I discuss recent findings from behavioral economic experiments in the lab and in the field on the role of leaders in human cooperation. Three implications for leadership are derived, which are summarized under the notion CC strategy. Firstly, leaders need to trust to not demotivate the motivated. Secondly, leaders need to punish to motivate the non-motivated. Finally, leaders shall (and can) attract motivated types. The discussion is embedded in a more general attempt to promote and stimulate interdisciplinary exchange of both methods and ideas in leadership research.
