Abstract
Stereotypes are a foundational construct in psychological science, often defined as beliefs concerning characteristic group attributes. We present a cognitive-ecological theory of social perception that predicts and explains why such characteristic attributes are likely negative, that is, why most stereotypes are negative. The theory assumes that, cognitively, people characterize groups by attributes that distinguish them from other groups. Ecologically, positive social information is more frequent (i.e., positivity prevalence), and negative social information is more diverse (i.e., negativity diversity). If negative attributes are less frequent and more diverse relative to positive attributes, then they must be more likely to distinguish one group from another. Consequently, the attributes people see as characteristic of a group are likely to be negative. We illustrate the predicted stereotype negativity across two studies and two existing data sets. We then formalize the theory and illustrate it with simulations showing that rare attributes can be highly diagnostic of group membership while applying to only a minority of group members. Thus, the theory explains why most stereotype content is likely negative, despite the well-documented positivity prevalence, and why stereotypes may be diagnostic and comparatively accurate, despite being descriptively inaccurate. The theory explains stereotype negativity without requiring motivational derogation, essentialist group differences, or a general negativity bias, and it clarifies when positive stereotypes should occur. We also discuss the theory’s relation to dimensional models of stereotype content and consequences for interventions aimed at reducing stereotype negativity.
We propose that most stereotypes about most social groups are negative. To be precise, we propose that stereotype content is predominantly negative. This proposition of stereotype negativity seems intuitively true, but it is also paradoxical given that social interactions between people are usually positive.1 People are more often nice than rude, they more often hug than slap each other, and they smile more often than frown (e.g., Alves et al., 2017a). People also expect others to act positively (e.g., Katzir & Posten, 2023; Sears, 1983) and more likely describe them with positive attributes (e.g., Boucher & Osgood, 1969; Leising et al., 2014). We argue that most stereotypes are negative, not despite this general positivity, but because of it. Stated differently, we will show that in a predominantly positive social world, stereotypes are likely predominantly negative.
We will delineate a cognitive-ecological theory that explains this apparent contradiction, based on (a) the functional nature of stereotypes (e.g., Macrae, Milne, & Bodenhausen, 1994), (b) the structure of people’s evaluative information ecology (Alves et al., 2017b; Unkelbach et al., 2019, 2020), and (c) the cognitive principle of differentiation and attentional learning (Alves et al., 2022; Kruschke, 2003; Sherman et al., 2009). In addition, as a corollary, we will also argue that stereotypes are predominantly inaccurate (see also Bai et al., 2022). In short, we will show that negative attributes make “good” stereotypes in a diagnostic sense; however, not because of their valence but because they differentiate between groups.
The proposition of stereotype negativity is also present in the assumption that stereotypes provide a cognitive basis for bias and discrimination (see Fiske & Tablante, 2015, for an overview chapter) and may serve to justify existing inequalities (see Jost, 2019, for a review). It also aligns with the negative consequences of stereotypes. For example, they impair performance (e.g., Steele & Aronson, 1995), they derail social exchanges (e.g., Dorrough & Glöckner, 2016), and people feel bad when they stereotype someone (e.g., Monteith, 1993). All these consequences fit with the hypothesis that most stereotypes are negative. Although negative consequences might also follow from positive stereotypes (e.g., Siy & Cheryan, 2013; see Czopp et al., 2015, for a review), and positive stereotypes may also lead to bias and discrimination, negative consequences follow more directly when stereotypes are negative.
We will also delineate the similarities and differences between this cognitive-ecological theory and social identity–based explanations (Tajfel & Turner, 1986), related societal explanations (Jost, 2019; Pratto et al., 2006), and explanations based on a general negativity bias (Baumeister et al., 2001; Rozin & Royzman, 2001). We believe these explanations complement each other, but we aimed to show that stereotype negativity follows even without any affective, motivational, or evolutionary necessities.
Are stereotypes mostly negative? Or, instead, are college graduates instructed to stereotype stereotypes as negative?
For example, I often write about desirable and undesirable neighborhoods in Southern California, whether directly or just to cite examples in passing. What I notice is that I have a large repertoire of desirable SoCal neighborhoods to cite — e.g. Beverly Hills, West Hollywood, Bel-Air, Brentwood, Westwood, Santa Monica, Manhattan Beach, Palos Verde, Newport Beach, San Marino, and Arcadia (which I’ve probably done more to stereotype for its abundance of National Merit Scholars than anybody else). That’s because good things tend to be more famous than bad things.
In contrast, I have a pretty small repertoire of undesirable SoCal neighborhoods that I mention in the expectation that you’ve heard of it and know of its bad reputation: mostly, I use Compton as my go-to example. And Compton isn’t as bad anymore as it was when NWA self-mythologized it in the first big gangsta rap album in 1988, Straight Outta Compton. Indeed, Compton was never all that awful — the housing stock was built to be decent. That’s why two future Presidents lived in Compton in 1949-50.
I don’t go out of my way to use the names of other downscale, crime-ridden SoCal neighborhoods besides Compton because they are obscure and it would be easy to miss the point I’m making if I used Huntington Park or some other boring nowheresville as a reference.
Am I stereotyping Compton?
Yeah, sure.
Am I stereotyping Beverly Hills?
Paywall here.
