In this case, I'll say the criteria is satisfied. "If the state wants to mislead the public they will publish false stats."

In this case, for example, "Incompetence" is a competing explanation. And I have to say, a compelling one.

Yep.

When I was doing ghost investigations, the ghost hunters would say things like, "I feel a presence," or they'd show me orb photos, sometimes they'd report that they literally saw a ghost. This is all 'evidence' but then we put it into the critical thinking meatgrinder and as you point out in point#2, there are satisfactory naturalistic explanations for these. The Natural Sciences don't really have proof, just increasing confidence in one explanatory model.

The challenge is that once you have competing models, you get into calculating probabilities which are often dependent on baselines that have to be assigned.

And this depends on worldviews, which involve trust of information sources and accumulated information drawn from them. We assign probabilities based on these worldviews.


Just as an example from this thread, above I mentioned that a perfectly good explanation for publishing misleading stats three times is incompetence. And unfortunately there's no research we can point to that tells us what the prior probability of incompetence vs deception is for this exact case. We're all just going to go with our gut, juggling a feeling about whether this is a case of 'government in general is incompetent, so high probability' or other partisan interpretations.
