Was there some sort of prioritization of what bias needs to be attacked hardest to spare us the most damage?

I would speculate when the investigations are finished we will find the BP spill was caused by human error; the biases displayed in making the bad decision were foremost either herd instincts, not wanting to rock the boat, or some very similar cognitively distorted error made by a group of people who all have very high IQ's.

I also think George Bush 2 is a poor example. He is a performer and part of his schtick is not being an uppity intellectual wanker.
