On Avoiding Groupthink

Friend's FB:

"Every time I read some acquaintances' fb posts, I cringe at how bigoted they sound and I feel that i should delete or at least silence them on fb.

But I stopped myself today cos I realised they are in their own echo chambers cos their friends are mostly likeminded and agree with them.

I conclude that each day I should see some stuff on my feed that makes me cringe. This daily uncomfortable feeling lets me know that my way of thinking is not the only one out there."
