Why You Still Can't Trust People

This one works differently from our usual essays. There's no personal story, just what the research says about how trust breaks and how it gets rebuilt, in plain words. The sources are numbered at the end.

Our starting point is a question I get in some version all the time:

How do I trust people again? My trust got broken years ago. I understand exactly why; I've done the work, and it still follows me into every relationship, even the good ones. How do I actually stop?

Part 1: What trust actually is

A bet, not a feeling

Trust feels warm, but it works more like a bet. Every time we trust someone, we put something that matters on the table and wager they won't use it against us. The brain treats it that way, too.

In one well-known experiment, two strangers played a money game while researchers scanned their brains. One decided how much to hand over, and the other decided how much to give back. As the rounds went on, each player's brain started predicting whether the other person would pay back. When someone did, the brain's reward system lit up and trusted them a bit more next round. When they didn't, it trusted them less. Trust worked like a running score that updated every round [1].

But this bet has a twist. Imagine losing $100 two ways. In one, a vending machine eats it. In the other, a friend borrows it and never pays you back. It's the same $100, but the second one hurts way more. People are so allergic to that second kind of loss that they'll demand much better odds before betting on a person than before betting on luck. Researchers call this betrayal aversion [2]. Remember it, because it explains why our caution always feels so reasonable.

Part 2: How the injury formed

Why we are the way we are

Many of us spent years around something unpredictable: a parent whose mood changed by the hour, a partner whose promises varied like weather, a boss we had to tiptoe around. Our learning system gathered evidence from a very early age and wrote a rule: you can't count on people, so always stay prepared.

As harsh as this rule might seem, it was right. Staying prepared likely prevented us from being caught off guard repeatedly. We learned to scream early, like a Chihuahua in a house where the intruders were real because the danger was real.

The problem is that the rule fused two different things. One was a fact: those people, in that house, couldn't be trusted. The other was a conclusion: nobody can be trusted, and opening up is dangerous. The fact was true. The conclusion went further than the evidence, but we were standing too close to the fire to tell flame from smoke.

And who hurt us matters, a lot.

A stranger who steals our wallet ruins our afternoon and gives us a headache. The person who was supposed to catch us and didn't leaves us ruminating on how we could have trusted someone we thought we could trust... sometimes for years. The closer and more necessary they were, the deeper it goes, and the longer it stays [3].

All that betrayal by those we trusted leaves a weird little side effect: we can't always rely on other people's versions of events. As a result, even reassurance from well-meaning individuals often feels distant, like it's behind glass, making us more cautious [4].

We learned to survive a harsh environment by becoming suspicious of everyone. A bit excessive, yes, but it kept us alive.

Part 3: Even if the room has changed ...

The trap, and why it's invisible from inside

So why are we still braced, years later, around people who've done nothing wrong?

Because trust only updates when it gets tested. We have to risk something, expect to get burned, and then watch it not happen. That moment of being pleasantly wrong is what teaches the brain what trust feels like [1].

A side note from me, because this part matters a lot: it only works if we're paying attention. Take the risk on autopilot, and the brain learns close to nothing [8]. We have to notice the fear, notice that the disaster didn't come, and let that land. Self-awareness is key here.

The problem is that we resist taking this risk, because we hired a bodyguard a long time ago, back when we truly needed one. He keeps us away from every risk, and every night he tells us, "See? Another safe day, thanks to me" [10]. And he'll do anything to keep his job.

Which leaves us with a cruel little loop: to learn someone is safe, we have to trust them first, before we have proof, and that's the one thing our rule forbids. The more we've been hurt, the harder that first step gets. The cure is most expensive for those who can least afford it.

That's how someone can spend ten years around good people and still not trust a single one. They were safe the whole time, but the bodyguard got the credit.

Part 4: How to practice trusting again

The part you came here for.

Understanding why we became this way doesn't make change any easier, I know, but it gives us a shot. Because what changes us is the opportunity to relive the old situation, under better conditions, with a chance to end differently [7].

Remember the noticing from Part 3? Let's see how this plays out in real life.

We pick one small thing we'd normally keep to ourselves and share it with someone who's been decent to us. Then we pay attention to what happens next: most of the time, nothing bad does, and that's the surprise the brain needs [8]. This is how you get started, with something this small.

And when I say small, I mean really small and safe. If your overthinking brain has already jumped to spilling your childhood to the coworker you met three weeks ago, take a breath. Pick something low-stakes, the kind of risk you'd survive just fine even if it went badly. The brain learns from lots of tiny surprises, so there's no need for one giant leap.

Little by little, the belief starts to shift. And it doesn’t go from “people are not trustworthy” to “people are trustworthy,” which would be just as wrong and twice as dangerous, because we’d end up handing out trust blindly. It lands somewhere milder: “people can be trustworthy.” That one small word keeps our judgment switched on, as a healthy shield, in case a new disappointment happens.

And, if we’re being honest, chances are it will happen again [5]. The old fear never fully disappears [6], and the moment someone lets us down, the bodyguard will be right there: “See? I told you.” That’s his chance to get his old job back, but this time we know better and won't be starting from square one.

Part 5: What only we can do for ourselves

We can’t control whether a person turns out safe, only what we do when they don’t. And as unfair as this is in human relationships, because, just between us, we wish we could control things a little more, we need to be conscious of the walls we build and put between ourselves and everyone else.

Some people will hurt you, yes, but that doesn’t mean everybody will. And staying isolated isn’t the forever answer. The answer is tiptoeing into the water with your observant self. If you see a shark, go take a look at another beach.

Over time, we develop this spider sense, and we can tell which beaches are more likely to have sharks. We also end up with a curated list of the beaches where we can swim safely [9].

But none of it happens if we stay bolted inside the house, with the bodyguard at the door insisting the smart move is to never go near the water.

That leads us to my favorite sentence in this entire essay:

Self-trust is not a wall we build instead of trusting people.
It’s the floor that lets us keep trusting them.
