Sure, at the end of the day there is no reliable way to tell truth from falsehood except by thorough scientific investigation.
But the topic at hand is whether, in the absence of the time or other resources to investigate everything, there are guidelines that will do better than random chance in telling us what’s promising enough to be worth how much investigation.
