There's been similar cases in physical sciences. E.g. all the room temperature superconductor stuff a few years back, Avi Loeb claiming that an object hurtling thorugh the solar system was alien technology.

There's also more fraud in medicine or health sciences.

You make some very handwavy claims about ideology, do you mean economy by this? It's the most clearly politicized of the social sciences, qnd the one that has been most funded by political actors. This I can concede. But don't throw sociology under the bus just because economy has a bad rap.
