Information vs. Knowledge — Deutsch’s Test


"Knowledge is a species of information, but not all information is knowledge, because it does not have causal power. It cannot propagate." — David Deutsch, Oxford Physicist

My "Plain English" simplification

Information becomes knowledge when it can be followed by a meaningful and accurate “because,” and has the potential to be shared in a way that lets others use and build on it.

Further Simplification (ultra-brief takeaway)

Knowledge = information + meaningful, accurate “because” + potential to spread.

My Bite-Sized Simplification

Information becomes knowledge when it can be followed by a meaningful “because.”

Quick Examples

Quick Test

Ask: If I say “because…” after this statement, does the rest make sense, is it accurate, and could I pass it on so others can use it?
