  1. In the correlation analysis between income and other variables, participants who chose the answer “I prefer not to answer this question” were excluded, leading to N = 142. All other analyses had N = 161. None of the results reached Bonferroni adjusted alpha of .001. These results held after controlling for age, education level, income, and political orientation.
