This is SO common and people never want to admit it. The real question is what made you finally go read the actual paper? Was it someone pushing back on a post you made, or did you just stumble on a breakdown of it somewhere? Because I feel like most of us only check the source when somebody calls us out on it. And once you saw the study was junk, did you go back and delete your old posts or just quietly stop sharing it and hope nobody noticed?
