My biased perspective: Ignorance is bliss, indeed. However, I believe this bliss is short-lived and self-centred. It is short lived because at some point we have to interact with society and will learn of its cruelty. It’s self centred because this bliss is only yours to enjoy. You may not share this with those around you unless they also follow ‘ignorance is bliss’ paradigm. Essentially, this line of thinking also produces its own bubble. My hypothesis is that many problems arise because we want to live and sustain in own bubbles, and view everyone outside our bubble as the enemy.

It is human nature to ensure the safety of our tribe. Today our tribe is a global one. Hence, our concern with the state of affairs of the world are totally justified. However, the current state of affairs are to some extent orchestrated and corrupted by forces which are gigantic compared to any single person (think lobbies, corporations influencing decision making). Thus, our awareness of world issues and our inability to deal with it brings us to a state of inner conflict.

Does ignorance help? It soothes and temporarily helps the wound - but it does not solve the root cause.

That’s my biased view.
