What Is An Illusion In Psychology?

Illusions in psychology: An interesting thing to mess with your mind – Illusions are the psychological factor that indicates a “misperception in the presence of stimulus”. There is a conflict between real fact and the mind that creates misperception. Illusions can happen because the “effect of light” on any object such as a rainbow is the cause of the refraction of light.

It is an illusion that happens in the atmosphere.
Magicians show magic by creating illusions but the audience interprets it as something real.
Various illusion examples can be used for entertainment.
In the science park, there can be a section where illusion is the main attraction and people observe it with their different perspectives.

Illusions in psychology are broadly used to indicate the inaccurate perceptions that occur for a sensory distortion. Illusions refer to powerful clues by which one can understand the way to process information in the brain. Illusion in psychology indicates that many people can be tricked by the optical illusion.

What is illusion in psychology with example?

Illusion, a misrepresentation of a ‘real’ sensory stimulus —that is, an interpretation that contradicts objective ‘reality’ as defined by general agreement. For example, a child who perceives tree branches at night as if they are goblins may be said to be having an illusion.

What is the psychological concept of illusion?

The psychological concept of illusion is defined as a process involving an interaction of logical and empirical considerations. Common usage suggests that an illusion is a discrepancy between one’s awareness and some stimulus.

What is the best definition of illusion?

: a misleading image presented to the vision : optical illusion. (2) : something that deceives or misleads intellectually. b(1) : perception of something objectively existing in such a way as to cause misinterpretation of its actual nature.

Is illusion the same as hallucination?

Abstract – Introduction: Visual hallucinations or illusions are not a rare symptom. However, they are often unrecognized. Unawareness of the meaning of these symptoms often mislead both the patient and his physician. Purpose: To define and describe the types of visual illusions and hallucinations which can be commonly encountered in neuro-ophthalmological practice.

Methods: Overview article.
Results: Hallucinations are a perception not based on sensory input, whereas illusions are a misinterpretation of a correct sensory input.
Both phenomenon can be due to medication or drug, or to an altered mental status.
Visual hallucinations can be formed (objects, people) or unformed (light, geometric figures).

They can be generated either by a lesion on the antechiasmatic pathway, by a seizure phenomenon, by a migrainous phenomenon, or by a release phenomenon secondary to visual differentiation. Investigations will be directed towards a retinopathy, an optic neuropathy, a chiasmal or retrochiasmal lesion, or a bilateral antechiasmal lesion (Charles Bonnet syndrome).

Visual illusions include meta-morphopsias, micro- macropsias, polyopia, palinopsia (visual perseveration), achromatopsia, Pulfrich phenomenon, or subjective vertical deviation. Illusions can be due to lesions of the retina, the optic nerve, the visual cortex (primary or associative), or the graviceptive pathways.

Conclusions: As most patients do not spontaneously mention their symptoms, history taking is essential. The first step is to rule out medication or an altered mental status as the possible cause of these symptoms. Then, careful visual function examination should provide a good insight in the location of the lesion.

How does Freud define an illusion?

Summary – Freud defines religion as an illusion, consisting of “certain dogmas, assertions about facts and conditions of external and internal reality which tells one something that one has not oneself discovered, and which claim that one should give them credence.” Religious concepts are transmitted in three ways and thereby claim our belief.

Firstly because our primal ancestors already believed them; secondly, because we possess proofs which have been handed down to us from antiquity, and thirdly because it is forbidden to raise the question of their authenticity at all.” Psychologically speaking, these beliefs present the phenomena of wish fulfillment, “fulfillments of the oldest, strongest, and most urgent wishes of mankind.” (Ch.6 pg.38).

Among these are the necessity to cling to the existence of the father, the prolongation of earthly existence by a future life, and the immortality of the human soul. To differentiate between an illusion and an error, Freud lists scientific beliefs such as ” Aristotle ‘s belief that vermin are developed out of dung” (pg.39) as errors, but “the assertion made by certain nationalists that the Indo-Germanic race is the only one capable of civilization” is an illusion, simply because of the wishing involved.

Put forth more explicitly, “what is characteristic of illusions is that they are derived from human wishes.” (pg.39) Freud adds, however, that, “Illusions need not necessarily be false.” (pg.39) He gives the example of a middle-class girl having the illusion that a prince will marry her. While this is unlikely, it is not impossible.

The fact that it is grounded in her wishes is what makes it an illusion. Freud explains religion in a similar term to that of totemism, The individual is essentially an enemy of society and has instinctual urges that must be restrained to help society function.

Among these instinctual wishes are those of incest, cannibalism, and lust for killing.” (pg.10) Freud’s view of human nature is that it is anti-social, rebellious, and has high sexual and destructive tendencies, The destructive nature of humans sets a pre-inclination for disaster when humans must interact with others in society.

“For masses are lazy and unintelligent; they have no love for instinctual renunciation, and they are not to be convinced by argument of its inevitability; and the individuals composing them support one another in giving free rein to their indiscipline.” (pg.7) So destructive is human nature, he claims, that “it is only through the influence of individuals who can set an example and whom masses recognize as their leaders that they can be induced to perform the work and undergo the renunciations on which the existence of civilization depends.” (pg.8) All this sets a terribly hostile society that could implode if it were not for civilizing forces and developing government.

Freud elaborates further on the development of religion, as the emphasis on acquisition of wealth and the satisfaction of instinctual drives (sex, wealth, glory, happiness, immortality) moves from “the material to the mental.” As compensation for good behaviors, religion promises a reward.
In Freud’s view, religion is an outshoot of the Oedipus complex, and represents man’s helplessness in the world, having to face the ultimate fate of death, the struggle of civilization, and the forces of nature.

He views God as a manifestation of a childlike “longing for father.” (pg.18) Freud’s description of religious belief as a form of illusion is based on the idea that it is derived from human wishes with no basis in reality. He says, “Thus we call a belief an illusion when a wish-fulfillment is a prominent factor in its motivation, and in doing so we disregard its relations to reality, just as the illusion itself sets no store by verification.” In Freud’s words “The gods retain the threefold task: they must exorcise the terrors of nature, they must reconcile men to the cruelty of Fate, particularly as it is shown in death, and they must compensate them for the sufferings and privations which a civilized life in common has imposed on them.” (pg.19)

Why do illusion occur in psychology?

Answer: – Illusions occur because of a result of a mismatch between the physical stimuli and its perception by the individual. The mismatch is caused by incorrect interpretation of information received by sensory organs. Illusions are called primitive organisations as they are generated by an external stimulus situation that generates the same kind of experience in all the individuals.

Why do illusions happen?

But how and why? – A lot of scientists have worked very hard for many years trying to understand how optical illusions work. But the truth is, in many cases, we still don’t know for sure exactly how our brain and eyes work together to create these illusions.

We know that information that our eyes gather goes on a long, complicated journey as it travels to the brain.
Some of the confusion happens early in that journey.
Other optical illusions can only be explained by really complicated processes way down the line in that journey.
In general, the further down the line these “confusions” occur, the less scientists tend to know about exactly how they happen.

But who knows? Maybe you will grow up to be part of the research team that cracks the code. This article is republished from The Conversation under a Creative Commons license. Read the original article,

What is illusion vs reality?

Illusion — an instance of a wrong or misinterpreted perception of sensory experience. Reality — the state of things as they exist, as opposed to an idealistic or notional idea of them.

What is a simple example of illusion?

What is an illusion? – The illusion is the misperception or misinterpretation of an individual that comes from a real object.E.g. the perception of a coil of a rope in darkness as a snake. It occurs because of confusion, eye movement, emotion, contrast perception, habits, defects of the sense organs, and a tendency towards the wholes.

Perception provides a clear and meaningful picture of the world around us and shapes our perceptual experience. However, sometimes the brain’s effort to organize sensations into coherent and accurate percepts fails. This is the cause of perceptual illusions in which normal perceptual processes produce perceptual misinterpretations.

The perceptual illusion is a false perception. It is due to misinterpretations or misperceptions of stimuli that do not correspond to the sensations received by the eye or other senses. For example, the grass looks greener on the other side of the fence. Similarly, as we mentioned, the perception of a coil of a rope in darkness as a snake is another example of illusion. The stimulus is exactly like that coming from a snake and it is quite real and objective. Our past experiences, our fear, and the darkness help to perceive the rope as the snake because the rope and snake have similarities in structure except living and non-living stimulus.

Are illusions just visual?

Visual Illusions and Optical Illusions Are Not the Same

The terms “visual illusion” and “optical illusion” are often used interchangeably but they describe distinct phenomena. An optical illusion has to do with how light interacts with matter to create a perception that does not correspond to reality. A visual illusion is caused by the brain. The visual system makes educated guesses, which can create perceptions that differ from reality.

Most people use the terms “optical illusion” and “visual illusion” interchangeably, much like “fluid” and “liquid” or “sofa” and “couch” are synonyms. At first glance, this might be seemingly pedantic in the extreme – par for the course for a society that is increasingly engaged in playing language games.

What is life’s biggest illusion?

Life’s greatest illusion | TheCable During a conversation with friends about how they wish they had never made certain mistakes, and thus, had the perfect life, I got thinking. ‘Can you really live life in absolute perfection?’ I asked myself. Of course not, even celebrities who are worshipped have mistakes and trials of their own.

It’s life’s greatest illusion, that mistakes in general make a person worthless, and live a life less than beautiful. In the words of John W. Gardner, ‘Life is the art of drawing without an eraser’. I know for a fact that drawings are a masterpiece in themselves. Maybe, it all just depends on our perception of it.

I do remember sharing the mentality of my friends. Growing up with a very meticulous person for a mother, she ensured everything was done with pure perfection. The way she laid the bed in the morning made me feel as though if I didn’t carry out that action in that exact way, my whole day would be in ruins.

Every detail mattered to her. For as long as I can remember, her greatest policy was ‘anything worth doing at all, is worth doing well’. Thus, I made it an unfailing duty to have the perfect diction, be polite in every way, imbibe the proper eating and walking etiquette. Honestly, there were countless times in which I was frustrated to say the least but what kept me going was my ‘amazing’ mentality of not making mistakes.

To me, these perfections I had imbibed gave me an assurance of a paved way in life. With an increase in age, came a stronger perception of perfection. More often than not, I found myself looking down on people who didn’t seem to want to be as apt as I was.

I felt as though, they were headed the south direction of life. Little did I know I was the one at fault for having these thoughts. Although, I never once made my opinions obvious to them. You know, thinking about it now, I was a prisoner to this illusion. There was a constant strive in me to be the perfect daughter, student, chorister and sister.

It became so ridiculous that whenever I did little things to alter my ‘drawing’, I felt I had gone in the totally wrong direction and would never be able to achieve my goal again. Fortunately for me, my mentality, actually my life, took a 360 degree turn.

I had just recently got my academic report for the session, and to say I performed woefully is an understatement.
It was as though my life flashed before my eyes because my parents and I were banking on this result to get me admitted at the university of my dreams.
At the time, in all my 15 years of life, I had never seen my mum so disappointed.

There was a switch within me, and I felt myself drowning in my fault. So, I gave up on being perfect at everything. I became like the people I once looked down upon. However, a while after, I stumbled upon a Youtube video on the life of Oprah Winfrey; how her past mistakes don’t reflect who she is today.

Prior to me watching this, I’d never have thought someone who has her life together, would have had a less than perfect childhood. But it truly was an eye opener; it was the light in the midst of my darkness. I began to open up my heart to a different way of life and till today, it’s one of my best decisions ever.

Many people are still under this delusion. At this point, you’re basically just walking the face of this earth; existing and not actually living. Simply because, you’ve done something(s) so grave, you don’t want to accept it and thus, you bury yourself wholeheartedly.

But why are you crying over spilt milk? It’s not that your tears will turn the hand of the clock back in time, nor will it gather the milk back into the bottle.
What’s done is done.
Take responsibility for it, accept it, learn from it, move on and never look back.
Yes, I agree.
Easier said than done but trust me, I’ve been there and wallowing in self-pity isn’t the better choice.

This illusion has crept so much into our world that it’s a two-way thing. It’s either you feel worthless for the past or you already feel you’ll be that way if you don’t get something you want out of the future. For others, it isn’t that they’ve made mistakes so grave making them feel worthless.

Rather, they have so many laid down perfect plans for the future and thus, feel like if any of these plans are altered, their life is going to be less than beautiful.
I remember when I was first ‘saved’ from this deceit, I asked my mother why she was so meticulous, why she was so perfect and thus, wanted me to be the same.

She laughed at me and as clear as day she said, ‘There’s no such thing as perfect’. All along, my mother just wanted me to be the best I could because she saw potential in me. Thinking about it now, there was actually not a moment I made a mistake and my mother made me feel worthless.

Yes, she’ll be disappointed and give me the cliché line of her expecting more from me, but she didn’t make it seem as though that was the only chance I had in life.
All along, I just assumed she was all for perfection but I misunderstood the whole situation.
Life is an adventure; an uncertain journey of self-discovery.

You can’t make plans and expect that everything would work out just the way you pictured it in your head. I’m not saying you should not have an idea of where you’re going in life, but also be sure to open yourself up to other opportunities and lifestyles.

Maybe the plan you have for yourself isn’t half as good as the one life wants to give you on this beautiful adventure. This doesn’t make you any less worth, nor does it mean your life wouldn’t turn out just fine. Honestly, you’re not meant to have everything figured out down to the last detail. There’ll be bumps in this long ride called life but you’ve got to trust that your journey will lead to a beautiful destination.

The series, ‘One Tree Hill’, says it better than I do, ‘It’s the oldest story in the world. One day you’re planning for someday. And then quietly, without you ever really noticing someday is today. And that someday is yesterday, and this is your life’. So much of the time, we’re so bent on planning our lives that we forget to actually live it and be in the moment.

We look back and see that what we spent years planning for, we weren’t able to enjoy it because we were too busy planning for the next day.
This was me, until I realized that things change, people change; friends you think you’ll have for a lifetime, you don’t even know where they are today.
For a while now, I’ve tried to study why many people are prisoners to this life’s greatest illusion.

I found that, it has much to do with comparison. For me, it was my mother I compared myself to, trying to be like her when she was just doing what she knew how to do best. As humans, we compare ourselves to the next person. That celebrity you adore so much, she knows how to sing so much that millions can stop and listen.

But you, your dad is always telling you to stop making noise. Wow! You feel you can’t make it in life because why does one person have it so easy and you can’t even get past your house? You forget to remember that it’s that celebrity’s calling in life and not yours. There’s something you can do that she is struggling with.

But, you rather just be like that person not taking into cognizance that the path destined for you is better than any other path you decide to take for yourself. The fact is that life is an exam, everyone has their own different paper. So, trying to copy someone who is doing well might just be a fail in your own books.

A lot of the time, you face battles and so, compare yourself to the person or rather, celebrity who seems to have everything in their life going fine.
Little do you know that they are going through worse things than you can imagine but are good at keeping everything inside.
So yes, it’s life’s greatest illusion; probably the most believable lie that mistakes in general make a person worthless and live a life less than beautiful.

What makes your life beautiful isn’t how ‘perfect’ you were but how you were able to rise above your mistakes and imperfections. More often than not, artists make mistakes or do things that they didn’t plan for when drawing, but they learn to make their mistake fit in with their masterpiece.

Thus, creating something even more beautiful than they originally intended.
If only we lived our lives with this mentality.
As said earlier, it’s true that every drawing is a masterpiece.
Every life is beautiful, it’s just up to you to see the beauty and uniqueness in every life, in your life.
Be filled with gratitude and not regret for the drawing you are creating and building every day.

There’s this quote that summarizes it all ‘ Put on your dancing shoes and skills. Dance like there’s no past to remember, no worries for tomorrow. Live in the present and soon enough, you’ll realize that contrary to what you thought, your dance is endless’.

Once you remove the hold of this illusion from you, you’ll come to know there’s much more to life than mere perfection because in fact, there’s no such thing.

Is illusion a psychosis?

Degraded Stimulus Continuous Performance Test (DS-CPT): – For a detailed description of the task, please see Nuechterlein & Asarnow, The task consists of a CPT with both task stimuli and background visually degraded: 40% of white numeral pixels are switched to black, and 40% of black background pixels switched to white.

Sensory control trials are administered consisting of “just look” (participants instructed to look passively at the screen) and “press every” (participants instructed to respond to each stimulus) at 80 trials each. Following a practice block, subjects then receive DS-CPT instructions and complete three experimental blocks wherein 25% of stimuli are targets (“0”) while the remainder are nontargets (numerals “1” to “9”).

Previous work has demonstrated that reduced perceptual sensitivity to target stimuli differentiates schizophrenia from bipolar disorder, and that first-degree relatives of patients with schizophrenia have a larger number of false alarms to stimuli that share contours with targets (numerals “6”, “8” and “9”), suggesting impaired contour detection in individuals with genetic liability for psychosis,

Is illusion a delusion?

Summary – Is it illusion or delusion? Both illusion and delusion are nouns.

An illusion is a misperception resulting from a trick of the senses, or something that is not as it appears. A hallucination is one type of illusion. A delusion refers to a dangerously deceptive idea,

Generally, delusion is only used in contexts that involve a dangerous idea. Since delusion and dangerous both begin with the same letter, this usage should be simple to remember. For other contexts, illusion is a better choice. Remember, if you get confused when choosing delusion or illusion in your writing, you can reference this site in the future.

What happens when you see an illusion?

Your senses gather information and send it to your brain. But your brain does not simply receive this information— it creates your perception of the world. This means that sometimes your brain fills in gaps when there is incomplete information, or creates an image that isn’t even there!

What is the philosophy of illusion?

Definition – Illusionism as discussed here, holds that people have illusory beliefs about, Furthermore, it holds that it is both of key importance and morally right that people not be disabused of these beliefs, because the illusion has benefits both to individuals and to society.

Belief in, argues Smilansky, removes an individual’s basis for a sense of self-worth in his or her own achievements.
It is “extremely damaging to our view of ourselves, to our sense of achievement, worth, and self-respect”.
Neither compatibilism nor hard determinism are the whole story, according to Smilansky, and there exists an ultimate perspective in which some parts of compatibilism are valid and some parts of hard determinism are valid.

However, Smilansky asserts, the nature of what he terms the fundamental dualism between hard determinism and compatibilism is a morally undesirable one, in that both beliefs, in their absolute forms, have adverse consequences. The distinctions between choice and luck made by compatibilism are important, but wholly undermined by hard determinism.

Which philosopher said that reality is an illusion?

Albert Einstein once quipped, “Reality is merely an illusion, albeit a very persistent one.” The famous scientist might have added that the illusion of reality shifts over time. According to a new Brandeis University study, age influences how we perceive the future.

When thinking about the future, some people seem pessimistic, while others’ optimism seems to border on fantasy.
Whether a person is naturally a pessimist or an optimist, the study suggests there are other factors at work in determining the way people consider how satisfying their future lives may be.

Brandeis University psychologist Margie Lachman along with Christina Röcke, University of Zurich, Christopher Rosnick, Southern Illinois University, and Carol Ryff, University of Wisconsin, wanted to see if there were differences in actual and perceived ratings of how satisfied Americans were with their lives over a nine-year period.

To test this idea, the researchers conducted two surveys, the first in 1995-1996, and the second nine years later, between 2004 and 2006. In the first survey, participants (between the ages of 24-74) completed a telephone interview and questionnaire. They were asked to rate how currently satisfied they were with their lives, how satisfied they were with their lives 10 years earlier and how satisfied they expected to be 10 years later.

In 2004, the participants were asked those same questions. The experiment enabled the researchers to measure how closely the actual life satisfaction ratings matched the perceived ratings (those from the past or 10 years into the future). With both sets of questionnaires in hand, Lachman and her colleagues were able to compare how subjects felt during the second survey with how they had predicted they would feel at that time.

The results suggest that there are age-related differences in how we view the past and the future.
Older Americans (65 and older) viewed the past and the present as being equally satisfying, but believed that the future would be less satisfying than the present.
Americans younger than 65 viewed the present as more satisfying than the past and were more optimistic about the future than their older counterparts, believing they would be more satisfied with life in ten years.

When comparing both sets of questionnaires, Lachman and colleagues discovered that younger and middle-aged adults showed great illusion (that is, they had major differences in their ratings): Both groups believed life would be better than it turned out to be.

Older adults, on the other hand, were more realistic and gave accurate predictions about how satisfied they would be.
Moreover, older Americans were consistent in how they viewed the past compared with how they actually answered at that time (during the first survey).
The older adults appeared wiser with greater self-knowledge and a more astute sense of their past and future feelings; they may strive for acceptance of present circumstances as a way of regulating emotions,” said Lachman.

The researchers also concluded that across all age groups, “being realistic about the past and future was associated with the most adaptive functioning across a broad array of variables including good health, a well-adjusted personality, supportive social relationships, high well-being and perceived control, and the absence of depression.” In short, those who were doing well were less likely to imagine that things are going to get even better.

This research has interesting implications for goal-setting and motivational behavior. These results suggest that younger adults’ optimism about the future motivates them to try to achieve high levels of satisfaction. The research also shows that older adults are not as sanguine about the future as younger adults, perhaps because they have become aware or have experienced the height of life satisfaction and may realize this is as good as it gets.

The authors suggest that older adults may be satisfied as long as they can maintain the status quo while they prepare themselves for future losses. “These more negative expectations from older adults may be their way of bracing for an uncertain future, a perspective that can serve a protective function in the face of losses and that can have positive consequences if life circumstances turn out to be better than expected,” says Lachman.

How do illusions affect behavior?

Summary: Moral illusions can fool our decision-making, making us more selfish, a new study reveals. Just as optical illusions can fool the eye to present a distorted image of reality, moral illusions can fool our decision-making ability, making us more selfish.

What are the 4 types of illusions?

James Turrell, Alta (Pink) as part of “Cosmic Wonder” at San Francisco’s Yerba Buena Center, 1968. This piece shows how Turrell challenges the viewer into questioning whether that is just light or something more physical, even something that you could potentially touch,

Many of James Turrell’s works attempt to make light, something wholly non-physical, cross the standards boundaries of perception into an almost physical and material realm, The dramatic color and light saturation that dominate his pieces suggest an entirely new way of experiencing light that goes beyond the mere visual sense.

An example of a literal optical illusion where the image created is different from the objects. It is seeing an image that you normally would not see in that context.

But what are optical illusions ? Here’s a real life example of optical illusions by Mike Hewson, a public art commission in New Zealand that pays homage to the Christchurch Normal School, a building slated for demolition after the 2011 earthquake, Can you tell which type(s) of optical illusions Hewson is working with from the three categories below? Types of optical illusions Literal, physiological, cognitive

An example of a physiological optical illusion, which are most commonly characterized by the afterimages after looking at bright lights. This type of repeating or intense stimulus leads us to falsely perceive movement or repetition. Jeremy Hinton created this illusion around 2005 — if you stare at the center cross for about 20 seconds, then you see three things: (1) a gap running around the circle of lilacs, (2) a green disc that joins the running purple lilacs, and (3) the green disc moving in the circular pattern and the lilac discs disappear ( image source ).

20th Century Analytic philosopher Ludwig Wittgenstein’s famous duck-rabbit picture to demonstrate the distinction between “seeing as” and “seeing that” or, an example of a cognitive visual illusion, There is no correct answer to whether this is a drawing of a duck, or a rabbit. Cognitive illusions are a result of our conceptions and assumptions about the world, which we impose upon visual stimuli. This can lead to four types of cognitive illusions: ambiguous illusions, distorting/geometrical-optical illusions, paradox illusions, or fictions ( image source ).

Types of cognitive optical illusions Ambiguous, distorting, paradox, fiction

The most common interpretation of the Necker Cube, an ambiguous cognitive illusion ( image source ).

A less common but equally plausible conception of the faces of the Necker Cube.

The Necker Cube is a well known example of an ambiguous illusion, The arrangement of the lines themselves are ambiguous, meaning nothing in the lines themselves suggest for the lower left face to be the “front” face. Computers do not have the same consistency as humans do in seeing this “front” face, rather, they see other interpretations with equal frequency.

The full moon illusion, a distorting cognitive illusion,

“The Café Wall” as n example of a geometric distorting cognitive illusion because of the arrangement of the lines and shading that make it seem like the lines are not straight when in fact they are.

Distorting illusions are some of the most common because they happen in everyday life as well as in geometric/artistic constructions. The photo on the left of the moon illustrates how our eyes are not equipped to see the true size of the moon, rather it depends on where the moon is in the sky.

The Penrose Stairs, an example of paradox cognitive illusion. This 2-dimensional depiction of a staircase has a 90º turn to form a continuous loop, where you would not get any higher or lower whichever step you take ( image source ).

Paradox illusions are caused by images that cannot exist in real life, but our minds accept them, at least at first, to be convincing. The Penrose’s, father Lionel and son Roger, (no relation to Spencer and Julie Penrose) invented the most famous paradox illusion of the Penrose Stairs.

Fiction illusions occur most commonly in hallucinogenic drug users, schizophrenics and others with disorders that cause hallucinations. These illusions are perceived only by the subject, and not anyone else. To see more examples of how our eyes can trick us, here’s an online gallery of more optical illusions.

What are real life examples of illusion of knowledge?

January 24, 2011 / in Blog / If you have a teenager, or have raised one, then no doubt you’re familiar with the phrase, “I know!” It seems like no matter what you say the response is almost always the same, “I know!” You might say, “Clean your room,” and it’s met with, “I know!” Or how about this, “You need to study before you can go out,” and they say, “I know!” If only we were as smart as our kids because they seem to know everything.

I recently read an interesting book, The Invisible Gorilla, by Christopher Chabris and Daniel Simons. In it they talked about something called “the illusion of knowledge.” This describes the tendency of people to think they know more than they really do. For example, almost everyone who drives a car would say they know how a car works, but they really don’t.

It’s readily apparent when raising teenagers that we are all subject to the illusion of knowledge to one degree or another. When it comes to getting people to do what you want – and hopefully avoiding the dreaded “I know!” – I have a persuasion tip that can help.

Here it is; stop making statements and start asking questions, Pretty simple and yet very effective. Questions are more effective when trying to persuade another person than making statements, because asking questions engages the principle of consistency, This principle of influence tells us people generally feel better about themselves when their words and deeds match.

Psychologically it’s hard on most people when they appear inconsistent to others and as a result they feel bad. Have you ever had to back out on your word and felt bad? We all have and we sometimes feel a little bad even if our reversal is completely justified.

We usually go to great lengths to avoid feeling bad so we live up to our word.
When you ask someone a question and they say “yes,” social psychology studies show the likelihood that they’ll do what they said they would goes up significantly.
And it’s not very hard to do.
Here are some examples: Statement – I need the board report by Friday.

Question – Can you get me the board report by Friday? Statement – You need to empty the dishwasher. Question – Will you empty the dishwasher? While it’s a simple concept it’s sometimes hard to put into practice. In fact, most of the principles of influence are easy to understand because people can easily recall a time when they unknowingly used a principle successfully or responded to someone who used a principle on them.

However, knowing and doing are two different things and when I lead the Principles of Persuasion workshop, participants always struggle to actually put the principles into practice. My advice is to take some time periodically to think about how you’re communicating; analyze a conversation after the fact to see where you might have used some questions rather than making statements.

Or better yet, before you hit the send button on your next email do a quick reread specifically to see where you could change statements to questions. I started this post talking about kids and the illusion of knowledge. While the point of this week’s article wasn’t the illusion of knowledge, reading about it triggered my thoughts for this post and I can highly recommend the book.
