Why You're Drawn to Cold People

In the 1990s, Wolfram Schultz recorded the activity of dopamine neurons in monkeys. The first drop of juice triggered a powerful burst. But once juice began arriving after a cue, the burst for the juice itself almost disappeared - it shifted to the cue. A reward you can predict stops being an event.

Dopamine here works not as a pleasure hormone, but as a marker of prediction error: this turned out better than I thought. Steady warmth is predicted perfectly, the error is zero, and the system stays quiet. Someone who replies in a minute one time and disappears for 3 days the next keeps that error high all the time.

That explains the strange feeling: with someone reliable, you feel calm but there's no spark; with someone unpredictable, there's chemistry. The spark isn't a measure of depth. It's the amplitude between what you expected and what arrived.

You can tell by where your attention goes. You think about someone available. About someone unavailable, you think about what their silence means and reread their last message.

3 days of silence - and 2 words carry more weight than a daily "good morning" from someone who's there. Not because they're warmer. Because they weren't in the forecast, and by then you'd had time to imagine the worst.

It's usually explained like this: you're drawn to cold people, so you don't value yourself, or it's about childhood. Sometimes that's true. But the mechanism works without it too: in Skinner's experiments, pigeons pecked a key most persistently not when food came every time, but when it came every other time. Intermittent reinforcement hooks everyone - it's a property of the schedule, not a personal flaw, and your history affects how long you stay in it, not whether it hooks you at all.

The difference matters. If it's about being broken, you'd need to fix yourself for years. If it's about the schedule, it's enough to see the schedule. The pull won't disappear overnight, but it will stop reading like a sign of fate.

A caveat: the shift in dopamine response from reward to cue is reliably replicated, but applying laboratory patterns to real relationships is an explanatory model, not a measured fact.

But even as a guess, it's more useful than a diagnosis: looking at the schedule of warmth is easier than looking at a list of everything broken in you.
