Nuts and dilemmas: A research note

Dilemmas have been modeled in many systems; the present study addressed human groups in an empirical comparison of Nuts and n‐PD, two commons dilemma games. Results of a repeated measures design indicated similarity in first‐period choices but less cooperation in n‐PD play across periods. Results also substantiated predictions for the effect of individualistic or group‐oriented instructions and for the probability of n‐PD game continuation.
