There is growing interest in understanding whether behavior is the same across locations. By holding cross- and within-country dimensions constant (in contrast to previous studies on cross-group comparisons of conditional cooperation), the authors investigated cooperative behavior between social groups in the same location. Their results reveal significantly different cooperation behavior, suggesting that different social groups exhibit differences both in terms of composition of types and extent of conditional cooperation.
