The groups that vaccines left behind
It goes further than sugar pills. There are all manners of fake treatments, even placebo surgery, and the more dramatic the 'treatment,' the better it works.
A lot of how it works is also based on who the 'medicine' is administered by. For example, a robot that pumps morphine into patients at undisclosed times needs twice as much for it to have the same effect as someone who physically sees a nurse administer it by injection.
A BMJ review found that fake surgeries led to improvements 75% of the time.
It’s also been found that placebo treatments are more effective if the patient is hooked up to a machine when it’s administered.
Similarly, if patients are treated with a placebo in a hospital rather than a small private clinic, the results are more effective.
Did you know that the placebo effect isn’t just effective with humans? Canines being treated for epilepsy can also benefit from placebo treatment.
For example, placebo injections are, in many cases, understood to be more effective than pills.
The truth is that psychologists aren’t 100% sure as to why it works. For a long time, the scientific community believed that it resulted from some unknown result of the mind's power.
However, it’s suggested that it’s possibly just because their owners interact differently with them when they know they’re undergoing treatment.
However, it’s been proven that when we take placebo pills, our brain releases endorphins. Endorphins kill the pain.
Placebo medicines can also have a physiological effect on our blood pressure and heart rate.
Findings that upended our understanding of the placebo effect were that people can still benefit from the placebo even after being aware that it’s a placebo!
It’s a similar phenomenon to Russian physiologist Igor Pavlov’s experiments where he conditioned dogs to produce saliva by ringing a bell just before he fed them. Eventually, their mouths drooled with saliva upon the noise of the bell, with no accompanying food to see or smell.
Another less studied area in this field is what has been coined as the "nocebo effect." Essentially, it’s the same thing, but the patients’ anticipation of the medicine having adverse side effects makes them more likely to experience them.
A systematic review found that placebo effectively treats physical ailments like pain, nausea, and asthma.
As previously mentioned, it’s not just about the pills themselves. It’s about the environment and everything else associated with them, like the physician’s demeanor. With this said, it can be deduced that certain doctors administering a placebo medicine will see better results than other doctors.
Warmth and emotional care produce results in treatment. When an acupuncturist asked more questions and was more sympathetic with IBS patients in an experiment, the treatment was more effective.
The placebo effect also works through confirmation bias. This occurs because the patient anticipates the placebo medicine will make them better. In expecting to feel better, the patient pays closer attention to the signs that suggest they are “feeling better.” They may also overlook the signs that they feel the same or worse.
There are considerable limits to what placebo treatment can achieve. For example, there is no way of producing cancer-killing chemicals with a placebo.
The effects of placebo are not just bound to medicine. For example, there have been cases where cyclists who were asked to train until exhaustion would cycle longer if the clocks were tampered with to make them run slow.
Blue placebo pills work better as sedatives than pink ones, and branded ones are more effective than ones with no label.
You can see more activity in the periaqueductal gray matter of the brain (the part responsible for pain management) of a patient with an MRI machine when they’re receiving placebo treatment.
The color and branding of the placebo pills affect how well they perform in treating a patient’s symptoms.
It works for creativity too. If two groups are told to perform a creative task, and one group is told to first smell an odor that makes them more creative, the group told to smell the odor will perform better.
When subjects taking part in a sleep experiment were told that they had more REM sleep than they did, they performed better in language and arithmetic tests.
The same review also found them effective in treating certain issues related to the brain, such as phobias.
Placebo treatments work better for people who are more optimistic and friendly, especially for analgesic treatments.
When hotel staff were told that their work counts as exercise, they saw physical benefits in weight, body mass index, body fat, waist-to-hip ratio, and blood pressure.

A broken electric kettle won’t boil water, and a car with no engine won’t drive, and, yet, fake medicine can sometimes work? It's complex, but the answer is that, in certain cases, yes it can.
For example, a person suffering from depression can be prescribed a sugar pill, thinking it’s an antidepressant, and their symptoms decrease. The same goes for many different illnesses and conditions. Of course, this is putting things rather simply.
But is this as far as it goes? Absolutely not. How the placebo effect works is astounding. To learn all about it, click through this gallery.
