Methods & evidenceFirst-Order Stochastic Dominance (FOSD) Communication PolarizationBusiness content and positive sentiment exhibit strong negative Pearson correlation ($\rho = -0.478$ at message level, $\rho = -0.480$ at entrepreneur level, $p < 0.01$). Kolmogorov-Smirnov FOSD test yields $p = 1.0$ for low sentiment dominating high sentiment in business content and $p = 0.0$ for the reverse, confirming strict inverse polarization.RCTLabour & employmentMulti-Dimensional Skill Portfolio Signaling44% of participants scored in the top performance band for at least one skill, while only 10% scored in the lower half across all skills; as a result, earnings for the certified group strictly stochastically dominated control earnings.RCT
