Too often we allow the forces of anti-science, the forces of denialism, or contrarianism, to somehow frame their position as one of skepticism. But denying mainstream, well-established science based on arguments that don’t stand up scrutiny, that’s not skepticism. That’s pseudo-skepticism.
Real scientists embrace skepticism because that’s what moves science forward. That’s the self-correcting machinery, to use the language of Carl Sagan, which keeps science on this inexorable course toward a better understanding of the way the world works. If your ideas are wrong, if your theories are wrong, if they don’t hold up, if the data don’t support them, if other studies don’t come to the same conclusion, then science moves on, and it searches for a better answer. Scientists are always trying to find holes in each other’s proposed ideas, or in their own proposed ideas.
