In the field of psychology, the Dunning–Kruger effect is a cognitive bias wherein people 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.. In "direct translation": They're indeed not able to notice how ridiculous they appear to the other people (especially because all this showing-off mostly is in no comprehensible relation with their actual abilities)
