Dunning-Kruger effect 

In the field of psychology, the Dunning–Kruger effect is a cognitive bias wherein persons of low ability suffer from illusory superiority, mistakenly assessing their cognitive ability as greater than it is. The cognitive bias of illusory superiority derives from the metacognitive inability of low-ability persons to recognize their own ineptitude. Without the self-awareness of metacognition, low-ability people cannot objectively evaluate their actual competence or incompetence.

As described by David Dunning and Justin Kruger, the cognitive bias of illusory superiority results from an internal illusion in people of low ability and from an external misperception in people of high ability; that is, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others." Hence, the corollary to the Dunning–Kruger effect indicates that persons of high ability tend to underestimate their relative competence, and erroneously presume that tasks that are easy for them to perform also are easy for other people to perform.

Dunning-Kruger effect

When you accuse someone of suffering from the Dunning–Kruger effect in an online argument. You are committing a classic ad-hominem: You attack the person, claiming they lack intelligence to have a valid opinion. The argument itself is left untouched.

It is substituting rational thinking with quick emotion-based judgmental attitudes. Because it feels better attacking your opponent rather then engaging in clear rational thinking. You're just projecting your own insecurities onto your opponent.

Often goes hand-in-hand with credentialism.

Many zoomers are guilty of using this term in online arguments thinking they're very "smart" for referencing it. They learned about it from watching YouTube videos. It is very frustrating to deal with them having that mindset.

The Dunning-Kruger effect is about skill competence rather than intelligence.

“You’re a classic example of the Dunning–Kruger effect.”
If you are guilty of using Dunning-Kruger effect in online arguments, please stop & change your behavior. You're not contributing to anything positive to foster rational thinking.

If you are not guilty, then continue with what you're doing & don't make yourself susceptible to that behavior. Thank you for not being an asshole, make sure to avoid people that engage in that behavior.
