Someone keeps surfacing in your thoughts — an ex, a drifted friend, a near-stranger from one memorable conversation. Rather than twin flames or cosmic signals, psychologists have spent decades identifying the precise cognitive and emotional mechanisms behind this experience. Their findings are both more grounded and more revealing than any spiritual explanation.
In brief
- —They’re probably thinking about you too, research shows
- —Unfinished emotional business keeps the brain looping
- —Trying to forget someone often makes it worse
The ‘thought gap’: why you assume you’re the only one still replaying it
The most common assumption after an intense or unresolved interaction is that the other person has moved on entirely. Research by social psychologists Gus Cooney and Erica Boothby, published in the Journal of Experimental Psychology, tested that assumption directly. Across 8 studies involving more than 2,100 participants, people were asked how much they had been thinking about a recent conversation partner — and how much they believed that person had been thinking about them.
