Many statements from the summary directly contradict my personal experience. The summary states:
"Survey data indicates engineering faculty at universities are far more likely to be conservative than people with other degrees, and far more likely to be religious."
Well, I'm an engineer and I work with engineers all day. I find the majority to be fairly liberal and not very religious. I always thought that it was a result of people being intelligent and familiar with the scientific method that made them less likely to swallow propaganda and dogma. Also, it is a largely foreign population and that is a factor since I meet the people who were educated enough to get jobs in different country from their own. I find that it is we Americans who are conservative and religious.
Also, the summary states:
"Gambetta and Hertog speculate that engineers combine these political predilections with a marked preference towards finding clearcut answers."
I speculate that Gamgetta and Hertog are fearful and jealous of engineers. I work in chip design and there are very few clearcut answers. Furthermore, your opinion on whether or not something is a good idea has no bearing on whether or not it actually is. I find that to be a major difference between engineering and the the more "normal" fields; you have to build things that work in the real world, your ability to persuade someone will not improve the quality of whatever it is you are building. If my chips don't work, I can't argue in front of a judge that they really do work. Nor can I publish a book speculating how good they really are. No, I fscked up and I have to deal with it.
