It is all just numbers

kw: book reviews, nonfiction, mathematics, computer science, social trends

Do you sit in front of a computer at work? At least part of the time? It is possible, though still a bit clumsy, for your company to track your work habits. If, as I do, you are in a "managed desktop" environment, there could be an app running in the background that logs your activity. While the times of "no activity" may reflect several kinds of "break"—think time, a pit stop, getting a snack or drink, a phone call or colleague's visit—the ratio of active/inactive is just the first ratio a logging program will produce. Perhaps the program also notes time spent in MS Word, Excel, your e-Mailer, surfing with Firefox (and the search terms you enter). Today's PCs have sufficient power to obsessively gather every click and keystroke and when they occurred, while running your applications, seemingly without noticeable impact.

Now consider: if you wear an RFID-tagged badge all day, as I do, it is possible to track your movements about the facility. The PC you are currently not typing at may not "know" why, but a building system could determine whether you really are in the restroom, break room, hallway, or in front of the screen (reading this), and prehaps if the phone is in use. The tag readers that I use to enter my building need the tag to be waved within six inches (15 cm). Who knows whether more capable readers are located throughout the building? I don't. One thing is sure: someday they will be.

Life gets easier once you get home. Off goes the badge. For most of us, the TV doesn't watch us back. But there are test being conducted, particularly for the sake of the elderly, of weight-measuring floor tiles, motion sensors with full-house coverage, perhaps widgets attached to refrigerator, stove and microwave, recording personal habits. When those habits change, or there is a sudden change in weight or in level of activity, someone can be alerted to see how the "subject" is doing. For many frail folk, this could be a godsend. At what point in your life would it go from being "they know too much" to "I need it"?

These are a few instances in which numerical modeling of data being continually gathered is gaining impact in our lives. How soon will it be that the grocery cart in your favorite market will recognize you and show you a route on a GPS-enabled screen, optimizing the route you need to take to fulfill your shopping list—and it already knows what your usual shopping list contains. You could tell it three extra items, and a new route will reflect your new list. It may also lead you past a display or two, calculated to entice you to make an impulse purchase that accords with your (known) tastes. How many people would run screaming from that store, looking for a Mom-N-Pop grocery with "dumb" carts? How many of their children would accept it without even a shrug? Give it time.

In his new book The Numerati, Stephen Baker makes these and other points, though a little less starkly, among his interviews with many of the leaders of the many efforts to turn everything that happens into data, and crunch that data on stacks of supercomputers. When will it be that there is a stack of numbers somewhere, that comprises a mathematical model of Polymath07, knowing my tastes and proclivities, my favorite color (and favorite vice), my favorite everything, my political tastes (or lack thereof), the kinds of people I prefer to be with, my favorite kinds of reading material (a summary of this blog will comprise that part), and whether I prefer having a cat or a dog (I'll never tell; let them find out), or both? What do I collect? Do I have house plants? What kinds? Do I mow my own lawn or hire someone? (Ha! You found out I have a lawn!!).

There was a time that "efficiency experts" such as Frank Gilbreth (of Cheaper by the Dozen) walked around the factory floor with clipboards, optimizing each worker's routines. We will soon be outnumbered by our virtual efficiency experts. Is that a good thing? After chapters showing what the Numerati are working on, in the realms of the workplace, the home, the hospital, the voting booth, national security, even dating services, Baker begins to tell us, Learn to use the numbers for yourself.

We won't all be mathematicians. But we do have some control. Don't like your bank selling your data? How about selling it yourself? From page 205:
One nonprofit organization founded in 2005, AttentionTrust, … provides Web surfers with the tools to amass their own data and sell if, if they choose, to advertisers.
Does that sound like a good idea? It may be. I looked for the organization, but the links are all dead. They may be defunct already. If they are, someone else will probably try soon. What else could one do?

It is hard to say. To date, most people have relied on "security by obscurity." Be ordinary, do ordinary stuff, don't get noticed, and you'll be ignored. Now that the computer power exists to crunch through all the data we all generate, all the time, that is less possible. An idea I like? Be just a little bit subversive. Do you have a "loyalty card" at the supermarket (or several – I carry five)? Get a second one at the same market. Use a variation of your name. Shop differently when you're using the alternate card. Use a different credit card, or cash. When the smart cart arrives, go ahead and follow its path. Then take some of the paths not taken; see what specials are being offered in the other aisles. Think: what does the grocer want from me? Shift your buying pattern to inject confusion into the process. You can extend such ideas into many areas of life.

You may find that adding some randomness and serendipity into your routines will make life more fun! Data-analysis routines are designed to figure out your predictable behaviors. Be less predictable. A side note: In my lifetime, I have taken training classes in several martial arts. The best advice I got was from Joe Begala, the author of the Army's 1940s "hand-to-hand combat" training material. He taught a "Self Defense" class at my college in the 1960s. He said, "If you have to fight, don't stand in any particular way. I can tell if a guy knows Karate, or Aikido, or Boxing, by the way he stands. Then I know something about him. I don't want him to know that about me." I can say this, his class should have been titled "Applied Street Fighting".

Will our grandchildren live in a world not just measured, but controlled, by the Numerati? The Numerati will try. It is up to all of us to keep them off balance.
