Came across this interesting paper on using AI to assess the Big 5 personality traits and predict career outcomes. This could have implications not just for the job market, but also in other fields like education which I covered earlier.
For more details, take your pick from the podcast:
or the AI summary:
A recent study explores how artificial intelligence (AI) can extract personality traits from facial images and how these traits correlate with labor market outcomes. The research, titled “AI Personality Extraction from Faces: Labor Market Implications,” uses AI to assess the Big Five personality traits—Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism—from facial images of 96,000 MBA graduates. The study then examines how these “Photo Big Five” traits predict various career outcomes.
Key Findings
- Predictive Power: The Photo Big Five traits can predict MBA school rank, compensation, job seniority, and career advancement. Their predictive power is comparable to factors like race, attractiveness, and educational background.
- Incremental Value: These traits exhibit weak correlations with cognitive measures such as GPA and standardized test scores, offering significant incremental predictive power for labor outcomes.
- Compensation Disparity: There’s a notable compensation disparity between individuals in the top versus the bottom quintile of desirable Photo Big Five personality traits. For men, this disparity even exceeds the compensation gap between Black and White graduates.
- Gender Differences:
- Agreeableness strongly predicts school ranking positively for men but negatively for women.
- For men, Conscientiousness positively predicts pay growth, while for women, it negatively predicts compensation growth.
- Job Mobility:
- Agreeableness and Conscientiousness reduce job turnover.
- Extraversion and Neuroticism increase job turnover.
- Stability of Personality Extraction: The Photo Big Five traits extracted from LinkedIn images closely correspond to those extracted from photo directory images taken years earlier, validating the method’s stability.
- Ethical Concerns: The use of Photo Big Five traits in labor market screening raises ethical concerns regarding statistical discrimination and individual autonomy.
Methodology
- AI Algorithm: The AI methodology employs an algorithm developed by Kachur et al. (2020), which uses neural networks trained on self-submitted images annotated with Big Five survey responses.
- Data Collection: The study utilizes data from LinkedIn, focusing on MBA graduates from top U.S. programs between 2000 and 2023.
- Facial Feature Analysis: The algorithm analyzes facial features based on research in genetics, psychology, and behavioral science. Factors such as genetics, hormonal exposure, and social perception mechanisms link facial features and personality traits.
Implications
This research highlights the increasing role of AI in assessing human capital and its potential impact on labor market dynamics. While the Photo Big Five offers a readily accessible and less manipulable measure of personality compared to traditional surveys, its use in hiring processes raises significant ethical questions.
Key considerations include:
- Statistical Discrimination: Relying on AI-extracted personality traits could perpetuate biases and lead to unfair treatment of candidates based on characteristics inferred from their appearance.
- Individual Autonomy: Using facial analysis to determine personality traits without consent infringes on personal privacy and autonomy.
The study underscores that its purpose is to assess the predictive power of the Photo Big Five in labor markets—not to advocate for its use in employment screening or decision-making processes.
Conclusion
The ability of AI to predict personality traits from facial images presents both opportunities and challenges. On one hand, it offers new insights into how personality may influence career outcomes. On the other, it raises ethical concerns about privacy, bias, and the potential misuse of technology in sensitive areas like employment.
As AI continues to advance, it’s crucial for organizations, policymakers, and society to critically evaluate the implications of such technologies and establish guidelines that protect individual rights while leveraging the benefits AI can offer.
