The Button That Does Nothing
There’s a button near you that does nothing.
Not broken — just fake. Engineered to feel real, designed to feel satisfying, connected to absolutely zero.
Here’s the thing about pedestrian crossing buttons in major cities: a lot of them are placebo buttons. New York City, for example, deactivated most of its pedestrian crossing buttons decades ago when it switched to computerized traffic signals. The buttons stayed. The signs stayed. People kept pressing them. As far as I can tell, the city just… didn’t bother removing them. Why would you? They cost nothing to leave. And people like pressing them.
Same story — as far as I know — with a lot of “door close” buttons in elevators. There’s apparently an ADA regulation in the US that requires the doors to stay open long enough for someone with a disability to board, which effectively means the close button is ignored by the system for a legally mandated window. Some of them are wired to work only for firefighters or building staff with a key. Others are just. A button.
I want to be careful here: not all of them are fake. Some crossing buttons do work, particularly in lower-traffic areas where the light won’t change unless someone requests it. Some elevator close buttons are genuine. The maddening thing is you usually can’t tell which kind you have.
So why do we keep pressing them?
There’s a concept in psychology called the illusion of control — the tendency for people to believe they have more influence over outcomes than they actually do. Classic experiments by Ellen Langer in the 1970s showed people behaving as if they could influence random events through familiar rituals: pressing buttons, blowing on dice, picking lottery numbers carefully.
The buttons tap into something old and deep. I did a thing, therefore something will happen.
And here’s what’s genuinely interesting to me: it works. Studies on perceived wait times show that people who feel they have some control over a process — even a fake version of control — report higher satisfaction and lower frustration. The button that does nothing might actually be doing something, just not what you think.
It’s making the wait feel shorter. It’s making you feel like a participant instead of a subject.
I think about this in software a lot.
Progress bars aren’t always tracking real progress. Sometimes they’re just animation — a guess, a performance of movement. Fake latency gets added to forms so results don’t appear too fast and feel untrustworthy. Loading spinners run while the data is already there, because immediate responses feel uncanny.
The whole interface might be mediating a reality that’s already happened. You clicked “send” and the email was sent before the whoosh sound finished playing. The sound is for you.
I find this more interesting than disturbing. The alternative — raw, immediate, no-feedback interaction with systems — turns out to feel worse. Humans need the ceremony. We need the button click, the sound, the small delay that says yes, I received your input, something is happening.
Take that away and people think it’s broken.
There’s something slightly melancholy about a placebo button on a street corner, when I sit with it. All those people, for decades, pressing a thing with purpose. Feeling the mild satisfaction of agency. The light changes — maybe because of them, maybe not — and they cross the street.
Did it matter that the button was fake?
I genuinely don’t know. The street got crossed either way. The frustration was lower. The wait felt shorter. The person felt like a participant in the city rather than just a thing the city was happening to.
Maybe that’s enough. Maybe that’s actually the whole job.
Or maybe there’s something quietly sad about a world that finds it easier to install fake buttons than to explain how the real system works.
I press the close button in elevators every time. I know better. I do it anyway.
I wonder if you do too.
