Brain Bugs

How the Brain’s Flaws Shape Our Lives

De: Dean Buonomano

Narrado por: William Hughes

A lively, surprising tour of our mental glitches and how they arise.

With its trillions of connections, the human brain is more beautiful and complex than anything we could ever build, but it’s far from perfect: our memory is unreliable; we can’t multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but. Drawing on striking examples and fascinating studies, neuroscientist Dean Buonomano illuminates the causes and consequences of these “bugs” in terms of the brain’s innermost workings and their evolutionary purposes. He then goes one step further, examining how our brains function—and malfunction—in the digital, predator-free, information-saturated, special-effects-addled world that we have built for ourselves. Along the way, Brain Bugs gives us the tools to hone our cognitive strengths while recognizing our inherent weaknesses.

Reseñas de la Crítica

“Intriguing take on behavioral economics, marketing, and human foibles.” ( Kirkus Reviews)

Thoroughly reinforces material from my classes.

The author did a thorough gathering of the discrepancies embedded in the processing functions of the human brain.

Fun, Not Perfect

This was a fun read/listen, if you’re into fun pop science books you’ll probably enjoy it. I was frustrated that the reasoning and source material seem to fall down a bit once the book gets to religion. The author quotes Hutchins and Dawkins but not Geertz, which I see as a red flag. From there it goes downhill with all sorts of assumptions about religion in culture being taken for granted without the necessary foundation of religious anthropology. So, if that’s an area you know a bit about, maybe skip that chapter to avoid yelling at the narrator repeatedly!

An informative and well balanced book

As a regular person (non academic) I could follow this book 100% I like his use of examples. A fascinating journey into the human mind.

Engaging tour of the highlights of neuroscience

This book investigates structural and procedural aspects of thought, imposed as evolutionary solutions to selection pressures. Problems with memory, both accuracy and quantity, problems making accurate judgements of time, problems with disproportionate and distorting influence of fear, and problems with reasoning in which our intuitions conflict with what we can establish to be true by more rigorous statistical thinking are areas which are discussed. The neurobiologic mechanism underlying these problem areas is laid out and then the "bugs" which follow from the evolutionary solutions are examined.

An example of the difficulties which arise in the attempt to use the brain for thinking rationally is rooted in the use of association for understanding the deluge of data each brain is presented with on a daily basis. Association works well to correlate a red color with a poisonous plant, less well to serve our own interests when it associates promise of sexual fulfillment with a cigarette brand, a make of car, a perfume fragrance, or a particular type of underwear, as a result of some advertisement. The book examines how these faults are capitalized on by advertisers and purveyors of political propaganda in order to sell us goods or to capture our vote.

A chapter on the human propensity to believe in supernatural causes provides thought provoking associations between the fallacies to which the brain is prone based on its neural hardware and beliefs in supernatural entities. By reading other reviews of this book, it is clear that a large number of people don't want this particular box opened and peered into. In all fairness, the data in this regard is far from conclusive. Moreover, Buonomano paints with a pretty broad brush in parts of this chapter, making several arguments which will only appeal to those who already agree with his viewpoint. On the other hand, he reviews several scientific hypotheses for why belief in a deity is such a common feature of human society.

Science is based on examining evidence and determining causal or likely correlations within this data. Ideally this is followed by testing an hypothesis in an experimental setting in which confounding variables are controlled for, thus allowing for a test of correlation or causation. As the belief in the presence of a god is based on faith, it falls outside of the realm of what can be investigated by methods of science. One question science can ask is why, in absence of compelling evidence for a God or gods in the external world, does this belief so commonly exist in human brains. Several thought provoking hypotheses are reviewed. Unfortunately, creating a controlled experiment to test these hypotheses is difficult to come by, short of creating an experimental earth complete with craggy fjords overseen by hyperintelligent pandimensional beings with the manifestation, in the human dimension, of mice.

A weakness of the book is the short chapter at the end of the book on avoiding the inherent limitations of the brain. Essentially he recommends scepticism and common sense. Fair enough as far as that goes, but one could expect a little more directed and helpful analysis.

This is my main criticism of this book: its lack of a more cohesive, comprehensive argument, particularly in the last two chapters. But that is not the aim. This is a quick, engaging, easily digested examination of the highlights of neuroscience and applications to areas pertinent to daily life, and in that regard it is successful.

Interesting, though a little political at times

I love the material presented in this book; the details about how the brain works down to the level of neurons was fascinating. My only complaint is that the author sometimes got too political. For example: implying that supporting certain presidential candidates is considered a "brain bug". Even if I may happen to agree with you on those particular candidates, there is no need for that kind of stuff in a book like this. All it does is cheapen the otherwise very compelling arguments.

Ironically, for an author who seems to abhor religion, his political remarks make him sound downright preachy.

Still a worthwhile listen, but it could have been so much better.
