Experimental design of passive information experiment.
Multiple and single message groups receive the same content, except that the former receives it in two smaller pieces. The “first half content” and “second half content” together are exactly the same as “all content” received by the single message cohort.

Passive information survey results.
Pre- and post-survey means by cohort (standard deviation below), within cohort change in mean survey score (standard deviation below), and pairwise difference in the within cohort change between cohorts. For binomial variables the proportion responding ‘yes’ or the change in proportion of ‘yes’ responses. Index variables show Cronbach’s alpha in ().

Pre- and post-survey means and standard deviations, change between surveys, and Cohen’s d measure of effect size. For binomial variables, the proportion responding no/yes and change between proportions responding yes are shown. Index variables show Cronbach’s alpha in ().
