Table 1 Main effect of highlighting scientific consensus on dependent variables

From: Highlighting consensus among medical scientists increases public support for vaccines: evidence from a randomized experiment

Dependent variables Mean consensus treatments Mean control group Cohen’s D
(n = 163) (n = 43)
Perceived scientific agreement 89.80 *** (0.52) 83.93 (2.65) 0.60
Endorsement autism-vaccine link 2.15 *** (0.12) 3.07 (0.34) 0.55
Risk perception 2.93 *** (0.14) 3.51 (0.35) 0.31
Public support/attitudes 6.21 *** (0.09) 5.66 (0.24) 0.44
  1. Note: Standard errors in parentheses. All mean comparisons significant at *** p < 0.01 (bold face). Unequal variances assumed. Cohen’s D is a standardized measure of effect size. Values between 0.3 and 0.6 are generally considered to be “moderate” effect-sizes in behavioral science [25]
