Walking Back the Cat

The culture of explanation

-->

Upheaval Dome is a craterlike structure in the sere desolation of Utah's Canyonlands National Park. It is a mile wide and 1,500 feet deep, and scientists are still not entirely sure how it came to be. One theory implicates the erosion of a vast underlying salt dome. Another theory invokes an otherworldly collision. Upheaval Dome certainly looks like an impact crater. A sign at its edge offers this scenario: "Some 60 million years ago, a huge meteor streaking through space ... pierced the earth's atmosphere directly above this point." The text goes on, "The meteor hit with little warning."

With little warning? Was the Hubble on the fritz? What about ground-based tracking stations? Where was CNN?

The Park Service's writers, of course, meant nothing more than "suddenly," and the wording they chose came to mind naturally. We inhabit a culture of warning, and have come to expect advance notice of nearly everything. This represents a big psychological shift. Our forebears woke up not knowing if a hurricane was about to strike. They did not anticipate fourth-quarter downturns. The threat posed by arterial plaque never entered their minds.

Today medical-imaging outlets, at shopping malls and elsewhere, offer full-body radiological scans ("the best way to show you care for those you love"); the results, preserved on compact discs, display lifelike color reconstructions of the subjects' bones and organs, with highlighted warning signs of tumors and heart disease. By regulation, restaurant menus in my state now display asterisks alongside items such as clams and sushi and soft-boiled eggs, directing customers to a cautionary footnote: "The Department of Public Health advises that eating raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of food-borne illness." Last summer the Food and Drug Administration gave its approval to the M2A Swallowable Imaging Capsule, a tiny early-warning spy satellite for the small intestine, which snaps pictures twice a second during the course of its journey. Restaurants may soon provide a bowl of these for departing patrons, next to the mints.

The forward-looking effort to spot trouble on the horizon has a counterpart in the backward-looking effort to figure out what went wrong after trouble has in fact arrived. Intelligence analysts, who often have to second-guess themselves after defections and other failures, have a phrase to describe this kind of diagnostic deconstruction: "walking back the cat." A lot of walking back the cat is being done right now, in the aftermath of the terrorist attacks in New York and Washington. But the basic procedure extends into every aspect of our lives. I won't hazard an estimate as to what percentage of GNP is allocated to walking back the cat; it clearly consumes a growing share. The study of history and cosmology is devoted to it, as is the great bulk of legal practice, much of medicine and market research, about half of geology, theology, and literature, all of psychoanalysis. Walking back the cat is what congressional investigations do. It informs the case-study approach to business-school education and lies behind the idea of the "financial autopsy." It's the whole point of watching videos of yourself at golf or tennis clinics.

An intensifying focus on "What went wrong?" is nowhere more apparent than in the proliferation of "black-box" technologies. The black box that everyone knows about is the flight-data recorder on commercial aircraft, which preserves a second-by-second record of mechanical and electronic performance. One much publicized new application is in stock cars, a consequence of the death of Dale Earnhardt during the Daytona 500 last February. Black boxes are also being installed in some passenger cars, to preserve data on speed, gas-pedal position, brake activity, force of collision, air-bag deployment, and seat-belt use. An experimental black box tested by Toyota goes even further—it has sensors capable of discerning elements of a driver's physical state, such as sobriety and cardiac condition. Rental-car companies are already installing devices that could determine if customers break company rules (for instance, by leaving the country) or drive too fast. Acme Rent-a-Car, in New Haven, fines customers $150 for every instance in which the car's speed exceeds 80 miles an hour for two minutes or longer.

Black boxes are standard equipment on trains and buses. Proposals have been advanced to put them on roller coasters and fishing boats. Although most people don't give it a moment's thought, the "History" folder in a personal computer's Web browser effectively serves as a flight-data recorder for Internet surfing. An item in the satirical newspaper The Onion once presented an interview with a psychologist who specializes in retrieving thought processes from Web browsing.

"Let's look at Christine's time online last night," said Kimble, pointing to an opened history folder on the computer screen. "She starts at the Godiva gourmet chocolates online gift catalog at 7:35 p.m. Then it's on to eDiets.com at 7:43 p.m. and the Nordic Track web site at 7:45. I'm guessing she clicked on a banner ad at eDiets to get there. Then it's on to 'Liposuction FAQs' at 7:52. Next is a page titled 'Sexy Swimwear Sale: Dare To Be Bare.' Then, at 8:06 p.m., it's back to the Godiva chocolates secure-server online order form."

Arguing that the operating room is "the cockpit of the hospital," a professor at London's Imperial College, Dr. Ara Darzi, recently proposed the installation of a black-box system for surgical procedures. Under this scheme a surveillance system would monitor traffic in and out of the operating room and record conversations; surgeons would also wear sensors on their hands to keep a record of every movement. A helpful next step, for the benefit of medical students and other observers, would be to ask the sportscaster John Madden to analyze each stage of the procedure with scrawled diagrams on the replay screen. ("Harbaugh's deep inside, trying for a triple bypass, but he's brought up short. That's an outstanding blockage.")

"DNA Fatigue" (November 1997)
Worn out by a nucleotidal wave. By Cullen Murphy

Nature has built any number of black boxes, which we've barely begun learning to use. Tree rings hold an implicit record of wet years and dry years. Ice-core samples capture a history of pollution and climate. Someday we'll learn how to open the hard drive of stored memory in the human brain. The genome is the most portentous black box of all. Mitochondrial DNA contains a record of genetic mutation going back, in effect, to Eve. Every individual's DNA harbors answers to questions that we haven't even thought to ask, though they all boil down to "What is to blame for yourself?"

Says Cullen Murphy, "At The Atlantic we try to provide a considered look at all aspects of our national life; to write, as well, about matters that are not strictly American; to emphasize the big story that lurks, untold, behind the smaller ones that do get told; and to share the conclusions of our writers with people who count."

Murphy served as The Atlantic Monthly's managing editor from 1985 until 2005, when the magazine relocated to Washington. He has written frequently for the magazine on a great variety of subjects, from religion to language to social science to such out-of-the-way matters as ventriloquism and his mother's method for pre-packaging lunches for her seven school-aged children.

Murphy's book Rubbish! (1992), which he co-authored with William Rathje, grew out of an article that was written by Rathje, edited by Murphy, and published in the December, 1989, issue of The Atlantic Monthly. In a feature about the book's success The New York Times reported that the article "was nominated for a National Magazine Award in 1990 and became a runaway hit for The Atlantic Monthly, which eventually ran off 150,000 copies of it." Murphy's second book, Just Curious, a collection of his essays that first appeared in The Atlantic Monthly and Harper's, was published in 1995. His most recent book, The Word According to Eve: Women and The Bible in Ancient Times and Our Own, was published in 1998 by Houghton Mifflin. The book grew out of Murphy's August 1993 Atlantic cover story, "Women and the Bible."

Murphy was born in New Rochelle, New York, and grew up in Greenwich, Connecticut. He was educated at Catholic schools in Greenwich and in Dublin, Ireland, and at Amherst College, from which he graduated with honors in medieval history in 1974. Murphy's first magazine job was in the paste-up department of Change, a magazine devoted to higher education. He became an editor of The Wilson Quarterly in 1977. Since the mid-1970s Murphy has written the comic strip Prince Valiant, which appears in some 350 newspapers around the world.
