Reviewer E. G. Leigh Jr. describes SuperCooperators as “a must for evolution teachers”: “It emphasizes human cooperation more than the wonders of nature, but in today’s world, that emphasis may make it a more effective teaching tool. Moreover, its message on cooperation’s essential role in evolution and human affairs is right on target.” Praising it for sounding “like an autobiographical fireside chat, in which Nowak celebrates his mentors … who helped him learn to shape mathematical questions about when cooperation evolves,” Leigh faults it mildly for its occasional lack of clarity and for its deprecation of kin selection.
