Well, you can take a look around and see that there are few real scientists in top positions, esp. in politics. Why ist that? I don't know, but I guess it has something to do with real scientists asking too many questions and being curious by nature (a characteristic feature as scientist come), trying to make the world a better place to live (and getting the Nobelprize for it), having a devotion to their work and not to a political party, etc.

Most "scientists" with a pHD in their name e.g. on TV, talking about genetics, nuclear sciences, environmental problems (or denying those) and medicine, earned it in laws, business, social science or philosophy. Again: Why? When you ask a real scientist about a problem, he would look at it from all sides, state those sides, discuss them and deliver a handfull of different solutions with a recommendation for one or two. You would NOT get a SINGLE, SIMPLE solution which is 100% RIGHT. But that's what politicians want. They need someone telling them which is the one and only solution, and not someone who adds a few problems and complicating the whole mess. Someone who says YES or NO, 0 or 1, 100% and black or white, not someone who says MAYBE, n=0 to 1, 87.6% (not even if you drop a stone will it fall down with a probability of 100%) and infinite shades of grey. So you can't ask a scientist. It's that simple.

PS: As you have surely noticed, I'm a real scientist ;-)
