Exactly. People tend to overstate the importance of spurious, surprising findings that don't make scientific sense. Some of these may lead to breakthroughs, sure. But the overwhelming majority are just noise. And it takes experts to decide which are worth investigating. To wit, anti-vaxers love subgroup analysis without supporting scientific logic (ie more autism in this population of 5 boys from the study).

I'd hate to see old, frail people getting Etanercept (an immunomodulator) to prevent Alzhemier's based on very questionable evidence when all they really get are the costs (increased risk of serious infections leading to death-- an FDA black box warning).
