Figure 1

The median amount of hypothetical money forgone to give $75 (USD) to another person at each social distance for the Observed (open triangles, top line), Anonymous (closed circles, middle line), and Standard (open squares, bottom line) groups. The solid lines are the best-fitting versions of Equation 1 with two free parameters (s = 1). The dashed line is the best-fitting version of Equation 1 for the Observed group with three free parameters.
