Given my background in the sciences (bachelors of science from a research university *cough* bragging *cough*), I like to think of laboratories and the science community in general as composed by those who uphold themselves to a high standard of objectivity. You know, sticking to the facts.
Studies that give results making for easy click-bait and general outlandishness are easy to call out for what they are. "Is it a peer-reviewed publication?" is a good place to start. But what do you do if the lab is working for an agency? Who is reviewing them?
