Galileo was no conspiracist, at least not by the definitions used today. Galileo believed an alternative (Copernican theory, and had evidence) more than he disbelieved the authority (the Vatican). The only reason he recanted was to save his head.

Perhaps without the benefit of our 400 years of hindsight you might have an argument that under the context of his era he would appear to be a conspiricist, but in reality that would be an incorrect attribution.

The difference, as pointed out in the paper, is that conspiracists and conventionalists think and argue with different rationales which lead to their respective belief systems.

It took nearly 400 years, but the Vatican eventually admitted their error.

Noah? Yeah, he was a prepper. The argument would be why people are preppers. Some do it for rational reasons, others are conspiracists. I would not consider the label "prepper" to be indicative of the person being a conspiracist or a conventionalist.
