Focusing on the flaws is vital context for helping ordinary people understand the world. Any given study with a surprising result is likely wrong. Yeah, some of them are going to be right, but you're going to get many false positives and only a handful of studies that replicate to a convincing degree.

I've made this mistake time and time again, most recently with vitamin D association studies, and I'm grateful to all the people who urged everyone else to take a wait-and-see approach.
