Overthinking is often mistaken for intelligence. People assume that if they are thinking a lot about something, they must be being careful or thorough. But overthinking is not depth, it is repetition without resolution.
It happens when the mind is stuck in a loop without a defined endpoint.
The real issue is not thinking too much but thinking without closure. When there is no deadline, no decision boundary, and no commitment step, the brain continues cycling through the same arguments indefinitely.
To fix this, you need to introduce an external structure.
Start with time constraints. Most everyday decisions do not require extended analysis. In fact, longer thinking often reduces decision quality because it increases doubt and introduces new irrelevant variables.
Next, reduce options aggressively. Instead of comparing five or six possibilities, narrow it down to two or three meaningful choices. Anything beyond that is usually noise rather than signal.
Then, most importantly, commit once the decision is made. Commitment is what stops mental reprocessing. Without it, the brain continues to revisit the decision as if it is still unresolved.
A useful concept here is “satisficing,” which describes choosing an option that is good enough rather than optimal, because in real-world environments, optimisation is often impossible or counterproductive:

Overthinking is not a sign of careful thinking. It is a lack of structured closure.
