At the school where I teach, teachers stand in the hallway during passing periods. Admin tells us it's because "our presence has power." The idea is simple: an authority figure in the hall changes how students walk through it. No intervention required. The possibility of being caught is enough.
Still, we don't watch them every minute of the day because, as teachers, as authority figures, we have to be aware of the effect that our presence has.
I know what happens when I stand behind a student at their computer. They close the tab. They stop typing. The student who was halfway through a Wikipedia rabbit hole, following something that might have actually taught them something, clicks away.
The one who was writing, badly, freely, in the way that first drafts require, stops.
What I interrupted (by just standing there) wasn't misbehavior. It was the condition that makes real work possible. A little privacy. Not secrecy. Not concealment. Just space.
Space to think without performing, to write a bad sentence without someone grading it before it becomes a good one, to follow a link without explaining why. That space is not a luxury. It is a requirement. You cannot think carefully and perform carefulness at the same time. The self-consciousness that surveillance produces is not neutral. It is a tax on cognition, and it gets paid whether or not you have anything to hide.
This is what teachers learn, if they're paying attention. You can monitor a classroom into compliance, you can also monitor it into silence.
The "nothing to hide" argument sounds reassuring until you sit with it for a moment. What it's actually asking is that you demonstrate your innocence continuously, to every platform, on every search, in every click. It reframes privacy as a privilege extended to the blameless rather than a condition that belongs to everyone. It assumes that the only reason to want space is to fill it with something wrong.
But that's not why you close your office door. It's not why you pull the blinds. You don't consider either of those actions a confession. The expectation of privacy in those moments and spaces isn't a statement about guilt. It's a precondition for doing certain kinds of work, having certain kinds of thoughts, and being a certain kind of person, yourself.
The argument also assumes that surveillance is passive. That it simply watches what you would have done anyway and flags the bad parts. But that's not how it works, and it's not how people work.
The research on this is not new. It goes back at least to Jeremy Bentham's prison experiment, the prison design where inmates could be observed at any moment without knowing when they were being watched, and the insight that the uncertainty itself was the mechanism of control. You don't need to watch everyone all the time. You just need everyone to know they might be watched. The behavior change follows automatically.
You just need everyone to know they might be watched.
More recent research has made this concrete in ways Bentham couldn't. A 2016 study published in the Journal of Communication found that awareness of NSA surveillance caused measurable self-censorship in Google searches on sensitive topics. People didn't stop searching because they were doing something wrong. They stopped because the possibility of observation made certain searches feel risky in a way that had nothing to do with their actual content. The surveillance didn't catch bad behavior. It prevented behavior entirely, including behavior that was entirely legal.
This is what Elizabeth Stoycheff, who led that research, called the spiral of silence effect applied to online behavior. People conform to what they perceive as acceptable when they believe they are being watched. The watch doesn't have to be real. The belief is enough.
I think about this when students ask me why privacy matters if they have nothing to hide. It's a fair question and I take it seriously because the answer isn't obvious. Privacy doesn't feel like something you have until you notice it missing. It's like asking someone why they need sleep. The case for it is most visible in its absence.
Here's what I tell them.
The version of you that exists under observation is not the same as the version of you that exists without it. That's not a moral failing. It's a feature of being human. We are social creatures. When the environment says you are being evaluated, you begin evaluating yourself through the same lens. You become your own worse critic and start worrying about "what my FBI agent thinks."
That self-monitoring is useful in some contexts. It is corrosive in others. The contexts where it is most corrosive are exactly the ones that matter most: learning something difficult, forming an opinion, writing something true, making a decision under uncertainty, being wrong in a way that eventually leads to being right.
Surveillance doesn't wait for you to do something wrong. It changes what you're willing to do before that question ever comes up.
What ever happened to innocent until proven guilty?
Online surveillance operates on the same principle.
When you search for something sensitive, visit a site repeatedly, or linger on a page longer than average, that behavior is being recorded and interpreted. Not by a person, but by systems that make inferences about who you are based on what you do. Those assumptions follow you. They shape what you're shown, what you're charged, what opportunities appear in front of you, and. increasingly, what decisions are made about you without your input.
The data that feeds those systems doesn't come from moments where you've done something wrong. It comes from ordinary online behavior. The search you ran at 2am. The article you read three times. The extension you installed to make your browser a little easier to use. None of those feel like disclosures. But they are being treated as such, aggregated, inferred against, and in some cases sold to parties you've never interacted with and cannot identify.
When I close the door to my classroom it isn't (always) because I'm taking a nap or watching Netflix. It's because particular kinds of work require a particular kind of atmosphere, and that atmosphere depends on the fact that I'm not being monitored by a student, coworker, or administrator.
The closed door isn't about what's behind it. It's about what becomes possible when you know it's yours to close.
That's true in a bedroom. It's true in an office. It's true in a browser.
You don't have to be guilty to lose something under surveillance. You just have to be human. And the version of yourself you lose isn't the worst version; it's often the most honest one.
You don't have to be guilty to lose something under surveillance. You just have to be human.
