 Finally, the model depicts normative motivation as intrinsic in the usual sense that people comply with norms as ultimate ends, or for their own sake. Sripada and Stich suggest that intrinsic motivation helps explain a property of norms they call “independent normativity”. This marks the fact that norms can exert reliable influence on people’s behavior even when those norms are not written down or formally articulated in any formal institution, and thus not enforced via any official mechanisms of punishment and reward (also see Davidson &amp; Kelly 2020). They also discuss motivation and independent normativity in terms of an “internalization hypothesis” drawn from sociology and anthropology, and suggest that the idea of internalization can be interpreted in terms of their model. On this story, a person has internalized a norm when it has been acquired by and represented in her norm database. The internalization hypothesis can then be construed as a claim that internalized norms are intrinsically motivating for the simple reason that it is a fundamental psychological feature of normative psychology that once a norm has been acquired, delivered to, and represented in a person’s norm database, the norm system automatically confers this distinctive motivational profile on the norm. Being accompanied by self- and other-directed intrinsic motivation is part of the functional role a rule comes to occupy once it is represented in the database of a person’s norm system—when it is “internalized”—in something analogous to the way that being accompanied by avoidance motivation and contamination sensitivity is part of the functional role a cue comes to occupy once it is represented in a person’s disgust system (Kelly 2011; also see Gavrilets &amp; Richerson 2017 for a computational model exploring the evolution of norm internalization and the kinds of selective forces that may have given normative psychology this intriguing characteristic).
