Point taken.
Although let’s be honest—you were only joking. We both know cursing doesn’t really make people smarter. And we know intuitively that cursing is not a meaningful measure of mental power.
Believe me, there are plenty of college students, and others among the targets of Hollywood producers, who will actually conclude in their minds, perhaps subconsciously, that cursing is somehow a benefit to them.
Busted. :)
But I will say this. Cursing is not a sign of intelligence, but is also NOT an indicator of non-intelligence. It's more of a cultural/environmental thing if you ask me. I've known some hardcore convicts/gangbangers/criminals that were VERY intelligent. Note: Intelligence and education are not that same thing.
Plus. I consider myself fairly intelligent and I curse like a sailor with tourrettes. :)
