There is nothing a priori in science. Science does not have foregone conclusions. Scientists must be open to any conclusion supported by logic and evidence. Once again, there is no place for politics (or anything else) in science, only logic and evidence. The quality of science – the distinction between “good science” and “bad science” – does not depend on its conclusions but on the logic and evidence supporting them. No scientific conclusions can be good or bad, sexist, racist, offensive, reactionary, or dangerous; they can only be true or false. No other adjectives apply.
