Anybody that has ever held any interest in looking for objective truth in the world will likely have stumbled across the concepts of rationality, reason, science and logic at some point during their perusal of pertinent proofs. Ever since the postmodern era was unceremoniously ushered into western culture, bringing with it all of the counterintuitive paradigms that facilitate abominations such as homeopathy and psychic mediumship, we seem to have all fallen prey to the immensely bad idea that what is true for me could be a completely different state of affairs to what is true for the next individual.
This idea, of course, seems immensely appealing since it allows us to fill our respective boots with the warming notion that we alone can know a truth that nobody else can know. It makes us special from within our own perception. Homeopathy does this immensely well. It makes claims about the real world that simply will not be tested and verified by any worthy method, and then goes on to add the clause of, if you don’t believe then it won’t work.
This clearly creates a problem, because the real world just does not work in this way. If all truths are simply inside our heads then there is nothing out there at all. The whole concept of universal truth is reduced to introspection and nothing of what is outside of our own head can ever be known. However, we know that there is something beyond our own perspective because we experience and interact with it every day of our lives. We have theories that can model the universe, from the very big to the very small, with staggering accuracy and absolutely repeatable real-world practical application. We’ve put men on the moon, invented satellites that measure the background radiation from the big bang and can show us ‘baby pictures’ of our universe. We don’t claim that these theories are entirely complete, but humanity is working on it.
If something works then it works, and should be able to be repeatedly tested and verified as a truth. If it doesn’t hold up to a convergence of processes that attempt to both prove and disprove the validity of the claim, then it is likely amongst thousands, perhaps millions, of phenomena that are simply anomalies that can be explained by minute mathematical probability. Evidence is the key. We call this way of thinking science.
Science tries immensely hard to place it’s perspective outside of the mind and perceptual framework of the observer. The scientific mind knows some of the many psychological biases that impede our judgment and can take steps to attempt to eliminate them from any experiment that you care to mention. Here I have compiled some of these biases and attempted to sketch an outline of the way that they affect our perspective of what is truly out there in the real world. (Note: they affect everybody. There is nobody that doesn’t experience these every day of their lives. It’s part of being human.) :

The Confirmation Bias
The confirmation bias is the psychological process which filters out the misses and only notices the hits in support of what we wish to believe. This is the human trait that most psychic mediums who work on a face-to-face basis prey on when they employ the ‘cold reading’ technique. They make use of a set of sweeping, generalised statements, designed to probe at the sitter’s (the poor person who has usually paid good money to experience this violation is called a ‘sitter’) personal situation. Usually, the sitter gives enough information away, either by physically indicating or actually answering, for the medium/cold reader to continue making general statements and if the ‘hits’ outweigh the ‘misses’ the sitter goes away feeling that they have just been given an incredibly specific reading. This example actually goes one step further, since the sitter will often ignore misses anyway and simply cling to what fits and ‘feels right’ for the sake of not feeling stupid.
Whenever proper testing has been carried out on such proprietors, they tend to get results of roughly (mostly below) 50% which is a slightly lower result than you can achieve for guessing.
The Blind Spot bias
A Princeton University study has revealed that test subjects can recognise the cognitive biases of other subjects but fail to see the same biases in themselves.
The Self Serving Bias
Studies have also shown that people have a tendency to perceive themselves in a more positive light than the light in which others view them. In other words, we all tend to believe we are the main character of our own ‘life movie’, and why should we not? After all, we evolved with survival as a primary concern. At a primordial level, surely if we view ourselves as the central roll then we can focus on making the most of our own life.
Studies to support this include national surveys which reveal that 60% of American high school seniors would place themselves in the top 10% in, “ability to get along with others.”

B.F Skinner’s Habitual Pigeon Experiment
It turns out, as American psychologist B.F Skinner revealed in his infamous experiments, these cognitive biases are not local to homo sapiens. He, quite roughly I should imagine, threw some pigeons into cages and after shaking them profusely set about beginning the experiment… I am obviously lying. B.F Skinner was never, to my knowledge, charged for animal cruelty. He did however monitor the ritualistic habits of such animals. He would place the little blighter into a bird box and have a food releasing mechanism, wired to a timing device, thrust pellets of food unto them at random intervals. He observed that they would carry out rituals, such as tapping their heads on the floor, in an attempt to make the food appear faster. If their ritual seemed to them to be effective no more than a few times, they would adopt it as a behaviour and continue to do it regardless of the fact it had no bearing on anything other than possibly giving them a headache.
This phenomenon is symbolically representative of human behaviour such as prayer. Usually, if a person’s prayer appears to be answered, even in completely coincidental terms, they will repeat the process for the rest of their life. They completely disregard the reality of the matter in favour of what seems to be the truth for them subjectively.
Consider for a moment that a person of religious faith would pray to feel better after two days of suffering from the common cold virus. She has been taking paracetamol regularly for the past day, but nothing seems to be effective in making her feel better. On the third day, after the prayer, she wakes up and feels much more healthy. She completely disregards, or remains ignorant of, the fact that a cold virus runs it’s course over a three day span. In all likelihood the antibodies in her immune system have done their natural job and neutralised the virus. Besides, there is no medical cure for the common cold, so paracetamol would only serve to lessen her neuralgia symptoms. She would mistakenly ascribe the increase in her mood and health status to the prayer, usually without thinking about the reality of the scenario, because it is simpler than considering the truth.
The Bandwagon/Cromo Effect
This will likely be a well recognised cognitive phenomena. The notion is simple. A belief, claim or idea spreads more quickly if there are more people that have already invested in it. For example, if there is a group of three friends and two of them become interested in a particular musical artist, the third is likely to become interested in it too. In turn, each of them will likely pass it on to their respective friends who will do the same, ad infinitum. This allows fads, trends and cult thinking to form quickly. However, if ideas form under the influence of the aforementioned bias, we can easily see how bad ideas can spread into mainstream culture. This is how we have arrived at this age of bad thinking in the first place, so quite a literal sense bad thinking can self perpetuate.
Placebo Effect
The placebo effect is immensely interesting and involved. I could never hope to do it justice with a tiny outline in a blog that no one will ever read and so I will keep it short. The placebo effect proves that the grimy subject of pain is indeed just that: subjective. During some operations, surgeons discovered that they could operate with lower, or in some cases no, anesthetic if the patient ‘believed’ they were under the influence of such a drug. More recently placebo pills (usually just a combination of sugars) have been shown to reduce pain in test subjects if they believe it to be some form of medicine. However, as a rule of thumb this only has efficacy in pain related ailments, so don’t expect that eating sugar is going to regrow your broken arm, or cure your viral infection. That’s just a cuckoo idea.
Since we humans are generally looking out for our best interests, I would imagine most of you will be wanting to gain something from this lengthy and likely exhausting lecture. (Yes, a lecture) So what can you selfish, idle miscreants expect to take from all of this wisdom that I have kindly enforced upon your supple minds? I suppose the main point would be never to invest in an idea or belief system, such as new age paradigms or mystical frameworks, that somebody else subscribes to without investigating it for yourself first. In the same vein, never invest in it just because ‘it feels right’ to do so. We have seen how ‘right’ something can feel even though it holds no real-world application, validity from evidence or any repeatable substance thanks to cognitive bias. Is that so much to ask? Literally just asking some questions about these beliefs before granting them room inside your, I am sure, well organised filing cabinet of a mind.
The next time your mystical friend tells you she has some wonderful energy crystals (believe me, these people do exist) that will accelerate the growth of your petunia bush (take the euphemism as you will) simply ask her if she has ever considered trying to grow a separate pot of the same flower in the same conditions, but without use of the crystals. This is merely healthy curiosity. It doesn’t even borderline the dreaded notion of skepticism that so many people are ready to leap away from at the sign of the first venom-tipped pincer. In likewise fashion, if anyone has ever tried to force echinacea upon your vulnerable and influenza ridden form, then take heed to this wonderful factoid. Echinacea has recently been proven no more effective than a placebo. That’s a sugar pill to you and I.
Additionally, never ever believe that something that has real-world application (i.e. medicine) can work for you and you alone. Neither is it a good idea that it will work if you simply believe it. That, my wonderful little bosom-chum, is just silly-talk. You have to consume a little opiate for that.
