A well-informed tour of a mysterious and crucial part of the brain, promising greater self-awareness and mental clarity.
A professor of neuroscience and psychology delivers a wide-ranging study of how memories make us who and what we are.
Memory is a quirky thing, writes Ranganath, director of the Dynamic Memory Lab at the University of California, Davis. We can remember song lyrics from 20 years ago, but we can also forget what we ate yesterday. The author has been trying to understand memory for decades, and he admits that a huge amount still remains a puzzle. He explains the mechanisms of memory in the brain and the different types and levels of memory, as well as the evolutionary reasons for it. Many theories have been posed about how memories develop, but the current thinking involves “a phenomenon called error-driven learning,” where memory is a constant process of reworking experiences to fit our larger mental picture. Memory failures have been linked to depression, poor sleep, and other ailments. Ranganath explains how fake “memories” can be inserted by repeated suggestion, to the point that people have “remembered” and confessed to crimes they didn’t commit. Some memories, especially those of traumatic events, break into our consciousness unbidden. The author suggests that they can be kept under control by persistent and intentional rejection, although it takes effort. He also offers tips on how to not forget routine things (phone, keys) by connecting their image to something else. It’s useful advice, but much of the book is devoted to Ranganath’s examination of theories of memory and the new generation of testing. Anyone expecting a simple how-to guide on improving their memory may be disappointed. The author’s research is undeniably intriguing, but the book will appeal to specialists more than general readers.

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”?

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.
