Notice who you actually like. Your favourite coworker. The neighbour you’re closest to. The person in class you always sat near. The friend who became your best friend.
Now notice the thing they have in common. It isn’t that they’re the finest people available to you. It’s that they’re the ones you saw the most.
That’s uncomfortable, because we like to believe attraction is a verdict on someone’s specialness. A lot of the time it’s something far less romantic, and once you can see it, you get a strange kind of power over your own heart.
familiarity is read as safety
In 1968 the psychologist Robert Zajonc showed people a stream of symbols and faces, some many times, some just once, and asked how much they liked each. The result was almost embarrassingly clean: the more often something appeared, the more people liked it. Nothing about the thing changed. Only how familiar it was.
This is the cognitive bias mere-exposure effect We come to prefer things simply because we’re exposed to them repeatedly. A lot of “chemistry” is really just proximity and familiarity.
the doors experiment
The cleanest proof is an old housing study from MIT in the 1950s. They looked at who became friends in an apartment complex, and the strongest predictor wasn’t shared interests or personality or values.
It was how close their front doors were. People one door apart were dramatically more likely to become friends than people just four doors down. Not better-matched. Just nearer. The proximity did the work we love to credit to chemistry and fate.
which is why the phone doesn’t count
Here’s the catch that matters right now. Mere exposure needs a real, physical encounter. Seeing someone’s posts, watching their stories, being “in touch” online, none of it produces the same effect as sharing air with them.
So the great migration of our social lives onto screens has quietly disabled the most powerful friend-and-love-forming mechanism humans have. We are in contact with more people than ever and near almost none of them, and I think a lot of modern loneliness lives in exactly that gap. Proximity builds trust. Scrolling doesn’t.
and sometimes it isn’t them at all
There’s a last layer, and it’s the most personal one. Sometimes the pull toward a person isn’t really about the person. It’s about who you get to be when you’re near them.
You like how fast you think in their company. You like the version of yourself that shows up in that conversation. And you attribute all of it to them, when a good part of it is coming from you. This is worth checking, gently, especially if you keep falling for people who are slightly out of reach. (It’s close cousins with intellectual attraction, where the fascination can be a mirror.)
None of this makes your feelings fake. It makes them legible. If attraction is mostly proximity, familiarity, and the self you get to be, then you’re not at the mercy of it. You can choose your rooms, choose who you’re near, and let the oldest machinery in your brain start working for you instead of by accident.
