Yes. Well known, it’s in the Bible in Proverbs. Essentially the fool babbles everything, while the wise man keeps knowledge to himself.

One of the biggest reason this happens is because foolish people will always argue the truth/correct knowledge. And fools are brilliant at arguing, because they don’t worry about being correct, or logically consistent, and can never admit being wrong to anything. Of course women are the same, but all women are fools.

There is an interesting corollary to this, in that the larger group of people you have, generally the dumber they all become. This is also why higher education is a bastion of idiotic liberals, who all circle jerk each other on how smart they think they are.
