Testing Effect

Long-term memory improves when you actively retrieve information from memory during learning, rather than just passively reviewing it.

What should be remembered Editing and reinforcing memories

The testing effect shows that actively recalling information strengthens memory more than re-reading or passive study. This happens because retrieval practice forces your brain to reconstruct knowledge, creating stronger neural pathways. For example, after reading a chapter, quizzing yourself on key concepts will help you remember them better than simply highlighting the text.

Would you catch it?

Recognising a definition is not the same skill as spotting it.

Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.

Scenario 1Which bias?

After a training workshop, Chen attempts to summarize the safety procedures from memory for a coworker.

Scenario 2Which bias?

After reading a dense report, Chris closes it and tries to explain the main findings to his partner in simple terms from memory.
