So stupid, it actually hurts
Have you ever noticed how intelligent people are mostly keeping quiet, evaluating their every word before leaving their mouths, not wanting to give out wrong information?
Stupid people don’t have such a problem. They are capable of spewing enormous amounts of stupid stuff per minute. And they are not shy at all. There are actualy some studies on this matter, showing that the less skilled you are, the more you think highly of your intellect. This became known as the Dunning-Kruger effect. Sadly, we live in a world where intellectually challenged people speak, and smart people are quiet.
