You’ve probably seen the posters in corporate breakrooms or elementary school hallways. They usually have a picture of a mountain or a lightbulb with the word "YET" in giant, friendly letters. It’s easy to roll your eyes at the "growth mindset" craze, but behind the cheesy office décor is a book that actually changed how psychologists think about human potential.
In Mindset: The New Psychology of Success, Stanford psychologist Carol Dweck basically split the world into two camps. Not the rich and the poor, or the winners and the losers. Instead, she looked at the people who think they’re stuck with the brain they were born with and the people who think they can build a better one.
Honestly, it sounds like a self-help cliché. But the data Dweck gathered over decades shows that this tiny shift in how you view your own personality can be the difference between hitting a ceiling at age 25 or growing until you’re 90.
The Two Worlds: Fixed vs. Growth
Basically, Dweck found that we all carry around a "mindset" about our abilities.
A fixed mindset is the belief that your intelligence, character, and creative ability are static. You get what you get. If you’re "smart," you’re smart. If you’re "not a math person," you never will be. For these folks, every challenge is a test of their worth. If they fail, it’s not just a bad day; it’s a verdict on who they are.
Then you’ve got the growth mindset. These people see their basic qualities as things they can cultivate through effort and help from others. They don't necessarily think everyone is Einstein, but they believe everyone can get smarter if they work at it.
The real kicker? Dweck’s research suggests that even young kids fall into these categories. In one of her most famous studies, she gave 4-year-olds a choice: redo an easy jigsaw puzzle they’d already finished or try a harder one. The fixed-mindset kids chose the easy one. Why? Because they wanted to keep looking "smart." The growth-mindset kids thought the researchers were crazy for suggesting the easy one. They wanted the challenge.
The "Smart" Trap
We’ve all done it. You tell a kid, "Wow, you’re so smart!" or "You’re a natural at soccer!"

It feels like a good thing to say. It's not.
Dweck argues—and her studies back this up—that praising "talent" or "intelligence" actually pushes people into a fixed mindset. It makes them afraid of losing that label. If I’m only good because I’m a "natural," what happens when I struggle? It must mean I’m not a natural anymore.
Suddenly, you start avoiding anything that might make you look like a fraud.
Take the case of Enron. Dweck often points to the disgraced company as the ultimate fixed-mindset culture. They obsessed over "talent." They recruited the "best of the best" and paid them huge bonuses just for being smart. The result? Employees were so terrified of looking incompetent that they hid mistakes, cooked the books, and eventually brought the whole thing crashing down.
Compare that to someone like Muhammad Ali. According to the boxing experts of his time, he didn't have the "natural" build or the classic style of a champion. He wasn't the fastest or the strongest on paper. But he had a growth mindset that bordered on obsession. He studied, he adapted, and he out-worked everyone else because he didn't believe his limits were permanent.
What Most People Get Wrong (The False Growth Mindset)
Since the book exploded in popularity, it’s been misunderstood a lot. Dweck actually had to come out and address what she calls the "false growth mindset." A lot of parents and teachers started thinking a growth mindset just meant "praising effort." You see a kid fail and say, "Well, at least you tried hard!"
That’s not it.

Honestly, if a kid works hard and fails, praising the effort can feel like a consolation prize. It’s patronizing. A true growth mindset isn't just about trying hard; it's about trying new strategies. If the way you’re studying isn't working, "trying harder" at the same bad strategy is just a recipe for burnout. Dweck emphasizes that the goal is the learning, not just the sweat.
The Science of "Yet"
There’s a high school in Chicago where students didn’t get a failing grade. If they didn't pass a course, they got a grade of "Not Yet." Think about how that feels. "Fail" says you’re at a dead end. "Not yet" says you’re on a path, you just haven't reached the destination. This is the heart of the growth mindset. It’s the realization that the neurons in your brain actually get stronger and form new connections when you struggle with something difficult.
When you're sitting at your desk feeling like your brain is melting because you can't figure out a problem, that "melting" feeling is actually the sound of you getting smarter. People with a fixed mindset interpret that frustration as "I’m not good at this." People with a growth mindset interpret it as "My brain is growing."
Real World Examples: From Sports to the CEO Suite
- Michael Jordan: He wasn't a prodigy. He was cut from his high school varsity team. He didn't succeed because of "natural" talent; he succeeded because he was the guy who stayed in the gym after everyone else left to practice the shots he missed.
- Lou Gerstner & IBM: When Gerstner took over IBM in the 90s, it was a classic fixed-mindset culture. Everyone was focused on being the smartest guy in the room and protecting their turf. He shifted the culture toward learning and customer needs, saving the company from the brink of death.
- The "Math Person" Myth: Studies show that when girls are told math is a "natural talent," their performance drops compared to boys. When they are taught that math is a muscle you build, the gender gap almost disappears.
Is the Mindset Theory Flawless?
Look, we have to be real here. Psychology has been going through a "replication crisis" lately. Some researchers, like Timothy Bates and Yue Li, have tried to recreate Dweck’s famous studies and didn't always get the same massive results.
Critics argue that mindset might not be as powerful as Dweck claims. They suggest that things like poverty, access to resources, and baseline IQ still play a huge role in success. You can't just "mindset" your way out of a failing school system or a lack of food.
Dweck’s response has usually been that the interventions have to be done right. You can’t just put a poster on the wall and expect grades to jump. It has to be a deep, cultural change in how we talk about mistakes. Even so, it’s worth acknowledging that a growth mindset is a tool, not a magic wand.
How to Actually Change Your Mindset
If you’ve realized you’re living in a fixed-mindset world, you don't need a total personality transplant. It’s about catching the "voice" in your head.

1. Identify the Trigger
We all have a "fixed mindset persona." Maybe yours shows up when you get criticism. Or maybe it’s when you see someone else in your field doing better than you. When you feel that surge of defensiveness or jealousy, name it. "Oh, there’s my fixed mindset trying to protect me."
2. Add the Word "Yet"
It sounds cheesy, but it works. "I don't know how to code" becomes "I don't know how to code yet." It keeps the door open.
3. Stop Praising Results
Start noticing when you praise people—including yourself. Instead of "I’m so proud of that A," try "I’m really impressed by how you stuck with that essay even when the first draft was a mess."
4. Seek Out the "Ugly" Learning
If you’re only doing things you’re already good at, you aren't growing. You're just validating. Go do something where you’re the worst person in the room. Feel the awkwardness. That’s where the actual change happens.
The bottom line is that the brain is much more like a muscle than we used to think. You wouldn't go to the gym, lift a 5lb weight, and say, "I guess I’m just not a strong person." You’d know you have to lift the heavy stuff to get stronger. Your brain is the same way. The struggle isn't a sign that you're failing; it's the only way you know you're actually moving forward.
Your Next Steps:
Pick one thing this week that you’ve been avoiding because you’re "not good at it." Spend 30 minutes on it with the explicit goal of making mistakes. When you mess up, tell yourself, "My neurons are literally forming new connections right now." See if that shifts the frustration even just a little bit.
