Dunning–Kruger effect is a cognitive bias in which people of low ability have illusory superiority and mistakenly assess their cognitive ability as greater than it is. The cognitive bias of illusory superiority comes from the inability of low-ability people to recognize their lack of ability.

Trump has a very unrealistic view of his ability to master all subject. 1. He is the only one that can fix our economy. 2. He is the only one that can make trade deals. 3. He is the only one that is able to negotiate with China, Russia, and North Korea. 4. He knows more than his experienced diplomats. 5. He knows more about foreign affairs.6. He knows more than his generals. 7. He knows more than his security team. Trump is a jack of all trades, and is the master of NONE. The repub TROLLS also suffer from this effect. The fact of the matter is that, they don't know it.
