Inquiring Mind examines hubris syndrome:
You look upon the world as an arena in which to exercise power and find glory. Your confidence in yourself is unshakeable. You are restless, impulsive – reckless even. Detail bores you. Oh yes, and God, or history, or both is firmly on your side. No need then to listen to the little people. You are suffering from Hubris Syndrome.
The longer you stay in office, the longer you are cocooned by deference, the more your sense of omnipotence grows, the greater the chance you will contract HS. That’s bad because HS leads almost inevitably to flawed reasoning and a blindness to alternatives – or ”hubristic incompetence” as Lord Owen describes it. But it isn’t just about position; there must be some kind of predisposition in sufferers.
The OED defines hubris as insolent or overweening pride leading to nemisis. It sounds very like Ozymandias Syndrome.
