Abstract

How do people think about what is appropriate, allowed, required, or forbidden? Heyes’s “cognitive gadgets” account of norm psychology proposes that cultural selection affects not just the content of norms but also how people think and feel about norms in general. Contra nativist views that paint human normativity as genetically inherited and evolving at a glacial pace, Heyes’s model suggests that people alive today have substantially more control over how future generations think about norms and their enforcement. Here, we explore one important implication of Heyes’s account: New technologies, such as social media, can spur rapid cultural evolution of normativity (Acerbi, 2019). Commentary plays a key role in the cultural transmission of norms by defining the terms of compliance and enforcement, and it is increasingly taking place online, with more than 4 billion social media users worldwide (Dixon, 2022). Building on recent studies of online normative discourse, we speculate how three features of social media shape the cultural evolution of normativity: hidden incentives, multiple audiences, and speed of transmission. By incentivizing particular types of commentary over others in ways that are not always transparent to users, social media can teach people new ways to think and feel about norms. For example, preliminary evidence suggests that social media incentivizes moral outrage. Because social media platforms profit more by keeping users online, their algorithms promote content that is most likely to be shared. Users are especially likely to share commentary containing moralized and emotional language (e.g., moral outrage) because it attracts attention and highlights group identity (Brady, Crockett, & Van Bavel, 2020; Brady et al., 2017, 2019; Brady, Gantman, & Van Bavel, 2020; Brady & Van Bavel, 2021; Crockett, 2017), and algorithms amplify this tendency (Brady et al., in press; Chakradhar, 2021; Chowdhury, 2021; Huszár et al., 2022). The widespread sharing of moral outrage has two consequences: It teaches users that outrage expressions are normative, and it directly reinforces those outrage expressions. Thus, users learn over time to express more outrage (Brady et al., 2021), which further inflates beliefs that outrage is normative. Inflated prior beliefs about the prevalence of outrage may then lower the threshold for perceiving it, causing individuals to believe others are more outraged than they actually are (Brady et al., 2023). We speculate that these algorithmic social-learning processes could extend beyond outrage expressions to affect other types of normative thinking. For example, simplified moral narratives with a clear villain and victim may generate more engagement than more nuanced accounts. Because social media algorithms gamify engagement, individuals may learn over time to communicate and perhaps even to cognitively represent moral situations in ways that essentialize moral character, which in turn increases harsh punitive attitudes (Heiphetz, 2020). Moreover, there is evidence that social media algorithms disproportionately incentivize and spread right-wing over left-wing political commentary in the United States (Huszár et al., 2022). Such incentives, over time, could promote not just the content of right-wing political views but also right-wing styles of normative thinking, such as moral parochialism (Bai et al., 2021; Kahane et al., 2018; Waytz et al., 2019). Furthermore, because social media algorithms disproportionately incentivize criticism directed toward outgroups (Rathje et al., 2021), this could increase the impact of social identity on normative thinking, making people quicker to blame and assume the worst intentions of out-group members.

TL;DR

This commentary extends Heyes's "cognitive gadgets" account of norm psychology to argue that social media can drive rapid cultural evolution of how people think and feel about norms, not just the content of norms themselves. The authors speculate that three features of social media—hidden incentives, context collapse, and speed of transmission—reshape normative cognition, and they call for designing technologies that steer this evolution toward global cooperation.

Key findings

  • The authors propose that social media's hidden incentives teach users new normative dispositions: because platforms profit from keeping users online, algorithms promote shareable content, and users are especially likely to share moralized, emotional language such as moral outrage. Widespread sharing of outrage teaches users that outrage is normative and directly reinforces outrage expression, so users learn to express more outrage over time, which further inflates beliefs that outrage is normative and can lower the threshold for perceiving it.
  • They speculate these processes extend beyond outrage to other normative thinking—e.g., simplified villain/victim moral narratives may out-engage nuanced accounts, potentially essentializing moral character and increasing harsh punitive attitudes; evidence cited indicates algorithms disproportionately incentivize and spread right-wing over left-wing political commentary in the United States, and disproportionately incentivize criticism of outgroups, which could heighten moral parochialism and out-group blame.
  • "Context collapse" (Marwick & Boyd, 2011) flattens multiple audiences into one, complicating reputation management because commentary meant for one audience may reach a very different one; some users develop strategies such as self-censorship, and as these strategies spread they may drive cultural evolution of more sophisticated reputation-management strategies optimized for digital spaces.
  • Unprecedented transmission speed increases social learning: users can observe thousands of reactions and receive feedback from thousands of people within minutes. Viral outrage "pile-ons" increase beliefs that outrage is normative but also increase sympathy for the offender when outrage seems disproportionate; observing rapid norm change may foster cynical beliefs about moral expression or a "normative nihilism" that drives retreat to perceived-traditional norms.

Methods

  • This is a conceptual commentary, not an empirical study; the authors explicitly "speculate" about how social media shapes the cultural evolution of normativity, building on Heyes's cognitive-gadgets account and on prior studies of online normative discourse.
  • The argument is organized around three features of social media: hidden incentives, multiple audiences (context collapse), and speed of transmission.
  • The text cites more than 4 billion social media users worldwide (Dixon, 2022) as context; no new data, sample, or statistical analysis is reported.

Limitations

  • The paper states no formal limitations section; the authors repeatedly frame their claims as speculation ("we speculate," "could," "may"), and the proposed consequences for normative cognition are not tested here.
  • Evident from the text: the argument is a theoretical synthesis relying on cited findings from other studies (e.g., outrage sharing, algorithmic amplification, context collapse), so the causal claims about social media reshaping norm psychology remain hypotheses rather than demonstrated effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
