 Pressing your elevator’s door close button incessantly might make you look like a bad neighbor, and chances are, it’s not even helping you get to your destination any faster. 
  
 An earth-shattering New York Times piece examines a number of things in our world that appear to have a purpose but actually mean nothing, including that familiar button. 
  
 Karen W. Penafiel, executive director of National Elevator Industry Inc., explained to the Times that the door close function is now largely a thing of the past, thanks to legislation passed in the ‘90s. 
  
 Once the Americans With Disabilities Act was passed, it was required that “elevator doors remain open long enough for anyone who uses crutches, a cane or wheelchair to get on board,” she said. The Times adds that “firefighters and maintenance workers who have the proper keys or codes” can still activate the function. 
  
 The ruling makes complete sense, but we can’t help but feel a little bit lied to by our beloved elevators. Head to the New York Times to see more and excuse us while we resist the urge to keep pushing. ||||| But as The New York Times reported in 2004, the city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals. More than 2,500 of the 3,250 walk buttons that were in place at the time existed as mechanical placebos. Today there are 120 working signals, the city said. 
  
 About 500 were removed during major construction projects. But it was estimated that it would cost $1 million to dismantle the nonfunctioning mechanisms, so city officials decided to keep them in place. 
  
 Most of the buttons were scattered throughout the city, mainly outside of Manhattan. They were relics of the 1970s, before computers began choreographing traffic signal patterns on major arteries. 
  
 ABC News reported in 2010 that it found only one functioning crosswalk button in a survey of signals in Austin, Tex.; Gainesville, Fla.; and Syracuse. 
  
 Office thermostats 
  
 The same problem that confronts couples at home — one person’s perception that a room is too cold is another’s that it is too warm — faces office workers as well. 
  
 Depending on where you work, you might find the thermostat in a plastic case under lock and key, but if you’re lucky you might have control over one. 
  
 Well, you might think you have control. 
  
 The Air Conditioning, Heating and Refrigeration News reported in 2003 that it asked readers in an informal online survey whether they had ever installed “dummy thermostats.” Of 70 who responded, 51 said they had. |||||

This. Changes. Everything. A feature in the New York Times notes that door-close buttons in elevators don't actually do anything—and haven't for decades. Functioning door-close buttons went out with the introduction in 1990 of the Americans With Disabilities Act, which requires doors to stay open for people in wheelchairs, using crutches, and so forth, explains National Elevator Industry executive director Karen Penafiel. Repair people and firefighters still have keys or codes that make the door-close buttons work, but for us regular schmoes the button is a mere tease, Quartz reports. "We can't help but feel a little bit lied to by our beloved elevators," laments a blog at the Huffington Post. But just because door-close buttons don't actually close doors doesn't mean they're completely useless. The Times reports they act kind of like a psychological placebo. "Perceived control is very important," Harvard psychology professor Ellen Langer says. "It diminishes stress and promotes well being." John Kounios, another psychology professor, describes the door-close button as "mildly therapeutic" since the door does eventually close, providing the button-pusher with a reward. Kounios says he doesn't think people will ever stop pressing the door-close button—or any of the other buttons in the world. "I've got nothing else to do while waiting, so why not press the button on the off chance that this one will work?" he says. (Amtrak comically flubbed a response to a trapped elevator rider.)
