How is it that we can recognize photos from our high school yearbook decades later, but cannot remember what we ate for breakfast yesterday? And why are we inclined to buy more cans of soup if the sign says "LIMIT 12 PER CUSTOMER" rather than "LIMIT 4 PER CUSTOMER?" In Kluge, Gary Marcus argues convincingly that our minds are not as elegantly designed as we may believe. The imperfections result from a haphazard evolutionary process that often proceeds by piling new systems on top of old onesand those systems dont always work well together. The end product is a "kluge," a clumsy, cobbled-together contraption. Taking us on a tour of the essential areas of human experiencememory, belief, decision making, language, and happinessMarcus unveils a fundamentally new way of looking at the evolution of the human mind and simultaneously sheds light on some of the most mysterious aspects of human nature.
