Seems like someone has rediscovered the: Placebo Button is a push-button or other control that appears to have functionality but has no physical effect when pressed. Such buttons can appear to work, by lighting up or otherwise reacting, which rewards the user by giving them an illusion of control. They are commonly placed in situations where it would have once been useful to have such a button but the system now operates automatically, such as a manual thermostat in a temperature-regulated office. Were the control removed entirely, some users would feel frustrated at the awareness they were not in control. Examples include: * Office thermostats * Walk buttons at pedestrian crossings * London Underground train door buttons * Elevator door close buttons * FCC do not call lists https://en.wikipedia.org/wiki/Placebo_button https://en.wikipedia.org/wiki/Placebo_button
