The elevator “close door” button often works as a purely psychological comfort rather than a functional control. Modern elevators are programmed to keep doors open for a legally required minimum time, so pressing the button usually has no effect. Yet people continue to press it because it creates the reassuring illusion that they can speed things up. This small action reduces impatience and gives riders a sense of agency, even though nothing mechanical changes. In this way, the button mostly serves as a placebo for our need to feel in control.
