Two findings:\n\n- **\"Increasing the strength of social influence increased both inequality and unpredictability of success.\"** When people could see others' choices, the winners ran further away from the pack — and which song would win became *less* predictable from quality alone.\n- **\"Success was also only partly determined by quality.\"** Quality matters; social-influence dynamics dominate the rest.\n\nImplication for a new site: when reviews are absent, the \"rich get richer\" social-influence dynamic that helps incumbents is **unavailable** — making first-impression design and clarity carry disproportionate weight ([[stanford-web-credibility-fogg-2002-46pct-design-look]]).\n\n**Source:** Salganik, M. J., Dodds, P. S., & Watts, D. J. (2006). \"Experimental Study of Inequality and Unpredictability in an Artificial Cultural Market.\" *Science* 311(5762):854–856.\n\n**Confidence:** Verified. Large-N controlled experiment in a peer-reviewed venue.\n\n**Caveat:** The study models **cumulative-advantage** dynamics — not a per-site conversion lift. Use it for the **structural** point (\"social proof produces winner-take-most dynamics, and a new site is excluded from those dynamics by definition\"), not for a quantitative prediction.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"new-site-no-reviews-design-substitutes","title":"New-site no-reviews condition — when social proof is absent, first-impression design + clarity + transparency + working functionality do the heavy lifting (NN/g + Fogg); \"a new site cannot convert without reviews\" is overstated","kind":"reference","scope":"business","link_type":"relates-to"}],"incoming":[{"slug":"research-brief-launch-wait-psychology-june-2026","title":"Research brief: the psychology of the launch-and-wait — owner patience and visitor first impressions on a brand-new website (June 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"visitor-side-mechanism-inventory","title":"Visitor-side mechanism inventory — seven cognitive mechanisms governing a first-time visitor's impression of a brand-new website (50ms first impression, halo effect, processing fluency, aesthetic-usability, Stanford credibility, trust cues real vs theater, social proof)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"cialdini-social-proof-influence","title":"Social proof — Cialdini, Influence: \"We view a behavior as more correct in a given situation to the degree that we see others performing it\"; under uncertainty, visible signals of others' choices shift decisions holding quality constant","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-06-25T16:10:59.267Z","updated_at":"2026-06-25T17:07:10.774Z"}
