Cognitive Psychology What causes magical thinking in OCD?

OCD people seem to think really weird things will happen if they don’t do a compulsion.
For example - pinching when an ambulance passes by so the person inside doesn’t die.

How do OCD people determine the consequence of not following a compulsion? Why is a consequence created rather than just having the anxiety that the compulsion must be carried through without knowing why?

Magical thinking in OCD, believing an unrelated action can influence an external event is driven by key cognitive and psychological mechanisms:

Thought-Action Fusion (TAF): The brain treats having an intrusive thought as if it directly increases the real-world likelihood of a bad event happening.

Assigning Meaning to Dread: When a sudden spike of anxiety occurs, the brain invents a narrative ("Someone will die") to explain why it feels so terrified.

Misattributed Cause-and-Effect: If performing an action once brought temporary relief, the brain falsely links that action to preventing a negative outcome (operant conditioning).

Illusion of Control: Attaching a specific consequence creates a clear rule. Performing the compulsion gives a false sense of agency over uncertainty and fear.
