When not considering any externalities, anti-vaxxers and everyone that comes up with anti-industry and anti-establishment conclusions is rational, but inaccurate only because they dont consider what was not said.

Even with regard to COVID itself, most of the official communication is about avoiding death when the reality is that its not about only avoiding death its about all the additional debilitating effects in the vast “recovered” statistic, so it is rational to decide to ignore that once you do your own math and noticing who is actually dying. But it is not accurate because it doesn't factor in the unsaid aspect.
