Note: Models 1 and 2 are ordered logit regressions using 5-point dependent variables. Model 3 is a multinomial logit and the “unsure/don’t know” response serves as the omitted baseline category. Table reports regression coefficients with standard errors in parentheses. All significance tests are two-tailed. ** p < 0.01, * p < 0.05.
