AFTER THOUGHT

THE COMPUTER CHALLENGE TO HUMAN INTELLIGENCE

Computer-aided math is now at a point where unaided human intelligence cannot follow the proofs, a fact that has profound implications for future science, according to James (a former executive at Thinking Machines Corp.). He illustrates this thesis by summarizing the role of different forms of math in the history of science and philosophy. Ptolemy constructed his astronomical theory on a geometrical basis of perfect circles. But when astronomers (notably Tycho Brahe) began to collect data that failed to fit the theory, new mathematical tools became necessary to construct a more accurate model of the cosmos: first algebra, then calculus. Descartes's step-by-step sequential method was matched to the strengths of the human mind and gained its most impressive results from a miserly amount of data. But physical scientists came to scorn ``mere'' data collection. A true scientist worked to discover abstract theoretical principles; collecting data and doing arithmetic were the jobs of assistants. The earliest computers mimicked the methods of human calculators; their main advantages were increased speed and almost perfect accuracy. Advanced computers change all that, handling incredible floods of data with ridiculous ease—and in many cases, in parallel streams. It is no longer unthinkable to simply pile up huge quantities of fact and analyze the resulting patterns. The implications of this are most profound in disciplines to which the sequential maths were least adaptable: meteorology, biology, and economics, all of which generate enormous masses of seemingly chaotic data. The computers can analyze these data and discover patterns, even though the programmers can no longer follow their ``reasoning.'' What this finally means is that we humans will increasingly have to accept computers as equal partners in the enterprise of science—and to accept as valid computer-generated results we cannot begin to understand. A fascinating tour of scientific history, concluding with a vision of a future that is at once exhilarating and profoundly unsettling.

I AM OZZY

An autobiography as toxic and addictive as any drug its author has ever ingested.

The legendary booze-addled metal rocker turned reality-TV star comes clean in his tell-all autobiography.

Although brought up in the bleak British factory town of Aston, John “Ozzy” Osbourne’s tragicomic rags-to-riches tale is somehow quintessentially American. It’s an epic dream/nightmare that takes him from Winson Green prison in 1966 to a presidential dinner with George W. Bush in 2004. Tracing his adult life from petty thief and slaughterhouse worker to rock star, Osbourne’s first-person slang-and-expletive-driven style comes off like he’s casually relating his story while knocking back pints at the pub. “What you read here,” he writes, “is what dribbled out of the jelly I call my brain when I asked it for my life story.” During the late 1960s his transformation from inept shoplifter to notorious Black Sabbath frontman was unlikely enough. In fact, the band got its first paying gigs by waiting outside concert venues hoping the regularly scheduled act wouldn’t show. After a few years, Osbourne and his bandmates were touring America and becoming millionaires from their riff-heavy doom music. As expected, with success came personal excess and inevitable alienation from the other members of the group. But as a solo performer, Osbourne’s predilection for guns, drink, drugs, near-death experiences, cruelty to animals and relieving himself in public soon became the stuff of legend. His most infamous exploits—biting the head off a bat and accidentally urinating on the Alamo—are addressed, but they seem tame compared to other dark moments of his checkered past: nearly killing his wife Sharon during an alcohol-induced blackout, waking up after a bender in the middle of a busy highway, burning down his backyard, etc. Osbourne is confessional to a fault, jeopardizing his demonic-rocker reputation with glib remarks about his love for Paul McCartney and Robin Williams. The most distinguishing feature of the book is the staggering chapter-by-chapter accumulation of drunken mishaps, bodily dysfunctions and drug-induced mayhem over a 40-plus-year career—a résumé of anti-social atrocities comparable to any of rock ’n’ roll’s most reckless outlaws.

An autobiography as toxic and addictive as any drug its author has ever ingested.

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.
