Fig. 1. Age predicts greater distancing and charitable donations, but increased preference for national over international charities.
a,b, In both subsample 1 (S1, left) and subsample 2 (S2, right), older age predicted higher rates of distancing (a) and hypothetical charitable donations (b) when summed across both charities. The relationship between age and total donations is quadratic. c, When taking into account charity location, age was positively associated with national donations but negatively associated with international donations. Lines show fitted linear models; shaded areas show 95% CIs; circles show individual data points.
