There’s a particular kind of confidence gap that nobody really talks about. The one between how secure you actually feel and how secure you appear to others. Most people assume those two things are roughly in sync. They’re not. You can feel perfectly fine about yourself and still be broadcasting uncertainty to every room you walk into, simply because of a handful of habits you’ve probably never thought twice about.
The frustrating part is that these habits are completely automatic. They’re not signs of weakness or deep-seated insecurity. They’re just your nervous system doing what it’s wired to do under social pressure. The problem is that the people around you don’t know that. They’re not reading your internal experience. They’re reading your posture, your hands, and the way you frame your sentences. And they’re forming judgments before you’ve said ten words.
Three patterns in particular reliably create that impression. They show up in job interviews, first dates, presentations, and ordinary conversations. They’re common enough that most of us do at least one of them regularly without realizing it.
1. Collapsing Your Posture Under Pressure
There’s a very specific thing that happens to the body when you feel watched, judged, or uncertain. The shoulders creep up. The spine curves forward. The arms fold across the chest or pull in tight. It’s a physical contraction, and it happens fast, often before conscious thought catches up.
Researchers have identified two distinct nonverbal dimensions associated with power: high-power postures are defined by expansiveness and openness, while low-power poses are based on contractive and closed positions, like sitting tensely with hands held tightly in the lap. That contrast, open versus closed, expansive versus contracted, is something other people read almost instantly.
Princeton psychologists Janine Willis and Alexander Todorov found that all it takes is a tenth of a second to form an impression of a stranger from their face, and that longer exposures don’t significantly alter those impressions. In that brief moment, observers are already judging trustworthiness, competence, and dominance. Closed posture lands in that window. And once that first impression is made, it shapes how everything else you say or do gets interpreted.
Research on posture suggests that expansive and open poses can increase feelings of power and confidence, while the slumped seated posture is consistently associated with sadness and fatigue. The reverse is also true: contracting inward tends to reduce your sense of your own authority, which can then make the posture worse. The loop feeds itself.
The practical correction is simpler than it sounds. You don’t need to strike a pose or perform confidence. You just need to stop actively contracting. Let the shoulders drop, keep the spine loosely upright, and resist the urge to fold your arms across your chest when you feel exposed.
2. Self-Soothing Fidgets That Others Can’t Ignore
The small, repetitive, almost invisible movements – adjusting a watch, spinning a ring, touching the side of your neck, tapping the same finger against your palm – are called self-soothing behaviors, and they work. They genuinely calm your nervous system in moments of stress. The problem is that they work for you, not for the person watching you.
Fidgeting is a prominent observable movement behavior in patients with social anxiety disorder (SAD) and persons with subclinical social anxiety and arousal. While prior research had explored its role as an indicator of internal states like anxiety or engagement, less attention had been paid to how observers interpret fidgeting when forming personality impressions. A 2026 study published in ScienceDirect changed that. The preregistered study investigated the impact of fidgeting on personality trait attributions, with 388 participants randomly assigned to view a short video of someone either fidgeting (with object manipulation, self-touching, or foot tapping) or remaining still. The results were striking: fidgeting significantly influenced perceptions across four major personality traits. Emotionality was rated higher for fidgeting individuals, while agreeableness, conscientiousness, and openness to experience were all rated lower.
Research has found a significant moderate association of social anxiety with behavioral discomfort, including fidgeting and trembling, across both interaction and speech tasks. That association is exactly the problem. Even if your fidgeting is just a habit rather than a signal of distress, observers are connecting those movements to anxiety and a lack of composure, consciously or not.
Across three studies collectively sampling over 4,100 individuals, researchers found that approximately one-third of people self-reported some degree of sensitivity to the repetitive, fidgeting behaviors of others. That’s a significant portion of any room you walk into. The behavior you barely notice in yourself is landing hard on a third of the people around you. The fix isn’t to freeze. Natural movement is fine. The goal is to notice when your hands are doing something repetitive and self-directed rather than expressive and outward. There’s a meaningful difference between using your hands to emphasize a point and quietly soothing yourself with your fingers while someone else is talking.
3. Verbal Hedging That Pre-Defeats Your Own Points
Verbal hedging is phrases like “I might be wrong, but…” or “This is probably a silly idea, but…” or “I don’t know if this is relevant…” tacked onto the front of perfectly reasonable, well-considered statements. Most people do this with good intentions. They want to seem humble rather than arrogant, open rather than dogmatic, approachable rather than aggressive. What they’re actually doing is training the listener to expect something weak before they’ve heard a word of it.
Researchers investigated whether speakers can protect their reputation when making claims with low prior probability, exploring suggestions that speakers can protect themselves by hedging with evidential language, using weaker propositional attitudes such as “I suspect that…” Research found that indirect evidential claims such as “I suspect that…” did not allow speakers to hedge their bets: speakers asserting a falsehood paired with an indirect source claim still received a hit to their reputation in the eyes of their listeners. In other words, softening your statement up front doesn’t buy you goodwill if things go sideways. It just signals uncertainty from the start.
Confident speakers are more likely to be believed, and people favor speakers who make assertions over those marking their claims with hedging expressions such as “as far as I know.” Leading with a hedge is one of those embedded signals. The listener hears “I might be wrong, but” and their brain begins evaluating you as someone who isn’t sure of themselves, before they’ve absorbed a single word of your actual point.
This habit is worth examining separately from genuine intellectual humility. There’s a real difference between saying “I’m not certain about the numbers, but my read on this is…” – which is honest and specific – and reflexively pre-apologizing for every idea as a default. Research in clinical psychology has shown that social anxiety is most strongly linked to an increase in observable signs of anxiety, and that techniques helping individuals recognize their use of anxious behaviors like fidgeting and throat-clearing, and practicing eliminating them, may be especially beneficial. The attempt to protect yourself from judgment can end up triggering the very judgment you were trying to avoid.
What to Do With All of This
None of these habits mean anything is fundamentally wrong with how you carry yourself. They’re normal stress responses, deeply wired into human behavior. What makes them worth understanding is the gap they create between your actual confidence and the confidence other people perceive. That gap has real consequences – in how seriously your ideas are taken, how you’re read in high-stakes moments, and how people choose to engage with you going forward.
The good news is that none of these requires a personality overhaul. With awareness and practice, it’s possible to become more conscious of body language and make improvements. Research supports the finding that expansive and open poses can increase feelings of power and confidence, which means intentionally changing body language can also influence how you think and feel in the moment. Start with the one habit that resonates most. If the fidgeting rings a bell, try keeping both hands still and in view during your next important conversation. If the hedging is your thing, spend a week catching yourself before you add the pre-apology and just don’t. If posture is the issue, the most useful cue is simply to notice when you’re contracting and let your shoulders drop.
The Quiet Part
You’re not trying to perform confidence you don’t feel. You’re trying to remove the static that’s been getting between your actual self and how other people receive you. That’s a smaller job than it sounds, and it doesn’t require becoming a different person. It just requires noticing a few things you’ve been doing on autopilot for years.
The habits covered here are common precisely because they feel protective. Hedging feels polite. Fidgeting releases tension. Curling inward feels safe. None of that is wrong. The only thing worth changing is doing them reflexively, without realizing the signal they send. Catch the habit, pause, and choose differently. That’s the whole job.
