Fig. 4: Generosity during and after mass gathering attendance.
From: Prosocial correlates of transformative experiences at secular multi-day mass gatherings
A The relationship between days onsite and generosity; B–D The relationship between transformative experience and generosity during (n = 785), immediately following (n = 1810), and 6 months following (n = 405) attendance. Generosity was assessed by providing participants with 10 tickets that would be redeemable for valuable prizes. Participants were given the opportunity to keep as many tickets as they wanted for themselves and give the rest to a randomly selected stranger. Lines show estimated marginal effects using multilevel linear models controlling for incidental variables with event set as a random factor (see analytic approach); significance values based on independently run two-sided t-tests on the resulting coefficients. Ribbons indicate 95% confidence intervals. Dashed blue lines reflect the expected level of generosity based on a published meta-analysis of Dictator games 56 (n = 616 data points). ns not significant. **p = 0.001; *p = 0.012.
