Watch for
Cramming because it feels productive in the moment despite poor long-term retention.

Spacing Effect
Spaced practice beats cramming.
The phenomenon where learning and retention are significantly better when study sessions are spaced out over time rather than concentrated in a single session.
Why it matters: One of the most robust findings in cognitive psychology. The basis of spaced repetition systems like Anki.
Try this
Distribute learning across multiple sessions with increasing intervals between them.
Real-world example
Studying a language for 20 minutes daily over two weeks produces better retention than studying for five hours in one day.
Key researchers
Hermann Ebbinghaus
First described in 1885
Psychological mechanism
Forgetting and reconsolidation. Each time a memory is recalled after partial forgetting the brain strengthens the neural pathway. Spaced practice forces repeated retrieval from long-term memory which strengthens the trace.
Seminal research
Hermann Ebbinghaus (1885) memory research demonstrating the spacing effect in his seminal work on forgetting curves.

Debrief
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.
