It is harder for an intelligent mind to blissfully be.
Processing all that is.... becomes a heavy weight. Misunderstood is commonplace.
The masses are not cursed with the ability to decipher the layers of reality therefore, a genius is perceived as Insane.
Have you ever entertained the notion that maybe all those committed to institutions actually were the only ones that had a clue?

Maybe the "crazy guy" yelling into the air downtown is refusing to obey the
voices of the powers that be. (No, silly! I do not hear voices. I wish I did sometimes. Maybe they could give me a clue.) God only spoke to the world 2000 + years ago? If Noah's began 50 years ago building an Ark.... he'd either be committed or outcast. If even just a few of the contributors of the Bible were submitting their stories today.... they'd be publically shamed and discredited. Maybe the earthbound with power could saturate them with poison and blow them up....

...but I digress. It seems to me that genius often turns to alteration of mood. "Head change"
There is most definately validity in the saying "Ignorance is bliss".
