Behavioural type clusters and their conditional contributions in Wave 2. Note: EC, empirical cooperator; SNC, social norm cooperator; NC, normative cooperator; U, unconditional; TD, threshold-driven. Empirical (Normative) Expectations Influence is calculated by taking the difference in conditional contributions for High and Low EE (NE) averaged for when NE (EE) are high and low. Low EE (NE) refers to the hypothetical situation that the majority of the group contributes (thinks one should contribute) less than 50 points. High EE (NE) refers to the hypothetical situation that the majority of the group contributes (thinks one should contribute) at least 50 points.
