Who you are fluctuates every single second | Lisa Feldman Barrett
We created this video in partnership with Unlikely Collaborators ► https://www.unlikelycollaborators.com/
Ask five people who you are. You might get five different — and equally true — answers. Psychologist Lisa Feldman Barrett explains.
The Perception Box is a framework developed by Elizabeth R. Koch. Her upcoming book, The Perception Box, is now available for pre-order ► https://www.amazon.com/dp/1668056887
Psychologist Lisa Feldman Barrett argues that traits like introvert, extrovert, dismissive, or engaged aren’t fixed properties sitting inside a person — they’re descriptions of a relationship. When Barrett interrupts a conversation out of enthusiasm and someone else experiences her as rude, she argues both experiences are equally real, not because one interpretation wins, but because identity itself is relational rather than internal.
That means how extroverted, rude, or engaged you seem shifts depending on who you’re with, how much you’ve slept, and whether you’ve eaten. Personality isn’t sealed behind your skin — it’s built moment to moment, in relation to the people around you. Which means they have more influence over who you are than you might think, and you have more responsibility for who they become.

I speak tow languages – one native, the other OK – and I'm absolutely a different person depending on which language I'm speaking … personality is very contextual.

So true! I had this conversation eith someone about introversion vs extroversion and I thought about MBTI for many years but when they said "it depends who I'm with" my mind was blown, it's so true!

Everybody constructs their own image of someone else. This construction is based on prior experiences/beliefs; and their individual experience with the individual.

Hearing your story about interrupting out of enthusiasm—and what you tell your daughter—made me want to reflect this back to you:
Enthusiasm can be the false egoic mind screaming to be heard. We have two ears so we can listen twice as much as we speak.
When that urge arises and hijacks the interaction, pause. Watch for where it comes from instead of speaking, and ask why it's showing up when your current role is to listen.
When the person in front of you is speaking, they are driving the car—you don't kick them out of the seat to drive.
Be still, be peace, listen.
You encourage your daughter to seek out others, yet talking over people blocks the very perspectives meant to help us grow.
"Do not do as I do, do as I say."
Teacher, student—be the student teacher.

Calling identity relational and claiming you fluctuate every second based on who you are with is just a sophisticated way of admitting you have no core. If your personality shifts with every room, you are not an individual, you are a reactive mirror. Reading Glow They Never Saw by Zael Veynor exposed how modern psychology keeps you trapped in social feedback loops. True sovereign agency is forged in absolute solitude where external reflections lose all power over you.
@MaryGrcae-b5v
November 12, 2026 at 6:54 am
The idea that we need to curate our social environments to bring out the best version of our fluctuating identity is just another performative cage. As Zael Veynor breaks down in Glow They Never Saw, outsourcing your self worth to relational contexts ensures you will never possess true internal authority. Real power begins when your baseline no longer depends on who is standing next to you.
@JenerosePacaldo
November 12, 2026 at 6:54 am
No wonder people feel so fractured when every interaction pulls them into a different version of themselves. The moment you step into the dark room and anchor your core in absolute solitude, exactly as Zael Veynor teaches in Glow They Never Saw, you stop caring how your personality fluctuates across rooms because your foundation becomes completely unshakeable.

Can someone out there pretty please invite Lisa, Hannah Fry and Hank Green to a panel discussion on this topic? Hank and Hannah have dropped hints during online dialogues suggesting they're coming to similar conclusions (I like Hannah's, "are we just fiction?" humourous posit). And come from three different approaches. I would enjoy that, and their interactions.

Everything that harms our well-being begins as an idea in someone's head before it becomes a real problem in the world. Most founders of major religions tried very hard to teach people this truth. However, people back then laughed and called them crazy, and people still laugh at this idea today.

This is immediately why all ones personal problems only exist because of interpersonal relations, if you feel insecure it's because of your relation to others in the world. Takeaway from The Courage to Be Disliked, great read!

00:37 There are people who have trouble reading facial expressions, and there are people who generally have trouble with timing in conversations. There are specialized books on these topics, so this conclusion is only partially correct at best.

Through others I have learned system abuse and concealment tactics through bullying cliques. I have learned not many authentically or genuinely connect through unconditional positive regard to maintain integrity. I have learned not many live accountability and responsibility for wellbeing. I have learned so many revelations of how to reveal "Unloved". I have learned that girls make other girls suffer and indirect aggression is their gender expression. What does that say about me in the social? I have learned how workplaces bully and lie. I have learned that so many emotionally, socially and academically challenged people say they are the best! I have learned collaboration is not ethical and done with right and wrong it's simply corruption and corroborating for an alibi approach to living. I have learned that people determine others because they don't have deeper growth mindset nor listening skills. Why should I become someone through all that reduction and selfish demands to overcome my independence and curiosity?

The whole premise perfectly destroys the theological cope of an eternal, unchanging "soul". Dualists love to pretend we have some magical, static essence floating inside us, but neuroscience shows that identity is just a momentary, fluctuating set of signals in the brain making action plans based on past statistics. Your personality literally changes based on your environment, how much sleep you've had, and who you're interacting with. Acting like you have a permanent ghost driving your meat suit when your entire sense of self is just deterministic biological meaning-making is honestly hilarious. We’re highly situated, physical systems, not trapped spirits.

We're always changing.. different from moment to moment. Depending on your state of being and circumstances creates different experiences that can be perceived by you and other observers.. How you respond to someone..is then filtered through your own degree of understanding of whats happening..then interpreted into a meaning of Who you think they are at that moment . We influence each other so deeply.. We dont notice it

"I'm experiencing myself as engaged. Another person is experiencing me as rude, and that's what's real." Lisa Feldman Barrett's admission names a blind spot in driven people: they judge themselves by intent while everyone around them lives with the impact. The test is whether you could say, without guessing, how the person closest to you feels in your presence when you are under pressure.

A small repair for the interruption example: “I jumped in—please finish your point.” Then leave the pause open and listen. It gives the other person their turn back while keeping the conversation about what just happened.

No. I’ll-informed hypotheses, slander and biases exist in our thoughts but do not define reality, much less something as ill-defined and nebulous as someone’s identity, the ‘who they are’. Sorry but the title of this video together with the first few minutes are so patently rage-click-bait that I’m not watching the rest. For what it’s worth, someone who thinks I’m rude when I’m enthusiastic and engaged is someone I steer clear of because that is someone who believes ill of me without taking other ideas and perspectives into account. And therefore that person is dangerous, depending on circumstance. To me, it’s possibly rude to keep interrupting when you’ve been asked to listen to the end but even then, urgent circumstances might say otherwise. I agree with Jean Paul Satre that it’s a form of hell, taking other people’s opinions as defining reality. They do not, no more than taking people’s biases against women (to give one example, and my lifelong problem) as the truth.

This talks to the destructiveness of backbiting in annihilating your identity by changing what other people see you as. Perhaps that’s part of why the Baha’i Faith teaches that backbiting is a sin second only to murder.

The interrupting example made it click for me — I experience myself as enthusiastic and engaged, and the other person experiences me as rude, and both are real. Asking how extraverted you are when you're rested at a dinner party versus with strangers you don't know is a much better question than any fixed label. We really aren't the sole authors of who we are.

Einstein figured it out. Everything is relative, what you see or experience just depends your current frame of reference.
As someone who's brain is like a universal train station jam packed with incessantly deep, abstract thoughts. There are people who intentionally interrupt, I don't do it intentionally. My brain is processing a shit load of data, while analyzing it and predicting what to say as well as what is and will be said. Gotta love the combined type ADHD, ausbergers, gad, and depression value meal life gave me.
Whether someone thinks I'm rude doesn't matter to me because I catch myself interrupting and immediately apologize and give back the convo.
It's hard to talk to people about my likes and thoughts anyway. I think VERY deeply, depressingly deeply, about physics, reality, compute, etc with a tiny sometimes hard to find shut off switch. Whenever I try to be myself, eyes just glaze over and I give up.
Being intelligent in an unintelligent world sucks 😂

"In many cultures, we have the idea that a person is bound by the skin"…luckily many of us were able to read/hear Alan Watts back in the 1960s explaining how that is not so, and then maybe going on to study Zen or humanistic/existential/transpersonal psychologists, etc…..great to see those ideas coming back to the forefront again……..also, sometimes, if you did not "interrupt" a person you wouldn't get a word in edgewise, or the monologue would go on and you'd forget what the thing was you wanted to respond to several minutes ago…just sayin'….

According to the African philosophy Ubuntu, a person is a person through other people.
I am, according to me, just one day long song in a soundtrack of life, and I try to do my part to make the whole better by my efforts. I am we, just one of many who inhabits this vessel, and I live just as much for those to come as I do for myself.

The illusion of ego: thinking of yourself as mostly a brain in a body vehicle, a consecutive, inherent story; instead of thinking of yourself as mostly a body taking one breath after another until stopping one day, with a brain as a tool to find enough resources to keep breathing as long as possible.
My tool isn't that good at english… But if you see yourself as a combined system of a body with a mind, it makes sense that e.g. you won't be that happy for that long after winning the lottery. After winning the lottery you just will continue breathing, maybe in a more luxury car, but still all you do is hallucinate a background story while continuing breathing, it doesn't change that much for your body.

Why we need "specialists" and "intelectuals" to tell us these things? This is a no brainer. Of course what people think about you without knowing you at all, tells you more about that person than about yourself. I realized that many years ago when people ask me if I was from south america or asian. I am neither and also couldn't be both. Asians and south american people are quite different. So of course people were asking me based on their preferences. If they prefer asia they would ask if I m asian ans if they prefer south america they would ask if i m south american. I dont have a degree to come to this conclusion so why are these topics in a channel that is supposed to make us think big? This seems like kindergarden pasychology
