Intellectual humility — the willingness to consider you might be wrong — turns out to be a better predictor of being right than raw intelligence is, and the people who score highest on it aren’t the ones who know the most, they’re the ones who hold their beliefs most loosely.
There is a particular cognitive style that turns out, on the available empirical research, to be one of the more reliable predictors of accurate judgment across a wide range of tasks. The style is not, on close examination, the one the wider culture has been calibrated to admire. The wider culture has been calibrated to admire confidence, decisive opinion, and the visible production of correct answers under pressure. The style that actually predicts accuracy is structurally different. The style involves holding one’s beliefs more loosely than the people around one, and being genuinely willing, in real time, to entertain the possibility that those beliefs might be wrong.
The cognitive trait that captures this style has a technical name in the contemporary psychological literature. The name is intellectual humility. The trait has been studied with increasing precision across the last fifteen years, and the studies have, on close examination, produced a consistent finding that the wider culture has not yet adequately absorbed. The finding is that intellectual humility predicts accuracy on most judgment tasks better than raw intelligence does, and that the people who score highest on it are not, in most cases, the ones who know the most. They are, more accurately, the ones who hold what they know more loosely than the people around them.
What “loose-holding” actually means, in cognitive terms
The loose-holding is not, on close examination, the same thing as not caring about being right. The intellectually humble person cares considerably about being right. The loose-holding is, more specifically, a particular structural feature of how the person’s beliefs are connected to their identity. The beliefs are connected loosely rather than tightly. The looseness allows the beliefs to be updated when new evidence arrives, without the person experiencing the update as a threat to who they are.
This is, on close examination, the structural feature that the wider research literature has identified as doing the work. A 2025 study from Boston College identified a specific facet of intellectual humility called “independence of intellect and ego.” The facet involves the structural separation of one’s sense of self from the specific beliefs one currently holds. The study found that this facet was the one most strongly associated with both better judgment outcomes and improved well-being. The structural separation, more accurately than the various other components of intellectual humility, was what allowed the person to update their beliefs without experiencing the update as a personal loss.
The independence is what the loose-holding actually consists of. The beliefs are still important to the person. The beliefs are just not, in any structural sense, the same thing as the person. The person can give up a belief and still be the same person on the other side of the giving-up. The person whose beliefs are tightly bound to their identity does not have this option. Any update to the beliefs, for them, is an update to the self. The updates, accordingly, are resisted, deflected, or selectively avoided in ways that the intellectually humble person is structurally less prone to.
What the empirical research has found
The empirical research on how intellectual humility predicts judgment accuracy has produced several findings worth attending to.
One of the more striking findings comes from research on the ability to distinguish true from false information in news headlines. A 2024 study by Prike and colleagues tested participants on their ability to discriminate between accurate and inaccurate news headlines while also measuring their intellectual humility on validated scales. The study found that intellectually humble participants were significantly better at distinguishing true from false. The effect was specific to discernment rather than to general skepticism. The intellectually humble participants were not, in other words, simply doubting everything. They were, more specifically, distinguishing accurately between what was true and what was not. The strongest single predictor was a sub-facet called Actively Open-Minded Thinking about Evidence, which produced a correlation of 0.48 with misinformation discernment.
A separate body of research has examined what happens when intellectually humble and intellectually arrogant participants encounter evidence that contradicts their existing beliefs. Research on polarized scientific topics has found that intellectually humble participants are more accurate at distinguishing correct from incorrect interpretations of evidence, and that the effect holds across the political spectrum. The intellectually humble participant is not, accordingly, just doing better at confirming what they already wanted to believe. The intellectually humble participant is, more specifically, doing better at evaluating the underlying evidence on its actual merits.
The structural mechanism the wider research has identified involves what cognitive scientists call metacognitive calibration. The intellectually humble person is, by structural design, better at assessing the accuracy of their own beliefs. They know more reliably when they are likely to be wrong. The knowing-when-wrong is what allows them to seek out additional information in the cases where it would most usefully change their conclusions, and to defer to other sources on questions where their own confidence does not warrant their current position.
Why intelligence alone is not sufficient
The structural reason that intellectual humility predicts accuracy better than raw intelligence is, on close examination, worth attending to. Intelligence, as standardly measured, predicts the ability to produce correct answers on tasks with known correct answers. The standardized measurement does not, by its structural design, particularly test the second-order question of how confident one should be about one’s own answers across a wide range of situations, including situations in which the correct answer is not currently available for verification.
The second-order question is, on the available evidence, where most of the variance in real-world judgment accuracy actually lives. The world rarely presents adults with multiple-choice tests where the correct answer is independently knowable. The world, more accurately, presents adults with situations of partial information, ambiguous evidence, and competing considerations that cannot be cleanly resolved by the application of raw cognitive horsepower. Navigating these situations well requires, in some real way, the additional skill of accurately knowing when one’s current beliefs are warranted by the available evidence and when they are not.
The additional skill is what intellectual humility, on the available research, structurally produces. Research by Leor Zmigrod and colleagues at Cambridge has found that intellectual humility is predicted by both intelligence and what the researchers called cognitive flexibility, with either being sufficient to produce the trait. The compensation effect is itself informative. The trait does not, on close examination, require any single underlying cognitive resource. The trait emerges, more accurately, from the use of whatever cognitive resources the person has, in service of the specific task of accurately assessing one’s own beliefs.
What the trait actually looks like, in daily life
The visible manifestation of intellectual humility in adult social life is, on close examination, almost invisible to the standard cultural register. The intellectually humble person is not, in most cases, doing anything dramatic in their conversations. They are, more accurately, doing several small things that the wider register has not been calibrated to particularly notice.
They are willing, when contradicting evidence arrives in real time, to update their position out loud. They are willing to say, in front of other people, that they had not previously thought about something in the way the new evidence suggests they should. They are willing to ask questions that reveal what they do not currently know, rather than performing a confidence they do not actually possess. They are willing to leave open questions open, rather than forcing resolution in directions that the available evidence does not actually support.
The willingness, in any single instance, looks small. The willingness, accumulated across thousands of conversations, decisions, and information-processing episodes, produces, by structural necessity, a person whose beliefs are, on average, considerably more accurate than the beliefs of an equivalently intelligent person who has not developed the willingness. The accuracy is not the result of knowing more. The accuracy is the result of having held what one knows more loosely, and having updated it more frequently and more honestly than the structural alternative would have permitted.
Why the wider culture rewards the opposite trait
The honest acknowledgment is that the wider culture, by its various selection mechanisms, tends to reward the structural opposite of intellectual humility. The wider culture rewards visible confidence. The wider culture rewards decisive opinion. The wider culture rewards the willingness to advance positions without the hedges that intellectual humility tends to attach to them. The structural result is that the visible leadership of most contemporary organizations is, on average, considerably less intellectually humble than the underlying population, because the selection process has been calibrated to filter out the people whose epistemic style would have produced more accurate judgments under conditions of uncertainty.
This is, on close examination, one of the more underappreciated structural costs of how the wider culture currently operates. The most accurate judges are, by structural design, not the ones being selected for the positions in which judgment accuracy matters most. The ones being selected are, more accurately, the ones whose confidence is most visible, regardless of whether the confidence is calibrated to the underlying accuracy. The selecting produces, in domains ranging from corporate leadership to political authority to media commentary, a structural over-representation of confident wrong people and a structural under-representation of intellectually humble accurate ones.
The acknowledgment this article wants to leave
The cognitive trait that predicts accurate judgment better than raw intelligence does is, on the available empirical research, intellectual humility. The trait is structurally distinct from both intelligence and from generic openness. The trait involves the specific cognitive style of holding one’s beliefs loosely enough that they can be updated when new evidence arrives, without the update being experienced as a threat to one’s identity.
The people who score highest on the trait are not, on close examination, the people who know the most. They are, more accurately, the people who hold what they know more loosely than the people around them, and who are willing to update their beliefs in real time when the underlying evidence suggests an update is warranted. The willingness is small in any single instance. The willingness, accumulated across decades, produces the structural feature that the empirical research has identified as one of the more reliable predictors of accurate judgment.
The wider cultural register has not yet, on the available evidence, fully absorbed this finding. The register continues, in most contexts, to reward visible confidence over calibrated confidence, and to treat the willingness to revise one’s beliefs as a sign of weakness rather than as the structural marker of accuracy it actually is. The not-absorbing is, in some real way, one of the more underappreciated structural costs the wider culture currently pays. The absorbing, modestly, is what articles like this one are calibrated to begin.
