wiki֊ոտ գիրք ա էլի։ էն որ լիքը անկապ պատմութիւններ, լիքը էստեղից էնտեղից օրինակներ։ դէ, ոնց հիմնականում լինում են լաւ վաճառուող/կարդացուող(?) գրքերը։

Audio book #2 - so far, the intro was interesting.
Easy to read (listen to) - good combo of scientific info and stories.

Lehrer's "How We Decide" is yet another book on the apparently quite popular topic of understanding how we make decisions. Having already read Gladwell's "Blink" and Brafman's "Sway", like many reviewers, I did notice a lot of overlap. However, I thought Jonah's more scientific approach to the topic was enough to make it well worth the read.
For example, Gladwell mentions the Univeristy of Iowa study where participants played a gambling game with 4 decks of cards (two of which end up being far more likely to yield positive results). He explains that the participants brains recognized the pattern before the participants themselves were aware of it. Lehrer, however, tells you *why* those participants brains picked up on the patterns.
In the end, I'd recommend this book to anyone interested in neuroscience. Even if you've read some of the other popular books, you'll still find value in Lehrer's more scientific, yet still approachable, discussion of the topic.

This book was very taxing to read since it took me forever to get through and my brain kept shouting, "NO!" at every scientific inconsistency.
Writing style wise, the book is captivating. Lehrer uses lots of stories to connect the psychological ideas with real-life. He's a great storyteller. It's easy to read and very entertaining. I would've rated this book higher if it wasn't for his bad science. If you're not a big science person and would just like to enlighten yourself about decision-making, this may be a good book for you.
Now, to explain the taxing of the book and my brain's reaction. I'm a psychology major, so I know many of the concepts that Lehrer is talking about. My brain just wants to facepalm itself every time he introduces a new idea. He takes an idea and then stretches it beyond its max, such that the idea is no longer valid. Let's take the submarine example. The man chose to signal an alert even though the enemy missile looked the same as an ally ship. Why? Lehrer claims it's his emotions. The truth is, it's the connections in his brain that has formed overtime from practice-and not emotions-that allow the man to make the right decision. Yes, it's mostly unconscious, but the fact is it's not an emotional decision. It's because of connections that have been established through past experiences.
Let's take another example: chapter 7 "The Brain is an Argument." In this, Lehrer basically describes what social psychologists call the Confirmation Bias, but he never calls it that. It's a phenomenon due to the way the brain is structured and not an emotional response. Emotions may be a symptom of Confirmation Bias, but it's not the reason why people always support what they think is right. Many psychologists think that people use Confirmation Bias to increase their confidence and increase their confidence of their level of survival since theoretically you're more likely to survive if you're not experiencing a threat.
What's funnier is that Lehrer says what every good scientist says, "Correlation does not equal causation," yet he takes correlations and makes them into causation to support his ideas. He's using the Confirmation Bias, not emotional reasoning.
I'm not sure what his definition of emotion is. It's not clearly defined. He quotes it as physiological symptoms (sweating, heartrate), as neurotransmitters (dopamine), and as neural structures in the brain (amygdala), as intuition or just some "feeling". He doesn't fully explain how all of these aspects are connected, basically just claiming that we're unconscious of it all. However, we can explain a good bit of our emotions (we know failing a task will make us feel miserable), so I don't think all of his claims are valid. The biggest problem with this book is that most of the research he quotes is still under investigation. We don't know enough about the unconscious and intuition to be able to say, "Yes, this is how emotions work." There are so many variables in humans that science hasn't been able to clearly classify emotions with strict definitions. To say that we can decide everything with "feelings" is preposterous because that word could mean so many different things. Sometimes, these "feelings" aren't just feelings, but our brains making connections that we aren't thinking about because we're not practicing meta-cognition (thinking about our thinking).
To sum up his book in a more scientific way, we make decisions using experience from past events (connections between neurons formed due to learning and practice), meta-cognition, and neurotransmitters activating certain regions in our brains. None of these things fully explain emotions unless you think emotions are all biological and have no other components. However, emotions and decisions are more complex than what he claims.

Entertaining journalist's reporting/lit review on the psychological research in decision-making. Vividly written, engaging.

Sometimes I run into a grocery store with the intent to purchase one thing and then I take 10 minutes making a decision about the benefits of one choice over the other. It is a waste of time, but also why do I feel the need to think about this so much? On the other hand some big decisions are a lot easier for me. How We Decide is a really fun and interesting look in decision making and how the human mind works. This is a definite must read for any one interested in decision making and/or the human brain.
