Scientific training is specifically training in reasoning to a much greater extent than is, say, political training. Smarter people are better than dumber people at reasoning on average, but the advantage of scientists over politicians is less that they are smarter (they are, but only modestly) than that they are selected for and trained in reasoning well while politicians are selected for and trained in reasoning poorly.
