Expiring vs. Long-Term Knowledge
How much of what you read today will you still care about a year from now?
This is a concept I find useful to be mindful of what I’m consuming. There’s several articles about this idea — here’s excerpts from a great and short one
Expiring knowledge catches more attention than it should, for two reasons. One, there’s a lot of it, eager to buzz our short attention spans. Two, we chase it down, anxious to squeeze out insight before it loses relevance.
Long-term knowledge is harder to notice because it’s buried in books rather than blasted in headlines. But its benefit is huge. It’s not just that long-term knowledge rarely expires, letting you accumulate it over time. It’s that compounds over time. Expiring knowledge tells you what happened; long-term knowledge tells you why something happened and is likely to happen again. That “why” can translate and interact with stuff you know about other topics, which is where the compounding comes in.
