Have you ever wondered why two people can face the exact same setback—a job loss, a breakup, or a harsh critique—and walk away with two completely different internal realities? One person sees a challenge and a chance to pivot; the other sees a final verdict on their worth as a human being.
In our previous exploration of Perceptual Biases, we looked at the “filters” our brain uses to interpret daily life. We discussed how the mind is a “Meaning-Making Machine” that jumps to conclusions to avoid uncertainty. But today, we need to go deeper. If Perceptual Biases are the filters on the lens, Core Beliefs are the lens itself.
They are the unseen foundation upon which your entire psychological house is built. From a Cognitive Behavioral Therapy (CBT) perspective, understanding your core beliefs isn’t just “self-help”—it is the key to decoding why you feel the way you do and, more importantly, how to finally find joy.
Core beliefs are the absolute truths we hold about ourselves, other people, and the world. They are usually formed in childhood and reinforced through decades of experience. Because they are so deeply embedded, we rarely think to question them. We don’t say, “I have a belief that I am inadequate”; we simply feel, “I am inadequate.”
Think of your mind as a sophisticated computer. Your Automatic Thoughts (the “I’m going to fail this”) are the software notifications popping up on your screen. Your Perceptual Biases are the operating system. But your Core Beliefs? They are the hardware. They dictate what the software is even capable of doing.
Most core beliefs fall into two primary categories: Lovability/Worth and Safety/Competence. When these foundations are shaky, anxiety becomes a permanent resident in your nervous system.
If your core belief is “I am fundamentally flawed” or “If people really knew me, they wouldn’t like me,” your brain becomes hyper-vigilant in relationships. Every silences is a sign of abandonment. every critique is a confirmation of your brokenness. You don’t just feel sad; you feel endangered.
If your core belief is “The world is a dangerous place” or “I am incompetent,” your brain stays in a state of high-alert. You perceive every challenge as a threat you aren’t equipped to handle. This is the breeding ground for chronic anxiety and “High-Functioning Burnout.” You aren’t just working hard; you are working to outrun a core belief that says you aren’t enough to survive on your own.
Joy requires a certain level of vulnerability. It requires the ability to let your guard down and trust that you are safe. However, if your “Unseen Architect” has built a foundation of “I don’t deserve good things,” your brain will actually sabotage moments of joy.
Have you ever had a great day, only to feel a sudden “drop” or a sense of “waiting for the other shoe to fall”? That is your core belief trying to bring your reality back in line with your internal map. To the brain, familiarity feels safer than happiness. If you are used to feeling anxious, joy feels “wrong” or “unearned.” You aren’t experiencing the world as it is; you are experiencing it as your core beliefs allow you to.
Core beliefs use a “Confirmation Bias” to stay alive. Your brain acts like a biased judge: it admits any evidence that supports the belief and throws out any evidence that contradicts it.
This is why “positive thinking” often fails. You can’t spray-paint “I am confident” over a foundation of “I am worthless” and expect it to stick. You have to address the masonry of the foundation itself.
How do we begin to shift these absolute truths? In therapy, we use a process called Socratic Questioning and Behavioral Experiments. Here is how you can start the “demolition” of a painful core belief today:
Look at your recent spikes of anxiety. Use the “Downward Arrow” technique.
Imagine your core belief is a defendant in a courtroom. You are the prosecutor. You must find evidence against this belief that is 100% factual. Not “I feel like I’m okay,” but “I have maintained three friendships for over five years,” or “I have successfully completed my job duties for 12 months.”
If your belief is “I am incompetent,” your brain will try to keep you from trying new things to “protect” you from the “truth.” Challenge it. Do something small where failure is possible, and observe the outcome. Did the world end? Are you still standing? You are teaching your nervous system that the “rules” it created 20 years ago no longer apply.
Shifting a core belief is not about lying to yourself or pretending life is perfect. It is about accuracy. It is about realizing that the rules you wrote when you were a child—rules designed to keep you safe in a specific environment—may be the very things keeping you trapped today.
When you begin to repair the foundation, your “Meaning-Making Machine” starts to generate different stories. A late text is just a busy friend. A mistake at work is just a data point. Joy stops feeling like a fluke and starts feeling like your natural state.
You are not the architect of your past, but you are the foreman of your future. By looking at the “Hidden Foundation,” you create the space for a life built on reality, resilience, and a deep, unshakable sense of worth.
