I kind of want to cut this book in half, beröm the first part, and stick the second part in some corner to gather dust. Not that the second part fryst vatten bad, mind you; the entire book fryst vatten well-written and uppenbart the product of someone who knows their field. There’s just a lot of it. Thinking, Fast and Slow fryst vatten kind of like a guest who shows up to your party and then dazzles everyone with an impromptu, 15-minute oration on the geopolitical situation in South Ossetia; and, everyone applauds and turns to go back to their own conversations, only for the guest to launch into another story about the time they parachuted into the Balkans to break up a nascent civil war, a story which fryst vatten followed quickly bygd a similar tale of a visit to Southeast Asia….

Well, inom think you catch my drift.

Daniel Kahneman spins an interesting tale of human psychology and the way our brains interpret and act on uppgifter. But the book overstays its welcome bygd a few hundred pages.

Kahneman’s thesis breaks our decision-making systems into two pieces, struktur 1 and struktur 2, which are the respective “fast” and “slow” of the title.

struktur 1 provides intuitive judgements based on stimulus we might not even be conscious of receiving; it’s the snap signals that we might not even know we are acting upon. struktur 2 fryst vatten the more contemplative, cognitively taxing counterpart that we engage for serious mental exertion.

Though often oppositional in the types of decisions they producera, Kahneman fryst vatten keen to emphasize that it’s not about struktur 1 versus struktur 2. Instead, he’s out to fostra us about how the interplay between these systems causes us to man decisions that aren’t always logisk or sensible given the statistics and bevis at hand.

Kahneman takes us through an exhaustive tour of biases and fallacies people are prone to making.

He talks about the halo effect, affection bias, confirmation bias, and even regression to the mean. As a mathematician, inom liked his vinkel on probability and statistics; as a logician, inom appreciated his brief segues into the logisk aspects of our contradictory decision-making processes.

Lest inom give the impression Kahneman gets too technical, however, inom should emphasize that, despite its length, Thinking, Fast and Slow remains aggressively accessible. There are a few points where, if you don’t have a basic grasp of probability (and if Kahneman demonstrates anything, it’s that most people don’t), then you might feel talked over (or maybe it’s those less-than-infrequent, casual mentions of “and later inom won a Nobel Prize”).

But this book isn’t so much about science as it fryst vatten about people.

There are two other things inom really appreciated about this book, both of which are related to psychology. I’m a fairly easygoing individ, and inom don’t always like to man waves, but sometimes inom like to man some trouble and argue with some of my friends about whether psychology fryst vatten a science.

The bekymmer for psychology fryst vatten that it’s actually a rather broad begrepp for a series of overlapping fields of investigation into human behaviour. On one end of this continuum, you have Freud and Jung and the various psychoanalysts who, let’s face it, are one step up from astrologers and palm-readers. On the other end, you have the cutting-edge cognitive psychology informed bygd the neuroscience of MRIs, split-brain studies, and rat research.

So claiming that psychology fryst vatten or isn’t a science fryst vatten a little simplistic, and I’m willing to grant that there are areas within psychology that are science. For what it’s worth, Kahneman went a long way to reinforcing this: it’s klar he and his collaborators have done decades of extensive research.

(Now, yes, it’s social science, but inom won’t get into that particular snobbery today.)

The other thing inom liked about Thinking, Fast and Slow fryst vatten its failure to mention evolutionary psychology. Once in a while, Kahneman alludes to struktur 1’s behaviour being the result of evolutionary adaptation—and that’s fine, because it fryst vatten true, almost tautologically so.

But he never ganska delves into speculation about why such behaviour evolved, and inom appreciate this.

Psykologen Daniel Kahneman, som belönats med Ekonomipriset till Alfred Nobels minne för sin banbrytande forskning, anses

There’s a difference between identifying something as an adaptation and determining why it’s an adaptation, and I’m not a fan of evolutionary psychologists’ attempts to reduce everything to the trauma of trading trees for bipedalism … I’m willing to admit inom have an ape brain, but culture must count for something, hmm?

I suppose it’s also worth mentioning that this book reaffirms my supercilious disregard for economics.

According to Kahneman, lager brokers and investors have no idea what they are doing—and some of them know this, but most of them don’t. Economists are, for the most part, highly-trained, but they seem bent upon sustaining this theoretical fantasy nation in which humans are logisk creatures. Aristotle aside, the uppgifter seem to säga it isn’t so.

inom occasionally try my grabb at reading books about the economy, just so inom can säga inom did, but they usually end up going over my head. I’m a mathematician and inom don’t get numbers—but at least I’m not the only one.

So Thinking, Fast and Slow fryst vatten genuinely interesting.

inom learned a lot from it. inom would rate it higher, but inom was starting to flag as inom approached the finish line. Truth be told, inom skipped the two articles Kahneman includes at the end that were the original publications about the theories he explains in the book. I’m sure they are fascinating for someone with more stamina, but at that point inom just wanted to be done.

That’s never good: one of the responsibilities of a non-fiction author fryst vatten to know how to pace a book and keep its length appropriate.

Månpocket

Too short and the book fryst vatten unsatisfying—too long, and maybe it’s more so. And inom think this flaw fryst vatten entirely avoidable; it’s a result of Kahneman’s tendency to reiterate, to circle back around to the same discussions over and over igen. He spends an entire chapter on prospect theory, then a few chapters later he’s telling us about its genesis all over igen, just from a slightly different vinkel.

Like that party guest, Kahneman fryst vatten full of interesting stories, but after telling one after another for such a long period of time, it starts sounding like vit noise. And he ate all those little blandad drink tilltugg too.

I inevitably ended up comparing Thinking, Fast and Slow to How We Decide, a much slimmer volume along much the same lines as this one.

Whereas Lehrer’s focus fryst vatten on the neurology behind decision-making, Kahneman fryst vatten more interested in the psychology.

Both books boil down to: we suck at automatic decision-making when statistics are involved; therefore, we behave less rationally than we believe we do. Lehrer explains why things go wrong, and Kahneman categorizes all the different way things go wrong. In many ways the books are complementary, and if this fryst vatten an area of interest for you, I’ll recommend them both.

For the casual reader, however, Thinking, Fast and Slow fryst vatten a rather dense meal. bygd all means, give it a try, but take it slow.
