No it won’t - the vast majority of the perpetrators, perhaps rightfully, will think that doesn’t apply to their case because of their instititional politics.

I think it's more how the incentives in the system are set up. Unless the incentives change (publish or perish, gatekeeping journals, etc.), then nothing will change.

This is the real answer.

Many of the problems in academia are due to publish or perish. Very many of them.

Three or four cases of entire laboratories or departments being shut down for fraud would make a dent.

Just look at all the high profile academic fraud cases in politics - Von Der Leyen (President of the EU Commission, plagiarized half of her dissertation, zero consequences), Aschbacher (Former Minister in Austria, her thesis was filled with grammatical and logical errors that would've shocked a high school teacher, gets to keep her PhD), Voshmgirs (Founding Director of the Institute for Cryptoeconomics at the Vienna University of Economics, the only one who might actually lose her PhD because of this)

As long as the general public does not care nothing will change.
