It is only natural- as you are waiting to cross the street, you push the crosswalk button expecting to cross the street sooner. However buttons such as these are actually just placebo buttons, giving you a false sense of control.
As for crosswalks buttons, there was a time when pedestrians needed to press the button to get the signal to walk. However in 2004, the New York Times reported that more than 2,500 or 3,250 cross walk buttons had been deactivated with the emergence of computer controlled traffic signals. As cities have become more congested, a signal button for pedestrians to walk appears, regardless, because the system assumes that there are always pedestrians looking to cross. For these crosswalk buttons to work, they would actually have to change the functioning of the traffic light systems, allowing the pedestrians to walk at the time when the button is pressed. Especially in highly populated cities, it is just impossible for the cycle to be manipulated by one pedestrian. This means that pushing that crosswalk button really has no effect on when you will get to walk.
Another button that remains to be useless are elevator “close door” buttons. This is because when the Americans With Disabilities Act was passed in 1990, it was mandated that elevators stay open long enough for someone with a physical disability. This is obviously a righteous necessity, allowing someone on crutches or utilizing a wheelchair to make it in the elevator on time. But in this sense, all of the times you have pushed the elevator close buttons have been for nothing.
Although it may seem frustrating that these buttons serve no purpose, pushing them gives us a sense of control. These buttons act as placebos, having no effect but being psychologically fulfilling for the user to push. Yale psychology professor Ellen Langer explains this illusion of control saying “feeling you have control over your world is a desirable state.”
So you may ask what is the point of having all of these buttons that no longer serve a purpose? The answer is simple, it would be too costly to remove all of these buttons. It just isn’t worth the hassle, money, and construction time of removing an elevator close door or crosswalk button.
Next time you go to push an elevator “close door” or a crosswalk button think twice about if what you are doing is just a squandered action.
