The placebo effect is the idea is that simply believing that a medical treatment will work is enough to make that treatment effective. A patient who thinks he is taking an aspirin for a headache is likely to get the same relief if he swallows a sugar pill meant to look like a painkiller. The effect is powerful enough that control groups in studies of treatment effectiveness receive a dummy treatment to control for it. Now, some new evidence suggests that other there is other things in life that will work the same way. Buttons and devices around us may cause a change in perception, where one does not exist.
One such device is the “close door” bottom on elevators. Passengers push it a lot, but the doors are on a timer. The button in most elevators only works with a special key, though most riders never realize it. No matter how many times the button is pressed, the door eventually closes anyway. Another device is an HD or High definition label on a television. The label is used so often these days, there is a wide definition of what High Definition. Dutch scientists discovered that simply hearing that a television is hi def is enough to convince viewers the picture is better. In a 2009 study, researchers showed 60 people an identical video clip on identical televisions. They told half the participants the clip would be in high-definition, and even attached an extra thick cable to the back of the set. Researchers told a control group to expect a normal DVD image.
Afterwards the group that was told they were watching a better picture thought the picture was better on what they were told was high-definition even though it was exactly the same as a normal DVD image. Researchers say the study is a good reminder that an assurance that something is “high quality” does not only make a person more likely to buy a product, it may also subtly influence their enjoyment of it.
