This is basically critical thinking. Which is also my goal for (optimal) education: To build a society of people who think for themselves, critical thinkers; those who do not take everything for granted. The skeptics.

See also Nassim Nicolas Taleb's advice to focus on what you DON'T know rather than what you DO know.

Related to syntopical reading/learning as well. (and Charlie Munger's advice). You want to build a complete picture with a broad understanding and nuanced before formulating an opinion.

Remove bias from your judgement (especially when it comes to people or civilizations) and instead base it on logic and deep understanding.

This also relates to (national, but even local) media... How do you know that what the media portrays about something or someone is correct? Don't take it for granted, especially if it is important, and do your own research. Validity of source is important; media is often opinionized and can contain a lot of misinformation.

See also Simone Weil's thoughts on media, especially where she says misinformation spread must be stopped. It is a vital need for the soul to be presented with (factual) truth.

Is Syntopical Reading not the same as meta-analytic research? In what ways does it differ? In what ways is it the same?
