It is a flattering story: you overthink because you are unusually intelligent, seeing angles other people miss. It is also mostly a myth, and believing it can quietly keep you stuck, because if overthinking is a gift, why would you ever put it down?
Where the idea comes from
There are scattered studies suggesting that in people who are already anxious, worry correlates with certain kinds of verbal intelligence. Those findings are real but narrow, easy to over-read, and often repeated online with far more confidence than the underlying evidence supports. We went looking for a clean, strong link between overthinking and general intelligence and did not find one. What the psychology literature describes much more consistently is the downside.
What the evidence more reliably shows
Rumination, the backward-facing form of overthinking, is described in a 2015 study in the Proceedings of the National Academy of Sciences as a maladaptive pattern of repetitive, self-focused thought and a known risk factor for depression. That is not a description of a superpower. It is a description of a habit that tends to lower mood and impair clear thinking. On the forward-facing side, the National Institute of Mental Health notes that anxiety turns into a disorder when it does not go away, is felt across many situations, and gets worse over time. Again, not a marker of brilliance, but a pattern that causes distress.
Intelligence and overthinking are not the same axis
Plenty of very sharp people barely overthink at all, and plenty of people who would never call themselves intellectuals lie awake replaying a text. Overthinking is better understood as a threat-sensitive, certainty-hungry habit of mind than as a byproduct of raw intelligence. Smart people can absolutely get caught in it, but the getting caught is not the smartness. It is the loop.
If anything, real intelligence includes knowing when thinking is done. The wisest people are usually not the ones who think the most. They are the ones who can reach a good-enough answer and stop, which is a skill overthinkers are specifically working to build.
Why the myth is worth dropping
Holding onto overthinking as proof of intelligence has a cost. It reframes a painful habit as an identity, and identities are hard to change. If the 2am spiral is just who you are as a deep thinker, there is nothing to work on. But if it is a learned pattern, you can learn a different one. That is a much more hopeful place to stand.
Real people tend to describe overthinking as exhausting rather than impressive. In personal essays collected by The Mighty, contributors write about the way an overactive, worried mind wears them down through an ordinary day, not about the clever insights it hands them. That texture is worth trusting more than the flattering version.
What the myth gets slightly right
To be fair, there is a grain of truth buried in the cliche. Overthinkers often are conscientious, detail-oriented, and quick to see how things could go wrong. Those traits are genuinely useful in the right amount. The problem is not the trait. It is the trait with no off switch. Vigilance that helps you catch a real error at work becomes a liability when it turns the same scanning on a friendly text or a decision that does not matter. So the goal is not to become careless or shallow. It is to keep the useful part, the care and the thoroughness, while learning to call off the search once it has stopped producing anything.
Framed that way, quieting overthinking is not a downgrade in intelligence. It is an upgrade in judgment: the judgment to know when more thinking will help and when it has become pure cost. That is a genuinely smart thing to learn, and it has nothing to do with how the myth flatters you.
A kinder, truer frame
You are not too smart to be calm. You have a mind that leans toward threat and certainty, which is common and changeable. Dropping the intelligence myth does not mean thinking less of yourself. It means giving yourself something you can actually work with. If you want the practical version of quieting the noise without pretending it is a gift, we walk through it in The Overthinker's Manual, and it pairs well with understanding what overthinking actually is in the first place.
