title: Is strong reciprocity really strong in the lab, let alone in the real world?
abstract: We argue that standard experiments supporting the existence of "strong reciprocity" do not represent many cooperative situations outside the laboratory. More representative experiments that incorporate "earned" rather than "windfall" wealth also do not provide evidence for the impact of strong reciprocity on cooperation in contemporary real-life situations or in evolutionary history, supporting the main conclusions of the target article.
