People suppose that hard science is more objective than other subjects such as psychology. But doesn't science require good instincts, judgment, and intuition like any other field does? People say well all the scientists agree that global warming will have a big impact on the world but how can I really be so sure that it's as simple as "science sees it some way so it must be correct?" Isn't it just an unfounded prejudice that scientific judgements can be validated in some essentially simple and uncomplicated way?
