This is true. Accurate portrayal of scientific methodology is to note how scientists, just as emotional people like all others, employ objective non-emotive metrics to attempt to provide logic. If the concept passes majority acceptance to the science community (not 100%!) then it is presently taken as fact, such as global warming. But this acceptance can always be negated if new data is found. So the process continuously evolves the answers we accept. Ex: Pluto is not a regular planet anymore.
