You know this feeling. An AI recommendation you cannot fully verify. A decision that has to be made before the data is clear. A transition with no clean ending in sight. And something in your body tightens. A low-level discomfort that does not go away until you know how things turn out. You might call it overthinking. Neuroscience has a more precise name for it.

The contract closed. The presentation landed. The promotion came through. And instead of feeling what you expected to feel, you felt something else entirely. A quiet dread. A waiting for the other shoe. A voice that said they are going to figure out you do not actually belong here. Most people call this imposter syndrome. It is not a syndrome. It is your nervous system. And there is a reason it gets louder after wins.
