The User Illusion: Cutting Consciousness Down to Size Paperback – August 1, 1999
Purchase options and add-ons
“Finally, a book that really does explain consciousness.”—John Casti, scientist and author of What Scientists Can Know About the Future
With foundations in psychology, evolutionary biology, and information theory, Demark’s leading science writer argues a revolutionary point: that consciousness represents only an infinitesimal fraction of our ability to process information. Although we are unaware of it, our brains sift through and discard billions of pieces of data in order to allow us to understand the world around us. In this thought-provoking work, Norretranders argues that our perceptions are not direct representations of the world we experience, but instead, illusions our brains craft to process it.
More timely and relevant than ever, in light of rapid development in artificial intelligence and large language models, this informative study of consciousness provides the framework to reflect on the inner workings of the mind and understand the self. As engaging as it is insightful, this important book encourages us to rely more on what our instincts and our senses tell us so that we can better appreciate the richness of human life.

- Reviewed in the United States on November 19, 2023I found this book very interesting. I can see this being one of those love it or hate it books. No in between. It gets deep into phycology, development of human thinking, the connection between vision and what we think, evolution of why we have certain fears, etc. I will read this again.
- Reviewed in the United States on November 20, 2023So much so that my original, with passages highlighted and underlined, paragraphs circled, etc…, has become nearly illegible and I had to buy another one!
The story he tells of James Clerk Maxwell on his deathbed is written so poignantly; last time I reread it, which was yesterday, it ‘almost’ made me cry.
I only wish I could tell him in person of the impact and importance of this book in my life, but thus far I have been unsuccessful. Perhaps this review will suffice.

- Reviewed in the United States on March 15, 2017Sure, the author takes a while to get onto the subject of consciousness, but I found the early detour on thermodynamics and information theory to be interesting in its own right. The author a has a penchant for being scrupulously thorough in his discussion of a subject, whatever subject that may be, and I therefore found the book to be extremely satisfying. Eventually, he does find his way to the subject of consciousness, and the thorough discussion of Benjamin Libet's brain stimulation experiments was much appreciated. These experiments had been referenced in other books I've read, but here the experiments and their implications were discussed in detail. Overall, this was a great read. (Hardcopy Edition)
- Reviewed in the United States on August 25, 2009This book should be used as educational resource material as early as it can be appreciated.... I'm almost certain that very few that have this kind of responsibility would agree with me, since it would overturn so much of the current mythology of the "I/Me".. As a species that has adopted a sort of self destructive brinkmanship as its culture, based on a simple misunderstanding of the nature of our cognitive processes, we could stand a little help with a reassessment of both where our strengths and weaknesses lie in how what we call the "I/Me" actually works...
The author has done an excellent job bringing to our attention both the miraculous and deceptive nature of perception and shows many examples of how to begin an examination of these issues for ones self, if so inclined...
- Reviewed in the United States on January 10, 2002First, I must agree that the first hundred pages are tough going and the last chapters may get too metaphysical, but the central theme of the book that our brain presents us with a user interface much like a computer does -- delayed in time, compressed, summarized, edited, incomplete -- has not been discounted in the ten years since the book was written. In fact, more and more experiments reveal the truth of this view. In a December 2001 Nature letter (Nature 414, 302 - 305, Illusory perceptions of space and time preserve cross-saccadic perceptual continuity), another experiment showing that our unconscious gives us delayed and edited information confirms that we exist in a User Illusion. Many of our behaviors, phobias, neuroses, psychoses, and human interactions can be analyzed in terms of this powerful illusion. And learning to understand and program our unconscious is the purpose of life.
- Reviewed in the United States on June 5, 2012I recently bought and read this book convinced it was a recent work. As it turns out it is a recent translation of an original published in the early nineties and my notion was surely enforced by the number of recent books on the same "theme" namely the apparently novel revelation that the greater part of our mental activity is not directly accessible to our consciousness! This is the bottom line of such instant best-sellers as "Subliminal: How Your Unconscious Mind Rules Your Behavior" by Leonard Mlodinow, "The Power of Habit: Why We Do What We Do in Life and Business" by Charles Duhigg, Jonah Lehrer's "Imagine: How Creativity Works" and, perhaps to a less extent, "Ignorance: How It Drives Science" by Stuart Firestein! There is clearly some trend here as James Atlas underscored it in a recent opinion column of the NYTs where he labelled these "Can't-Help-Yourself" books. That may be a bit harsh but what I find more intriguing is that all of these people appear genuinely surprised by a finding that is over 100 years old harking back to Sigmund Freud who made his fame by plunging psychology into the depths of the unconscious. Remember? In any case Tor Norretranders appears to have had one hand and a couple of decades on all these noveau retro-sensationalists and his book is a worthy read even if long and often repetitive. He covers an impressive amount of research covering the last quarter of the 20th century and manages to tie it together though the devices he introduces for the purpose are shallow and mostly misapplied. The first is the word "exformation" which is meant to designate the information that is discarded by a physical system, a correlate of Brilloin's Negentropy which was meant to label successfully eliminated entropy. Unfortunately for both it is quite self-defeating to try to define a system in terms of something that it no longer contains. The same can be said about his revival of that old William James' canard, the distinction between the I (conscious) and the Me (unconscious). Norretranders uses and abuses it to the point that these two sound more like an old married couple bickering about who is in control! Even Freud showed a bit more finesse introducing a distinction between the Ego, the Id AND the SuperEgo! Finally, his appropriation of the User Illusion, a term from software engineering, quickly fizzles maybe because the author did not really know what to do with it. Still most of the many subjects he addresses remain interesting as one can gather from this new wave of writing on the subject though my guess is that these people should have read Norretranders before they penned their own versions of his material. In spite of the problems I list the book is worth the effort or I would not have finished it.
In full disclosure I should point out that, in the middle of reading "The User Illusion" I recalled, from a particularly memorable anecdote it tells, that I have met the author -- in fact had lunch with him -- long time ago, during the first Workshop on Artificial Life in Los Alamos in 1987 or so. What little I remember of my interaction with him left me a positive impression which probably propelled my reading beyond the annoyances I describe. I recall that most of the scientists did not payed much attention to him but were quite impressed with the fact that James Gleick was also attending and he was using an intriguing new device that was to be later named a "laptop computer". Given that Gleick just published "The Information" which, again, appears to cover most of the same terrain, I can't help feel a bit more admiring of Norretranders! Unfortunately neither he nor Gleick seem to realize that the scientific notion of Information is, by itself, quite uninformative! They are not alone in this...
- Reviewed in the United States on July 25, 2020This is simply an extraordinary book, one of the most instructive I've run across in 71 years. I note one review says it was life-changing. That's not hyperbole. I've read it three times, and I'm ready to read it again. I still have my hardcopy, but a Kindle version would be to die for. Make it happen, Amazon.
- Reviewed in the United States on December 5, 2024I was looking forward to reading this then I opened the package, probably won't return it because it already took super long to get it. Major bummer of a product experience.

BVReviewed in the Netherlands on November 1, 20242.0 out of 5 stars A weird book that feels like it was printed at home
I ordered this book because no local bookstore carries it. I was interested in the topic and it was recommended by a friend. When I got the book, the leaves feel like soft/damp regular paper you would use in a cheap print shop. The text also had some letters welded together, it looks like the printer bleeding out on the book paper, which does not feel or look like your typical book paper. The cover felt underwhelming and was printed on black & white cardboard. The only thing that looks and feels right is the spine. I'm not sure if this is normal since I have other Penguin books I've purchased before. This was a weird purchase. I do not recommend.

RomuloReviewed in Brazil on August 1, 20215.0 out of 5 stars Uma, aliás várias provocações pertinentes e válidas para o mundo atual
Não é exatamente um livro "fácil": tem partes que exigem um parar, refletir e reler. Prepare-se para passar semanas intrigado. São conceitos na média complexos, mas as provocações trazidas mais de 20 anos atrás ainda ressoam em minha mente. Se eu disser a você que um texto pode estabelecer uma relação entre consciente, inconsciente, neurociência, entropia / termodinâmica, teoria da comunicação e livre arbítrio, é provável que não acredite, mas é exatamente o que acontece. Acho inclusive que chegou a hora de ler novamente. É uma delícia, principalmente se sente-se confortável com uma pegada mais "científica". Acredito que exatamente por esse motivo ele não seja tão conhecido, uma pena.
