompetence can be found in the Dilbert cartoon series ( such as The Dilbert Principle ), the movie Office Space, and television shows the BBC's The Office or NBC's Parks and Recreation and 30 Rock.

In particular, the Dilbert Principle seems to be an extension of the Peter Principle.

According to the Peter Principle, the subject has been competent at some job in his past.

The Dilbert Principle attempts to explain how a person who has never been competent at anything at any point in time can still be promoted into management.
