Canonical definition
Think cramming all night will help you remember? And then you forget everything the next day? That’s Lag Effect – information sticks better when learning is spread out over time instead of in one go.

Free cognitive-bias Agent Skill
Use Lag Effect as a focused cognitive-bias lens. Explain the pattern, check whether it plausibly fits the situation, surface an alternative non-bias explanation, and return a practical counter-check without diagnosing people or claiming causation.

Boundary
