In this iconoclastic book Stuart Sutherland analyses causes of irrationality and examines why we are irrational, the different kinds of irrationality, the damage it does us and the possible cure ...more

Posted on my blog.

Background: I was given this book by a friend on Christmas, and I started reading it soon afterward, but unfortunately had to stop for a couple of months and just recently finished it. This is unfortunate, since I recall a lot of things I thought about the book while I was reading it, but didn't mark any of the pages for quoting. Oh well.

Review: This book in a nutshell: humans can be very irrational at times. The book goes on to try to explore, explain and offer solutions to th

This is a catalogue of wrong thinking: inconsistency, misinterpretation, false inferences, distortion, overconfidence, conforming to the general opinion, obeying authoritative figures and making bad bets. We form instant impressions and then only look for the evidence that will support our view, we suffer from availability error, meaning that we give more weight to the dramatic and memorable, or the most recent, and ignore the less exciting evidence, and after reading the chapter on reward and p ...more

Recommended to Orestes by: Su Pezuela
This book shows a number of psychological biases during human assessment of reality which, the author claims, moves us away from taken optimal decisions. It does so by means of captivating and many times funny examples, mainly drawn from psychological experiments, but also from interesting historical events and common behavior.

The author is competent in explaining each type of irrational behavior, but the book lacks a global perspective. The instances of irrational behavior introduced in the boo

Just enjoyed, with qualifications, Stuart Sutherland's Irrationality, which I'd had sitting on my Amazon wishlist for ages and irrationally not got around to buying. It's a very enjoyable and robust exhortation to increase the rigour of our thinking, while acknowledging all the many reasons why that's extremely difficult. His enthusiasm for actuarial methods of decisionmaking is inspiring in some cases, but unconvincing in others, particularly the ones where he's forced to admit that in quite a ...more

This is the first pop science book on rationality I ever read, and it made a great impression on me. Of course, this is now more than twenty years old (the first edition dates from 1992), and probably nowadays there are many eqivalent books, but this one gives a good overview of many common pitfalls in decision making, illustrating many cognitive biases: from selective evidence, to overconfidence and ignoring or misinterpreting evidence. So you wont' get exposure to the latest developments on de ...more

I didn't realize this is a reprint of a work that is 20 years old, but it's still quite relevant. Just a little harder to get ahold of. Like most psychology books written by academics, this reads like a textbook so it's a bit of work to get through. Still, Sutherland injects a lot more wit into his writing than most, such as mentioning students who had ten grandparents with a distressing mortality rate. The material is quite good as a survey of various human tendencies to make irrational decisio ...more

I'm soooooo bored with this.
Reads like a GCSE social psychology text book.

At times like this I really wish I was so OCD that I have to finish every book I start. This one is never ending.

I've abandoned it. Really dated, and really, really boring. It now has the honour of being the first ever book I've started but not finished, and has annoyed me further by making me create a new 'abandoned' shelf on Goodreads, which clutters things up.

This book is only actually interesting if you think people act rationally more than, say, 5% of the time. Otherwise it is just a book of commonplaces backed up by a lot of studies and anecdotes you've already heard about before.

agree with one point: don't keep reading not to waste your money, at the end money won't be the only thing wasted.
one more book telling you what to do as if you did't have a brain, irrationality comes from here.

Good companion to Kahneman's "Thinking, Fast and Slow". While not much new information (for me), it was a good compilation, providing a nice structure and linking items to each other.

Ancient, published in 1992, but still interesting if not entertaining, even if much of its contents has now been rehashed in later works, though still poignantly relevant for our extensive modern online discourse, where reason is often not the primary concern.

Sutherland spends roughly half the book explaining the different types of irrationality and then uses the remainder to highlight how these work in practice.

Judging by the first thing that comes to mind is called the availability error.

Review from https://darrengoossens.wordpress.com/2017/01/18/irrationality-the-enemy-within-by-stuart-sutherland-too-true/

Penguin, 1994, 357 pages.

Well. This book is replete with summaries of studies that on the whole show that we are creatures of habit, instinct and fear more than thought and reason. We suffer from the illusion of control. We make emotional decisions and then convince ourselves they were carefully reasoned. We avoid data that might prove us wrong, even when being proved wrong is

The book summarizes studies done by others in the field in a fairly concise package. Problem is, if you read books by Kahneman, Sunstein, Thaler, Milgram, etc. there's nothing new for you to learn. Probably should be considered an intro to those books and then you can delve further into whichever piques your interest.

This book was first published in 1992, but don't let that put you off - the topics are more relevant today than ever before, particularly given the way we appear to be sliding head-first into another age of unreason. One example would be the chapter on stereotypes: very appropriate in this post 9/11 world, showing the development of prejudice towards out-groups and detailing 9 reasons why they occur - and shouldn't.

There are stacks of case studies in the book - well over a hundred, described in

Academic attempts to hit the "trade" market have made for the creation of a capacious graveyard down the years. Everyone recalls the successes without taking into account that they form way less than 1% of the attempts. This is one of the modest triumphs - an at times fascinating exploration of why people behave irrationally.

For most of the book, Sutherland is a master with the juicy anecdote, although the book sags in the middle as he abandons real world examples in favour of that boring, over

Clearly something of a classic, this book has been described as a "thinking man's self-help guide" by Ben Goldacre. It's interesting to get an expert scholarly (but not heavy) view on the various and many ways in which the human brain has irrational tendencies. Much of what is discussed should be common sense (e.g. people tend to ignore evidence that doesn't fit their beliefes) but it's backed up with discussions of psychology experiments that have been replicated and offer some proof.

A very good book examining the irrational decisions people make. It also provides methods on how best to make a rational decision and not fall into the common traps. Learning statistics and probability theory are a start.

I did find it a little boring to read at times. The writing style is a little bland and technical in nature. Also, one thing the book only touched on was why people are irrational. Is it because of the way the brain works, or is it because of our schooling, society norms or cult

Human beings are not nearly as reasonable as we think we are. Intuition, the failure to understand how probabilities work, and the curious phenomenon of "availability" (universalizing the most recent experience we can remember or alternatively the first experience, depending on whether you perceive later information as replacing or augmenting the original) all conspire to help us survive, but not to be reasonable.

Sutherland has written a satisfying little book that opens the door to being slight

The most readable and well-written popular-level book about the irrationality of humans that I have discovered. I am not a fan of the first chapter, but this is possibly because I've read a lot more of the literature on irrational behaviour and the philosophy of it, and I feel he is a little inaccurate. Furthermore, the morals at the end of each chapter could be a little less whimsical and a little more useful. The entirety of the rest of the book is excellent however, and the discussion especia ...more

This book was a extensive list of the ways in which humans are irrational. Although the advice at the end of each chapter on how to avoid these irrationality were almost simply "don't be irrational", ie if humans tend to over count X in importance the advice would be "don't over count X", the book was helpful.
While the book was written 21 years ago, it was very helpful and insightful and the editor made sure to comment on things that had changed in a footnote (but it was rarely needed).

Some interesting theories and points made, but it got a little too heavy on statistical analysis in the last third which led to me lose interest. Don't be put off by the fact the book is nearly 20 years old, it has dated very well apart from a few of the examples given.

I was particularly interested in the sections regarding why people seem to follow irrational orders and the group mentality in human behaviour. Further reading on the experiments of Stanley Milgram (Obedience to Authority) might b

I really liked this book, but somehow it wasn't an easy read. The subject matter is very interesting and it's presented in small chunks, but the language was a bit dry and boring. I am also amazed how much overlap there is between this book and Kahneman's "Thinking fast and slow" which I am currently reading also. Kahneman's book is more fun to read in terms of language and presentation but also a larger text (maybe a bit too comprehensive). There are so many common examples in these two books e ...more

Stuart has, in layman term explained some very widely mis-oriented confused belief we keep in our mind. Some of them are so common and obvious, we are doing it every moment, not even realizing it.

The best part of this book is a moral section at the end of each chapter. A very useful part, due to the vastness of statistical data and experiment done on the topic of irrationality, it is very obvious that during the whole read we forget the important take away.
Stuart does a great work by providing

this was an interesting book. fell a little short of my expectations, but was a great book still. towards the end i had to force myself a bit. the book could have done without the chapter on Utility. Starts off well, maintains its pace for quite a while and then slows down. The chapter before last, The Paranormal, was quite good again, and refers to most of the forms of irrationality mentioned in the body of the work, then it slowly winds down to an easy end. Neat. Recommend.

It's been a long time since I read this but many of the cases presented have stuck with me. A great potted summary of how we really aren't as objective as we think we are. Frankly, I think this stuff should be on every school curriculum ever. This is about more than psychological phenomena, it's really about how we make decisions and why we can't trust our unqualified instincts.

This book is a pretty good read. It really does make you think about why you do the things you do. The section on lists is quite interesting. For example - if you need to tell someone something and it's a list of information. Always put the most important thing first. It is something I would do but the explanation in the book is quite compelling.

I learned that if you want to motivate people you shouldn't give them bonuses or prize money. And that if you loose your ticket you should buy a new one. -- If it was worth buying it once, it should be worth buying it again.

All true and easy to understand. A couple of quotes from it:
"How cunning people are at twisting the evidence to suit their own beliefs."
"It is easy to manipulate the conclusions people draw from the same evidence."
