Very good, looking forward to part 2 :)
After studying Philosophy of Science at the university, I believe scientists of all sorts should do that for some time – looking at one's achievements and field of work in several perspectives can only help to make it more relevant, and perhaps build some kind of bridges between different fields. But when people identify themselves with their achievements, then experiencing criticism and skepticism can heat up some egos indeed... How can we open up? Is the answer psychological? Because then you have psychologists suffering from the 'I'm right, you're wrong'-disease also :P
