The examples the tweeter gave like 'reading' as just really poor substitutes for travel, especially if you're a white, English-speaking, west-coast person like the tweeter. Reading the opinion column of the New York Times will probably close their minds further than open it up.

Hanging out with other people who are wealthy/liberal enough to make it to and live in San Francisco will also do the same. Amplify the echo chamber rather than break it down.

I grew up in India and the Middle East in a very different sociocultural background with different values than the west coast, liberal, tech-elite culture I live in now and I find many of the people around me now have a much narrower world-view despite their education and 'reading'.
