Twitter will suggest that you listen to people who listen to each other. Amazon will suggest that you read something very much like what you just read. Even your search engine will try to make sure that you get results that are similar to the ones you clicked on last time. If you go with the flow, you’ll end up hearing the same narrow view recycled repeatedly – yet you’ll think you did your due diligence.
Don’t fool yourself.
Gather information from those who do not communicate with one another. In fact, you want to gather information from entire networks that do not communicate with one another. Truly rich and diverse information comes only when you hear, separately and independently, from “worlds” that do not overlap: from different parts of the earth, different economic sectors, different social demographics, different religions, languages, ideologies and cultures.
