Confidence is one of those things we’re told we either have or we don’t. Some people walk into a room and immediately command attention, while others fade into the background. It seems obvious who put it all together, right?
But here’s what I learned. that unwavering confidence isn’t always what it seems. Some of the most confident people on the surface, who appear fearless, charismatic, and in control, actually struggle with deep-seated insecurities.
The tricky part. They are really good at hiding it. In fact, their insecurities don’t manifest in the way you’d expect. Instead, it is revealed through subtle behaviors that most of us overlook.
If you’ve ever wondered why someone acts a certain way despite appearing confident, or if you’ve had moments of self-doubt despite seemingly getting along with others, this might explain why.
Here are eight subtle behaviors that often indicate underlying insecurities, even in the most outwardly confident people.
1) They have to constantly prove themselves
Truly confident people don’t feel the need to remind everyone how confident they are. But those who are secretly insecure. They often go out of their way to prove themselves, be it through their achievements, knowledge, or even social status.
They may casually mention their successes in conversations, point out their skills, or subtly compete with others, even when no one is keeping score. It’s not always obvious braggadocio, but there is a certain energy of needing validation from the outside world.
Deep down, they’re not trying to impress you, they’re trying to reassure themselves. If they stop proving themselves, they fear they may not be enough.
2) They struggle for criticism
When someone’s confidence is strong, they can respond without taking it personally. But for those who are secretly insecure, even the slightest criticism can feel like an attack.
I used to be like that without realizing it. A former boss once gave me some constructive feedback on a project, and instead of seeing it as an opportunity for improvement, I got embarrassed and defensive. I spent the rest of the day replaying the conversation in my head, trying to justify why my job was actually okay the way it was.
Looking back, I wasn’t sad because the reaction was unfair. I was upset because deep down I was already questioning my abilities and hearing it from someone else confirmed my worst fears.
People who seem confident but struggle with insecurity often react this way. They may deflect criticism, make excuses, or even get irritated when someone points out a flaw. Not because they believe they are perfect, but because they fear they are not good enough.
3) They must always be right
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
– Stephen Hawking
People who are truly confident don’t feel the need to win every argument. They can admit when they are wrong, change their minds when new information is presented, and engage in discussions without needing to dominate them.
But when someone seems confident but is secretly insecure, admitting they’re wrong can seem impossible.
They will debate endlessly, double down on weak points or move the goalposts just to avoid conceding. It’s not about the topic itself, but what being “wrong” represents to them.
If they admit their fault, even on something small, it will destroy the image they have carefully created for themselves.
Insecurity makes people cling to certainties, even when it’s clear they don’t have all the answers. The need to be right is not about proving something to others, but about protecting yourself from doubt.
4) They overcompensate with perfectionism
Perfectionism isn’t just about having high standards, it’s often a defense mechanism. Studies have shown that many perfectionists struggle with deep feelings of inadequacy, using their relentless pursuit of perfection to mask self-doubt.
Someone who appears confident but is secretly insecure may obsess over the smallest details, refuse to delegate assignments, or procrastinate because they fear their work won’t be “good enough.”
To the outside world, they seem disciplined and driven. But beneath the surface, they struggle with an inner voice that tells them they’re a less-than-perfect failure.
It’s not just about getting things right, it’s about avoiding the embarrassment of getting things wrong. Even when they achieve something great, they rarely feel satisfied because their confidence is tied to external validation rather than true self-confidence.
5) They deflect with humor or sarcasm
Not all insecurities are a form of self-doubt, sometimes it feels like a perfectly timed joke. People who are secretly insecure often use humor or sarcasm to draw attention away from their vulnerabilities.
They can make fun of themselves before anyone else can, interrupt serious conversations with a joke, or turn any situation into something embarrassing.
On the surface, it seems like trust. they are quick witted, charming and never take things too seriously. But in reality, humor becomes a shield, a way to avoid uncomfortable truths or deeper feelings.
Having a good sense of humor is one thing, but when someone consistently uses it to avoid real conversations or hide their struggles, it’s often a sign that they don’t feel as secure as they seem.
6) They seek validation but pretend they don’t need it
Someone who is truly confident does not rely on external approval to feel secure. But when someone is secretly insecure, they often seek validation while doing everything they can to make it seem like they’re not.
They may subtly seek compliments, downplay their accomplishments in a way that inspires confidence, or be indifferent to praise while secretly needing to feel good about themselves.
Sometimes they will even act like they don’t care what anyone thinks, claiming they are above approval, when in fact they pay close attention to how others perceive them.
It’s a delicate balancing act between wanting to be seen and appreciated, but fearing that their need for validation makes them weak.
Instead of openly acknowledging this need, they mask it behind expressions of indifference or self-doubt, hoping that someone will see through it and provide reassurance that they won’t ask for directly.
7) They have difficulty marking others
Confidence isn’t just about feeling good about yourself, it’s also about being safe enough to appreciate others without feeling threatened.
But when someone appears confident but struggles with insecurities, they often find it difficult to genuinely celebrate the successes of others.
They may downplay another’s accomplishments, offer half-hearted compliments, or quickly shift the conversation to themselves. In some cases, they may even feel an unspoken sense of competition, as if someone else’s victory somehow makes them less successful in comparison.
It’s not that they don’t want to be happy for others, it’s that deep down, every success they witness reminds them of their own self-doubt.
Instead of feeling inspired, they feel inadequate, like they’re falling behind in a race that no one is really running.
8) They keep people away
Real confidence allows for real connection, because when you feel safe in yourself, you’re not afraid to be fully exposed. But those who are secretly insecure often keep others at arm’s length, even if they seem sociable and outgoing.
They may avoid deep conversations, deflect personal questions, or maintain a carefully crafted version of themselves that never reveals too much. They can be the life of the party, the person everyone admires, but still feel isolated because they don’t let anyone get close enough to see the cracks beneath the surface.
Fear is not only rejection, but exposure. If someone gets too close, he can see the doubts, the imperfections, the things that don’t match the confident image he portrays.
And for someone who ties their self-esteem to that image, letting people in is considered the biggest risk.
Bottom line
If you recognize yourself in any of these behaviors, you are not alone. Many people who seem most confident harbor doubts they rarely admit, even to themselves.
The good news is that true self-confidence isn’t about perfection, it’s about self-acceptance. It’s about recognizing where the insecurity is manifesting and working through it instead of covering it up.
Start by noticing when you feel the need to prove yourself, deflect compliments, or avoid vulnerability. Ask yourself: Am I acting out of true confidence or fear? Will letting go of this need make me feel freer?
Growth doesn’t happen overnight, but self-awareness is the first step. The more you learn to accept who you are, flaws, doubts, and all, the less insecurity you have about yourself.
And this is where real trust begins.
