A new answer to the question of why Homo sapiens are the only species to have developed a brain with complex mental abilities.
Varki (Cellular and Molecular Medicine/Univ. of California, San Diego; co-editor: Essentials of Glycobiology, 2002) and Brower, former professor of molecular and cellular biology at the University of Arizona, shared their ideas about the origin of Homo sapiens in 2005, but Brower died in 2007 before completing his manuscript on the subject. This book is a version of Brower’s draft that Varki has adapted and expanded. They propose that when humans gained not just self-awareness but an understanding that other individuals are also self-aware and have independent minds, they thus became aware of their own mortality. The overwhelming fear that such knowledge produced would have presented an evolutionary barrier had our species not simultaneously developed a neural mechanism for denying reality. According to Varki and Brower, this convergence of self-awareness and self-delusion was a highly unlikely event that has happened only once in the evolution of life on our planet. While some other species demonstrate features of self-awareness, the authors argue that humans are unique in the mental ability to deny reality, which has led to the development of religiosity, death rituals and theories of an afterlife. Reality denial, they write, has both positive and negative consequences on the personal, societal and global level. For example, on the personal level, Varki, a practicing oncologist, cites its positive value in the experience of patients being treated for cancer; however, on the global level, he discusses the negative impact of reality denial on the issue of human-induced climate change. The final chapter presents a number of arguments likely to be offered by those unconvinced by or opposed to the theory of reality denial. A novel idea about the origins of the human mind but long-winded and repetitious in its development.

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.
The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.

Hiccups aside, a mostly valuable compendium of irrational thinking, with a handful of blanket corrective maneuvers.
A waggish, cautionary compilation of pitfalls associated with systematic cognitive errors, from novelist Dobelli.
To be human is to err, routinely and with bias. We exercise deviation from logic, writes the author, as much as, and possibly more than, we display optimal reasoning. In an effort to bring awareness to this sorry state of affairs, he has gathered here—in three-page, anecdotally saturated squibs—nearly 100 examples of muddied thinking. Many will ring familiar to readers (Dobelli’s illustrations are not startlingly original, but observant)—e.g., herd instinct and groupthink, hindsight, overconfidence, the lack of an intuitive grasp of probability or statistical reality. Others, if not new, are smartly encapsulated: social loafing, the hourly rate trap, decision fatigue, carrying on with a lost cause (the sunk-cost fallacy). Most of his points stick home: the deformation of professional thinking, of which Mark Twain said, “If your only tool is a hammer, all your problems will be nails”; multitasking is the illusion of attention with potentially dire results if you are eating a sloppy sandwich while driving on a busy street. In his quest for clarity, Dobelli mostly brings shrewdness, skepticism and wariness to bear, but he can also be opaque—e.g., shaping the details of history “into a consistent story...we speak about ‘understanding,’ but these things cannot be understood in the traditional sense. We simply build the meaning into them afterward.” Well, yes. And if we are to be wary of stories, what are we to make of his many telling anecdotes when he counsels, “Anecdotes are a particularly tricky sort of cherry picking....To rebuff an anecdote is difficult because it is a mini-story, and we know how vulnerable our brains are to those”?
