Have you ever wondered why some people seem to breeze through job interviews while others, equally qualified, struggle to make an impression? It’s a question that’s both personal and systemic, and it’s one that a 2020 study in the Journal of Personality and Social Psychology tackles head-on. The research suggests that what interviewers often mistake for competence is actually overconfidence—a trait more commonly found in higher-class candidates. But here’s the kicker: it’s not that working-class candidates are less capable; they’re simply less likely to inflate their abilities. This raises a deeper question: Are job interviews really measuring skill, or are they just rewarding a certain style of self-presentation?
The Confidence Trap
What makes this particularly fascinating is how the study reframes our understanding of confidence. The authors use the term miscalibrated to describe individuals whose self-assessment doesn’t align with their actual performance. In my opinion, this is where the real insight lies. Overconfidence isn’t just a personality quirk; it’s a social signal shaped by class, culture, and upbringing. Higher-class candidates often grow up in environments where self-promotion is encouraged, even rewarded. They learn to project certainty, even when the evidence is thin. Working-class candidates, on the other hand, are often taught to value modesty and caution. Bragging? That’s a social risk they’re trained to avoid.
From my perspective, this dynamic reveals a troubling truth about hiring practices. Interviewers aren’t just evaluating skills; they’re interpreting signals. And when overconfidence is mistaken for competence, the system inadvertently favors those who’ve had the privilege of learning how to perform it. This isn’t about ability—it’s about style. One thing that immediately stands out is how this perpetuates class inequality, not through overt bias, but through a subtle misreading of what confidence really means.
The Hidden Rules of Class
Class isn’t just about income or education; it’s about the unspoken rules we internalize. What many people don’t realize is that these rules govern how we present ourselves in high-stakes situations like job interviews. For higher-class candidates, confidence is a familiar language. They’ve had more practice advocating for themselves, more opportunities to take up space without fear of judgment. Working-class candidates, meanwhile, often learn to qualify their statements, to wait for permission, to avoid appearing arrogant. These behaviors aren’t signs of weakness—they’re adaptations to different social norms.
If you take a step back and think about it, this isn’t just about individual behavior; it’s about systemic expectations. Interviews often reward candidates who can narrate their experiences with polish and certainty. But what this really suggests is that the system is selecting for a particular kind of self-presentation, one that’s more accessible to those who’ve been taught to perform it. It’s not that working-class candidates can’t do the job—it’s that they’re less likely to package themselves in a way that aligns with interviewer expectations.
The Illusion of Merit
Here’s where things get really interesting: the study isn’t just critiquing candidates; it’s critiquing the hiring process itself. Overconfidence, when rewarded, becomes a proxy for competence. A detail that I find especially interesting is how interviewers often conflate decisiveness with leadership or clarity with potential. These are soft skills, yes, but they’re also heavily influenced by class-based behaviors. When interviewers prioritize these traits without grounding them in job-relevant evidence, they’re essentially selecting for privilege, not merit.
This raises another point: unstructured interviews are particularly vulnerable to this bias. Without consistent questions or clear scoring criteria, overconfidence has free rein. A structured process, on the other hand, forces interviewers to focus on measurable skills rather than intuitive impressions. Personally, I think this is where the real change needs to happen. Hiring shouldn’t be a performance; it should be an assessment of ability. Work samples, practical tasks, and role-specific questions can help level the playing field, though they won’t solve class inequality on their own.
The Wrong Takeaway
One of the most frustrating responses to this research is the idea that working-class candidates should just be more confident. This completely misses the point. It’s not about teaching people to overinflate their abilities; it’s about rethinking what we value in candidates. Confidence is useful, but confidence without evidence is just noise. Employers need to stop mistaking self-assuredness for skill and start questioning why certainty is so often rewarded in the absence of proof.
What this really suggests is a moral contradiction in hiring cultures. Companies often claim to value humility, honesty, and self-awareness, but their practices reward the opposite. This isn’t just unfair to individual candidates—it shapes who gets promoted, who’s seen as leadership material, and who’s constantly asked to prove themselves. Over time, these small biases compound into large disparities in opportunity.
Beyond the Interview Room
The study’s implications go far beyond hiring. It’s a reminder that social signals are deeply embedded in systems we often assume are meritocratic. Interviewers aren’t foolish; they’re operating in a socially dense environment where cues are easily misinterpreted. But that’s precisely why we need to be more critical of those cues. When we reward overconfidence, we’re not just selecting for a certain type of candidate—we’re reinforcing a certain type of privilege.
In my opinion, the solution isn’t to train working-class candidates to perform confidence; it’s to train interviewers to recognize when confidence is being used as a substitute for competence. This means rethinking what we mean by “potential” and “fit.” It means anchoring evaluations in job-relevant evidence rather than intuitive impressions. And it means acknowledging that the way someone presents themselves is shaped by forces far beyond their control.
As I reflect on this research, what strikes me most is how much we still have to learn about the hidden dynamics of opportunity. Job interviews aren’t just tests of skill—they’re tests of calibration, ease, and entitlement. The working-class candidate isn’t less capable; they’re just less likely to perform the kind of certainty that interviewers often mistake for competence. And in a system that rewards the wrong signals, that difference can be everything.
