An IZA discussion paper by Mohsen Javdani and Ha-Joon Chang examines the extent to which the dominant, ideologically narrow discourse in mainstream economics—embedded in its educational practices under the guise of objectivity and value-neutrality—biases the views of economics students.
Drawing on a large-scale online randomized controlled experiment with 2,735 economics students from 10 countries, the authors explore how hidden ideologies and power structures in economics shape students’ evaluations of statements on a range of economic issues. By interrogating the ideological dimensions of economics education, they aim to shed light on its broader social and intellectual implications—a subject of growing concern.
The Authority Bias Effect
When the source attributed to a statement is randomly switched from mainstream to non-mainstream, or removed entirely, students’ reported agreement drops significantly. Despite 67% of students claiming to assess arguments solely on their substance, this pattern suggests they rely heavily on the perceived authority and ideological alignment of mainstream sources.
These biases intensify with academic progression. PhD students show more than twice the bias against non-mainstream sources compared to undergraduates and master’s students. This reflects how prolonged exposure to mainstream ideas—and a self-selection process that rewards those who “think like an economist”—entrenches the very biases economics claims to avoid through its emphasis on neutrality.
The Paradox of Advanced Education
Ironically, PhD students also present themselves as the most committed to critical thinking and independence: 76% endorse judging arguments solely on substance, compared to 62% of master’s students and 55% of undergraduates. Yet their evaluative behavior suggests otherwise—those who claim to be most resistant to bias appear the most influenced by it.
Political ideology further amplifies these biases, particularly among right-leaning students. Political orientation significantly shapes agreement levels, even when statements are attributed to mainstream sources. Across all academic levels, a shift from far left to far right consistently reduces agreement with mainstream-attributed statements. Right-leaning students are more likely to reject views that challenge or diverge from orthodoxy—even when such views originate within the mainstream. Political orientation also interacts significantly with students’ ideological and authority biases, provoked by changes in attributed sources.
Political and Gender Dimensions
These effects are present across all academic levels but are most pronounced among PhD students. On the far left, switching to a non-mainstream source reduces agreement among PhDs by 18.6% of a standard deviation—compared to 1.2% among undergraduates and 9.6% among master’s students. Among PhD students at the political center, the reduction is 38%; on the far right, it rises to 64%—a 230% increase from the far-left effect. These results point to the increasingly dominant role political orientation plays in shaping how advanced students engage with non-mainstream ideas.
Gender is another critical dimension of these biases. Male students exhibit substantially stronger reactions to source changes. Switching from a mainstream to a non-mainstream source reduces agreement among male students by 20% of a standard deviation, compared to 7.5% for female students—a 62% smaller effect. When source attribution is removed entirely, the reduction is 37% for men and 27% for women—a 25% smaller effect. These gender differences persist even after accounting for potential systematic variation in political ideology, pointing to deeper, gendered dynamics in how economic knowledge is received and processed.
Implications for Economics Education
The study contributes to the growing debate about the narrow ideological framework of economics education and calls for greater pluralism. By identifying a concrete manifestation of ideological and authority bias, the findings highlight how economics’ rigid discourse shapes pedagogy, socializes students into a particular mindset, and reproduces institutional power dynamics that define disciplinary norms. These forces limit students’ ability to think independently and critically engage with the content of their education.
The implications extend beyond the classroom. Given the generative nature of ideology, these biases are likely to influence students’ future research, policy preferences, and broader civic and professional outlooks. According to the authors, economics education is in urgent need of reform.
The Path Forward: Embracing Pluralism
Their findings suggest that a more pluralistic approach—one that integrates diverse theoretical traditions, methodological frameworks, and real-world contexts—would provide students with a deeper, more critical understanding of economic life. Such an approach would expose students to non-mainstream traditions (such as institutional, feminist, post-Keynesian, Marxian, and ecological economics) and foster engagement with the historical, political, and ethical dimensions of economic decision-making.
Recognizing the value-laden and ideological aspects of economics discourse is crucial for cultivating a more inclusive and pluralistic discipline—one capable of addressing real-world complexities. This awareness also benefits students, encouraging them to approach their studies with epistemic humility and critical thinking, rather than passively accepting the dominant paradigm as universal truth. True pluralism demands openness to fundamentally different perspectives, not just minor adjustments to the neoclassical framework and its ideological foundations.
