Der Denkfehler so vieler Leute, von Ezra Klein bis Sam Harris: "Die Leute wählen rechtsradikal, dann müssen wir halt alle etwas rechtsradikaler werden, um den Status Quo halbwegs zu konservieren."
Gewählt wird meist aber nicht FÜR Rechtsradikalismus, sondern in erster Linie GEGEN den Status Quo.

Math has publication fraud, too.
For a long time, mathematicians thought that as long as they keep away from predatory journals or paper mills, the problem does not affect them. This turned out to be wrong.

America's captains of industry already behave as if the country were a dictatorship, so why would they be more likely to oppose the government if that government can imprison them? The CEOs won't save democracy. If anything, they'll sponsor its destruction

In geometry we call something 'generic' if there is nothing special about the situation. E.g, 3 generic points in the plane don't lie on a single straight line.
If you prove a theorem for the generic situation, you have proved it in a special case only because you disregarded the special cases. 🤯
