What if the root cause is that because we stopped labeling villains, they no longer fear being labeled as such. The consequences for the average lying academic have never been lower (in fact they usually don’t get caught and benefit from their lie).
Unfortunately academia as a pursuit has never had a larger headcount and the incentives to engage in misconduct have likely never been higher (and appear to be steadily increasing).
Surely the public discourse over the past decades has been steadily moving from substantive towards labeling each other villains, not the other way around.
When the opposition is called evil it's not because logic dictates it must be evil, it's called evil for the same reason it's called ugly, unintelligent, weak, cowardly and every other sort of derogatory adjective under the sun.
These accusations have little to do with how often people consider others things such as "ugly" or "weak", it's just signaling.
