Why does the loop keep running?
Not what it's running about — but why it keeps going, why it won't stop at a natural conclusion, why it has such staying power?
The answer is not what you might expect. It's not the content of the thoughts. It's what you believe about the act of thinking them.
Adrian Wells' metacognitive model: it's not the thoughts themselves but beliefs ABOUT thinking that sustain loops
Positive metacognitions: 'worrying keeps me safe / prepared / in control' — these maintain the habit
Negative metacognitions: 'I can't control my thinking' — these increase anxiety and fuel avoidance
Questioning the beliefs about worry is more powerful than questioning the worries themselves
Adrian Wells, a clinical psychologist at the University of Manchester, developed Metacognitive Therapy — an approach that has produced some of the most impressive results for rumination and worry in clinical research. His central insight: it is not the thoughts themselves that sustain anxiety and loops — it is the beliefs you hold about your thinking.
He identified two categories of problematic metacognitions:
Positive metacognitions — beliefs that worry and rumination are helpful, necessary, or self-protective: - "If I worry about this enough, I can prevent it from happening" - "Going over it again helps me understand it better" - "Worrying shows I care" - "If I'm prepared for the worst, I won't be caught off guard"
These beliefs make perfect sense — and they are largely false. Worry does not prevent bad outcomes. Going over a problem in a loop does not produce new solutions; it produces the same solutions repeatedly. Being prepared for the worst mainly means experiencing the worst before it happens.
Negative metacognitions — beliefs that your thinking is uncontrollable or dangerous: - "I can't stop once I start" - "This worrying will make me ill" - "If I'm thinking this, I must be a bad person" - "My thoughts are out of control"
These beliefs create anxiety about the anxiety, which adds a second layer of suffering on top of the original worry.
Wells' therapy — MCT — targets these beliefs directly, and its results for rumination and generalised anxiety are remarkable: 70–80% recovery rates in randomised controlled trials, often faster than CBT.

Ask yourself honestly: why do I keep returning to this loop?
Complete these sentences:
"I believe that going over this worry repeatedly is helpful because ___."
"I believe that if I stopped worrying about this, ___."
Now gently examine: is this actually true?
Has worrying about this thing ever once prevented it from happening? Has the loop ever produced a solution that one clear pass of thinking didn't produce?
Write what you actually believe — and what a more accurate version might be.
The loop is maintained by your beliefs about it. Questioning those beliefs is the most powerful intervention available. Tomorrow: cognitive defusion — the art of watching thoughts without becoming them.
