Personality shapes career choices in ways that go well beyond skills or salary. New research suggests it may also predict which professions attract people with what psychologists call "dark" personality traits — and which ones they consistently avoid.
The study, from researchers at the University of Copenhagen, analyzed data on more than 8,000 people across Denmark, Germany, and the United States. At its center is a psychological concept called the Dark Factor of Personality — or simply "D" — which measures the tendency to prioritize one's own interests over others, including through manipulation, aggression, or dishonesty. Think of it as a common thread running through traits like narcissism, psychopathy, and Machiavellianism.
Where dark personalities don't go
The clearest finding was about avoidance. People who scored higher on the Dark Factor were consistently less interested in social professions — teaching, nursing, therapy, counseling — and were also less likely to actually work in them.
The reason isn't hard to see. These jobs are fundamentally oriented around other people's wellbeing. As lead researcher, Ingo Zettler put it, social professions are "mainly about doing something for others — offering comfort, guidance, help or support — and this is at odds with the prioritization of one's own interests at the cost of others." People high in D are motivated by self-interest; professions built on service tend not to appeal to them.
Artistic roles — designers, musicians, creative professionals — were also somewhat less attractive to people with higher D scores, though the effect was smaller and, by the researchers' own admission, somewhat unexpected.
The more complicated picture
When it came to enterprising roles — managers, salespeople, executives — the findings got murkier. German data showed a positive relationship between higher D scores and interest in these positions. American and Danish data didn't show the same pattern consistently. The researchers interpret this as a sign that culture shapes how dark personality traits interact with career ambitions, and caution against generalizing too broadly.
The same caution applies to a small finding in Danish registry data linking higher D scores with realistic, trade-oriented jobs. The effect was minor, didn't replicate across countries, and the researchers were explicit about not over-reading it.
What this means — and what it doesn't
The researchers are careful not to turn these findings into a hiring playbook. Personality traits, including darker ones, can be relevant information in recruitment and leadership decisions — particularly for organizations that care about ethical standards and cooperative culture. But Zettler is emphatic that assessment tools need to be carefully designed and should never be used as the sole basis for a decision.
What the research does offer is a more nuanced view of why people end up in the professions they do. Skills matter. Salary matters. But personality — including the parts of it we don't often discuss openly — shapes career trajectories in ways that are consistent and measurable across cultures, even if the specifics vary.
The takeaway isn't that certain industries are full of bad actors. It's what motivates a person at a fundamental level that tends to pull them toward work that fits those motivations — and away from work that doesn't. That's true for prosocial traits and, as this research shows, for darker ones too.
