The mechanics.
WHAT MOST PEOPLE DO
Read material repeatedly until it feels familiar.
WHY THAT FAILS
Familiarity is not knowledge.
Recognising something when you see it is different from recalling it when you need it.
WHAT ACTUALLY BUILDS KNOWLEDGE
Retrieving information from memory, repeatedly, with effort.
WHAT THAT MEANS PRACTICALLY
Close the book and try to recall it.
WHY THAT WORKS
Each retrieval strengthens the memory far more than each reading.
WHAT ELSE MATTERS
- Spacing: returning to material after intervals rather than all at once
- Mixing: alternating between topics rather than blocking them
- Explaining: putting it in your own words
WHY SPACING WORKS
Forgetting slightly, then recovering, strengthens memory more than immediate repetition.
WHAT FEELS WORSE AND WORKS BETTER
All of the above.
WHY THAT MATTERS
Methods that feel productive are frequently the least effective.
WHAT FEELS PRODUCTIVE AND IS NOT
Rereading Highlighting Copying notes
WHAT TO ADOPT INSTEAD
Testing yourself, from memory, at intervals.
