S8 Ep13: The class gap in career progression

Episode Summary

Executive Summary: This episode examines Anna Stansbury and Kyra Rodriguez’s research on class background and career progression in U.S. academia. Using a large STEM PhD dataset, they find that first-generation college graduates are less likely to reach high-profile tenure-track roles and that the gap persists into tenure decisions. The findings suggest class matters beyond access to elite education, likely through networks and mentorship rather than productivity or ambition.

Main Topics: Why class matters in academia (Priority: 5/5): The discussion challenges the common assumption that socioeconomic background only shapes early educational outcomes, arguing it may also affect advancement after entry into elite professions. Why academia is the chosen setting (Priority: 4/5): Academia is used because it is an elite profession with unusually rich data on productivity and background, making it possible to study class effects directly. Measuring class background and career progression (Priority: 5/5): Class is defined through parental education, income/wealth, and occupation, and the study tracks outcomes along the tenure-track pipeline in U.S. academia. Evidence of a persistent class gap (Priority: 5/5): Comparing people from the same PhD program, first-generation college graduates are less likely to land high-profile research-intensive tenure-track or tenured jobs, and the gap remains at promotion. Mechanisms: productivity, networks, and ambition (Priority: 5/5): The researchers find little evidence that lower-class academics are less productive or less ambitious; instead, network formation and mentoring appear to be the likely channel. Meritocracy and reform (Priority: 4/5): The conversation argues that academia’s meritocratic self-image is incomplete and that better mentorship, transparency, and awareness of class-coded signals could reduce inequities.

Key Arguments: Class background affects not only access to elite education but also career advancement after entry into academia. The study isolates the effect by comparing individuals from the same PhD program, reducing concerns that the gap is only due to different graduate-school pipelines. First-generation college graduates are about 13% less likely to reach high-profile research-intensive tenure-track or tenured jobs than peers from more advantaged backgrounds. The class gap persists, and may widen slightly, through the tenure and promotion stage. The gap is not explained mainly by differences in research productivity; similar-output candidates still experience different outcomes. There is no strong evidence that lower-class researchers are less ambitious in terms of seeking intellectually challenging or prestigious work. Co-authorship patterns suggest first-generation college graduates have smaller or more constrained professional networks, likely affecting recommendations, mentorship, and job placement. The size of the class gap is similar to known race and gender gaps at this career stage, so it deserves comparable attention. Academia’s meritocratic ideal is undermined by hidden biases and class-coded judgments about polish, professionalism, and brilliance. Potential remedies include stronger mentorship, less sink-or-swim PhD environments, more transparent opportunity distribution, and awareness of class-based judgments.

Data Points: Sample size: About 80,000 people - STEM PhD recipients across science, technology, engineering, math, and social sciences in the U.S. Economists in dataset: A few thousand - Subset of the larger STEM/social science sample Class-gap outcome: 13% less likely - First-generation college graduates are less likely to end up in a high-profile research-intensive tenure-track or tenured job than peers from the same PhD program Career stage: 6 to 8 years - Typical time on tenure track before a tenure decision in the U.S. Comparison basis: Same PhD program - Used to isolate class effects beyond graduate-school selectivity Race control: Controlled for in all analyses - To compare people of the same race with different parental education backgrounds

Pivotal Quotes: "they're not, really" — Anna Stansbury: Answering whether economists and social scientists pay enough attention to class background "the big takeaway is these magnitudes of these gaps are about the same size" — Anna Stansbury: Comparing class gaps with established race and gender gaps in academia "a really destructive illusion to believe that we are not subject to those biases" — Anna Stansbury: Discussing academia’s meritocratic self-image

Implications: Class background continues to shape elite career outcomes even after entry into academia. Institutions should treat class gaps like other diversity barriers and improve mentoring, transparency, and awareness of class-coded evaluations.
