I find it frustrating when well-meaning friends and acquaintances try to convince me of something I know to be a bunch of hooey. When I try to point out that their “facts” aren’t confirmed by science, their standard retort it, “But it works!” As if having something work means it’s true, or right, or God’s will.
From a science point of view, having something work doesn’t prove anything. Just by chance, sometimes doing A will result in outcome B, even if there’s no connection. I’ve said it before: correlation doesn’t prove causation. If you don’t believe me, check out these fun charts.
