Methodology
How BuyVeto scores product risk.
How BuyVeto calculates Veto Scores, verdicts, confidence labels, evidence, and lower-risk reviewed alternatives without private user data.
Method receipt
The score has to clear four gates.
Applied proof: open the Apple AirPods Pro reviewed scorecard to see the same gates applied to a real product.
BuyVeto shows a final Veto Score only when the product identity, reviewed evidence, source dates, and deterministic component math are attached. Otherwise the result stays an unscored quick check.
Fixed verdict bands
The 0-100 score maps to fixed Buy, Caveat, Wait, Risky Buy, and Veto thresholds.
Reviewed evidence gate
Final scores need structured evidence, source dates, and a stable product identity.
Deterministic math
Component scores use fixed weights and the same weighted-average formula every time.
No private data
No receipts, bills, IDs, addresses, payment data, private documents, or account login.
What the Veto Score means
Veto Score is a deterministic risk score from 0 to 100. Lower scores mean fewer buying caveats. Higher scores mean stronger reason to wait, compare alternatives, or veto the product.
Verdict thresholds are fixed and deterministic. A cheaper checkout price or urgency claim does not move a product into a lower-risk band by itself.
Buy
0-24Lowest reviewed buying risk. Confirm seller terms, fit, and total price.
Buy With Caveat
25-49Reasonable only if the named caveat does not matter for your use case.
Wait
50-69Slow down, compare alternatives, or wait for better terms and evidence.
Risky Buy
70-84Buy only with strong return, warranty, support, or price protection.
Veto
85-100Skip unless new reviewed evidence changes the core risk.
How to read a result
Reviewed product
A final score appears only when BuyVeto has structured evidence, component ratings, and a stable product identity.
Quick check
A new public link can produce a useful buyer checklist, but it stays unscored until reviewed evidence exists.
Next move
Each reviewed verdict should point to an action: buy with terms checked, compare, wait, or skip.
Confidence label
Useful reviewed evidence supports this result; some buyer-specific checks still matter. Confidence is not a product-quality promise or fit guarantee.
Signals in the model
The default weighted components are complaint pattern severity, durability and reliability risk, hidden-cost risk, warranty and return risk, review trust risk, price fairness risk, and alternative pressure.
Reviewed pages use structured score components and clearly labeled evidence cards. Preliminary pages created from new links stay unscored until review. BuyVeto does not scrape retailers or depend on external product APIs in this slice.

10%Score math receipt
The Veto Score is a weighted average of reviewed component scores. Each component is scored from 0 to 100, multiplied by its fixed weight, added together, divided by the total weight, and rounded to the nearest whole score.
Formula
round(sum(component score x component weight) / total weight)
Weights sum
100 total weight points. The default methodology stays normalized before a verdict threshold is applied.
Example output
The example component set below produces a Veto Score of 54/100.
Complaint Pattern Severity
80/10020% weight contributes 16.0 score points in the example.
Durability and Reliability Risk
70/10015% weight contributes 10.5 score points in the example.
Hidden-Cost Risk
60/10015% weight contributes 9.0 score points in the example.
Warranty and Return Risk
50/10015% weight contributes 7.5 score points in the example.
Review Trust Risk
40/10015% weight contributes 6.0 score points in the example.
Price Fairness Risk
30/10010% weight contributes 3.0 score points in the example.
Alternative Pressure
20/10010% weight contributes 2.0 score points in the example.
Language guardrails
BuyVeto uses measured buying-risk language such as review trust risk, hidden-cost risk, marketing overreach, return friction, and support complaint pattern. It avoids defamatory claims unless an explicit verified source supports them.
Privacy and monetization guardrails
BuyVeto works from public product links and reviewed evidence. It does not request receipts, bills, IDs, payment data, addresses, private documents, or retailer login access.
Offers, affiliate links, and sponsored placements must stay labeled near the action surface. Read the disclosures and privacy policy.
