Have you ever pressed the closed button in an elevator? Or, have you played with an office thermostat because you were either too hot or too cold? Or, did you press the “walk” button on the crosswalk this morning? Did it work? If so, you’ve been deceived. Indeed, Placebo Button is a Countermeasure to Some Problems.
Since we are psychological creatures, the solution to some of our problems might not actually solve our problems – we just think they do. Such is the case with placebo buttons.
What is a Placebo Button?
A Placebo Button is a device that when activated – turned on, turned off, pressed, depressed – actually does nothing. We just think it does. In effect, if we are cold, the countermeasure is to turn up the heat. When we actually do turn up the heat on the office thermostat, nothing happens but we feel warmer. It turns out that those within the HVAC industry understand this practice well. By some accounts, over 50% of office thermostats actually do not work and over 90% of elevator buttons to close the elevator actually do not work either.
Indeed, those within the HVAC industry have exclaimed:
[HVAC Technician] always said that “thermal comfort is 90 percent mental and 10 percent physical.”
And, the placebo effect is producing some very real results. Consider this reduction in service calls 1:
The people in the area felt’ better that they could now control the temp in their area. This cut down the number of service calls by over 75 percent, wrote David Trimble of Ft. Collins, Colorado.
And more,
The dummy stat did nothing except to give the occupants the impression that they had control of the HVAC system, Langless wrote, and the psychological effect of having control of their work environment. Our service calls disappeared, and to my knowledge, that system is still set up and working as it has since 1987.
In a way, placebo buttons give the illusion of control and they also pacify our desire to quickly jump to solutions. To our dismay, these buttons we’ve been pressing all along don’t actually do anything. But, we think they have and we’re complaining less about the problem.

I agree, many buttons and controllers are simply placebos. However, I was surprised to find that the “close door” button on the elevator at the Hampton Inn actually closed the door. I stay at a particular Hampton Inn often and have experimented with pushing the button in the elevator. Regardless of when I push it, the door closes about 1 second after I push it.

When I compare my relative warmth when skiing and when walking around Denver, I see your point…. It’s always colder on the lift than on the slopes, for example! Thanks for the explanation!

Pete, the same is true of many “cross walk” buttons in the UK (I guess you mean pelican crossings)
Unfortunately there is little placebo effect to be gained from the snooze button on my alarm clock
