Here’s something about thoughts that will either blow your mind or annoy you — possibly both: that relentless inner voice narrating your life, judging your decisions, and reminding you of every cringeworthy thing you’ve ever said at a party?
That’s not you. That’s just your brain doing what brains do. The problem is that most people have confused the radio for the DJ.
You have somewhere in the range of 6,000 thoughts per day. A significant chunk of them are negative, repetitive, and completely unhelpful. If you are treating every single one as a reliable report on your character, your worth, or your future — we need to talk.
Thoughts: The Problem With Living Inside Your Head
Psychologists have a term for what happens when you can’t separate yourself from your thoughts: cognitive fusion. It’s the state of being so entangled with your mental content that a thought like “I’m not good enough” stops being a passing mental event and becomes a fact about who you are.
The research on this is clear — and a little alarming. A 2024 study on cognitive defusion found that cognitive fusion significantly increases psychological inflexibility and emotional distress, and that people who are fused with their negative thoughts experience greater anxiety, depression, and a reduced quality of life. Not exactly the recipe for a good time.
The antidote — backed by decades of research in Acceptance and Commitment Therapy (ACT) — is something called cognitive defusion: the practice of creating distance between yourself and your thoughts so you can observe them rather than be controlled by them. Think of it as moving from being the storm to watching the storm.
Research comparing cognitive defusion to thought distraction strategies found that the defusion approach significantly reduced both the emotional discomfort and the believability of negative self-referential thoughts — even among participants with elevated depressive symptoms. In other words, the goal isn’t to fight your thoughts or shove them down. It’s to stop taking them quite so seriously.
You Are Not a Fixed Story
Now here’s where it gets interesting — and where Carol Dweck enters the chat.
Dweck’s foundational research on fixed versus growth mindsets isn’t just relevant to learning; it cuts right to the heart of how people relate to their inner lives. A fixed mindset operates on the assumption that your qualities — intelligence, personality, worth — are set in stone. When you fuse with your thoughts from a fixed mindset position, a thought like “I failed at that” becomes evidence of a permanent, unchangeable truth: “I am a failure.”
This is where cognitive fusion and fixed mindset become a particularly nasty tag team. A fixed mindset amplifies the emotional impact of negative thoughts. Research shows that people with fixed mindsets are more likely to use emotional suppression — pushing uncomfortable feelings down rather than processing them — which tends to make everything worse, not better.
The growth mindset flips this entirely. Rather than treating a difficult thought as a verdict, it treats it as information. Anxiety about a presentation? That’s your nervous system signalling that this matters to you. A thought that you’re struggling? That might mean you’re growing. Research published in the British Journal of Educational Psychology has extended mindset theory beyond intelligence into the domain of thoughts, feelings, and social-emotional skills — finding that people who believe their emotional responses are malleable develop far more adaptive strategies for managing them.
The growth mindset doesn’t deny hard thoughts. It refuses to let them write the ending.
Where Emotional Intelligence Comes In
Emotional intelligence — the ability to perceive, understand, and manage your own emotions — is essentially the operating system for everything we’ve discussed so far. Without it, cognitive defusion is just a technique you read about and immediately forgot.
Self-awareness — the ability to tune into your emotional states and understand how they affect your thoughts, behaviours, and relationships — is the first and most foundational component of emotional intelligence. It is what allows you to notice a thought arising before you’ve already been swept away by it.
Here’s the sequence: awareness precedes choice. If you can’t notice you’re having the thought “everyone in that meeting thinks I’m incompetent,” you can’t choose what to do with it. You’ll just be it. Self-awareness gives you the half-second gap between trigger and reaction that changes everything.
Research on emotional intelligence consistently shows that self-regulation — the ability to monitor and manage emotional responses — follows directly from self-awareness. People who develop both are better equipped to handle setbacks, navigate conflict, and make decisions that aren’t driven entirely by whatever panicked story their brain is currently generating.
The good news, for those of you with a fixed mindset about emotional intelligence: it is learnable. The malleability of EQ is widely acknowledged in the literature, meaning this isn’t something you either have or you don’t. You can build it. Deliberately.
The Observer Who Watches the Thoughts
ACT’s most powerful concept — and the one most people overlook — is what researchers call “self-as-context.” This is the idea that you are not the content of your mind; you are the awareness that notices the content. You are the observer, not the observed.
A 2024 study examining psychological flexibility in clinical settings found that people who increased their capacity to observe thoughts without fusing with them showed improved quality of life, reduced anxiety and depression, and better overall functioning — effects that remained stable three months after treatment ended.
This isn’t meditation woo. This is measurable, replicable science. The observer position is what allows you to say: “There’s that thought again. Interesting. What do I actually want to do here?”
Research on negative self-referential thoughts shows that simply prefacing a thought with “I am having the thought that…” significantly reduces both the emotional impact and the believability of the thought. Not because the thought is gone — it isn’t — but because you’ve created just enough distance to remember that the thought is something you’re having, not something you are.
“I am worthless” hits very differently from “I am having the thought that I am worthless.” The content is the same. The relationship to the content has completely changed.
The Fixed Mindset Trap (How Thoughts Keeps You Stuck)
Let’s be direct about something. A fixed mindset isn’t just a learning style. It’s an identity trap. When you operate from fixed mindset assumptions, your thoughts about yourself feel like facts because you’ve already decided the story is finished.
Research on fixed mindset describes it as a “self-reinforcing framework of perceptions, beliefs, reactions, and goals.” In practice, this means that a fixed mindset thought gets recycled back into the system as evidence, which generates more fixed mindset thoughts, which generate more evidence. It’s a closed loop, and it’s exhausting.
People with fixed mindsets are more likely to experience procrastination, self-handicapping, and negative mental health outcomes including depression. Not because they’re less capable — but because they’ve handed authority over their identity to their thoughts, and their thoughts are doing a terrible job.
The growth mindset, by contrast, introduces what Dweck calls a “not yet” — the recognition that a difficult thought or experience is part of a process, not a conclusion. You didn’t fail; you haven’t succeeded yet. You’re not incapable; you haven’t figured this out yet. This reframe isn’t toxic positivity. It’s a fundamentally different — and evidence-backed — relationship with the stories your mind tells.
Your Simple Action Plan
You don’t need a therapist and a ten-year meditation practice to start changing your relationship with your thoughts. You need a few reliable moves, practised consistently.
Step 1: Name the thought, not yourself. When a harsh thought arrives, say — out loud if possible — “I’m having the thought that…” before finishing the sentence. Do this every time. It sounds small. The research says it isn’t.
Step 2: Get curious about your emotional state. Before reacting, pause and name what you’re feeling. Anxious? Frustrated? Embarrassed? Self-awareness is the entry point to self-regulation — you can’t manage what you haven’t noticed.
Step 3: Ask the growth mindset question. When a thought feels like a verdict, ask: “Is this a fact, or is this my brain pattern-matching to old information?” Then ask: “What would I do here if I didn’t believe this thought?” The answer to that second question is almost always more useful than anything the original thought was offering.
Step 4: Take values-based action, not thought-based reaction. ACT research consistently shows that the most psychologically flexible people ask: “Does following this thought move me toward or away from what I actually value?” Your values don’t change based on a bad mood. Your thoughts do. Lead with the values.
Step 5: Repeat. Regularly. Without expecting perfection. Defusion isn’t a one-time fix. It’s a practice — which means some days you’ll nail it, and some days you’ll be completely fused with a catastrophic thought spiral before you even realise what happened. That’s fine. Notice it, name it, and start again. That is the growth mindset in action.
Let’s Tame Those Thoughts
You’ve been running your life like a courtroom where every thought gets to testify about who you are. It’s time to appoint a judge — and that judge is you, not your mental weather.
The research is there. The tools are simple. The only thing standing between you and a fundamentally different relationship with your inner life is the decision to stop treating your thoughts as autobiography.
Start today. Pick one thought that’s been following you around lately — the one that feels most true and most damaging. Write it down. Now write: “I am having the thought that…” in front of it. Read it back. Notice what shifts.
That’s your starting point. Not the thought. You — the one noticing it.
