Alice Eagly

Introduction

Alice H. Eagly, born Alice Hendrickson in Los Angeles in 1938, is an American social psychologist and emerita professor of psychology at Northwestern University, where she holds the James Padilla Chair of Arts and Sciences Emerita and is a Faculty Fellow Emerita at the Institute for Policy Research. She was elected to the National Academy of Sciences in 2022, one of the highest honours available to an American scientist.

Her central theoretical achievement is social role theory, the argument that many psychological differences between women and men are not expressions of innate disposition but consequences of the division of labour. Because women and men have historically occupied different roles — homemaker and breadwinner most obviously — they have been expected to display, and have come to display, different behaviours, and observers have converted those observations into stereotypes.

Eagly has spent her career testing that claim with an unusual toolset for a social psychologist: large-scale meta-analysis. Her work on women and leadership, on the content of stereotypes, and on the magnitude of sex differences has made her one of the most cited figures in the psychology of gender, and has placed her at the centre of the discipline's longest-running argument about nature, nurture, and politics.

Early Life and Education

Eagly was born in Los Angeles in 1938 to Harold and Josara Hendrickson and grew up in California and Washington State. She entered Harvard University, then unusual for an undergraduate woman, and completed a degree in Social Relations in 1960 — an interdisciplinary programme combining sociology, anthropology, and psychology that shaped her habit of explaining psychological phenomena through social structure.

She then went to the University of Michigan for graduate study, where she earned a master's degree in psychology and a doctorate in social psychology. Her early work was on attitudes and persuasion, and specifically on a puzzle in the literature of the 1970s: the repeated finding that women were more persuadable than men. Eagly's review concluded that the effect was not a property of women at all but of social status — people in lower-status positions appear more influenceable. That reconstrual, attributing an apparent sex difference to a structural variable, established the pattern for everything that followed.

In 1962 she married Robert Eagly, whom she had met while studying in Norway. The couple had not planned to reverse conventional roles, but as her career advanced they concluded that Robert should become the stay-at-home parent. Eagly has noted the irony that her own household became an instance of the phenomenon she studied — though she has also been careful to point out that an individual biography proves nothing about the general case, and that the theory stands or falls on aggregate data rather than on examples.

Academic and Professional Career

Eagly held faculty positions at Michigan State University, the University of Massachusetts, and Purdue University before joining Northwestern, where she spent the rest of her career. She also held visiting positions at the University of Illinois, Harvard University, the University of Tübingen, the University of Amsterdam, and the University of Southern California.

She served as president of both the Society for Personality and Social Psychology and the Society for the Psychological Study of Social Issues, and has authored or co-authored seven books and more than a hundred journal articles. Alongside her gender research she maintained a second, parallel research programme on attitudes; her 1993 volume with Shelly Chaiken, The Psychology of Attitudes, became the standard reference in that field.

Her honours include the American Psychological Association's Distinguished Scientific Contribution Award, the American Psychological Foundation's Gold Medal for Life Achievement in the Science of Psychology, the Interamerican Psychologist Award, the Carolyn Wood Sherif Award from the Society for the Psychology of Women, the Raymond A. Katzell Award from the Society for Industrial and Organizational Psychology, and the 2011 Berlin Prize from the American Academy in Berlin. She is a member of the American Academy of Arts and Sciences and holds honorary doctorates from the University of Bern, Erasmus University Rotterdam, and the University of Lausanne.

Major Contributions to Psychology

Social role theory, first set out in her 1987 book Sex Differences in Social Behavior, holds that the division of labour produces both behavioural differences and the stereotypes that rationalise them. People observe women doing caretaking work and men doing physical or supervisory work, infer that women are communal and men agentic, and then treat those inferred traits as if they were the cause rather than the consequence of the original arrangement.

A counterintuitive implication, which Eagly and her collaborators documented, is that women are in some respects stereotyped more favourably than men — as warmer and more nurturing. This does not make the stereotype benign, because warmth suits women for lower-status roles, and it complicates any account of prejudice as simple antipathy.

Role Congruity Theory and Women in Leadership

With Steven Karau, Eagly developed role congruity theory, published in Psychological Review in 2002. Prejudice, on this account, arises when a group's stereotype mismatches the requirements of a role: because leadership is stereotyped as agentic and masculine, women who lead are judged as deficient in the role, and women who lead in a stereotypically masculine style are penalised for violating prescriptions about how women should behave. The resulting double bind was substantiated by meta-analysis and became the dominant framework for research on women in leadership. Her 2007 book with Linda Carli, Through the Labyrinth, presented the argument for a general audience.

Stereotype Content

Eagly extended the role-based account to stereotypes generally. With Anne Koenig, she argued that stereotype content is not arbitrary but derived from observation of the roles that group members typically occupy — an argument tested in a 2014 article in the Journal of Personality and Social Psychology and developed further in a 2019 article in Social Psychology Quarterly. The work offers a social-structural alternative to accounts that treat stereotyping as a free-floating cognitive error.

Feminism, Science, and Advocacy

Eagly has also written about the institutional politics of her own field. With colleagues including Stephanie Riger, she examined how feminist methodological and epistemological critiques relate to contemporary psychological science, and in a 2018 article in the Journal of Social Issues she argued against accounts that attribute women's disadvantage to a single external cause, urging attention to multiple interacting influences instead. Throughout, she has maintained a distinction that runs through her career: that a psychologist can hold feminist commitments and still insist that conclusions follow the evidence rather than the commitment.

The Magnitude of Sex Differences

In a 2022 article with William Revelle in Perspectives on Psychological Science, Eagly addressed a long-standing inconsistency: some researchers report that women and men are very similar on most psychological variables, others that differences are large. Her answer was psychometric. Aggregate scales — combining many indicators into a broad measure of how typical a construct is of women or men — produce much larger differences than their component items, and multivariate distances across domains such as vocational interests are larger still. Both the similarity claim and the difference claim can be correct, depending on how the data are organised.

Impact and Legacy

Eagly's framework reshaped how psychology explains gender. Before social role theory, sex differences in social behaviour were most often explained by socialisation or, increasingly after 1990, by evolved psychological mechanisms. Eagly offered a third account rooted in the observable structure of society, and — crucially — one that generates testable predictions about when differences should shrink.

Those predictions are where the criticism has concentrated. The most substantial empirical challenge is what has come to be called the gender-equality paradox: in the most gender-egalitarian countries, particularly the Nordic states, several psychological and educational sex differences are as large as or larger than in less egalitarian societies, which is the opposite of what a straightforward reading of social role theory predicts. Costa, Terracciano, and McCrae's 2001 cross-national study of personality across dozens of cultures found larger differences in more Western and more egalitarian nations, a result critics have used to argue that the theory's core mechanism is at best incomplete.

Evolutionary psychologists have pressed a related objection: that social role theory struggles to explain the cross-cultural universality of certain differences, and that its appeal is partly political, since it attributes inequality to social arrangements that can be changed. Eagly's response has been twofold. First, she and Wendy Wood developed a biosocial version of the theory which explicitly grants that the division of labour originates in evolved physical differences — men's greater size and strength, women's capacity for gestation and nursing — interacting with a society's ecology and technology. Second, she has argued that the field should resist both the "just-so" stories of evolutionary explanation and the pressure of political correctness, and be open to whatever the data show; she made exactly this case in a 1995 American Psychologist article on the science and politics of comparing women and men.

Her 2022 paper with Revelle has itself been contested. By showing that aggregated measures inflate differences, it complicates Janet Hyde's widely cited gender-similarities hypothesis, and critics have argued that emphasising multivariate distance risks overstating how distinct women and men actually are in everyday terms. Eagly and Revelle's point is narrower than the reaction suggests — that similarity and difference are two descriptions of the same data rather than rival findings — but the exchange has made the measurement question central to the field.
