Figure 1. Lay sentiments about pragmatic randomised controlled trials (pRCTs). (A) Mean appropriateness ratings, on a 1–5 scale, with standard errors, for intervention A, intervention B, the highest-rated intervention, the average intervention, the lowest-rated intervention and the A/B test. Circles represent measures directly collected from participants. Triangles represent averages derived from the direct measures. The distance of the mean appropriateness of the lowest-rated intervention (brown triangle) minus the mean appropriateness of the A/B test (orange circle) represents experiment aversion. The distance of the mean appropriateness of the average intervention (gray triangle) minus the mean appropriateness of the A/B test (orange circle) represents the A/B effect. The distance of the mean appropriateness of the A/B test (orange circle) minus the mean appropriateness of the highest-rated intervention (purple triangle) represents experiment appreciation. (B) Appropriateness ratings transformed into percentages and standard errors of participants objecting (defined as assigning a rating of 1 or 2—‘very inappropriate’ or ‘somewhat inappropriate’— on a 1–5 scale) to implementing intervention A, intervention B and the A/B test.
