Sure, but there's a level of entry to the "challenge" call to action. When folks are saying "believe in the science", it also means to believe in the scientific method, which does include challenging observations and independently validating conclusions. A proper challenge requires coming up to the plate, proposing a challenging hypothesis to a given conclusion, and then going through the work required to test your hypothesis, documenting the inputs, the variables, and showcasing your outputs. What this doesn't mean is the average human who does not like the conclusion producing a statement saying "I don't think that's real", or even going so far as to cite data which could appear to refute the conclusion, are producing a challenge to the conclusion. They're just stating an opinion. This isn't designed to be exclusionary, but to ensure that challengers are going through the effort that the producer of the conclusion did. If one is not willing to learn the problem space enough to reasonably challenge the effort, then that challenge is moot.
