Do you have any evidence for that? ;-) The world is a complicated place and the truth is hard to find. Unintentional confirmation bias is a thing. Intentional (at some level) cherry-picking to support your preferred answer is a thing too. But that doesn't mean that nobody ever learns anything from looking at data. If someone claims to be "evidence-based", then their intention should be given the benefit of the doubt. They may be affected by confirmation bias, but that doesn't mean their conclusions are wholly baseless. You should take a look and see how they're doing before dismissing them out of hand.
