 Another line of research suggests that key to understanding the roots of human normativity is the fact that human children are overimitators. They are not just spontaneous, intuitive, and excellent imitators, but they also tend to copy all of the elements in the sequence of a model’s behavior, even when they recognize some of those elements are superfluous to the task at hand (Lyons, Young, &amp; Keil 2007; Kenward, Karlsson, &amp; Persson 2011; Keupp, Behne, &amp; Rakoczy 2013; Nielsen, Kapitány, &amp; Elkins 2014, cf. Heyes 2018: chapter 6). Children attend to the specific manner in which an action is carried out rather than merely to the goal it is aimed at, and conform to the full script even if they see that the goal can be achieved in some more direct way. Moreover, children monitor others to see if they are doing likewise, and enforce overimitation on their peers by criticizing those who fail to perform the entire sequence of steps (Kenward 2012; Rakoczy &amp; Schmidt 2013). Overimitation can lead to the unnecessary expenditure of energy on these extraneous behaviors, but the trait may be an adaptation nevertheless. According to this argument, the costs of what look like individual “mistakes” are ultimately outweighed by the communal benefits generated by a population whose individual capacities for transmitting norms and other cultural variants are more insistent in this way, erring on the side of too much imitation rather than too little (J. Henrich 2015: chapter 7). Whatever it was initially selected for, researchers have suggested that the psychological machinery responsible for overimitation makes important contributions to normative cognition. Evidence indicates that this machinery generates strong (perhaps intrinsic) social motivation aimed at behavioral conformity with others. When working in conjunction with a norm system, this source of motivation may also help facilitate performance of the key task of keeping an individual’s behavior compliant, inducing her to conform not just to behaviors she is observing but to those norms she has internalized (Hoehl et al. 2019 for overview).
