three experiments (N = 1,993): in a preliminary experiment, we vary the payoffs over a large range. In our first main … experiment (Study 1), we present a novel design that varies payoffs orthogonally in a within-subjects design. Our second main … experiment, Study 2, investigates the orthogonal variation of payoffs in a between-subjects design. In a complementary analysis …
