Negative thoughts don’t loop because they’re true.
They loop because of how your brain is filtering reality.
Research suggests we have around 60,000 thoughts a day. Around 90% are repeated thoughts — and around 70% are negative. That’s a relentless internal commentary running mostly beneath our awareness, shaping how we feel about ourselves and the world without us even noticing.
The good news: these thoughts aren’t facts. They’re the product of a filtering system that has learned to look for certain kinds of information. And filtering systems, unlike personalities, can be changed.
Why the brain defaults to negative
Our brains process approximately 11 million pieces of information per second. The conscious mind can handle about 40. Everything else gets filtered by the subconscious, which uses past experience, memories and patterns to decide what to pay attention to.
When those past experiences have taught the subconscious to look for threat, rejection, failure or unworthiness — that’s what it finds. Not because those things are everywhere, but because the filter is tuned for them. This is sometimes called a negativity bias, and it’s often deeply connected to the core beliefs formed in early life.
Cognitive distortions — the thinking errors that amplify the noise
Cognitive distortions are habitual patterns of misinterpretation — ways the mind consistently distorts reality in the direction of our fears and insecurities. They feel completely true. They’re not. Here are the most common ones:
All-or-nothing thinking — no middle ground, everything is a success or a failure
Catastrophising — leaping to the worst possible outcome from limited evidence
Mind-reading — assuming you know what others think, usually negatively
Personalisation — taking responsibility for things that aren’t yours to carry
Emotional reasoning — treating feelings as facts (‘I feel like a fraud, therefore I am one’)
Disqualifying the positive — dismissing evidence that contradicts the negative belief
Mental filtering — focusing only on what confirms what you already believe
Should statements — the constant internal rules about how things must be
Most people have two or three that dominate. Women in particular tend toward personalisation, self-blame, and people-pleasing — patterns that are often rooted in early experiences of conditional love or approval.
Why you can’t think your way out of them
The same applies here as with anxiety: emotions overpower logic. By the time you’re caught in a loop of negative thinking, your nervous system has already responded. The body is already tense, the breathing already shallow. The logical mind is trying to catch up with a process that started before it got involved.
This is why journalling, reframing and positive affirmations can feel effortful and temporary. They’re working at the conscious level — trying to override a pattern that lives much deeper.
What to do with this
There are two levels of work here. The first is environmental — becoming more intentional about what you allow in. The media you consume, the people you spend time with, the conversations you have. None of these are the root cause of negative loops, but they can amplify or dampen them significantly.
The second is somatic — building the practice of noticing your body’s responses before the thought spiral takes hold. A body scan, breathing techniques and grounding exercises all help interrupt the loop once it’s started. I’ve written a full guide to somatic tools for anxiety and stress that goes into these in detail.
But the most lasting change comes from addressing the subconscious origin of the pattern. RTT Hypnotherapy goes directly to the beliefs and experiences that have been tuning the filter — and changes them at the source. When the belief updates, the brain’s filtering system updates with it. The thoughts don’t just get managed. They lose their charge.
