R4 — Ask about recent, distinctive events — not vague aggregates

Rule: Frame retrieval questions around recent, distinctive events. Do NOT ask vague-lifetime or aggregate-frequency questions.

Why: Recall literature (Tourangeau, Rips & Rasinski (2000) — the four-stage response model) — accuracy depends on event properties: recent + significant + distinctive events are recalled far more accurately than distant, routine, or vague ones. Junco 2013 (Junco 2013 — Facebook self-report overstates logged use by ~5.6x) shows ~5.6x overstatement when respondents must aggregate over recall.

How to apply: Ask "When was your most recent review?" (specific, distinctive) NOT "How often do you get reviews?" (vague aggregate). Ask "When did you last update content?" NOT "How frequently do you post?"
