A Note from the Editor

Every piece on GetClariSync starts with a question I had — usually one where the popular answer didn't match the underlying evidence. We trace claims back to primary sources, weight replicated findings above single studies, and update articles when better evidence emerges.

If we change a substantive claim, we say so.
