Table 1 Average marginal effects of gene drive attributes and respondent characteristics on support and FAQ selection.

Note: Drive support estimated using a partial proportional odds (PPO)–ordered logit regression model and the margins command in Stata with compressed ordinal scale of oppose, neutral, or support and SEs clustered by respondent in parentheses. FAQ selection estimated using ordinary least squares. Additional regression specifications for these dependent variables in tables S3 to S5. McFadden’s R2 reported for the PPO-ordered logit regression and standard R2 for least squares. Includes survey sampling weights. ***P < 1%, **P < 5%, and *P < 10%.
