Somewhere in the last few years, without noticing, you stopped asking questions about the thing you know best. Not because you learned everything — nobody does — but because you crossed an invisible line where asking started to feel beneath you. The junior person asks how the system works. You explain how the system works. And in that quiet role reversal, something you'd never consciously agree to happened anyway: your competence became a wall between you and your own curiosity.

This isn't a character flaw, and it isn't arrogance in the cartoonish sense. It's a documented, replicable quirk of how humans handle status — and it has a name that sounds like an accusation but is really a diagnosis: the earned dogmatism effect.

The experiment that caught expertise closing minds

In 2015, Victor Ottati and colleagues at Loyola University Chicago published a series of studies in the Journal of Experimental Social Psychology with an unsettling design. They didn't study actual experts. They studied the feeling of expertise — and they manufactured it on demand.

In some studies, participants took a trivia test that was secretly rigged to be easy, or were told they had performed exceptionally well. In others, they simply recalled a situation in which they had acted as an expert. Then everyone answered questions about how open-minded they felt entitled to be — whether they should consider alternative viewpoints, listen to people who disagreed, entertain ideas that challenged their own.

The result held across studies: people who had just been made to feel expert endorsed more closed-minded, dogmatic attitudes than people made to feel like novices. Nothing about their actual knowledge had changed. A few minutes of induced confidence was enough.

Ottati's explanation is elegant and social rather than cognitive. We carry an unspoken norm that experts have earned the right to be dogmatic. The novice is expected to listen; the authority is permitted to pronounce. So when a situation casts you as the expert, you don't just feel knowledgeable — you feel licensed to stop considering alternatives. Closed-mindedness stops feeling like a vice and starts feeling like a privilege you've paid for.

Read that back slowly, because the implication is genuinely uncomfortable: open-mindedness isn't a stable trait you either have or lack. It's a dial, and the world turns it down every time someone calls you the expert in the room.

Overclaiming: when you "know" things that don't exist

A companion finding from the same year makes the picture worse. Stav Atir, Emily Rosenzweig, and David Dunning — yes, that Dunning — published research in Psychological Science on what they called overclaiming. They asked people to rate their knowledge of finance, then showed them a list of financial terms and asked which ones they recognized. Buried in the list were terms the researchers had invented — plausible-sounding phrases like "pre-rated stocks" that mean nothing at all.

The people who rated themselves most expert were the most likely to claim familiarity with the fake terms. Self-perceived expertise didn't just make people confident about what they knew; it made them confident about knowledge that could not exist. The feeling of mastery had detached from the territory and started vouching for the map all on its own.

Put the two findings together and you get the full mechanism. Feeling expert grants you social permission to stop listening (earned dogmatism), while simultaneously inflating your sense of what you already know (overclaiming). One closes the door; the other convinces you there's nothing on the other side of it.

The information gap that closed too early

Why does this kill curiosity specifically? The cleanest account comes from George Loewenstein's information-gap theory, one of the most durable ideas in the psychology of curiosity. Curiosity, Loewenstein argued, is the feeling produced by a gap between what you know and what you want to know. No gap, no itch. The crucial detail is that the gap is perceived, not actual. Your brain doesn't consult reality to decide whether you're missing something; it consults your self-assessment.

This is why expertise is uniquely dangerous to curiosity. A genuine expert has more unexplored frontier than anyone — every field's best practitioners insist the deep questions keep multiplying. But the feeling of expertise papers over the gaps. If your self-assessment says "I know this," the gap registers as closed, the itch never arrives, and the question never forms. You don't decide to stop being curious about your own field. You simply stop feeling the sensation that starts the process.

Meanwhile, everyone around you cooperates with the shutdown. Colleagues route questions to you, not past you. Asking a basic question now carries a status cost that it never carried when you were new. The environment and the psychology reinforce each other, and the result is a professional who is most incurious precisely where they are most capable.

Beginner's mind is a practice, not a personality

Zen teacher Shunryu Suzuki compressed all of this into one line decades before the experiments: "In the beginner's mind there are many possibilities, but in the expert's mind there are few." The Japanese term is shoshin — beginner's mind — and it's often misread as a vague invitation to stay humble. The research suggests something more precise: it's a countermeasure. If feeling expert closes the information gap artificially, then deliberately adopting the stance of a beginner reopens it artificially. You're not pretending to know less. You're correcting a known bias in your own gauge.

There's encouraging evidence that this stance can be cultivated and that it pays off. Research on intellectual humility — notably by Tenelle Porter and Karina Schumann — finds that people who more readily acknowledge the limits of their knowledge show greater motivation to learn and more willingness to seek out views that oppose their own. Intellectual humility isn't self-deprecation; it's accuracy about your own map, and accuracy is learnable.

The practical insight from Ottati's work is that the trigger is situational. You become dogmatic when a situation casts you as the expert. Which means you can counter-cast yourself. Every time you deliberately take the novice role — asking the basic question, sitting in a class where you're the slowest person, saying "I don't actually know" out loud — you revoke the license before it takes effect.

Your next moves

  • Write three questions you can't answer about the thing you know best. Do it today, on paper, in your actual domain of expertise. If it takes longer than you expected, that difficulty is the earned dogmatism effect made visible — the gaps are there; your gauge stopped reporting them.
  • Ask one "beneath you" question this week. In your next meeting, ask a question you feel you should already know the answer to. You're not just gathering information; you're practicing taking the novice role in a room that casts you as the authority.
  • Date-stamp your knowledge. Pick a core belief in your field and ask: when did I last actually update this? If your understanding of something is essentially the version you formed years ago, spend twenty minutes tonight finding what's changed since.
  • Run an overclaiming audit on yourself. Next time you feel that warm flicker of recognition at a term or concept, pause and try to define it in one sentence before nodding along. Familiarity and knowledge feel identical from the inside; this is the two-second test that tells them apart.
  • Be a true beginner at something unrelated. Take one class — pottery, a language, climbing — where you are visibly the worst person in the room. The point isn't the skill. It's re-experiencing what not-knowing feels like, so you can recognize its absence back home.

Keep the gauge honest

The hard part of all this is that the earned dogmatism effect leaves no sensation behind. Closed gaps don't itch — that's the whole problem. What helps is keeping a running record of your open questions, because a written question is a gap your gauge can't quietly paper over. That's what Curiokit is built for: a place to capture the questions you can't yet answer — including the humbling ones about your own field — and return to them before the feeling of knowing seals them shut.
