The Super-chicken model refers to a manner of team recruitment that favors bringing together highly driven overachievers. It is argued that this can be counterproductive because of the negative effects of hyper-competitiveness on a group's dynamic, and that recruitment that emphasizes collaboration over individual excellence can result in greater productivity.[1] The name makes analogy to the interactions among chickens observed in a study by Purdue University evolutionary biologist William Muir.[2]
