5.0 de un máximo de 5 estrellas No somos tan listos como nos creemos… 14 de octubre de 2013
Por Ignatius
Formato:Tapa blanda|Compra verificada por Amazon
Vaya por delante que odio los libros de autoayuda, por si alguien cree que este libro este encaja en la categoría al uso. Afortunadamente, nada que ver. Este es, en esencia, un libro de psicología, que trata sobre el funcionamiento de nuestro cerebro. Sin embargo, tampoco es un libro técnico, o académico, pese a que está muy bien documentado.

Cada capítulo se dedica a derribar cada uno de los mitos y creencias que tenemos sobre nosotros mismos en lo que respecta a nuestra racionalidad, y nuestra forma de pensar. Te demostrará que no eres tan listo como crees,… siempre que seas lo suficientemente listo para darte cuenta.

El libro está lleno de anécdotas y experimentos contrastados, todo narrado con mucha ironía, y con un estilo muy directo. El nivel de inglés es accesible. Muy recomendable.

5.0 de un máximo de 5 estrellas Brilliant, entertaining and useful 15 de noviembre de 2011
Por Timothy Miller - Publicado en Amazon.com
Formato:Tapa dura|Compra verificada por Amazon
I'm a clinical psychologist interested in neuroscience, so much of this material was already familiar to me. Most of the ideas can be found scattered through other books like The Winner's Curse, The Happiness Hypothesis, Predictably Irrational, and others. I've read and admired all of those. I would gladly throw them all away if I could keep You are Not So Smart.

The author understands the science and the facts, and conveys them quite clearly. I didn't find a single error. He writes wonderfully. Crisp, clear, funny, casual, but not too casual. When I read it, I feel I'm chatting with a brilliant buddy. As I understand it, the author is not a professor or scientist. He's certainly smart enough to be one.

In the 1970s and early 1980s, research psychologists generally believed that humans are more or less rational, most of the time. They believed that irrational thinking was caused primarily by disruptive emotions like anger or fear. We now know this is just plain wrong. During the last twenty years or so, research evidence against this view accumulated. Daniel Kahneman became the first psychologist to earn a Nobel Prize for describing the new understanding.

Meanwhile, evolutionary psychology provided a new template for understanding the human mind. It evolved. We often see faces in clouds, but never see clouds in faces. We sometimes mistake a coiled garden hose or rope for a snake, but rarely mistake a snake for a garden hose. These tendencies, and many others like it, reflect our evolutionary history. The reproductive cost of jumping away from a coiled garden hose is very small. The reproductive cost of failing to recognize a dangerous snake is very high.

You do not think rationally, nor does anyone else. This is useful information, particularly if you have some understanding of how and why you -- and others -- think irrationally, and under what circumstances. It may seem too good to be true, but this book actually explains it to you, and does so entertainingly.

Even today, most economists believe that humans make rational economic choices. This is clearly false. Daniel Kahneman (and his collaborator, Amos Tversky) won their Nobel Prize, not in psychology -- there's no Nobel Prize category for that, but in economics. You ever wonder how we got stuck in this awful Great Recession, despite the brilliant insights of modern economists? It's because they are all wrong. This book will help you understand that better, while making you smile, laugh and nod your head with "Aha!" insights along the way.

Many psychotherapists believe, even today, that Sigmund Freud and his intellectual descendants correctly described "the unconscious." They believe that our childhood experiences, particularly psychosexual experiences, form the emotional and behavioral templates for the rest of our lives. We now know that most mental life is indeed unconscious. However, the templates of our mental lives were formed more by our common evolutionary history than our particular childhood experiences. That's why cognitive biases are human universals. If idiosyncratic childhood experience was the more important source of thinking templates, the cognitive biases described in You are Not So Smart would not be so robust and numerous.

You want to know yourself? Spending your life contemplating your potty training might help a little... or might not help at all. This book will help a whole lot more.

If you want to know yourself, start by studying your blind spots. Oops. Too bad. You can't find them with introspection because they are... blind spots! Good news, your blind spots are the same as other people's blind spots. They are human universals. So you can learn about them by studying all the recent scientific discoveries about human thinking, particularly all its irrational and unconscious features. The universal, irrational and unconscious landscape of human thinking is the topic of this book.

I previously described two well-known and rather obvious features -- faces in clouds versus clouds in faces and snakes versus garden hoses. This is very useful information.

Clouds vs faces: All humans have an "agency detection bias. We presume that things happen for reasons and that most things happen because an intelligent agent made them happen. Hence, ummm... Oh, I remember... Religion??!! Knowing this, next time a natural disaster occurs in a sinful city, you might be a little less inclined to attribute the event to an angry god. You might also recall that all cities are sinful.

Snakes vs. garden hoses: All humans have a hyper-sensitive immediate-danger-detector. The vast majority of alarms are false alarms. Not many citizens of industrialized nations die of snake bite, but many die or suffer from excessive worry and pointless fears. Understanding how false danger alarms work, you might be more able to live long and prosper.

Please excuse the irony. As I recall, the author does not actually discuss agency detection or danger detection bias. These are merely convenient examples of universally human cognitive biases that occurred to me was I was writing this review. They are easy to explain and intuitively obvious. You are Not So Smart discusses forty-eight others. He's chosen many of the really important and interesting phenomena. The list grows as research accumulates, and he probably didn't have room for all of them. Good news, he publishes periodic updates on his blog.

This book has a high speed to weight ratio. Every chapter describes a universal human cognitive bias, easily recognizable in your own experience. Chapters are just a few pages each. They do not need to be read in sequence. Though not simplistic, a smart eight grader could understand most of them; no scientific or psychological background is necessary. Yet these phenomena are not generally known, even by "smart" people. Thanks to this book, word will soon be getting around.

4.0 de un máximo de 5 estrellas Broad Overview of Cognitive Biases, Shortcuts, and Fallacies 27 de octubre de 2011
Por Book Fanatic - Publicado en Amazon.com
Formato:Tapa dura
This is a good book. It's easy to read and can be read in small bite-sized chunks or in several long sessions. There are 48 different cognitive biases, shortcuts, and logical fallacies described in the book. They each take about 5 pages or so. Within each section the author does an excellent job of describing each problem. He references several studies for each and is generally very up-to-date on the latest work.

As an introduction or description to the ways we are irrational this book works very well. I consider myself pretty widely read in this area and still I found some new ideas or studies in this work. I would think that someone new to the topic would be utterly fascinated by it. While this book is well written as narrative it also would server as an excellent reference because of the many short chapters.

The only thing that I think would have made the book better would have been to put more effort into highlighting how you can avoid the biases. Certainly being aware of them helps and this book goes a long way toward that goal. The author does make some small suggestions at the very end of many chapters but they seem like an afterthought. But that is my only real criticism.

If you are interested in the ways that we aren't "the rational animal" this book is easily recommended. It is quite well done. For people new to the subject I can very highly recommend it as an introduction to the topic.

3.0 de un máximo de 5 estrellas accessible but maybe too much so 17 de octubre de 2012
Por Michael J. Amos - Publicado en Amazon.com
Formato:Tapa dura
McRaney is attempting to show us all that behind the thin veneer of our civilized brain, lurks an animal brain that is far more whimsical and powerful than we give it credit for, than our logical brain often does little more than make excuses for behavior it can't predict or control. He does so by examining a variety of behaviors from cold reading to brand loyalty to racism. He conducts his examination be compiling peer reviewed articles from psychology and medical literature.

I give McRaney credit for making the material accessible but I can't say the same about making it interesting. It's incredibly, painfully obvious that the book is little more than a collection of blog posts; the short chapters don't quite run two pages while long ones clock in around ten. Additionally, I feel like the concepts he covers are already in the public eye, available for more complete examination and occasional satire. Finally the author does nothing with the information. No tips for catching yourself in a behavior are suggested, it seems he simply acknowledges the behaviors with an indifferent shrug. I could accept this if McRaney was doing some amount of original work or thought but that's not the case.

The way I most often described this book as I read it was "It's not bad, it's not good, but it's not bad."

ADDENDUM: I later read Thinking, Fast and Slowand recommend that as a far superior book on similar material.

5.0 de un máximo de 5 estrellas A book everyone should ready to just TRY to get a little bit smarter 31 de octubre de 2011
Por Guido A. Sanchez - Publicado en Amazon.com
Formato:Tapa dura|Compra verificada por Amazon
This book is one that you will breeze through quickly, and after nearly every page, want to tell every single person you know what you have learned. The citations of numerous psychology studies that really reveal an enormous amount about the way we think, why we think, and how we think, are illuminating, and I feel just a wee bit smarter by reading this book. In fact, I sincerely believe the world would be a much more incredible place if everyone in it read this book.

4.0 de un máximo de 5 estrellas A gem of a book that any reader should find fascinating 31 de diciembre de 2011
Por M. E. Taylor - Publicado en Amazon.com
Formato:Tapa dura
Not a five-star book, no. But so close! The chapters detailing scientific studies from neurologists and behavioral psychologists are, for this humanities guy, the meat of the book, and they make the book one I would recommend to anyone.
A weakness: long about the middle of the book, we get several chapters rehearsing the logical fallacies of rhetoric (things like the ad hominem argument, or the bias for false authorities), and these are much less interesting, less compelling, and certainly less fresh than what comes before or after. Perhaps without them, the book would have seemed too short, but they nearly derailed the book for me.
Another minor beef I had was that you can, at times, sense the author bending or massaging his data or his analysis to make subtle insinuations about whose politics are smart and whose politics are not. It becomes more overt near the end, and while I am certainly not outraged or offended that someone wants to suggest that smart politics tend to fall with one party and not the other, it wasn't the kind of move I tend to appreciate. (On the other hand, his interpretation of politics may flatter some readers, and they may like the book even better for that very reason... though wouldn't that itself be a cognitive bias?)
Also, I think too often, to make his point, the author makes it seem as if a bias in one direction equals a kind of knee-jerk determinism to act a certain way under certain conditions. That is to say, if people tend to do something under certain test conditions, the author extrapolates that they will pretty much always act that way in the real world. I was often reminded of the notion in Quantum Theory that observation affects reality. I'm not confident, in other words, that the way people behave in behavioral experiments at universities is identical to the way they behave when they aren't being observed, tested, asked to perform to produce data. A more honest approach might be to acknowledge that a tendency is just that, but hardly determinative or binding.
Yet to be fair, that would make the book a bit more timid and dull than it aspires to be. I kind of like the way that McRaney makes it all so vivid and clear. The subtlety the book lacks would make it all a bit more gray. I also love his sense of humor. Humor often relies on eliding nuances, so I am willing to forgive a lack of qualification to make room for a good joke.
This is the kind of book that I found myself constantly reading passages from to the wife (poor thing). It's almost always surprising and delightful.
