Proportions of trials in which allocators chose to randomize, or allocate directly to one of the two potential recipients in the equal endowment conditions; or randomize, allocate directly to the relatively poorer recipient, or allocate directly to the relatively richer recipient in the unequal endowment conditions. Naïve standard errors, calculated as $\sqrt{\frac{p(1-p)}{N}}$, are reported in parentheses. t statistics from t tests comparing the different proportions to each other are reported in the lower panel of the tabel together with corresponding p values.
