Testing Effect
Testing yourself strengthens memory more than restudying.
The phenomenon where retrieving information from memory through testing produces greater long-term retention than passive restudying even without feedback.
Why it matters: Also called retrieval practice. One of the most effective learning strategies known.
Try this
Replace passive re-reading with active recall practice using flashcards or self-testing.
Real-world example
A student who takes practice quizzes retains more than one who re-reads the same material.

Psychological mechanism
Retrieval strengthens the memory trace and creates multiple recall pathways. The effort of pulling information from memory signals that this material is important requiring additional consolidation.

Biases are not character flaws. They are recurring patterns in how minds compress uncertainty, save energy, and narrate reality. Once you recognise the pattern, you can slow the decision down, test the assumption, and make space for a better explanation.
