# Product Behavior and Economics Review ## Outcome Produce decision input. Connect mechanisms to product expression, economics, evidence, failure modes, and falsifiable tests. Match the user's language. ## Intake and mode Infer the decision, actors, outcomes, behavior, cadence, constraints, and evidence. Ask only if an answer could reverse the review; otherwise label assumptions. Use `grilling` only when explicitly requested. Choose focused, flow/page, or full-system mode. ## Load only relevant modules - Psychology, cognition, motivation, social behavior: [behavior](references/behavior-psychology.md) - Growth, conversion, habits, retention: [engagement](references/growth-engagement.md) - Opportunity cost, marginal analysis, incentives, externalities: [economics](references/economics-fundamentals.md) - Pricing, packaging, paywalls, willingness to pay: [pricing](references/behavioral-pricing.md) - Marketplaces, network effects, multi-homing, subsidies: [platforms](references/platform-economics.md) - Direction, resource allocation, strategic trade-offs: [strategy](references/strategy-quality.md) - Children, vulnerable users, dark patterns, wellbeing: [welfare](references/welfare-ethics.md) - Precise claims or literature: [sources](references/foundations-and-sources.md) For substantial reviews, read [the full protocol](references/review-protocol.md). Add welfare when vulnerability or manipulation is plausible. ## Core protocol 1. Frame actors, value exchange, outcomes, conflicts, and assumptions. 2. Separate facts, claims, theory-based inferences, product hypotheses, and unknowns; state confidence and boundaries. 3. Build `context -> mechanism -> behavior -> product expression -> outcome -> harm -> evidence`; missing links stay hypotheses. 4. Check segments, repetition, incentives, gaming, externalities, opportunity cost, and reversibility. 5. Propose the smallest falsification test: outcome, counter-metric, segment, window, decision rule. ## Output and welfare boundary Lead with the decision frame and 3–5 material findings, then implications, trade-offs, gaps, and tests. Review-only requests get options; recommendations stay conditional. Do not optimize compulsion, deception, coercion, false scarcity, hidden cost, or obstructed exit. Never operationalize addictive mechanics for vulnerable users; reframe toward outcomes, autonomy, trust, and harm counter-metrics. `evals/` holds fixtures; `reports/` holds scorecards. Fixtures are regression evidence, not independent model or human-review evidence.
