I recently listened to an interview with Isabel Wilkerson, author of Caste: The Origins of Our Discontents which is about America, but she spent years doing research including visiting other countries.

She tells an anecdote about visiting a conference in India on caste and even though the reason everyone was there was to discuss ways to undo the effects of the caste system, she was able to see effects of the system right there in the conference by how various participants interacted with each other. It was so ingrained to the participants that they didn’t realize they were doing it. It was small things like how one person would yield to another during conversation.

Interesting listen.
