The Dunning-Kruger effect maintains that people who know very little about a subject can often think of themselves as experts because they don’t know enough to realise how little they actually know, while people who are very knowledgeable about a subject think they’re amateurs because they understand there’s so much more to learn.

One group will be offering their opinion to everyone who’ll listen while the other group is largely silent because they’re busy trying to learn what they don’t know. I’ll leave it up to you to decide which group is silent.
I’ll leave you with a very famous quote that epitomizes the Dunning-Kruger effect and that is.
“The fundamental cause of trouble in the modern world today is that the stupid are cocksure while the intelligent are full of doubt.” -Bertrand Russell.
