I think you're mixing up "psychosis" with fads, trends, or perhaps executive excuses to do layoffs.

A feature of psychosis is being unable to distinguish between external ideas and internal ones. For example, if a brown-nosing Yes-Man machine keeps reflecting your own leading questions back at you, laundering them into "independent" wisdom.

In contrast, I'm pretty sure COVID and the invasion of Ukraine are actual external phenomena that affect businesses and economies.

The lists of who's, what's, why's, and when's always change but when the decades pass it's never one narrow type of people or the "not me's" which are gullible - it's just human nature + regional timing. The targeted groups are the only ones who are really easy to break out.
