OCD: Did I Lock the Door? (Checking for the 11th Time)
A person with OCD checks whether they locked the front door, knows they locked it, and still cannot stop going back to check again because the uncertainty is unbearable.
OCD and Intrusive Thoughts
The terrifying thoughts that mean nothing about who you are but feel like everything about who you might become.
Intrusive thoughts are unwanted, distressing thoughts, images, or urges that pop into your mind without invitation. Here is the part most people do not know: virtually everyone has them. Research by Dr. Adam Radomsky and colleagues found that over 90 percent of the general population experiences intrusive thoughts -- including thoughts about harm, contamination, sexuality, and morality that they find repulsive. The difference between a passing intrusive thought and OCD is not the content of the thought but the meaning your brain assigns to it. In OCD, the brain's error detection system -- the anterior cingulate cortex -- gets stuck, sending a constant signal that something is wrong. An intrusive thought that a non-OCD brain would dismiss in seconds gets flagged as meaningful, dangerous, and requiring action. This leads to compulsions -- mental or behavioral rituals designed to neutralize the thought or reduce the anxiety it causes. Checking, reassurance-seeking, mental reviewing, and avoidance are all attempts to gain certainty that the thought does not mean what you fear. But compulsions are a trap: they provide temporary relief that strengthens the cycle, teaching your brain that the thought was indeed dangerous and must be managed. Exposure and Response Prevention (ERP), the gold standard treatment for OCD, works by helping you sit with the discomfort of the thought without performing the compulsion, gradually teaching your brain that the thought is noise, not signal. Understanding that intrusive thoughts are a universal human experience -- not evidence of your character -- is profoundly liberating for anyone trapped in the OCD cycle.
Key Takeaway
The way through OCD is not finding certainty -- it is learning to tolerate uncertainty without performing the ritual.
A Better Approach
A stick figure has a disturbing intrusive thought and labels it: 'That is OCD. It is noise, not signal.'
The stick figure resisting the urge to check, reassure, or mentally review, sitting with the discomfort instead
The stick figure letting the anxious feeling peak and then slowly subside on its own, without a compulsion to bring it down
The stick figure going about their day with the thought still faintly present but no longer in control, labeled 'noise'
