A Beautiful Kluge., February 21, 2008
Customer review from the Amazon Vine™ Program (What's this?)
We'd all like to believe that we're rational and clear-headed, and that our mind, will, and emotions are reliable (except, perhaps, when it comes to romance and chocolate). However, "Kluge" indicates that our Rube Goldberg brain often doesn't work quite as optimally as we believe it does. Thankfully, Gary Marcus' mind functioned well enough to bring us this fine book.
Reading about the brain is probably the ultimate act of navel-gazing, since it's the seat of who we are, and its function determines a large part of our destiny. I was glad to see a well-done and accessible analysis of our most important organ. I found the author's breakdown of the mind enlightening, like with the relationship between memory and context. Why can't I find my clipboard? Because I put it in an unfamiliar place - duh. He also compares our faulty context-dependent memory to the more accurate and systematic way a computer accesses information. Bottom line, we come up short in the total recall department.
Mr. Marcus is firmly in the evolutionary camp, so creationists may take issue with "Kluge." Mr. Marcus believes that a patchwork brain like ours couldn't be the product of a rational, superior creator. Instead, evolution fashioned our brain based on what worked for humanity's genetic propagation, not to imitate what is perfect or holy. "Good enough for survival" was evolution's mantra, as opposed to forming an "image of God," as most creationists advocate. But the author isn't demeaning towards believers, so persons of faith can at least take comfort in that.
As the whole the book was eye-opening, with chapters on concrete themes ("Memory") and more abstract topics ("True Wisdom" - yes, there's a little cognitive self-help advice). Some of the chapters were a bit more compelling than others, but that's mainly a personal preference thing. No matter the subject, each chapter contained one or more "a-ha" moments. For example, I identified with the blinding effect pleasure has on my higher cognitive functions. I've certainly made some dumb rationalizations in order to gain immediate gratification, only to look back after the fact and ask, "What was I thinking?" Of course, I wasn't firing on all cylinders - my "grab bag of crude mechanisms" devoted to pleasure was easily tricked.
My only real gripe with "Kluge" was with the tantalizing, yet too-small bits the author threw out about certain subjects. I wish he had spent more time on, say, sociopathy. He devotes all of one sentence and a footnote to this topic, but I wanted more analysis, since the idea that brain structure might be responsible for a Hannibal Lecter would be fascinating (and somewhat ironic) reading. Indeed, a deeper dip into the link between morality and brain formation/function would have been intriguing (or perhaps disconcerting to a person of faith who believes in the theology of sin and freedom of the will). In addition, Mr. Marcus' take on the idea of changing the brain, vs. simply "doing better," would also have been welcome, since that theory seems to be in vogue these days. I suppose these topics were beyond the book's scope, so I can't complain too much.
"Kluge" is a good read on its own, but I recommend going through it in conjunction with some complementary books: "The Thing About Life is that One Day You'll be Dead," by David Shields, "Sperm Are From Men, Eggs Are From Women," by Joe Quirk, and "The Reluctant Mr. Darwin," by David Quammen.

An elegant analysis of our inelegant minds, January 26, 2008
Customer review from the Amazon Vine™ Program (What's this?)
In "Kluge," psychologist Gary Marcus looks to the many and varied foibles, inconsistencies, and inaccuracies of the human mind and concludes that our brains are not, in fact, models of brilliance and efficiency, but are rather cobbled-together systems, designed for one purpose and pressed into action for another - the classic definition of a kluge.
The most famous kluge is probably the case of the carbon scrubbers on the ill-fated Apollo 13 mission. Crunched for time, engineers managed to create a system out of duct tape and socks (seriously) that worked adequately enough to clean the air on the space module- even though none of the materials they used were designed for, or optimal for, the job at hand. The result was ugly and inefficient - but it kept the astronauts alive. Likewise, Marcus argues, evolution has endowed humans with a hodgepodge of genetic material - the DNA equivalent of duct tape - with which to build all the sophisticated systems that supposedly set us apart from other creatures, like language, memory, and reason. The result is, for example in the case of language, "a vocal apparatus more byzantine than a bagpipe made up entirely of pipe cleaners and cardboard dowels."
It's delightful metaphors like this that make "Kluge" such an entertaining read. Marcus is a talented writer as well as an insightful psychologist, and what emerges from his theory is both fascinating and well-argued. In each chapter, he looks at one aspect of the human mind whose fallacies he traces to the kluge effect. Our tendency to make irrational choices, for instance, isn't necessarily the case of a single, poorly designed system. Rather, it's caused by two separate systems in conflict - our older, more primitive hindbrain, and our evolutionarily newer, deliberate forebrain. Each system on its own is pretty good at what it's designed to do, whether reacting from instinct or reasoning through logic. It's when the multiple layers of our brains try to work together that we get breakdowns and inconsistencies - like choosing the transient pleasure of chocolate cake over the deliberate, long-term goal of losing weight.
Marcus does a great job selling his theory. I heard echoes of Bill Bryson and Matt Ridley in his conversational, often humorous writing style. It's clear that Marcus doesn't just study the human mind; he loves it for the very quirks and eccentricities that define it. His book has a clear thesis - that the kluge effect is further proof of the theory of evolution - but I wish he had done a bit more to clearly connect his thesis to the evidence he provides. Still, I understand it's a fine line to walk, and by keeping the book slim and streamlined he's made for a much better read. Anyone interested in human psychology or evolution will greatly enjoy this well-written, well-researched account of "Haphazard Construction of the Human Mind."

Accessible, Thought-provoking and Practical, March 9, 2008
Customer review from the Amazon Vine™ Program (What's this?)
Marcus has written an enormously entertaining and thought-provoking work. It is thoroughly grounded in research and a century's worth of thoughts and research about the human mind, and yet it is completely accessible and conversational in tone.
In just the first chapter he manages to refer to Shakespeare, Wallace & Gromit, MacGyver, the research of Daly and Wilson, Richard Dawkins, Bayesian theory and Aristotle. How can you not love a book that manages to get Homer, Tom Lehrer and They Might Be Giants into one sentence?
Marcus's approach is relaxed but methodical. He argues that the human mind is a kluge-- a jury-rigged whacked-together piece of work that owes more to building on what was already evolutionary present then a well-designed stab at reaching a clear-cut end (the book is a back-door argument against intelligent design, implying that if we were intelligently designed, we would not have ended up with the mess we have).
From memory, a variable mess of gaps and fabrication, we move on to belief and other mental processes that depend upon this hazy kluged-up foundation (choice, language and pleasure). Having shot holes in the idea of the brain as a marvelous machine of reason, Marcus warns of the dangers when the kluge falls apart, but thankfully does not end there, instead offering a solid list of ways to keep ourselves on a clear mental track.
Some of this work will seem familiar to those who have read "Stumbling Toward Happiness," but this is in many ways a perkier and more positive book. First, Marcus throws so many illustrations and examples at the reader that the ideas are clear and easy to understand (also leaving the reader well-armed for those dinner-party discussions about the book). At the same time, he maintains a positive tone. He doesn't consider the kluge-like nature of our brains to be reason to despair-- if we know where the pitfalls are, we can better learn to work with them instead of falling into them.
A great book, like listening to a witty, well-read, highly articulate friend report back on some fascinating stuff. Highly recommended.
