Most of us have been stuck in the same loop: you lay out the evidence, you explain yourself a third time, and the other person only grows more certain that they are right and you are wrong. In a seven-and-a-half-minute video published in October 2026 on her channel The Holistic Psychologist, Dr. Nicole LePera takes that frustrating moment apart. Her argument is that reality is not a fixed set of facts that everyone receives the same way, but something each person builds through the lens of their own history and beliefs. From there she offers a practical path: recognize when a belief has hardened into identity, stop expecting proof to dislodge it, notice how much energy you are pouring into the attempt, and practice what she calls the both-and method, which lets two things be true at once without a winner. The talk is brief, but it reframes a problem most people experience as a personal failure into something closer to a structural fact about how minds work.
LePera is careful about the word. She is not using "delusional" as an insult for anyone who disagrees with you. Her working definition is specific: "a habit of holding firm to fixed beliefs that aren't true, that aren't supported by reality, and that can't be changed by no amount of proof, facts, or evidence" (1:06). The key ingredients are rigidity and immunity to evidence. An opinion can be wrong and still be the ordinary, movable kind of opinion that changes when someone shows you something new. Delusion is different because the evidence stops mattering.
That distinction matters because it changes what you do next. If you treat a rigid belief as an ordinary disagreement, you will keep bringing better arguments to a conversation that has stopped being about arguments. LePera names this trap directly, admitting it is one she has fallen into herself. People "think that if they just present more evidence or if they overexplain or if they use so much energy trying to get someone to see something that eventually they'll see it." The video's answer is blunt: they won't, at least not because of you.
She also makes clear that delusion is not confined to dramatic cases. Her opening frame is an ordinary argument with a sibling, a partner, or someone close to you, the kind of exchange most of us have had. The point is that the mechanism underneath is familiar, and it shows up in everyday relationships long before anyone would reach for a clinical label.
This is the spine of the talk, and it is where LePera asks her audience to challenge an assumption most of us hold without noticing. Many people believe there is one objective reality, and that disagreement is simply a matter of someone being wrong about it. She asks viewers to consider how two people can live through the exact same event and come away with "completely different interpretations and meanings" (1:39). If there were only one reality being received, that should not happen.
"We don't see things as they are. We see things as we are."

Her explanation is that we never experience the present moment raw. We experience it "through a lens of our past," combined with what is actually happening now. Her term for that lens is bias, which she describes as "all of the preconceived beliefs that we already carry." Her shorthand is a simple equation: "Our preconceived beliefs and our past experiences equal the reality that we are living" (2:16).
What makes this more than a platitude is that she gives a way to test it. Tell several different people about something that happened to you, she suggests, and listen. Each will likely offer a different opinion or feedback about the same event. The variation is not noise. LePera argues that it reveals something about the listeners. Their responses, she says, "will often be confessions about what they think of life, what they think of others, and even what they think of themselves" (3:24). In other words, when someone reacts to your story, they are also telling you about the filters they bring to it.
For anyone who has ever felt blindsided by a family member's account of a shared childhood, this is a useful reframe. The disagreement is less a dispute over a fixed past and more a collision of two autobiographies, each holding its own record of the same scene.
The second major idea in the talk is that advice is rarely neutral. LePera asks viewers to notice a pattern: "every time someone gives you advice, they sound more like they're giving advice to themselves" (3:37). Her explanation is that people speak from their own experience and circumstances, so the counsel they offer is often what they wish someone had told their younger self. The suggestion is that the person across the table is revisiting a past decision through you.
This is a generous way to hear unsolicited advice, and it also explains why it can feel so insistent. Strongly opinionated advisers, she notes, are often "super passionate about their opinion." When you offer a different perspective, they may argue or keep pushing their side, because your alternative quietly threatens the story they have built about their own life. Her point is not that the advice is worthless. It is that you can understand the advice as information about the adviser before you decide whether it fits your situation.
The practical consequence is that you can stop reading their insistence as a verdict on you. Their certainty may have far more to do with their history than with your choices.
This is where LePera's account of delusion becomes most specific. An opinion, she explains, is "just a held belief," and opinions "can be flexible and they can even change." The trouble begins when an opinion becomes part of who someone believes themselves to be. At that point it hardens. In her words, the belief becomes part of a person's "identity, of their self, of who they believe themselves to be," and it turns into "a more rigid belief" (4:40).
Her description of what happens next is the emotional heart of the video. If a person's perception is denied by someone with a different view, they "feel like they're under attack, like they're not real, like they're maybe not there at all." For some people, she says, "it can end up feeling quite literally in those moments like we don't exist." This reframes what looks like stubbornness. When a belief is fused with identity, challenging the belief feels like challenging existence. No wonder evidence bounces off.
Understanding this does not require you to diagnose anyone. It gives you a way to recognize when a conversation has moved from disagreement about facts to a defense of selfhood, and to adjust your expectations accordingly. You are not going to out-argue someone who is protecting who they think they are.
LePera's remedy begins with a shift in goal. She asks viewers to release "the idea that you have to be right and someone else has to be wrong." From there she introduces what she calls the both-and method, and she frames it as central to healing: "Once you use the both and method, you truly begin healing." The core insight, as she puts it, is that "one person doesn't always have to be right" and that "two things can be true" (6:26).
The power of this is that it removes the win condition. If your aim is to make the other person see it your way, every exchange becomes a contest you cannot win on their terms. Both-and lets you hold your own perception as valid while acknowledging theirs as real for them, without demanding that either erase the other. The description accompanying the video frames this as a way of staying grounded "without needing to win the argument," which is the practical payoff.
Notice what the method does not require. It does not ask you to agree with a belief you think is false, or to pretend a clearly harmful account is fine. It asks you to stop treating the disagreement as a referendum on whether your reality exists at all.
LePera closes with a set of practical moves that follow from everything above. The first is to notice the cost. She asks viewers to pay attention to "how much time you spend feeling upset because someone thinks something about you," and how much effort they give "to people who have shown you that they're committed to not understanding you or a situation." She also points to the body, observing how "much your cortisol spikes when you continue to seek validation from a person who is only willing to validate their own perspective."
The second move is to stop expecting validation from the one person who cannot give it. That does not mean cutting someone off. It means redirecting the need for recognition toward sources that can provide it, and recognizing when a relationship keeps offering only a mirror of the other person's view.
The third is the one she ends on, and it is the most durable: your own perspective does not need outside approval to be legitimate. As she puts it, "your own thoughts, feelings, and opinions are valid even if other people don't share them. They're valid simply because you have them" (6:47). For someone who has spent years trying to be recognized by a person who will not recognize them, that sentence can be the beginning of a different relationship with themselves.
LePera leaves viewers with three questions she invites them to answer in the comments: which situations pull you into needing to be right, how much energy you are noticing you spend trying to get someone to see what they may not be willing to see, and what it would look like "to begin to trust your own perspective without needing someone else to agree with it." Those are good questions to take into your next hard conversation, whether or not you ever post an answer.
If this talk landed for you, start small. Pick one recurring disagreement and ask yourself whether it is an ordinary difference of opinion or a belief that has fused with someone's sense of self. Notice whether more evidence has ever moved them. Try the test LePera suggests: tell a few different people about the same experience and pay attention to what their responses reveal about them. Then practice the both-and move in a low-stakes exchange before you bring it to a painful one. The aim is not to win, and not to be endlessly agreeable. It is to remain anchored in your own reality while letting someone else keep theirs.
