Pointing out someone's conclusions are incorrect is useless unless you also point out why they're incorrect. Everyone has an opinion, it's the reasoning that matters. In some fields, like mathematics, pointing out "this result is incorrect" can be useful in itself, but that's because of the deeply technical nature of mathematics itself - mechanical verification of correctness is feasible. In ordinary conversation, things aren't that black-and-white, and pointing out that something is wrong doesn't in itself provide valuable input for self-reflection. Providing some more information why is always more helpful than just saying "you're wrong, figure it out".
