We all carry beliefs about ourselves, others, and the world. Some are helpful: “I can handle hard things” while others sabotage our confidence, relationships, or goals. These are negative beliefs are deep, often unconscious convictions like “I’m not enough,” “I always mess things up,” or “Good things don’t last for me.”
Negative beliefs can shape how we interpret life. They filter our experiences, coloring what we notice and how we feel. Over time, they start to sound like facts rather than old stories, ones we didn’t choose but have been rehearsing for years.
What Are Negative Beliefs?
In Cognitive Behavioral Therapy (CBT), these are known as core beliefs, the deep structures that influence our thoughts, emotions, and behaviors (Beck, 1979). If you’ve ever noticed yourself reacting strongly to feedback or assuming the worst about a neutral comment, that’s a core belief at work. Core beliefs might stem from a range of experiences or environments.
Negative beliefs are malleable. CBT teaches that while we can’t always control our first thought, we can examine and challenge the belief behind it. EMDR suggests that what we once learned to believe might have been adaptive and we can adapt to newer adaptive beliefs that fit the current reality.
Sometimes, what looks like a “personality trait” (“I’m just anxious,” “I’m too sensitive”) is actually a learned belief system. When you start to question those assumptions, change becomes possible.
How Negative Beliefs Lead to Self-Sabotage
Negative beliefs rarely stay in your head, they tend to leak into behavior. When you believe “I don’t deserve good things,” you might unconsciously make that belief come true by self-sabotaging your own progress.
For example: “Because I secretly believe I’ll fail, I delay the very things that would help me succeed.” Or: “If I get too close to someone, they’ll leave so I pull away first.”
Self-sabotage isn’t about laziness or lack of willpower; it’s the behavioral echo of an old belief trying to protect you from pain. Once you start naming the belief beneath it, the behavior begins to make sense and that’s where real change begins.
Rewriting the Story
These unhelpful beliefs don’t have to continue having the same hold on our world. Through therapies like CBT and EMDR we can reclaim our lives and connect to more accurate chosen beliefs that serve us. CBT offers practical, evidence-based tools for reshaping negative beliefs and by repeatedly challenging and disconfirming negative beliefs, you build new, more adaptive ones; beliefs that feel grounded rather than forced. EMDR works a bit differently. It’s often used when negative beliefs stem from trauma or early adverse experiences. EMDR posits that these experiences can get “stuck” in the nervous system, along with the negative self-beliefs they created (Shapiro, 2018). Through guided bilateral stimulation (such as eye movements or tapping), clients reprocess distressing memories so the brain can integrate them more adaptively. A person who once believed “I’m powerless” might, after reprocessing, genuinely feel “I did the best I could and I’m safe now.”
CBT and EMDR often complement each other beautifully: CBT helps you work with beliefs cognitively and behaviorally, while EMDR helps your nervous system feel that the belief has changed. With many of my clients we implement EMDR in session and learn helpful strategies from CBT to apply outside of session.
Beliefs don’t dissolve overnight but you can work with them and loosen their grip. Over time, the groove smooths out and you start responding to life as it is, not as your old stories predicted it would be.
