A lucid account of brain research, our current knowledge, and problems yet to be solved.
A fresh history and tour d’ horizon of “the most complex object in the known universe.”
Although scientists still struggle to understand the brain, they know a great deal about it; Cobb, a professor of biological sciences, delivers an excellent overview. No one experiences his or her brain, but even the ancients were conscious of their heart, so deep thinkers, led by Aristotle, concluded that it governed human actions, perceptions, and emotions. Some Greeks experimented—on live animals; Cobb’s descriptions are not for the squeamish—but “they merely showed that the brain was complicated. Aristotle’s heart-centered view remained enormously influential, partly because of his immense prestige but above all because it corresponded to everyday experience.” Matters changed only with the scientific revolution, and Cobb writes a riveting account of four centuries of brain research that soon revealed its structure and made slower but steady progress describing its functions, which depend on complex brain cells, neurons, that communicate with each other through electrical signals but don’t actually touch. The author ends the “history” section and begins “present” in the mid-20th century. This may puzzle readers, but he has a point. “Since the 1950s,” he writes, “our ideas have been dominated by concepts that surged from biology into computing—feedback loops, information, codes and computation, but…some of the most brilliant and influential theoretical intuitions about how nervous systems might ‘compute’ have turned out to be completely wrong.” Although the computer metaphor is showing its age, the digital revolution has produced dazzling progress, allowing scientists to study individual neurons, localize brain activity in living subjects, and manipulate objects by thinking. Cobb concludes that this avalanche of new knowledge hasn’t brought us nearer the holy grail of brain research—a neural correlate of consciousness—or led to dramatic advances in treating mental illness or paralysis, but these will happen…eventually.

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”?
