  • Fig. 1 Complier average causal effects on transgender tolerance scale.

    The 95% confidence intervals surround point estimates; the thicker lines represent one standard error. Both transgender and nontransgender canvassers produced large and lasting increases in tolerance.

  • Fig. 2 Support for nondiscrimination law by survey wave.

    (A) Condition means. (B) Differences between these means. The 95% confidence intervals surround point estimates; the thicker lines represent one standard error. Standard errors are adjusted for clustering and pretreatment covariates. Defining “transgender” in the item wording revealed that placebo subjects were less supportive of protecting this group (P < 0.05, one-tailed). Next, all subjects were less supportive after viewing an opposing ad, but the effect of the conversations endured (P < 0.05, one-tailed). However, the ads’ impact dissipated, whereas the conversations’ effect endured (P < 0.05, one-tailed).
