RATIONALITY

WHAT IT IS, WHY IT SEEMS SCARCE, WHY IT MATTERS

A reader-friendly primer in better thinking through the cultivation of that rarest of rarities: a sound argument.

Much-published psychologist Pinker looks at the not-so-common roots of common-sensical thinking.

Rationality, writes the author, “emerges from a community of reasoners who spot each other’s fallacies.” In other words, it has a social dimension, and it invites good company in order to wrestle with big problems such as climate change. Unfortunately, “among our fiercest problems today is convincing people to accept the solutions when we do find them.” That’s because so many people are so—well, irrational, or at least encumbered by bad habits of thinking and presuppositions. Discussing beliefs in ghosts and haunted houses, the author wryly points out that 5% more people believe in the latter than in the former, which means “that some people believe in houses haunted by ghosts without believing in ghosts.” Rationality is not the same thing as logic, Pinker argues, though there are points in common. Along the way, he examines the differences between propensity and probability, the maddening habit of falling victim to confirmation bias (believing what we want to believe and never mind contrary evidence), the workings of the conjunction rule (by which we conflate suppositions about people and events based on little or no factuality), and our tendency to mistake coincidence for pattern. Pinker serves up plenty of mental exercises that are intended to help us overcome the tricks our minds play on us—e.g., Prisoner’s Dilemma game-theoretic scenarios that help expose the reasons so many people are content to be “free riders” in using public goods; or stupid conspiracy theories advanced by people who believe they’re being suppressed, which, as Pinker notes, is “not the strategy you see from dissidents in undeniably repressive regimes like North Korea or Saudi Arabia.” The author can be heady and geeky, but seldom to the point that his discussions shade off into inaccessibility.

Words that made a nation.

Isaacson is known for expansive biographies of great thinkers (and Elon Musk), but here he pens a succinct, stimulating commentary on the Founding Fathers’ ode to “life, liberty, and the pursuit of happiness.” His close reading of the Declaration of Independence’s second sentence, published to mark the 250th anniversary of the document’s adoption, doesn’t downplay its “moral contradiction.” Thomas Jefferson enslaved hundreds of people yet called slavery “a cruel war against human nature” in his first draft of the Declaration. All but 15 of the document’s 56 signers owned enslaved people. While the sentence in question asserted “all men are created equal” and possess “unalienable rights,” the Founders “consciously and intentionally” excluded women, Native Americans, and enslaved people. And yet the sentence is powerful, Isaacson writes, because it names a young nation’s “aspirations.” He mounts a solid defense of what ought to be shared goals, among them economic fairness, “moral compassion,” and a willingness to compromise. “Democracy depends on this,” he writes. Isaacson is excellent when explaining how Enlightenment intellectuals abroad influenced the founders. Benjamin Franklin, one of the Declaration’s “five-person drafting committee,” stayed in David Hume’s home for a month in the early 1770s, “discussing ideas of natural rights” with the Scottish philosopher. Also strong is Isaacson’s discussion of the “edits and tweaks” made to Jefferson’s draft. As recommended by Franklin and others, the changes were substantial, leaving Jefferson “distraught.” Franklin, who emerges as the book’s hero, helped establish municipal services, founded a library, and encouraged religious diversity—the kind of civic-mindedness that we could use more of today, Isaacson reminds us.

A short, smart analysis of perhaps the most famous passage in American history reveals its potency and unfulfilled promise.

THINKING, FAST AND SLOW

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our...

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.

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our minds.
