2D:4D Ratio And Psychological Traits: Results From The LW/SSC Survey Sample
Read the original on Slate Star Codex →
Summary
Survey-analysis testing 2D:4D digit-ratio claims on the 2014 LW + SSC surveys (n=529). The BASIC finding failed -- no significant male/female digit-ratio difference, and the whole sample was implausibly 'feminized' (Scott suspects measurement error). Yet two clear signals emerged: digit ratio correlated with opinion-of-feminism in men and with Bem masculinity in women (both low p). Honest 'this was weird / this study was a mess' conclusion, blaming low sample size + measurement error for the inconsistencies. Tests-and-largely-fails-to-replicate the digit-ratio literature rather than relying on it, so no replication caveat (and the field is flagged by Scott himself as 'maddeningly inconsistent').
Why this score
Quality 60 · Strong. A competent, honest, data-driven survey-analysis, but a messy, inconclusive result with unexplained signals -- modest in insight/value. Solid.
Claude’s paradigm shift 35 · Slight. Slight. An empirical test of existing claims; little new framing.
Real-world impact 2 · Minor. A competent, honest survey-analysis of digit-ratio claims that largely failed to replicate; a messy, inconclusive data exercise within the discourse, no material-world reach → RWI 2.
