Customer Reviews

Engaging, conversational tone that makes the book a breeze to read.
Book Shark
This fascinating book explores the optimism bias--the tendency to overestimate the probability of positive events and underestimate the probability of negative ones.
In fact, science as science does not have the ability or even the motive to comment on politics at all.

Format: Hardcover Vine Customer Review of Free Product ( What's this? )
Cognitive science or psychology and neuroscience really began in earnest in the 1950's. Artificial intelligence was an early throw-off of this work. Sixty years later, the discipline and sub-disciplines have come into their own. Much of the formative work for the next half-century will come from the tremendous advances underway. Here is a book that will bring you "up close and personal" into this world. Personal meaning involving you yourself.

Tali Sharot, a cognitive neuroscientist by trade, was studying the effects of trauma on memory. Her first pronouncement is that exceptionally emotional events cause us to believe that we have flawlessly accurate recollections of them -- "flash-bulb" memories as they are termed; and they are largely a sham we foist on ourselves.

The Optimism Bias is not a self-help book. It is not "The Power of Positive Thinking". It is not Sun Zu goes to Wall Street, and not pop-psychology. It is a non-technical survey of current concepts in neuroscience. Dr. Sharot does not dumb it down, rather she seats the concepts with everyday examples to give us a solid understanding of how our neural system manifests itself in our everyday thoughts and behavior. People with a scientific/medical/technical background may miss the lack of complete technical discussion. I might have taken one star if I were concerned with only their perspective. But not two stars since the tour and terminology are still solid science that I found informative and helpful. For the general intelligent reading public, I stick with five.

This book will give you knowledge of yourself and those around you to the point of actually using this information to improve your life.

Format: Hardcover Vine Customer Review of Free Product ( What's this? )
This book was like a college lecture that starts out with an exciting premise and a great first 15 minutes, but pretty soon starts to get drawn out and tiring. Tali Sharot starts the book by explaining the fascinating Optimism Bias, how the human brain seems wired into optimism. She gives countless examples of how even when presented with what should be a boring proposition like "describe a haircut", people will turn it into, "I have grown my hair for weeks so I can donate it to Locks of Love." It's just our nature.

She proceeds to discuss mental time travel and whether animals can think of a past and a future. Much of the discussion is related to how optimism developped in our brains and reasons why. As the book went on, I found myself starting to skim. It was an involuntary action, but I just could not stay with the author in her writing. Another reviewer said it felt like an article blown up to book length, and I would agree. I feel she has some great points to be made in this book, but the treatment is too long and short on solid information for the length of the book.

Worth reading or skimming once for a few key pieces of information, but I likely won't return to it.

Nothing in life is as important as when we think about it. This great aphorism is a summary on what is called the `focusing illusion'.
The book gives us many more of those. It is an easy read, a popular essay on questions of psychology, involving philosophy and evolution. I like its way of giving names, like this focusing illusion, or `defensive pessimism' (holding low expectations will protect us from disappointment --- alas, not true), or the title story: `optimism bias', a cognitive malfunction.

The optimism bias stands guard. It is in charge of keeping us healthy. Where would homsap be if we would live according to our deeper insight of futility? Optimism counteracts knowledge of death. Schopenhauer and his ilk are the enemies of mankind's future. Evolution can't handle the depressed other than by sorting them out. Depression is the inability to construct a future. Religion's place in the overall scheme of evolution is reserved in the VIP sector. Optimists live longer!

Homo sapiens' outstanding skill, compared to other species, is mental time travel, the ability to remember and to look and think ahead and make plans for contingencies. Sharot tells us that the ability to do these mental travels is located in specific brain regions. It has been observed, she says, that special brain regions in London taxi drivers shrink when they retire and don't need to keep their navigational knowledge up to speed any more. Makes me wonder if it is safe to start forgetting all the football results that I remember?
Much of the argument in the book is based on practical research, such as using brain images. Luckily I gather that the time has not yet come where a brain scanner can read your thoughts accurately.

Format: Hardcover
The Optimism Bias - A Tour of the Irrationally Positive Brain is a fun read about the neuroscience of optimism that is easily accessible to a popular audience, yet grounded in research across multiple disciplines in the social and hard sciences. In this book, author Tali Sharot presents her theory that (1) on average, people are more optimistic about their personal futures than they should be, based on the actual probability of future events, (2) this "optimism bias" has a physical basis rooted in the structure and function of the human brain, and (3) the brain's built-in tendency toward being overly optimistic has been evolutionarily selected for.

Sharot wisely anticipates that her audience will resist the notion that the human brain is pre-wired to have a flawed perception of the world. As a result, she introduces the book with objective evidence that, even when operating normally, people's brains sometimes play tricks on them. She cites examples including (1) the sometimes-fatal spatial disorientation that can be experienced by airplane pilots who lack normal visual environmental cues, and (2) certain optical illusions whose "brain tricks" can be made readily apparent to persons experiencing them. Tarot then describes various "cognitive illusions," of which she claims the optimism bias is one. It is on account of the optimism bias' status as a cognitive illusion that people typically remain unaware of, and will deny, their own excessive optimism, even while observing such a bias in others.

Sharot goes on to support her first proposition, regarding the general human tendency toward excessive optimism, with the results of psychological research.
