We only know what we know when we need to know it.
Human knowledge is deeply contextual and requires stimulus for recall...
Small verbal or nonverbal clues can provide those ah-ha moments when a memory or series of memories are suddenly recalled, in context to enable us to act.
-- Dave Snowden, Founder & Chief Scientific Officer - Cognitive Edge
Source of information:
As we requires stimulus for recall, whatever we learn become whatever we remembered or whatever we can apply at the time when we link it with something we find it interesting, useful or important.
The ah-ha moment when a memory or series of memories are suddenly recalled usually happen when we need to solve a problem that enable us to act.
Nevertheless, if we do not learn the things first, we have no database to link or recall and the ah-ha moment will not be possible!
No learning is of minus value as you can only make it valuable when you master it and apply it!
