Product Description
"Steve Baker puts his finger on perhaps the most important cultural trend today: the explosion of data about every aspect of our world and the rise of applied math gurus who know how to use it." --Chris Anderson, Editor-in-Chief of Wired Magazine (Wired Magazine )
An urgent look at how a global math elite is predicting and altering our behavior -- at work, at the mall, and in bed
Every day we produce loads of data about ourselves simply by living in the modern world: we click web pages, flip channels, drive
through automatic toll booths, shop with credit cards, and make cell phone calls. Now, in one of the greatest undertakings of the twenty-first century, a savvy group of mathematicians and computer scientists is
beginning to sift through this data to dissect us and map out our next steps. Their goal? To manipulate our behavior -- what we buy, how we vote -- without our even realizing it.
In this tour de force of original reporting and analysis, journalist Stephen Baker provides us with a fascinating guide to the world we're
all entering -- and to the people controlling that world. The Numerati have infiltrated every realm of human affairs, profiling us as workers,
shoppers, patients, voters, potential terrorists -- and lovers. The implications are vast. Our privacy evaporates. Our bosses can monitor and measure our every move (then reward or punish us). Politicians can find the swing voters among us, by plunking us all into new political groupings with names like "Hearth Keepers" and "Crossing Guards." It can sound scary. But the Numerati can also work on our behalf, diagnosing an illness before we're aware of the symptoms, or even helping
us find our soul mate. Surprising, enlightening, and deeply relevant,
The Numerati shows how a powerful new endeavor -- the mathematical modeling of humanity -- will transform every aspect of our lives.
STEPHEN BAKER has written for BusinessWeek for over twenty years, covering Mexico and Latin America, the Rust Belt, European technology, and a host of other topics, including blogs, math, and nanotechnology. But he's always considered himself a foreign correspondent. This, he says, was especially useful as he met the Numerati. "While I came from the world of words, they inhabited the symbolic realms of math and computer science. This was foreign to me. My reporting became an anthropological mission." Baker has written for many publications, including the Wall Street Journal, the Los Angeles Times, and the Boston Globe. He won an Overseas Press Club Award for his portrait of the rising Mexican auto industry. He is the coauthor of blogspotting.net, featured by the New York Times as one of fifty blogs to watch.

Stephen Baker, a technology writer for Business Week, takes us into the world of data miners, forecasters, and matchmakers. The math whizzes who analyze our blogs for trends, create the ads that make us eager to buy, and analyze the chatter that could conceal signs of criminal activity--these are the Numerati. Baker gives us a chapter each on work, shopping, politics, spy vs. spy, healthcare, and even Chemistry.com. (What does the length of your ring finger have to do with the kind of person you're attracted to? Read and find out.)
Some of it is "house-of-the-future" stuff--imagine, for instance, a floor tile that will alert the doctor when your aging parent's gait seems more hesitant that usual. According to Baker, experts watching old reruns of Michael J. Fox shows can detect characteristic signs years before he was diagnosed with Parkinson's disease.
And then there's the political game. With ever-more-insightful analysis, political math mavens have found that (thank god!) America is nowhere near as polarized as you would expect. Many a liberal Democrat lurks in the McMansion suburbs, and vice versa. But politics is tough--your grocery basket doesn't lie, but nobody wants to give the time of day to a pollster. How they craft the exact political messages that will get you to the voting booth might, oddly enough, be related to your shopping habits.
Shopping--now this is a chapter that should be of interest to every die-hard Amazon fan. Sophisticated algorithms designed to deduce your taste in novels or music can be frighteningly accurate (or, as my Quick Picks occasionally remind me, maddeningly stupid, but that's the topic for a different book). After finishing this chapter, I could think of half a dozen things my grocery store knows about me that I never told them. If they chose to sell their data to magazine publishers, say, we would surely be targeted for the cooking mags ("Look, this family buys at least four units of different fresh herbs a week, and their weight in extra-virgin olive oil every month"). They can tell we have a teenager in the house ("Lots of Clean&Clear products") and could probably guess how old within a year or two ("Look it up--when did they quit buying diapers?"). Any health insurer would be interested in knowing that we spend a lot in produce and seafood, and very little at the meat counter--but what about those frequent trips to the candy aisle? It's a false positive, I swear--they're for the snack bar at my office!
You should be a little frightened, and more than a little fascinated, by The Numerati.

Great Review of A Trend, Better With Companion Reading September 10, 2008
14 out of 15 found this review helpful
I would highly recommend reading Baker's book immediately before or after reading How to Measure Anything: Finding the Value of "Intangibles" in Business by Douglas Hubbard. Baker would probably consider Hubbard one of the "numerati". Both authors talk about some of the specifics of the analysis methods (but moreso Hubbard) and both talk about the general trends and impacts (but moreso Baker).
Like his table of contents (which is simply worker, shopper, voter, blogger, terrorist, patient, lover), Baker's book is sweeping if a bit terse in places. As a quant, I find Numerati an easy read with virtually no math but still enlightening even for the most quantitatively adept reader. There were several examples in Baker's book where I already knew of the mathod but had not heard of that application. He did some great research and covered a lot of topics in this giant and elaborate field of work.
My main concern for many management-level readers of this book is that in some cases Baker gives a reader just enough information to think they can apply it to a similar problem they have, falling into the "a little knowledge is a dangerous thing" trap. Again, this can be offset with a read of Hubbard's book. It might also have been helpful to talk about the rise of "crackpot rigour" in a world with lots of data and relatively few competent mathematical analysts (various "data mining" experts come to mind).
In all, its one of my favorite reads of the year. I felt like someone was finally casting light on my own obscure field.
Not a single equation in this book September 3, 2008

I generally hate math, but The Numerati is written for people like me. It's a light journey through the data-driven world we live in and the world we will live in soon. If you think that math-generated things like amazon's "recommendations" are a cool feature of our modern world, well, you ain't seen nothin' yet. The Numerati answers some of the questions you may have wondered about and many that you hadn't thought of. All the while, you are entertained and pulled along by really great writing. For a non-fiction book, it's a page-turner. Enjoy!
They Have Your Number November 11, 2008

It may be that you have a "shopper's card" at your local grocery; you hand it to the teller as you check out, and the computer registers, besides what the total is and how the store's inventory will need to be restocked, just what the purchases were for you as a specific individual shopper. Maybe it will mail you some coupons on items it can tell you will be interested in, based on what you have already bought. Not too interesting, not too challenging for the computer, not too intrusive. But what will happen when you get a smart cart at the store? That's one that will welcome your insertion of your shopper's card, and then tell you what your shopping list usually looks like so you don't forget anything, where today's bargains are (in other words, what the store manager is trying to offload), and the fastest route through the aisles so you can get everything you need. If this sounds like it could be a useful tool for you, and also sounds a little creepy because of all the information the store (and the cart) knows about you, it's just the beginning. You may well want to see what else those who are mining your personal information are up to by reading _The Numerati_ (Houghton Mifflin) by Stephen Baker. Baker is a business journalist who wants to let us know about a new reach of mathematics into our lives. There are no equations here, just stories of the mathematicians and computer geeks that use them to find and exploit patterns of our day-to-day existence. Baker has cast some light onto many facets of an arcane realm of number crunchers, and has written a book that is entertaining and often disconcerting.
You can decide that you do not want to have a shopper's card. You can also decide that you do not want a cell phone, you never want to purchase anything on a credit card, or you do not wish to use an internet search engine. If you do volunteer for such activities, the Numerati have you. You cannot help but leave a digital trail. Most of Baker's chapters involve his looking into a particular realm of number crunching, interviewing the geeks and mathematicians who are involved, describing what has been done so far, and explaining the prospects for the not-too-distant future. Perhaps the brightest prospects for data mining are medical. Patients will do nothing extra to deliver information; it will just be monitored passively. Imagine a bed equipped with sensors that would tell how many hours we are actually spending in it, or how much tossing or turning we do, or how many times we get up for a bathroom break and how much fluid is lost on each such trip. Maybe there will be magic carpet on the floor of an elderly patient's house; it could register weight gain, or a new peculiarity in gait, or a fall, or even if the patient has stopped moving around the house during the day.
Privacy concerns are valid; it remains to be seen how much each of us will have to re-think what privacy actually means. There could also be moral questions involved; if you could make a mathematical model of a pedophile, and your church or school screens job applicants using such a model, and the screen says a candidate is an 85% fit, what is the right thing to do (and, an entirely separate question, what will be the thing to do to minimize legal liability)? And that percentage fit - it's going to be what any Numerati have to put up with, because any prediction or pattern can only indicate not reality, not truth, but mere probability. Several of the boffins interviewed here say that as complicated as are the mathematical algorithms to turn people into data, the math is the easy part; it's the humans that are hard to figure out. It is surprising, too, how simple tasks are actually monumental; terrorist watch lists of mere names present a nightmare, as any non-terrorist traveler who has a similar name will tell you. Internationalizing such data is a horrendous task; the Chinese alone, for instance, spell Osama Bin Laden eleven different ways. Baker's brightly-written and enthusiastic book presents pleasing pictures of how our numbers will come up in the future, and emphasizes those without neglecting to mention the darker issues of data misuse. He even did his own little experiment that verified something information techs have known since the most primitive of electronic computers. He and his wife filled out questionnaires at a dating site, and were dismayed that the computer did not point them in each other's direction as potential matches. It turns out that Baker had mistakenly excluded women of his wife's age. The verification: garbage in, garbage out.

Reading Baker's well-written and insightful book dispels any notion that numeracy is not necessary to fathom the 21st century.
