Participants 
We recruited 173 participants (85 female, 88 male, Mage ¼ 37.00 years, SDage ¼ 13.92 years) for US$0.50 on MTurk. Participants were randomly assigned to a 2 (stigma: high, low) 2(suffering intensity: high, low) between-subjects design. Power analysis using G*Power 3.1 revealed that to find a comparable stigma effect to the pilot study (d ¼ .37) with 80% power and a one-tailed probability of .05, the required sample size is n ¼ 184.
