Methods & evidenceCommercial Ad Platform Algorithmic Randomization ImbalanceA joint statistical test of baseline covariates rejected balance across treatment groups (p = 0.00), showing significant baseline differences for gender (-0.03 female diff, p < 0.01) and age (+0.03 old diff, p < 0.01), requiring normalized difference robustness re-estimation.RCTEconomics (general)Professional Stigma vs. Social Stigma Behavioral DifferentiationProfessional stigma framing decreased sign-ups by 0.032 percentage points (26% relative drop from 0.121% control baseline), while social stigma framing decreased sign-ups by 0.047 percentage points (39% relative drop).
