The relevant class here isn’t people with acute psychosis. The relevant class is “their reasoning in general or on a specific issue has degenerated”, which a substantial portion of the population has due to various issues (politics being the classical example). Where they are strongly participating in motivated reasoning or other biases to a stronger degree than typical.
(So, while it may infact be rare for acute psychosis to occur, more mild versions that are still causing them to make far stronger statements than reasonable is more central to what I believe most people are referring to)
