You've Been Firing Friends Since the Middle Ages — You Just Called It 'Unfollowing'

You've Been Firing Friends Since the Middle Ages — You Just Called It 'Unfollowing'

Somewhere in the last year, you quietly stopped responding to someone. Maybe you muted their stories. Maybe you let a text sit for three weeks and then just... didn't. You probably told yourself it wasn't personal. That you were just busy. That the friendship had run its course.

You were right, actually. It wasn't personal. It was economic.

And the merchant guilds of 14th-century Florence would have completely understood.

The Social Budget Problem Is Not New

Here's the uncomfortable psychological truth that no productivity guru will put on a motivational poster: human beings have a hard ceiling on how many meaningful relationships they can maintain at once. British anthropologist Robin Dunbar put a number on it in the 1990s — roughly 150 stable social connections, with an inner circle of maybe five. His research drew on primate behavior and human community sizes across cultures and centuries.

But Dunbar didn't invent the constraint. He just named it.

For most of human history, that ceiling was enforced by geography. You lived in a village. You knew the same 80 people your whole life. The pruning happened automatically — people died, moved away, or drifted into the background without you having to make any conscious decision at all.

Then trade happened. And suddenly, for the first time, humans had to manage relationships with people they'd never meet in person, across distances that made casual contact impossible. The medieval merchant didn't just need to track inventory. He needed to track people — who was reliable, who had stopped being useful, who was worth a costly letter-writing campaign and who wasn't.

The social audit became a professional survival skill.

How a Florentine Merchant Managed His Contact List

The merchant account books that survived the medieval period are fascinating documents, and not just for economic historians. Read between the lines and you find an elaborate system of relationship tracking that would look familiar to anyone who's ever organized their phone contacts into tiers.

Francesco Datini, the 14th-century Italian merchant whose correspondence archive is one of the most complete records of medieval commercial life, wrote thousands of letters — but he also stopped writing thousands of letters. His biographers note that his network was in constant flux: allies elevated, partners demoted, old contacts quietly allowed to lapse when the cost of maintaining them outweighed the benefit.

This wasn't cruelty. It was arithmetic. A letter in 1380 cost time, money, and a courier. Maintaining a relationship with someone in Bruges when your business had shifted to Barcelona was a resource drain you couldn't afford. The friendship didn't end dramatically. It just... stopped being renewed.

Sound familiar?

The Visibility Problem

What's genuinely new about the modern version isn't the behavior — it's the receipts.

When Datini stopped writing to someone, that person probably noticed eventually, but there was no timestamp. No read receipt. No follower count that visibly ticked down by one. The social audit happened in the background, invisible and deniable.

Instagram changed that. So did LinkedIn, Twitter, and every other platform that turned relationship maintenance into a quantified, public act. Now when you unfollow someone, there's a record. When you leave a group chat, everyone sees the notification. The cold calculation that humans have always made got a user interface — and suddenly it felt brutal in a way it never had before.

But the calculation itself? Identical to what a Roman patron was doing when he stopped inviting a client to dinner. Identical to what a medieval guild master did when he quietly stopped sponsoring an apprentice's advancement. The tools changed. The psychology didn't move an inch.

Why Ghosting Feels Worse Than It Is (And Why We Do It Anyway)

Psychologists who study social rejection consistently find that being ignored activates the same neural pathways as physical pain. That's not metaphorical — the anterior cingulate cortex, which processes physical hurt, lights up in brain scans when people experience social exclusion. Getting ghosted genuinely hurts in a measurable, biological way.

And yet ghosting — or its historical equivalents — has been a dominant social strategy for millennia. Why?

Because the alternative is worse. Explicit rejection is socially costly for both parties. It requires confrontation, justification, and often damages broader social networks when the news spreads. Allowing a relationship to quietly expire through non-renewal is lower-cost, lower-drama, and — critically — preserves the fiction that the door is still open.

Roman social etiquette had elaborate conventions for exactly this. The gradual withdrawal of invitations. The increasingly brief acknowledgment at public events. Everyone understood the language. Nobody had to say anything out loud.

We didn't invent ghosting. We just gave it a name and then felt bad about doing something humans have always done.

The Attention Economy Made the Math Harder

There's one genuine way the modern situation differs from what a medieval merchant faced, and it matters.

Datini's social network had natural friction. Distance, cost, and time automatically limited how many relationships he could even attempt to maintain. The constraint was external.

Yours isn't. Your phone contains the theoretical ability to maintain contact with every person you've ever met, at near-zero marginal cost per message. The ceiling that geography used to enforce is gone. Which means the pruning that used to happen passively now has to happen actively — and consciously.

That's why the modern friendship audit feels more fraught than it probably should. You're not doing anything new. You're just doing it with full awareness, in an environment that was specifically designed to make every social connection feel equally accessible and therefore equally obligatory.

The merchant who let a Bruges correspondence lapse didn't feel guilty. He couldn't realistically maintain it anyway. You can maintain everything — in theory. So when you don't, it feels like a choice. Because it is.

The Ledger Closes the Same Way It Always Did

Here's what five thousand years of human social behavior suggests: the pruning is necessary, it's normal, and fighting it doesn't make you more loyal — it just makes you more exhausted.

Every society that left records shows the same pattern. Inner circles of five to ten people who receive the bulk of emotional investment. A second tier of useful, pleasant acquaintances maintained at lower cost. An outer ring of contacts kept warm just enough to be reactivated if circumstances change.

Your contact list isn't a moral document. It's a ledger. And you've been balancing it — whether you admitted it or not — your entire life.

The medieval merchant would recognize your problem instantly. He'd probably also tell you to stop feeling bad about it and get back to work.

Though he might phrase that last part differently.
