The Misconception: You take randomness into account when determining cause and effect.
The Truth: You tend to ignore random chance when the results seem meaningful or when you want a random event to have a meaningful cause.
Abraham Lincoln and John F. Kennedy were both presidents of the United States, elected 100 years apart. Both were shot and killed by assassins who were known by three names with 15 letters, John Wilkes Booth and Lee Harvey Oswald, and neither killer would make it to trial.
Spooky, huh? It gets better.
Lincoln had a secretary named Kennedy, and Kennedy had a secretary named Lincoln.
They were both killed on a Friday while sitting next to their wives, Lincoln in the Ford Theater, Kennedy in a Lincoln made by Ford.
Both men were succeeded by a man named Johnson – Andrew for Lincoln and Lyndon for Kennedy. Andrew was born in 1808. Lyndon in 1908.
What are the odds?
In 1898, Morgan Robertson wrote a novel titled “Futility.”
Written 14 years before the Titanic sank, 11 years before construction on the vessel even began, the similarities between the book and the real event are eerie.
The novel describes a giant boat called the Titan which everyone considers unsinkable. It is the largest ever created, and inside it seems like a luxury hotel – just like the as yet unbuilt Titanic.
Titan had only 20 lifeboats, half than it needed should the great ship sink. The Titanic had 24, also half than it needed.
In the book, the Titan hits an iceberg in April 400 miles from Newfoundland. The Titanic, years later, would do the same in the same month in the same place.
The Titan sinks, and more than half of the passengers die, just as with the Titanic. The number of people on board who die in the book and the number in the future accident are nearly identical.
The similarities don’t stop there. The fictional Titan and the real Titanic both had three propellers and two masts. Both had a capacity of 3,000 people. Both hit the iceberg close to midnight.
Did Robertson have a premonition? I mean, what are the odds?
In the 1500s, Nostradamus wrote:
Bêtes farouches de faim fleuves tranner
Plus part du champ encore Hister sera, En caige de fer le grand sera treisner, Quand rien enfant de Germain observa.
This is often translated to:
Beasts wild with hunger will cross the rivers, The greater part of the battle will be against Hister. He will cause great men to be dragged in a cage of iron, When the son of Germany obeys no law.
That’s rather creepy, considering this seems to describe a guy with a tiny mustache born about 400 years later. Here is another prophecy:
Out of the deepest part of the west of Europe, From poor people a young child shall be born, Who with his tongue shall seduce many people, His fame shall increase in the Eastern Kingdom.
Wow. Hister certainly sounds like Hitler, and that second quatrain seems to drive it home. Actually, Many of Nostradamus’ predictions are about a guy from Germania who wages a great war and dies mysteriously.
What are the odds?
If any of this seems too amazing to be coincidence, too odd to be random, too similar to be chance, you are not so smart.
You see, in all three examples the barn was already peppered with holes. You just drew bullseyes around the spots where the holes clustered together.

Need help dealing with a conspiracist? Here you go. You’re welcome. – MIB
Delusional disorder is a mental illness called a “psychosis.” This is when a person can’t tell what’s real from what’s imagined. People who suffer from delusional disorder have fixed, unshakable beliefs in things that aren’t real — like being convinced that aliens are watching them or that they are close friends with celebrities. Unfortunately, delusions are hard to treat because the beliefs are so fixed. If you have a loved one with this illness, educate yourself and express your concerns, but also be ready to intervene in case of a serious situation.
Expressing Your Concern
1 • Pick a lucid moment to talk. One of the worst things you can do if you think a loved one is having delusions is to ignore it. You should reach out to your loved one while also considering how to contact his therapist (if he has one) or local mental health services for advice on treating delusional disorders.
- It’s OK to try to talk to your loved one about your concern, but pick a time when he is lucid. You may not be able to discuss your loved one’s mental state while he is actively having delusions.
2 • Frame your concern as an opinion. Talk to your loved one and express your anxiety about her behavior and thought patterns. It is important to remain conscious or your tone and not become angry or aggressive. Try at all times to be gentle, honest, and non-confrontational. You will probably not be able to convince her that her delusions are mistaken, even with clear evidence.
- Be as non-judgmental as possible. Delusions are “fixed ideas.” Saying, “What you’re thinking isn’t real,” or, “No, you’re being paranoid and crazy!” won’t accomplish much and could actually strengthen the person’s delusions.
- Present your concern as an opinion instead, i.e. “You seem to be having a rough time. I wonder whether you’re all right?” or “I’m concerned for you. My own opinion is that you’ve developed some fixed ideas.”
3 • Don’t play into the delusions. Avoid attempts to disprove your loved one but at the same time, do not play along with his delusions or make it seem like you agree. Try instead to connect to the person’s experience and understand him rather than refuting the delusion itself.
- Affirm that your loved one’s feelings are important while making it clear that you do not agree with him. Say something like, “I understand that you feel that way. I have a different opinion,” or, “What you’re talking about is important; I just think you could be mistaken.”
- You might also subtly question your loved one’s delusions with suggestions, i.e. “Strongly believing something is true doesn’t necessarily mean that it is true, don’t you think?” or “We’re all capable of misinterpreting things, aren’t we?”
- You could also try saying, “But our brains can misinterpret things and giving us the wrong idea, no?” or “Sometimes we can imagine things that seem very real — like dreams. That doesn’t mean they are real, though.”
9-11 was an inside job. The moon landing was faked. Vaccines cause autism. These are just a few of the most well-known conspiracy theories perpetuated by otherwise intelligent, everyday people. But why do some people believe these things and others don’t? Scientists are one step closer to figuring that out, and it appears that the answer lies within the brains of the theorists’ themselves, which affects how they see they world.
Scientists had long hypothesized that conspiracy theory belief (which the researchers of a new paper define as “the assumption that a group of people colludes together in secret to attain evil goals”) was due to a phenomenon known as “illusory pattern perception” — seeing patterns where none really exist. But few studies had been done to support this. So, the British and Dutch scientists conducted a series of experiments to fill that void. Their paper was published recently in the European Journal of Social Psychology.

To a conspiracy theorist, the world is not what it seems. Invisible threads link seemingly unrelated concepts, and there’s no such thing as a random coincidence.
Researchers have been scratching their heads for years over what makes some people more conspiratorially inclined. Now a recent study has finally tracked down one of the faulty thinking patterns. As it turns out, we all use it – but these people use it too much.
A team of psychologists from Vrije Universiteit Amsterdam in the Netherlands and the University of Kent in the UK has determined that conspiracy theorists are hooked on something called ‘illusory pattern perception’.
“People often hold irrational beliefs, which we broadly define here as unfounded, unscientific, and illogical assumptions about the world,” the team writes in the study.
“Although many irrational beliefs exist, belief in conspiracy theories and belief in the supernatural are particularly prevalent among ordinary, nonpathological citizens.”
In other words, conspiracy theorists are not “nuts”. They’re totally sane, which makes their beliefs all the more puzzling – until we realise that they actually see the world quite differently.
Illusory pattern perception is a pretty simple concept. It happens whenever we find a meaningful pattern in random stimuli, drawing correlations and even causation where none has actually occurred.
For example, you might have a dream about an elderly relative, and then receive news the following day that the relative has passed away. For some people that would be enough to conclude that their dreams can predict the future.
What are Barnum Statements (The Forer Effect)? Let’s uncover how psychics use the Rainbow Ruse and psychic number games to fool their victims. We’ll examine clips of Theresa Caputo, John Edward, James Van Praagh, Joe Power, Rosemary Altea, and other alleged psychics to expose psychic tricks and cold reading methods just as magicians/skeptics like Derren Brown, Paul Zenon, and James Randi have done before. Don’t fall for their tricks, stay skeptical and don’t drink the psychic Koolaid!
This scam involves making a series of opposite predictions (on winners in the stock market, football games, or the like) and sending them to different groups of people until one group has seen your perfect track record sufficiently to be duped into paying you for the next “prediction.”
For example, Notre Dame is playing Michigan next week, so you send 100 letters to people, predicting the outcome of the game. It doesn’t really matter whether the recipients of your letter are known to bet on college football games. The information you provide will stimulate some of them to want to bet on the game. You name your letter something swell like The Perfect Gamble. In 50 letters you predict Notre Dame will win. In the other 50 you predict Michigan will win. You write a short introduction explaining that you have a secret surefire method of predicting winners and to prove it you are giving out free predictions this week. Notre Dame wins.
The next week you send a free copy of The Perfect Gamble to the 50 who got the letter that predicted a Notre Dame victory. In the introduction you remind them of last week’s prediction and you inform them how much they would have won had they followed your advice. To show there are no hard feelings and to give them one more chance to take advantage of your surefire system you provide—free of cost—one more prediction. This week Notre Dame is playing Oregon State. You divide your list of recipients and you send 25 letters predicting Notre Dame will win and 25 predicting Oregon State will win.
After the second game, you will have 25 people who have seen you make two correct predictions in a row. Three correct predictions in a row should convince several recipients of your letter that you do have a surefire way to pick winners. You now charge them a substantial fee for the next prediction and, if all goes as planned, you should make a handsome profit even after postage and handling costs.
Since you are a crook for running this scam, you won’t feel guilty in promising the prospective suckers their money back if not completely satisfied with your predictions. Your hope is that they will be greedy and say: “How can I lose?” You needn’t remind them how. You might even be able to rationalize your behavior by telling yourself that they deserve to be scammed because they’re so greedy!
For different audiences, you can pretend to be a psychic or an astrologer or a mathematician or a gambler who knows how to fix college football games. If you are cheating the gullible as well as the greedy, you may be able to convince yourself that you are performing a beneficial service to the community by cheating these people out of their money. You might persuade yourself that rather than try to put you in jail for being a fraudulent scammer, society should give you an award for reminding people to use their common sense and critical thinking skills.
A variant of the perfect prediction scam is used by some psychics. If you tell enough clients “someday you will be rich beyond your wildest dreams,” then if one of them inherits a great sum or wins a lottery, you may get credit for being psychic.
There are many people who promote themselves as psychics or clairvoyants, and who claim that their powers enable them to read your character, make contact with dead relatives, or provide insights into your life and your future.
Despite their claims, there has never been a successful demonstration of these powers in a laboratory, under properly controlled conditions. Indeed, the National Committee of Australian Skeptics offers a cash prize of $100,000 for any PROVEN demonstration of such powers. See The Prize.
By far the most common method employed by psychics who have been put to the test is called cold reading. This method involves the psychic reading the subject’s body language etc, and skilfully extracting information from the subject, which can then be fed back later, convincing the subject that the psychic has told them things they couldn’t possibly have known!
The following is our 13 point guide to cold reading — Study them well, then amaze your friends with your new found psychic powers!
1. Remember that the key ingredient of a successful character reading is confidence.
If you look and act as if you believe in what you are doing, you will be able to sell even a bad reading to most subjects. One danger of playing the role of reader is that you may actually begin to believe that you really are divining your subject’s true character!
2. Make creative use of the latest statistical abstracts, polls and surveys.
These can provide you with much information about what various subclasses in our society believe, do, want , worry about etc. For example, if you can ascertain a subject’s place of origin, educational level, and his/her parents’ religion and vocations, you have gained information which should allow you to predict with high probability his/her voting preferences and attitudes to many subjects.
3. Set the stage for your reading.
Profess a modesty about your talents. Make no excessive claims. You will then catch your subject off guard. You are not challenging them to a battle of wits – You can read his/her character, whether he/she believes you or not.
4. Gain the subject’s cooperation in advance.
Emphasise that the success of the reading depends as much on the subject’s cooperation as on your efforts. (After all, you imply, you already have a successful career at character reading — You are not on trial, your subject is!) State that due to difficulties of language and communication, you may not always convey the meaning you intend. In these cases, the subject must strive to fit the reading to his/her own life. You accomplish two valuable ends with this dodge — Firstly, you have an alibi in case the reading doesn’t click; it’s the subject’s fault, not yours! Secondly, your subject will strive to fit your generalities to his/her specific life circumstances. Later, when the subject recalls the reading, you will be credited with much more detail than you actually provided! This is crucial. Your reading will only succeed to the degree that the subject is made an active participant in the reading. The good reader is the one who , deliberately or unwittingly, forces the subject to search his/her mind to make sense of your statements.
Use of props serves two valuable purposes. Firstly, it lends atmosphere to the reading. Secondly, (and more importantly) it gives you time to formulate your next question/statement. Instead of just sitting there, thinking of something to say, you can be intently studying the cards /crystal ball etc. You may opt to hold hands with your subject — This will help you feel the subject’s reactions to your statements. If you are using , say, palmistry (the reading of hands) it will help if you have studied some manuals, and have learned the terminology. This will allow you to more quickly zero in on your subject’s chief concerns — “do you wish to concentrate on the heart line or the wealth line?“
6. Have a list of stock phrases at the tip of your tongue.
Even during a cold reading, a liberal sprinkling of stock phrases will add body to the reading and will help you fill in time while you formulate more precise characterisations. Use them to start your readings. Palmistry, tarot and other fortune telling manuals are a key source of good phrases.
Some say they are tools by which demons can influence us; others regard them as mechanisms for communicating with the deceased; still others dismiss them as toys that can be used to fool your friends. But however we regard them, Ouija boards have left an indelible mark on our culture. But of most interest is the question they raise: Can they indeed be used to reveal information unknown to any of the participants whose hands rest on the pointer? Today we’re going to find out what the science has revealed about Ouija boards.
Historically, these are called talking boards, and they’ve been around in spiritualism almost as long as spiritualists. They all involve a planchette, which is the pointer that seance participants all place their hands on, which then moves. How does it move? Well, that’s the fun if it’s a game, and it’s the spirit if it’s a seance. The planchette can either point to letters, numbers, or symbols written on the playing surface; or it can hold a writing implement that moves over paper to produce so-called spirit writing, or automatic writing.
The Ouija board is the name of the most successful talking board that’s been manufactured commercially, first by the Charles Kennard Novelty Company in 1890, then by Parker Brothers since 1966, and by Hasbro since 1991.
It’s true that name Ouija is the French and German words for yes, oui and ja. That’s officially what the game’s publisher will tell you it means, and that comes all the way down from one of the original bosses of the company, William Fuld. But Fuld wasn’t the first, and before he came along, the founders had their own explanation for the name.
The story goes — and it is just a story, there’s really no record telling us how much truth there may or may not be to it — that two of the four founders, Charles Kennard and Elijah Bond, were hanging out at the boarding house where Bond’s sister-in-law lived, Helen Peters, and they were, of course, playing with their new invention.

Throughout history, there have been individuals who believe they’ve caught a sense of events yet to come.
True clairvoyance is unsupported by scientific evidence, but a subtle difference in how some people perceive the timing of events could help explain why many remain convinced of their psychic abilities.
A study by researchers from Yale University has provided some insight into why people think they have supernatural foresight, hinting at a physiological basis behind certain delusions.
The weight of evidence makes it fairly clear the human brain is not influenced by future events.
In many cases, proposed psychic abilities are the result of intentional fraud, with charlatans employing the same kinds of tricks mentalist magicians have used for centuries to feign mind reading and fortune telling.
But not all people who claim extraordinary abilities of future-sight are out to make a quick buck or two. Dismissing it as a sign of mental illness also tells us little about how such beliefs develop in otherwise healthy brains.
To gain an understanding of the neurological underpinnings of psychic prediction, the researchers made use of a test that had previously demonstrated a link between the timing of a colour changing shape, and the subject’s judgement of their ability to predict its transformation.
Only this time the researchers also evaluated the volunteers’ beliefs.

Do you believe the moon landing was faked? Do you suspect the 9/11 attacks were a government cover up?
Turns out, if you’re an avid conspiracy theorist, you could be doing it for attention.
According to new research, published in the European Journal of Social Psychology, some people like believing in conspiracy theories because of a need for uniqueness. In other words, they like to be different, and so take on beliefs that are out of the ordinary.
It’s similar to when people take up unusual hobbies that set them apart from others. That person on Reddit with a weird idea of what shape the Earth is could actually feel special or above average because they think they’ve figured something out that the majority of others haven’t.
Being in on the conspiracy theories may make people feel like they are part of a secret society that has all the answers.
To test this theory, a research team from Johannes Gutenberg University in Mainz, Germany conducted a series of studies to see how the need for uniqueness could prompt people to believe conspiracies more.
Believing one conspiracy theory makes it more likely you’ll believe another.
In the first study, 238 people were assessed for their need for uniqueness, and their endorsement of 99 conspiracy theories. The results showed that believing one conspiracy theory makes it more likely you’ll believe another, and that there was a correlation between this endorsement and the need to not follow the crowd.
History has shown any cataclysmic event in the world has resulted in not just grief and shock among the masses but a host of conspiracy theories also.
From the assassination of former U.S. President John F Kennedy to the death of Princess Diana, a member of British royal family; from the world-changing collapse of the twin towers in New York to the baffling disappearance of Malaysian Airlines flight MH370, people have never shied away from putting their own spin on the details of an event when the reasons from the authorities concerned have failed to satisfy them.
Some conspiracy theories have been simply outrageous, while others have offered a kernel of truth. But there’s no denying the fact that conspiracy theories strongly influence the outlook of a certain section of people. Now the question is why do people give in to these conspiracy theories?
A study published in the journal Social Psychology in July tries to answer this question by suggesting that the need to be special and unique drives the people to believe in conspiracy theories.
More than 1,000 people took part in the study titled “I know things they don’t know!” that was co-authored by Anthony Lantian, Dominique Muller, Cécile Nurra, and Karen M. Douglas of Grenoble Alps University. “An intriguing feature in the rhetoric of people who believe in conspiracy theories is that to justify their beliefs, they frequently refer to secret or difficult-to-get information they would have found,” Lantian was quoted as saying by psychology news website Psypost in a report published in August.
“This fascination for what is hidden, emerging from conspiracy narratives, led us to the concept of need for uniqueness,” he added.
The researchers found evidence to support three main tenets of their hypothesis:
VSauce does it again. Fascinating stuff.
Do you have precognition? If you’ve ever thought you might, you’re not alone. We all have experiences, at least every once in a long while, where it seems we’ve anticipated something a little too precisely for it to be random chance. Sometimes we anticipate things that are so specific, and so far outside the normal events we expect, that it seems there can be no explanation other than precognitive psychic powers. Might there be some undiscovered energy or force that makes such a thing possible? Today we’re going to look at your precognitive experiences, and see if there might be some other explanation.
First, it’s important to lay the groundwork for the conventional science-based explanation for apparent episodes of precognition. It comes from the law of large numbers. If we assume that something (anything) happens about once a second in your waking life, then statistically, you’re going to have a one-in-million experience about every month. Let’s take a look at the classic case as one example:
Hi Brian. At first, thank you for giving me the reasons and rationalities behind urban myths and superstition. I live in New Zealand and in 2015, my husband was on a business trip to Tokyo. On a Friday night, I dreamed about his funeral, no idea why, because he was a very healthy and happy man. The Saturday evening, my son called me that the police had come to tell him that they had found his father slumped next to his desk in his Tokyo hotel room. He had died the Friday night of a sudden heart attack. Due to the time difference between New Zealand and Japan, I must have had this dream at the same moment he died. I am not superstitious, but I hope you can give a reasonable explanation for my experience. Thank you, and keep up the good work.
Obviously this is an incomprehensible personal tragedy. Of course this listener has all our sympathies, but today we’re looking only at the statistical probability of what happened. I call this the classic case because it’s one of the most commonly reported cases that come to be described as psychic precognition: You dream of someone and then find out they died at that same time. But can it happen without psychic powers? Let’s calculate the probability of that.

My favorite exchange between the interviewer (Matt Shea) and one of the (alleged) targeted individuals (Shane) begins at 26:33 into the video:
Targeted Individual: Everybody gets a stroke of bad luck every now and then, but to have it continual, to have it continuous … something is going on here.
Matt Shea: Of course there are some people who are just really, really, really unlucky.
Targeted Individual: Would you say somebody defecating in my bed is unlucky?
Matt Shea: Why would … ?
Targeted Individual: Why would I shit in my own bed? Seriously.
Matt Shea: Why would the government shit in your bed?
Targeted Individual: Or, why would the free masons shit in my bed?
Matt Shea: Why would ANYONE shit in your bed?
Targeted Individual: Exactly. Why?

Some claim that certain common false memories are evidence for alternate realities.
Ever have one of those moments where you watch an old movie or pick up an old book, and hear a quote or see something that stands in stark contrast to what you thought you remembered? We all have. But what about a special case, where the exact same broken memory is shared by a large number of people? At first glance, it seems like this must be something different. It’s no surprise that any of us individually might remember something wrong; but for a whole group to share an identical false memory seems to suggest that there might be a new phenomenon at work. It’s been called the Mandela Effect.
The Mandela Effect is named for one of its most famous examples, that of Nelson Mandela, whose funeral some people remembered after he supposedly died in prison. Mandela was arrested in 1962 and sentenced to life in prison in South Africa, but he survived it and was released in 1990. He was President of South Africa from 1994 to 1999, and some of those same people said “Wait, he died in prison, I watched the funeral on TV.” He didn’t actually die until 2013; and every time his name came up, these same people said “Wait a minute, I thought he was dead.”
Now, this group who erroneously remembered that Mandela had died did not include me, but I’m sure some people thought he had. One who did was psychic ghost hunter Fiona Broome, who writes that she discovered that some people she knew also thought that Mandela had died. Seeking an explanation for what she described as an “emerging phenomenon”, she turned not to social science, but to some nebulous concept of alternate realities. In her own words:
The “Mandela Effect” is what happens when someone has a clear memory of something that never happened in this reality. Many of us — mostly total strangers — remember the exact same events with the exact same details. However, our memories are different from what’s in history books, newspaper archives, and so on. This isn’t a conspiracy, and we’re not talking about “false memories.” Many of us speculate that parallel realities exist, and we’ve been “sliding” between them without realizing it. (Others favor the idea that we’re each enjoying holodeck experiences, possibly with some programming glitches. In my opinion, these aren’t mutually exclusive.)
Is a lot of people remembering something wrong evidence for alternate realities? Not really.
From the video description:
Transcendent experiences that were once attributed to gods, angels, muses, or even possession, are now being demystified by neuroscience. Jamie Wheal, Director of Programs at the Flow Genome Project, explains that each culture has unique rituals and narratives when it comes to non-ordinary experiences of consciousness or ‘altered states’, whether that’s mediation, flow state, psychedelic experiences, or others. A farmer in India, a peasant in Mexico, and a coder in Silicon Valley will all have vastly different ways of approaching altered states, and will give vastly different descriptions once they come out the other side – perhaps they saw a vision of Ganesh the elephant God, received a message from the Virgin of Guadalupe, or produced a brilliant line of code while in a Matrix-like binary blur. However, those experiences are more alike than we think. Jamie Wheal and Steven Kotler devised a functional framework so they could compare non-ordinary experiences across cultures. Here, Wheal explains that they identified four common elements of altered states of consciousness, which they coined as STER: selflessness, timelessness, effortlessness and richness. Jamie Wheal and Steven Kotler’s book is Stealing Fire: How Silicon Valley, the Navy SEALs, and Maverick Scientists Are Revolutionizing the Way We Live and Work (goo.gl/m3Quy0).

Why can we find geometric shapes in the night sky? How can we know that at least two people in London have exactly the same number of hairs on their head? And why can patterns be found in just about any text — even Vanilla Ice lyrics? PatrickJMT describes the Ramsey theory, which states that given enough elements in a set or structure, some interesting pattern among them is guaranteed to emerge.
While humanity has yet to generate any universally-accepted proof of ghosts or hauntings, millions of people around the world report seeing apparitions or experiencing ghostly encounters every year (and sometimes these events cluster around specific areas). Why? Is there any possible explanation for the purported appearance of ghosts?

Every now and then an idea comes along that upends how we see ourselves and our place in the cosmos. The rumblings of the next revolutions in our thinking may already have started. Here are four potential “what ifs” with the potential to change us forever.
What happens in the brain when a person has an out-of-body experience? A team of scientists may now have an answer.
In a new study, researchers using a brain scanner and some fancy camera work gave study participants the illusion that their bodies were located in a part of a room other than where they really were. Then, the researchers examined the participants’ brain activity, to find out which brain regions were involved in the participants’ perceptions about where their body was.
The findings showed that the conscious experience of where one’s body is located arises from activity in brain areas involved in feelings of body ownership, as well as regions that contain cells known to be involved in spatial orientation, the researchers said. Earlier work done in animals had showed these cells, dubbed “GPS cells,” have a key role in navigation and memory.
The feeling of owning a body “is a very basic experience that most of us take for granted in everyday life,” said Dr. Arvid Guterstam, a neuroscientist at the Karolinska Institutet in Sweden, and co-author of the study published today (April 30) in the journal Current Biology. But Guterstam and his colleagues wanted to understand the brain mechanisms that underlie this everyday experience.
Rubber hands and virtual bodies
In previous experiments, the researchers had explored the feeling of being out of one’s body. For example, the researchers developed the so-called “rubber hand illusion,” in which a person wearing video goggles sees a rubber hand being stroked, while a researcher strokes the participant’s own hand (which is out of sight), producing the feeling that the rubber hand is the participant’s own. The researchers have used a similar technique to give people the feeling of having a manikin’s body, or even an invisible body, as they described in a report published last week in the journal Scientific Reports.
In the new study, Guterstam and his colleagues . . .

There is very good reason for all of humanity to have a healthy curiosity relating to near-death experiences. Death is the one experience we are all guaranteed to ultimately share. The field of science has therefore made numerous attempts to explain the near-death phenomena that so many people have independently described.
10 • The Temporoparietal Junction May Be Responsible For Out-Of-Body Experiences
Among the more common elements of near-death experiences is the distinct feeling of an individual having left their worldly body. Those who have had an “out-of-body” experience often report floating above themselves while being able to see their body and the people surrounding them. There have even been a few reports in which those who have had an out-of-body experience can identify objects and events occurring during times in which they were considered clinically dead, but there have also been studies demonstrating that this all could be due to damage in the temporoparietal junction of the brain.
The temporoparietal junction is responsible for assembling the data collected by the body’s senses and organs to form the perception of an individual’s body. When this part of the brain is damaged, it is possible that this results in the “out-of-body” experience that so many people have reported.
Though the experience may appear to be incredibly vivid and real, scientific studies have been able to reproduce this phenomenon without bringing the subject close to death, simply by electrically stimulating the temporoparietal junction of the brain.
9 • Excess Carbon Dioxide May Create The Tunnel And White Light
Nearly every individual who has had a near-death experience discusses the existence of a bright, white light and a tunnel that seems to lead to the afterlife. The white light seems to take on an otherworldly quality and is often accompanied by an overwhelming sense of peacefulness and welcoming.
A 2010 study of patients who had heart attacks revealed that there may be a correlation between this type of near-death experience and the level of CO2 in the blood. Out of the 52 cardiac patients studied, 11 reported a near-death experience. The levels of CO2 in the blood of those 11 patients were significantly higher than the patients who did not report having a near-death experience.
The feeling among researchers is that the excess CO2 in the bloodstream can have a significant effect on vision, which leads to patients seeing the tunnel and the bright light.
8 • Lack Of Oxygen To The Brain Causes Hallucinations
Many near-death experiences include the presence of long-dead friends and relatives appearing and perhaps even guiding the individual as they pass from the world of the living to the afterlife. Memories from every part of life are recalled in rapid succession, and there is an overwhelming sense of comfort, yet it appears that scientific research has provided an explanation for this phenomenon as well.
While excess CO2 has an effect on vision during a near-death experience, a lack of oxygen to the brain also plays a contributing role. It is well known that oxygen deprivation can lead to hallucinations and may even contribute to the feeling of euphoria that is often reported. While the sample size available to researchers is limited, studies have indicated that individuals who reported a near-death experience during cardiac arrest also had lower levels of oxygen.
Researchers believe that oxygen deprivation could well result in people “seeing their lives flash before their eyes” or being transported to a place where they are surrounded by friends and relatives who have long since passed on. This remains just a theory, however, as the other available research seems to indicate that multiple factors contribute to the near-death experience, which include the aforementioned CO2 levels as well. It makes sense in this regard that near-death experiences are commonly reported by those resuscitated following a heart attack, as a heart attack occurs when blood is blocked from reaching the brain.
