 That said, behaviors that are perceived to be normal in a community are particularly salient to individuals’ norm psychology. Children are also normatively promiscuous in that they appear prone to false positives in the course of acquisition, seeing behavior as norm-guided even when it is merely common, and inferring the presence of normative rules when there are none. One series of studies found that when participants (children and adults from both the United States and China) detected or were told that a type of behavior was common among a group of people, they came to negatively evaluate group members who behaved in a non-conforming way (Roberts et al. 2018; Roberts, Ho, &amp; Gelman 2019). Researchers have investigated this feature of norm acquisition from different angles, and have labeled it with various names, including the “descriptive-to-prescriptive tendency” (Roberts, Gelman, &amp; Ho 2017) the “common is moral heuristic” (Lindström et al. 2017), and the “injunctive inference hypothesis” (Davis, Hennes, &amp; Raymond 2018, discussing, e.g., Schultz et al. 2007). Since the evidence suggests that human normative cognition invites an easy inference from the “is” of a perceived pattern of common behavior to the “ought” of a norm (Tworek &amp; Cimpian 2016), philosophers may be tempted to think of this as a “naturalistic fallacy bias”.
