Placebo Effect

A strange phenomenon found in medicine is the placebo effect, where a patient’s symptoms improve after being given a completely inert substance (like a sugar pill) under the guise of a medication. The placebo effect is not only limited to pills, but any procedure that is intended for a therapeutic purpose (but does not have any actual therapeutic value). It is believed that the placebo effect is a strong component in many forms of alternative medicine such as homeopathy and faith healing. The placebo effect has been proven to be effective in improving or even curing the symptoms of some diseases such as allergies, asthma, headaches, abdominal pains and even severe illnesses such as heart attacks and cancer. Placebos are particularly effective for psychological symptoms.

There has been much research to determine how the placebo effect works. The leading theories so far are that placebos act to relieve anxiety and condition the patient into a more positive mindset, reducing stress and boosting the body’s natural healing process. This would also explain why placebos are effective in pain relief as perceived pain is amplified by negative emotions. Cognitive dissonance may also play a role, where the patient’s mind believes that since it is receiving treatment, it must be getting “better”, producing a beneficial psychosomatic reaction. Essentially, fooling the mind to believe and expect that it will get better makes the patient actually feel better.

Research into the placebo effect has also revealed some bizarre characteristics of the effect. For example, it has been found that the placebo effect is stronger if there are more pills, the pill is larger, branded or generally looks fancier. Even colour plays a role, with blue pills acting better as depressants (“downers”) and red pills acting better as stimulants (“uppers”). Telling a patient that a placebo will have a certain effect boosts that effect. Human factors such as the doctor’s credibility and confidence or the patient’s expectations and culture are known to drastically change the efficacy of a placebo. What is weirder is that studies have shown that telling a patient that they are being prescribed a placebo will not affect its efficacy, as long as they are told that “it could help them”.

The placebo effect is a great example of how much influence our mind, beliefs and expectations have on our health and our lives. The more positive thoughts and beliefs we have, the healthier we become. The more negative we are, the less effective treatments become. In fact, the same pill that gives people the placebo effect can be used to increase pain and symptoms if it is described in a certain way. This is known as the nocebo effect – the opposite of the placebo effect.

The Three Christs Of Ypsilanti

On July 1, 1959, a social psychologist named Milton Rokeach began an experiment in Ypsilanti State Hospital in Michigan to explore the nature of delusions. He gathered three paranoid schizophrenics who each believed they were Jesus Christ and put them in one room. Technically, there can only be one Jesus Christ. So how did the three schizophrenics respond to each other’s claims that they were Jesus?

The experiment ran for two years, with the three patients meeting regularly with Rokeach (under the guise that it was a support group). The initial meetings were far from peaceful. One “Christ” would yell out that the other two were fakes, while another would decry that he would not worship the other Christ as he was the real Jesus. The third reasoned that there cannot be more than one Jesus, and that he was the Good Lord. The arguments escalated to the point of physical violence in many cases. No one would budge and accept that the other person could be Jesus, as they themselves were Jesus. It was the ultimate paradox and cognitive dissonance, as there can be only one Jesus.

Rokeach hoped that the patients would soon see the error of their delusions. He even went as far as sending each of them fake letters from the patient’s “wife” and “the hospital boss” to see if they would alter their routine as the letter advised. But instead of breaking down and accepting that they were deluded, the three patients each found an explanation to resolve the cognitive dissonance.

One patient declared that his fellow patients were actually dead but being controlled by “machines”, thus their arguments were not credible. The other two explained that the other patients were “crazy” people with mental health issues, thus they should not be believed.

This is not a surprising ending to the story, as the definition of a delusion is that it is a “fixed, false belief not amenable to reason”. By definition, a delusion cannot be “reasoned” or broken with logic. Even if you blatantly show the patient proof that their delusion is not real, the patient will not yield. Instead, they will find creative ways to work around the inconvenient truth. Ergo, no matter what evidence you put forward, those three patients would always, in their mind, be the one and only Jesus Christ.

Now let us assume that you met a doppelgänger who states that they are the real “you”, challenging your identity. How would you respond? Challenging one’s identity is the most vicious attack possible, as no person is secure enough with their own identity to be unaffected by the attack. Because people define themselves with a set identity, changing even a small portion of their identity causes extreme confusion and panic. To avoid such emotional turmoil, the brain does everything in its power to protect the identity it believes in. This is why people will respond with fury and anger when their identity is challenged.

People say that “I know myself the best”. But if we construct our identities around flimsy, false foundations, we would still cling to the idea that that is our true identity. If people were to suggest that we are not who we think we are, our brain would defend its identity at all costs. In that case, are our identities delusional? How do we know whether our identity is the real us, or a delusion our brain is clinging to?

Better yet, imagine that everyone around you claimed that you are a duck. Even though you know for sure that you are not a duck, everyone else sees you as a duck and defines you as a duck. An interesting thing about delusions is that the definition includes the phrase: “…and not in keeping with that person’s subculture”. This means that if everyone in your subculture were to say that your belief and your identity were wrong, you could be labelled “delusional”. In that case, are you crazy or is everyone else crazy?

Politics

The following is an excerpt from the Analects by Confucius, titled The Secret of Politics:

Confucius’ disciple Zi-gong asked him: “What is politics?”
Confucius replied: “The key to politics is to make food plentiful(足食), keep enough soldiers(足兵) and earn the people’s trust(民信).”

Zi-gong thought about this, but decided it was too hard to do all three. He asked again: “If you had to give up one, which would you choose?”
Confucius replied: “I would give up the soldiers.”

Zi-gong asked again: “If you had to give up one more thing, which would you choose?”
Confucius thought for a minute and said: “I would give up food. If you believe, you can withstand hunger for a while and withstand the hardships of war, but if you lose trust you will immediately lose everything.”

The character 信 stands for trust, which is believing in another person. Of course there must be trust among the people, but Confucius teaches us that the trust between the people and their leaders is the most important. In fact, with trust and faith you can overcome anything. If you can respect and trust in your leaders, you can endure hunger and at times, even summon the strength to defeat your enemies with your bare hands.

An administration that has lost the hearts of the people will fail.

Brainwashing

The term brainwashing describes the act of converting a person’s deepest thoughts and ideologies. The term originated from the efforts of the Chinese army to convert US soldiers to communism in the Korean War.

The Chinese first made American prisoners-of-war write essays hailing communism, then gave them some rice, candy or cigarettes as rewards.
The intelligence officers posited that the prisoners would be tormented by the reality of having to act against their ideology (of anti-communism) to receive such petty rewards, and that they would convert their beliefs to escape this. They were right.

A significant number of Americans who were given rewards after writing the essays defected to become communists after the war. This was because they justified their actions, believing that they did not write the essays to get a few candies, but because they truly are communists. Converting them did not require horrific torture or heavy bribery. All the officers needed were some candy, and the powerful psychological phenomenon known as cognitive dissonance to play with a grown man’s mind.

Leon Festinger said: “People are not rational beings, but beings that rationalise themselves”. People easily get caught in the trap of self-justification, and distort reality and even their own memories to accommodate it.

Power Of Thought

The power of thought is extremely potent. Beliefs can drive people to extreme actions, or let those who lost everything pick up and carry on. Not only does this apply to religion, but all beliefs have a powerful effect on us.

The most easily observed effect is that the mind has over the body. In the 1950s, an accident occurred where a sailor was trapped in a refrigerated container on a cargo ship. There was plenty of food, but he knew he had no hope when his fingers and toes begun to go numb, and as his body started go stiff. Instead, he decided to record the pain and suffering of freezing to death on the wall using a piece of metal. By the time the ship arrived at the port, he had already frozen to death. However, the container was not refrigerated as it was not being used – the sailor had killed himself with the power of thought.
This shows how thought affects the way we perceive the world, which forms the basis of the placebo effect. If you give a patient sugar pills and tell them it is medicine, it is common to see an improvement in their health. This is due to the body’s amazing ability to repair itself, yet the brain believes the drugs helped it recover.

Thoughts and beliefs affect society as well.
Private property, the monetary system, authority and ethics are all products of the human mind. This is called the Tinkerbell Effect, where some things only exist because people believe in them. The name comes from how Tinkerbell from the play Peter Pan is revived with the belief of children.

Furthermore, believing can determine the future. In philosophy, there is something called the Thomas Theorem, which states that “If men define situations as real, they are real in their consequences”. For example, if there is a rumour that a bank will go bankrupt, people will withdraw their money and cause the bank to go bankrupt. 
This theorem explains self-fulfilled prophecies, a type of prediction that causes the events to take place because of the prophecies. Horoscopes and fortune telling are largely based around this effect, where telling a person that “good things will happen” (or bad) will cause the person to think positive (or negatively) and result in them acting in favour of positive results (or negative). 
This strange phenomenon is described very well in the movie “The Matrix”. When Neo visits the Oracle, she tells him “Don’t worry about the vase”. When he says “What vase” and turns around, he knocks over the vase behind him, causing it to fall and shatter. The Oracle then questions whether the vase would have broken if she had not told him about it. A similar case is seen in “Terminator” and “Back To The Future”.

As shown above, thoughts and beliefs contain immense power, and all humans need to do to make a better world is imagine and believe in such a world. However, the problem is that we seem to be unable to utilise this potential.
