Why are some fields and occupations more diverse than others? In this review, we describe a conceptual framework—the Field-specific Ability Beliefs (FAB) model—that provides a promising answer to this question. This model proposes that gender and racial/ethnic imbalances in a field or occupation result in part from the confluence of two beliefs: (a...
Essentialist beliefs (i.e., believing that members of the same group are fundamentally alike) play a central role in social stereotypes and can lead to harm when left unchallenged. In our work, we conduct exploratory studies into the task of countering essentialist beliefs (e.g., ``liberals are stupid''). Drawing on prior work from psychology and N...
Generic language (e.g., “tigers have stripes”) leads children to assume that the referenced category (e.g., tigers) is inductively informative and provides a causal explanation for the behavior of individual members. In two preregistered studies with 4‐ to 7‐year‐old children (N = 497), we considered the mechanisms underlying these effects by testi...
Language that uses noun labels and generic descriptions to discuss people who do science (e.g., "Let's be scientists! Scientists discover new things") signals to children that "scientists" is a distinctive category. This identity-focused language promotes essentialist beliefs and leads to disengagement from science among young children in experimen...
Language that uses noun labels and generic descriptions to discuss people who do science (e.g., “Let’s be scientists! Scientists discover new things”) signals to children that scientists are a distinctive category. This identity-cuing language promotes essentialist beliefs and leads to disengagement from science among young children in experimental...
Feeling like an impostor is common among successful individuals, but particularly among women and early-career professionals. Here, we investigated how gender and career-stage differences in impostor feelings vary as a function of the contexts that academics have to navigate. In particular, we focused on a powerful but underexplored contextual feat...
A problematic way to think about social categories is to essentialize them—to treat particular differences between people as marking fundamentally distinct social kinds. From where do these beliefs arise? Language that expresses generic claims about categories elicits some aspects of essentialism, but the scope of these effects remains unclear. Thi...
Subtle features of common language can imply to young children that scientists are a special and distinct kind of person—a way of thinking that can interfere with the development of children’s own engagement with science. We conducted a large field experiment (involving 45 prekindergarten schools, 130 teachers, and over 1,100 children) to test if t...

Subtle features of common language can imply to young children that scientists are a special and distinct kind of person—interfering with the development of children’s own engagement with science. We conducted a large randomized-control trial (involving 45 pre-kindergarten schools, 130 teachers, and over 1,100 children from diverse backgrounds) to...
This chapter distinguishes the clusters of psychologically real heuristics that govern our use of terms—the “psi-concepts”—from the “phi-concepts” or meanings that are the semantic determinants of the extensions of the terms in question, and hence of the truth-conditions of the sentences that contain those terms. Concerning the psi-concepts the cha...
Over the course of middle childhood, children's interest and beliefs about their own capacities for success in science often decline. This pernicious decline is especially evident among underrepresented groups, including girls, members of some racial and ethnic minorities, and children from lower socioeconomic backgrounds. The present research (N=3...
A striking characteristic of human thought is that we form representations about abstract kinds (Giraffes have purple tongues), despite experiencing only particular individuals (This giraffe has a purple tongue). These generic generalizations have been hypothesized to be a cognitive default, that is, more basic and automatic than other forms of gen...
The roots of gender disparities in science achievement take hold in early childhood. The present studies aimed to identify a modifiable feature of young children's environments that could be targeted to reduce gender differences in science behavior among young children. Four experimental studies with children ( N = 501) revealed that describing sci...
Generic language (e.g., “tigers have stripes”) facilitates conceptual development, by leading listeners to assume that the referenced categories (e.g., tigers) are inductively informative and have causal-explanatory power over the behavior of individual members. The present studies (N = 441 children aged 5-7 years and adults) considered the mechani...
Despite the numerous intellectual contributions made by women, we find evidence of bias against them in contexts that emphasize intellectual ability. In the first experiment, 347 participants were asked to refer individuals for a job. Approximately half of the participants were led to believe that the job required high-level intellectual ability; t...
A common misconception about math is that it requires raw intellectual talent or "brilliance." Only students who possess this sort of brilliance are assumed to be capable of success in math-related subjects. This harmful myth has far-reaching consequences for the success of girls and children from ethnic-minority backgrounds in these subjects. Beca...
Pervasive cultural stereotypes associate brilliance with men, not women. Given these stereotypes, messages suggesting that a career requires brilliance may undermine women’s interest. Consistent with this hypothesis, linking success to brilliance lowered women’s (but not men’s) interest in a range of educational and professional opportunities intro...
This paper analyzes the scripts of children's television shows and reveals that references to scientists in children's media are often generic in nature.
How a misplaced emphasis on genius subtly discourages women and African-Americans from certain academic fields
Generic generalizations such as 'mosquitoes carry the West Nile virus' or 'sharks attack bathers' are often accepted by speakers despite the fact that very few members of the kinds in question have the predicated property. Previous work suggests that such low-prevalence generalizations may be accepted when the properties in question are dangerous,...
The present study investigates the processes by which essentialist beliefs about religious categories develop. Children (ages 5 and 10) and adults (n = 350) from 2 religious groups (Jewish and Christian), with a range of levels of religiosity, completed switched-at-birth tasks in which they were told that a baby had been born to parents of 1 religi...
Emergent attitudes toward brilliance
The distribution of women and men across academic disciplines seems to be affected by perceptions of intellectual brilliance. Bian et al. studied young children to assess when those differential perceptions emerge. At age 5, children seemed not to differentiate between boys and girls in expectations of “really,...
Classifying people into categories not only helps humans simplify a complex social world but also contributes to stereotyping and discrimination. This research examines how social categorization develops by testing how language imbues with meaning otherwise arbitrary differences between people. Experimental studies (N = 129) with 2-year-olds showed...
Psychological essentialism is a pervasive conceptual bias to view categories as reflecting something deep, stable, and informative about their members. Scholars from diverse disciplines have long theorized that psychological essentialism has negative ramifications for inter-group relations, yet little previous empirical work has experimentally test...
Theorists have had less success in analyzing the truth conditions of generics. Philosophers of language have offered a number of theories. This chapter surveys several semantic accounts of generics. However, the focus is on generics and experimental philosophy. It briefly reviews empirical work that bears on these semantic accounts. While generics...
Supporting Information for The Frequency of “Brilliant” and “Genius” in Teaching Evaluations Predicts the Representation of Women and African Americans across Fields
(PDF)
Women and African Americans—groups targeted by negative stereotypes about their intellectual abilities—may be underrepresented in careers that prize brilliance and genius. A recent nationwide survey of academics provided initial support for this possibility. Fields whose practitioners believed that natural talent is crucial for success had fewer fe...
Generic language (

All owls

This paper explores the role of generics in social cognition. First, we explore the nature and effects of the most common form of generics about social kinds (descriptive generics). Second, we discuss the nature and effects of a less common but equally important form of generics about social kinds (normative generics). Finally, we consider the impl...
Ginther and Kahn claim that academics’ beliefs about the importance of brilliance do not predict gender gaps in Ph.D. attainment beyond mathematics and verbal test scores. However, Ginther and Kahn’s analyses are problematic, exhibiting more than 100 times the recommended collinearity thresholds. Multiple analyses that avoid this problem suggest th...
An acquaintance of mine once remarked, “Hillary Clinton is the only man in the Obama administration”. This acquaintance was not confused about basic descriptive facts concerning the Obama administration, but rather was offering a colorful, negative evaluation of the members of the administration. With this comment, the speaker managed to derogate b...
Recently, several scholars have hypothesised that generics are a default mode of generalisation, and thus that young children may at first treat quantifiers as if they were generic in meaning. To address this issue, the present experiment provides the first in-depth, controlled examination of the interpretation of generics compared to both general...
Women’s underrepresentation in science, technology, engineering, and mathematics (STEM) fields is a prominent concern in our society and many others. Closer inspection of this phenomenon reveals a more nuanced picture, however, with women achieving parity with men at the PhD level in certain STEM fields, while also being underrepresented in some no...
Women's participation and attitudes to talent
Some scientific disciplines have lower percentages of women in academia than others. Leslie et al. hypothesized that general attitudes about the discipline would reflect the representation of women in those fields (see the Perspective by Penner). Surveys revealed that some fields are believed to require...
Much evidence suggests that, from a young age, humans are able to generalize information learned about a subset of a category to the category itself. Here, we propose that—beyond simply being able to perform such generalizations—people are biased to generalize to categories, such that they routinely make spontaneous, implicit category generalizatio...
Psychological essentialism is the belief that some internal, unseen essence or force determines the common outward appearances and behaviors of category members. We investigated whether reasoning about transplants of bodily elements showed evidence of essentialist thinking. Both Americans and Indians endorsed the possibility of transplants conferri...
Generic sentences express generalizations about kinds, such as “tigers are striped,” “ducks lay eggs,” and “ticks carry Lyme disease.” I present and review emerging evidence from adults and children that suggests that generics articulate cognitively default generalizations—i.e., they express basic, early-developing generalizations concerning kinds....
Social essentialism entails the belief that certain social categories (e.g., gender, race) mark fundamentally distinct kinds of people. Essentialist beliefs have pernicious consequences, supporting social stereotyping and contributing to prejudice. How does social essentialism develop? In the studies reported here, we tested the hypothesis that gen...
People routinely make inferences based on kind membership. For example, if you were told that a particular kind of animal is a tiger, then you would likely infer that it has stripes. Under what conditions are people willing to infer that a member of a given kind has a property? Two hypotheses were examined. The base rate or prevalence hypothesis ho...
Generics are sentences such as "ravens are black" and "tigers are striped", which express generalizations concerning kinds. Quantified statements such as "all tigers are striped" or "most ravens are black" also express generalizations, but unlike generics, they specify how many members of the kind have the property in question. Recently, some theor...
Generic statements (e.g., "Lions have manes") make claims about kinds (e.g., lions as a category) and, for adults, are distinct from quantificational statements (e.g., "Most lions have manes"), which make claims about how many individuals have a given property. This article examined whether young children also understand that generics do not depend...
Prasada and Dillingham (2006, 2009) and Leslie (2007, 2008) hypothesize that 'bare plural' generics (e.g. "tigers are striped") are used to express a range of conceptually different types of generalizations. We investigate whether different syntactic forms of generics are restricted to expressing only some of these types of generalizations, and if...
We examine the extent to which people's judgments about whether a given member of a kind has a property are guided by prevalence estimates alone, or whether their acceptance of a generic generalization also impacts these judgments. Our data are not accounted for by prevalence estimates alone: acceptance of a generic disposes people to infer that, b...
Higginbotham (1986) argues that conditionals embedded under quantifiers (as in ‘no student will succeed if they goof off')
constitute a counterexample to the thesis that natural language is semantically compositional. More recently, Higginbotham
(2003) and von Fintel and Iatridou (2002) have suggested that compositionality can be upheld, but only i...
`Ducks lay eggs' is a true sentence, and `ducks are female' is a false one. Similarly, `mosquitoes carry the West Nile virus' is obviously true, whereas `mosquitoes don't carry the West Nile virus' is patently false. This is so despite the egg-laying ducks' being a subset of the female ones and despite the number of mosquitoes that don't carry the...
Generics are statements that are not explicitly quantified and that express generalizations, such as 'ducks lay eggs'. Intuitively, the generic (non-quantified) form of such statements seems to be true. Furthermore, people seem to be prone to an interesting error: treating the universal form of characteristic generic assertions (e.g., 'all ducks la...
Generics are statements that express generalizations, such as 'ducks lay eggs'. Intuitively, such statements seem true. Even the universal form of such statements e.g., 'all ducks lay eggs' seems true, despite our knowing that the majority of ducks do not. We conducted an experiment to verify these intuitions, and found that people overwhelmingly j...
Introduction It is common practice in philosophy to 'rely on intuitions' in the course of an argument, or sometimes simply to establish a conclusion. One question that is therefore important to settle is: what is the source of these intuitions? Correspondingly: what is their epistemological status? Philosophical discussion often proceeds as though...

... The first moderator we investigated was parents' and mentors' field-specific ability beliefs (or FABs) about chess. Fields and occupations differ in the extent to which intellectual talent ("brilliance") is seen as necessary for success (for a review, see Muradoglu et al., 2023). Contexts with more brilliance-oriented FABs are less welcoming to women, in part because of greater prejudice against them (Bian et al., 2018;Hannak et al., 2023;Leslie, Cimpian, et al., 2015). ...
... On this account, the pathway from generics to social essentialism is independent of the content of the generic statements and the consequent inherent explanations. According to this account, children learn to essentialize categories very early on and generic language signals to them which social categories are salient in their communities and prime "candidates" for essential reasoning (Benitez et al., 2022, Foster-Hanson et al., 2022. Consequently, regardless of the explicit information communicated in a generic sentence, using generic terms (e.g., "Turks") signals to children that these categories are culturally relevant and appropriate targets for essentialization. ...
... These include gender differences in available role models, parental encouragement, and gender-biased comments from peers and adults. First, boys are more likely than girls to see their gender ingroup represented as physicists, astronomers, computer scientists, or engineers in classrooms and popular media (e.g., Wang et al., 2022). Second, research suggests that many parents may encourage activities related to math, science, and technology more likely for their sons than daughters from childhood into adolescence (e.g., Eccles, 2015). ...

... More recently, literature on Black women academics' experiences at university has looked at the invisible labour that Black women academics often take on, and that is often unrecognised, unseen, and under-valued in the academy. The literature has explored the resilience shown by Black women academics in senior leadership; the racism, sexism, and disconnection experienced by Black women in STEM fields; Black women's efforts at challenging and confronting anti-Blackness and White supremacy in academia; and more (see Blell et al., 2022;Muradoglu et al., 2022;Vohlídalová, 2021). In this paper, we contribute to this emerging body of research that looks at, and theorises, Black women academics' experiences in navigating their being and belonging in a South African university. ...
... Because generics allow for exceptions-indeed, they can express properties that are more typically false than true (e.g., "Birds lay eggs" is considered true, even though male birds and baby birds do not lay eggs)-they minimize variability within a category (41)(42)(43). Experiments have found that hearing or reading generics about novel categories results in: high levels of within-category inferences (44,45); treating the features expressed as especially central (46); and essentializing the category in question (47)(48)(49). Moreover, if two categories (A and B) contrast with one another, then a generic true of category A is assumed to be not true of category B (50)(51)(52). ...
... Students prefer workshops to projects and lectures. Hands-on approaches at an early age when students are "doing the science" may be more affective compared to the "being a scientist" approach [8], with parents playing an important role in the process [9]. The wow effect is well known in marketing and is created by the perception of a memorable experience related to a product or service. ...
... We might expect to see the same inferential asymmetry for social categories as was observed for animal kinds, given that people often reason about social categories as if they were natural kinds (Prentice & Miller, 2007;Rhodes & Gelman, 2009;Rothbart & Taylor, 1992). Consistent with this possibility, generic language promotes essentialist reasoning in both domains (Foster-Hanson, Leslie, & Rhodes, 2016Gelman, Ware, & Kleinberg, 2010;Leshin et al., 2020;Rhodes, Leslie, & Tworek, 2012, 2018a, 2018b. ...
... The lack of diversity, equity, and inclusion in science poses a hindrance to the advancement of citizen science. This challenge is especially pronounced for gender, racial, and ethnic minorities, as well as women and individuals from lower socio-economic backgrounds [138]. We hope that by making SDLs low-cost, ac-cessible, and open source, it will be easier to build equity and inclusion into the educational system. ...
... If people tend to recall statements about political positions as generic, it would suggest that the polarizing language of generics (established in study 1) is how information about groups tends to be stored in memory. Given prior research demonstrating that categories exaggerate perceptions of between-group differences two (e.g., "Bears" vs. "All bears," when recalling "All bears climb trees"; see also ref. 65). If it did, then we would expect a generic advantage regardless of what is expressed, but the generic advantage holds only when the quantifier is broad in scope (e.g., all vs. some; 53), and only when the property expressed is generalizable (e.g., fur color vs. getting muddy; 66). ...
... In most European languages there is a distinction between the male and female form of scientist, for example. Past studies show that language can influence stereotype formation (Cimpian & Markman, 2011;Rhodes et al., 2019). Other research shows that naming science as behaviour or action rather than as a fixed identity contributes to the interest of young girls (4 to 9 years old) in technology. ...
