> Now, do you not think that we have any relevant prevailing biases, created by our education, media, history, culture, economic system, and government? [1] Ones that are so deeply ingrained in our society, that we don't even notice them?

The difference is the key though. In the West we know that we are brainwashed at some level, because we can observe it happening around us with people who share different viewpoints or cultures.

However, in a country where there's only one discourse that is accepted, you can mistake your own brainwashing for the actual truth because nothing is out there to make you think otherwise.
