Donations in the intermediation task, donors’ beliefs about the share intermediaries pass on, and their ethical preferences. (a) Plots donors’ donations in the intermediation task against their beliefs about how much intermediaries pass on, each donor corresponding to one bubble. The size of each bubble depicts the donor’s Kohlberg class 5 score. The lighter bubbles are shaded, and the larger the bubble, the larger the Kohlberg 5 score. The blue line plots a Kernel regression of amounts donated on donors’ beliefs about how much intermediaries pass on. (b) Plots donations against donor beliefs along with their Kohlberg class six scores.
