It’s more so related to power. Once you’ve acquired enough power, it consumes most people. They don’t like having their power challenged or put in a weakened state. Many of these people are acquiring power via some form or their “genius”. Technical wunderkind, military strategy genius, etc. So that drives their ego. But, they probably know they’re not actually a genius and plenty of people could have done what they did but they got lucky. So they end up getting defensive and insecure when anything challenges their power, risks to expose their genius as a fraud, etc. They’re operating on a mental house of cards and are volatile due to it. For regular people, they seem to be triggered by small things like losing a card game but it’s probably just that, a trigger that unleashed a wave of pent up insecurity.
