Most scientists spend their lives looking for new processes, new explanations and new knowledge. They are by training more open to new ideas than your average person.Does that make them generally less open or more open to new ideas that would go against majority opinion?
However, they also tend to believe in science. So if someone says "I have a theory on stellar formation, and it is supported by these observations" they would tend to be open to it. If someone says "I have a theory on stellar evolution, but it goes against all of existing science, and most of the evidence doesn't support it" they are going to tend to be against it.
I think you are confusing learning how to use tools (like math) and having new ideas.And beyond that, it also would seem like Students going through the education system in Universities would also feel the same Pressure to Conform to Majority Opinion, especially since they could fail their courses it they don’t.
I had a great idea in college on conversion of waste heat to energy. (Specifically a Second Law machine.) It turned out to be wrong. It took me a little while to understand why. I am glad I took the time, though, because that meant that I had learned something. I would still be ignorant if I had said "you are just pushing your outdated ideas on me, and ignoring my great new idea because it doesn't conform to the majority opinion!"
I haven't seen too much evidence of this. I've seen a few cases where bizarro ideas were accepted too readily to the detriment of science and humanity (google Andrew Wakefield) and a few cases where it took a while to get a good new idea established (like the HPV/cancer link.) But they approximately balance outSeems to me like the scale is waited towards conformity to the majority and much less towards new ideas that could challenge existing thought.
