This is a Lexicon entry: the mechanism, when it shows up, and the countermeasure. The full correction, with real-world cases and the audit prompt, hasn't been written yet.
Definition
The evolutionary tendency to focus on and remember negative information more intensely than positive information. One criticism stings more than ten compliments soothe.
When it shows up
Reading reviews or feedback (one bad comment overshadows ten good). After a social interaction (remembering the one awkward moment, not the easy ones). End-of-year reviews of your own life. Modern context: A SaaS product receives 47 five-star reviews and 3 one-star reviews in a week. The founder reads all three one-star reviews twice each and implements a product change based on them - without checking whether the complaint pattern appears in the five-star cohort. High-stakes instance: Media consumption and political polarisation - documented negativity bias in news selection and sharing produces systematic overrepresentation of threat, conflict and decline narratives relative to their actual frequency in events. Failure mode: Negative information is stored more vividly, retrieved faster and weighted more heavily than equivalent positive information. The mental ledger is kept in a currency where bad units are worth more than good ones, skewing every subsequent judgment. Estimated cost: High - often irreversible where this bias dominates unchecked decisions.

Countermeasure
Deliberately count positives in equivalent detail to negatives. If you can name five specific things that went wrong today, name five specific things that went right at the same granularity. Equalize the resolution of the tally. When correction costs more than the bias: In genuinely high-stakes irreversible situations: negativity bias is an adaptive alarm system. Its overactivity in safe modern environments is the problem - not its existence. In contexts with real irreversible downside (physical safety, major financial commitments, health decisions), heightened sensitivity to negative outcomes is appropriate.
