Thought-Action Fusion
Thought-action fusion is the belief that having a thought is morally equivalent to performing the action — that thinking something sinful makes you as guilty as doing it, or that bad thoughts increase the probability of bad events occurring. In Catholic and other religious contexts, this belief is systematically reinforced by teaching that impure thoughts are themselves sinful, turning the normal stream of unwanted mental content into an ongoing source of moral dread. Research on scrupulosity shows that this specific cognitive bias is elevated in high-religiosity populations and predicts OCD severity beyond general religious participation.

The inner script: 'I just had an angry thought about my mother during Mass — I'm a terrible person. I need to confess this before I can receive Communion.' The research says: intrusive thoughts are universal, morally neutral mental events. Treating the thought as equivalent to the action is the distortion — not evidence of moral failure.
