A well trained scientist with a Ph.D. or similar advanced degree and research experience has been trained to identify a problem, formulate a hypothesis, which is an interrogation of said problem, test the hypothesis and learn from the observations. This process requires open minded thought through and around complicated subjects and to understand cause and effect. If you change one thing, other things must change, is a concept that scientists are very familiar with. For politicians they change a bill or a law to increase its appeal for some other law makers. A solution is to throw money at a problem and let other people sort out details. But we need detail oriented minds in congress and less capricious spending.
Scientists are trained to be experts in a focused field of study but understand how that focus impacts the big picture. Therefore scientists are likely better able to see problems with details or gaps in the big picture. A scientist engaged in writing a research paper is trained to acknowledge the opinions of others or even weaknesses in a concept. This can be applied to making laws or policy such that the greatest good for society can be achieved.
