From the article,

    What can we learn about what other people are thinking, about their mental models of the world, by paying very careful attention to the words they use?

A lot of people will make fun of you, but I think everyone should read a book or two that's not airport pulp.

Given you're on HN, try Gödel, Escher, Bach. https://www.amazon.com/G%C3%B6del-Escher-Bach-Eternal-Golden...

Be warned though, it'll take you well over a decade.
