I wrote a whole chapter about this in Fiat Ruins Everything about how Fiat Money has ruined Science. For example, the entire "science" of climate is driven by political considerations through grants, which, of course, is driven by fiat money. What's surprising is how slow scientific progress has been because of how politicized it's become.

It turns out that truth does not give itself up very easily, and anything less than a complete and dogged pursuit of it will fail.
