The Placebo Effect Not Just On Drugs 824

          Specifically, if the race is polling such that the outcome is not in doubt (either for or against your candidate) then your vote becomes meaningless in deciding the outcome. At that point VOTE YOUR CONSCIENCE, (e.g. if you want Libertarian ideals, vote L)

    Well yes and no. It is true that most of them have no effect in normal operation, but when the elevator is in service mode (i.e. apartment move mode), then doors stay open until you press the close button.

    In my sister's apartment, the close button has a effect. The normal door open time is about 40 seconds, and it will close the instant you press the close button (i.e. after 5 seconds). In the office building that I'm in (mid 60s construction), the close button has no effect unless the elevator is in service mode).

      the close door buttons DO work in our building (FWIW we have Otis) but there's a trick which I've experimentally confirmed: something has to trip the sensor between the inner & outer doors to make it think someone has gotten on or off. I can consistently (100x out of 100 tries) replicate the following behavior: if elevator stops on floor w/nobody waiting I simply waive my hand in the gap, press the close button & the doors immediately close/elevator continues - press the button w/o something having tripped the sensor & it just sits there till its normal timeout period.

    I read an article in the Washington Post ~20 years ago about people waiting in lines. A hotel was constantly receiving complaints about the speed of their elevators. They kept tweaking the elevators, but the complaints continued to roll in (despite the quantifiable improvements). Rather than continuing to pursue the problem with technology, they turned to psychology and installed mirrors in the elevator lobby. Seems that if people have something interesting to look at (to them at least), the time passes more quickly and they do not notice that the elevators are slow. After they made this final change, the complaints stopped. I think about this every time I see a mirror in an elevator lobby.

    "Placebo effect" implies a perceived improvement. I think it's obvious by the number of times people push elevator close door or street "walk" buttons, or fiddle with office thermostats, there is no perceived improvement.

  • by ugen ( 93902 ) on Monday November 08, 2010 @01:17PM (#34163504)

    "Placebo" refers to situation where a patient does not know that the medication is inactive.

    I am not sure about everyone, but I happen to know that most "close" buttons on elevators and most street crossing buttons to activate a pedestrian traffic lights do not work (the former by design, they are there for fire control mode, the latter mainly because they are broken :) ).
    However, I still continue to use them and the reason is very simple:
    1. They still work occasionally (as was the case just last week in a hotel elevator, where doors would close immediately by using close button, and stay open for extended periods of time without it, tested many times). It's a "nice surprise" when it works - and nothing is lost when it does not work.

    2. They may be required occasionally. I know of a quite a few intersections where pedestrian traffic light won't turn green without the use of a button. It's not worth wasting a few traffic light cycles to find out whether the button is or is not needed. It's easier to just press it - if it works, great, if not - again nothing lost.

    So, to conclude, this situation is nothing like placebo.

    Well, perhaps except for thermostats, but I haven't worked in the office in years - and when I did, never bothered with these things.

      Agreed.

      Also - I don't know about you, but when I press a "close doors" or a "use crosswalk" button and press it, and nothing happens, I tend to press it again. If there was a placebo effect in play, why would I bother pressing it again? The placebo effect suggests that I would be happy with the outcome, rather than stabbing relentlessly away at a soulless machine, like a rat trying to get a food pellet, muttering and cursing the infernal, non functional button and the soul sucking society it seems to embody, when all I want to do is get downstairs and across the street to a bar so I can drown my sorrows in a few glasses of gin and try to muster the courage to talk to that girl who is always there even though I know she's probably damaged goods and wouldn't give me the time of day besides...

    Ah, one of the first positive things that I noticed when I moved overseas was that the "door close" buttons on elevators actually worked. You push them, the door closes. It's that sort of literal-mindedness when a culture apes another culture without knowing why it's doing so. The "how" but not the "why". They didn't know that door close buttons were placebos put in place to lie about giving control. Instead, they connected them up to the control circuits, and when you press the button, by God, the elevator doors close. You can even close the doors directly after they open, ignoring the pleas of people running to get in. Heh, that was another education as well, seeing as I had previously thought that holding elevator doors open for random strangers was something that 'everybody did' - turns out, it's just our culture that does it.

    The elevator close button not doing anything is certainly true most places in the U.S. It isn't worth pushing the button. Go somewhere like Hong Kong, though, and when you hit the door close button the doors close right now. If someone is halfway through the door when you hit it, too bad - they get chopped in half. I love it.

    Walk buttons are different. I can see not having them hooked up at busy intersections, especially at intersections where there are always (or nearly always) pedestrians waiting to cross. Where I live, the buttons absolutely work - the walk signal doesn't illuminate and the signal timings are different if you don't push the button. It is all about maximizing the flow of vehicular traffic while protecting pedestrians. Interesting that they leave the buttons there even when they don't do anything, but I seriously doubt there are many (if any) places where walk buttons were installed purely for the placebo effect.

    Also - you call that an article? Worst. Submission. Ever.

    All these examples seem a bit specific or they assume the people affected are all too dumb to realize someone's trying to fool them...

    'In most elevators installed since the early 1990s, the 'close door' button has no effect. Otis Elevator engineers confirmed the fact to the Wall Street Journal in 2003.

    Around here most elevators don't even seem to have a "close" button, they do have an "open" button though. And if you press one of the "go to floor #n" buttons the doors tend to close immediately. As an example, in the building I live in the best way to get the doors to close quickly is to pass through the elevator door and make sure you're clear of the "don't squish the humans" sensor and then hit a floor button, door closes immediately and elevator gets going.

    Similarly, many office thermostats are dummies, designed to give workers the illusion of control. "You just get tired of dealing with them and you screw in a cheap thermostat," said Illinois HVAC specialist Richard Dawson. "Guess what? They quit calling you."

    Duh. Of course people stop calling you, they're sweating their asses off and you show up and say "nothing wrong here" half a dozen times and then you install a thermostat that doesn't work. Most likely they just end up figuring out how to disable the alarm connected to the windows so they can get some relief that way (seriously, I've seen this problem in several workplaces, the building maintenance guys swear up and down that the ventilation system is fine yet one office which isn't even facing the sun most of the day has stuffy air and a constant temperature above 25 C, in the latest case they finally installed a thermostat that did nothing, we just stopped calling them about the issue (the thermostat was clearly not connected to anything)).

    In 2004 the New York Times reported that more than 2,500 of the 3,250 "walk" buttons in New York intersections do nothing. "The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on."'"

    Here in .se the buttons do work. In fact, if you don't press the button the light never turns green. You still have to wait until the lights for the cars are right though (which kind of sucks, it just switches the light for pedestrians from a default "you're not allowed to cross" to "please wait your turn".

    When I was a young-hacker, I worked as a bellman.. It was slack work except when tour busses came in and then it was a scramble to get luggage up to the rooms. It meant multiple trips with a full cart and no passengers... What I couldn't handle was the long rides down to the lobby stopping at 10+ floors to pickup additional passengers... I soon discovered that if I held the 'door close' button while the elevator was descending, it would stop at the floors where people had pushed the 'down' button but the door wouldn't open. The elevator would stop. Hesitate for about 1.5 seconds, and then start moving again. The unfortunate drawback was that outside of the car, the 'down' light would go out and the waiting passengers would have to press it again to call for another elevator. I then learned that I didn't have to hold the door-close button. If I felt the car slow down and managed to press the button before the car came to a full stop, I could trigger the override.

    Eventually, I got a copy of a master key (which I still have) that allowed me to just put the elevator in service mode and didn't have to override anything.

I always assumed there was some kind of associated safety law. What I don't get is why they keep the damn button there; I assume it's cheaper to do so than to remove the button for the US market. I do know for a fact that the button does work overseas. It's why I would try the button when I got back to the States.

    Honestly, I don't know if in this particular case it's a placebo effect so much as Americans being conditioned to believe that anything in a public space is likely busted or not working properly. There seems to be a general state of disrepair in the US that I haven't really encountered in other countries. On the one hand, you've got ham-fisted oafs and outright vandals who are compelled to break everything in sight. And on the other hand, you've got service people who can't be bothered to do their jobs, or management which apparently doesn't take enough pride to pay to get things fixed. But then, if something keeps getting broken, eventually you just give up and leave it be.

Perhaps this is why science is so important to them? Their instincts are poor and thus they need a reliable system of reality reading, not to fall back on or use in conjunction with, but as their primary guide to existence.

    Hm. Interesting.

    You're darn tootin' we notice!!!! They HVAC people stopped getting calls because people got tired of adjusting the thermostat that never worked and calling the HVAC people. While we may sometimes push that "Close Door" button on the elevator, those of us who use an elevator long enough have realized the timing hasn't been effected since "the late '90s". Isn't New York in enough debt without having to install extra push buttons on every corner of the city if the buttons aren't going to do anything?

    And psychologists wonder why Americans are so up tight, their blood pressure skyrocketing, etc... because the darn "conveniences" don't flippin' work! And apparently, they don't work on purpose. And then we get felt up and/or violated when we use the convenience of quickly traveling from one place to another.

How many QA engineers does it take to screw in a lightbulb? 3: 1 to screw it in and 2 to say "I told you so" when it doesn't work.

Working...
