That's just gibberish.

Physics, medicine and so on are full of fraud. It's rather common in academia. The social sciences can tell you why, math can't.

The "why" is utterly irrelevant if you can't then do anything about it. It also seems like some of that "why" research was fraud too, so they couldn't even answer that.

Meanwhile the hard science guys are forcing retractions.

Let me introduce you to one of the main driving forces behind retractions, PubPeer: https://pubpeer.com/

..and?

I think it's sprinkled all over this thread.

Social science can tell you why, absolutely. But then can't replicate it.

The "replication crisis" reaches way beyond social sciences, and not all scientific epistemologies are founded in so called replication.

Ok.
