How is this score calculated?
TinyNeeds uses a trust-adjusted, mention-weighted algorithm. Each source score is multiplied by its mention volume and a credibility multiplier before averaging. Retail platforms (Amazon, Walmart) receive a lower multiplier due to known positive-review incentive patterns. Editorial and test-bench sources (Wirecutter, Rtings, The Verge) and community platforms (Reddit) receive higher multipliers for their more rigorous or candid standards.
