The Big Lie of the Information Age

Tor Norretranders quotes Lewis Carroll near the end of his provocative book, The User Illusion.
"That's another thing we've learned from your Nation," said Mein Herr, "map-making. But we've carried it much further than you. What do you consider the largest map that would be really useful?"
"About six inches to the mile."
""Only six inches!"exclaimed Mein Herr. "We very soon got to six yards to the mile. Then we tried a hundred yards to the mile. And then came the grandest idea of all! We actually made a map of the country, on the scale of a mile to the mile!"
"Have you used it much?" I enquired.
"It has never been spread out, yet," said Mein Herr: "the farmers objected: they said it would cover the whole country, and shut out the sunlight! So we now use the country itself, as its own map, and I assure you it does nearly as well.


Norretranders points out that the information age is actually an age with very little information. We distill so much of what happens into statistics that are supposed to be representative of a deeper reality.

Imagine that you went on a walk through an orchard. The trees are planted in a line, but each tree trunk traces its own uniquely curved path. Unseen birds sing, you watch others land in nearby branches, noting how the wings of one glisten. The sun shines a dappled pattern onto the ground, the leaves creating a random pattern of dark and light on the ground and on your skin as you walk between the trees. As you are watching this, you walk into a branch that pokes your skin, leaving a small incision, a new sore that will draw your attention throughout the next few days. You reach between the leaves and branches to find about 30 choice apples. One you discarded because it had a caterpillar. Another you discard because a bird has begun to eat it. You take these apples back to your grandfather's old juicer and run the apples through it. The smell is nearly intoxicating as the pulp is separated from the juice. You take a glass of juice from the juicer inside and share it with a friend.

That juice is not a lie. It is at best a memory of the orchard. Oddly enough, though, it becomes a memory substitute for the person who drinks it without the experience of the orchard.

So much of the modern world has become like that. Much of modern management is based on this notion that the juice is close enough to the orchard to closely represent it. Spreadsheets with numbers become a substitute for understanding a school or business, become a representation for those vastly rich and incompressible realities.

The Information Age has stripped away so much information in order to make it seem possible to represent the world with just information. Straight roads with standard width lanes have replaced meandering trails, making it possible to represent the road with lines on a paper.

It is a wonderful thing that we've learned how to represent people and places with so little information. It is a tragedy when we think that these representations, these simplifications, are an actual substitute for such people and things.

Is Consciousness Just a Trick of the Brain?

According to Tor Norretranders' fascinating book, The User Illusion: Cutting Consciousness Down to Size, your brain is tasked with an amazing responsibility. Your senses bombard it with about 11 million bits per second. Consciousness, however, can process only about 10 to 40 bits per second (estimates vary). So, the challenge of your brain is to process 11 million bits into 20 bits in way that accurately represents, or maps back to, the 11 million bits. The million+ bits flowing in from your eyes, for instance, have to be processed into familiar shapes ("Hey - that's my buddy Bill!") that shows up in consciousness as one bit rather than millions of disparate bits indicating colors, shapes, and spatial location. Cognitive processes below the surface of consciousness, processes that by definition we are unaware of, translate the millions into the few.

As it turns out, the brain takes about half a second to perform this feat - a remarkably rapid rate of calculation for processes so complex. But a half second is a really long time when it comes to awareness and sensations. This creates a challenge.

How is it that we don't seem to be going through reality with a time delay? Why aren't we aware of this half second delay? Well, for one thing, we' re only aware of what we're aware of and that is whatever is presented by consciousness . And consciousness performs an amazing feat: once it has processed the 11 million bits into the 20 bits to be comprehended by consciousness, it back dates this reality.

Let me repeat that. Tests indicate that although it takes a half second to process the sensations of reality into the perception of reality, consciousness basically tells us that it is instantaneous. It tricks us.

So, here's the real kicker. If consciousness lags reality and we don't, for instance, take a half second to decide to flex a finger or look up, what is the role of consciousness, or awareness? How is it that we interact with reality in real time even though our consciousness lags it by half a second?

It almost seems as though consciousness does less to make decisions than to trail after the cognitive processes that make such decisions - processes that are not even at the level of awareness - and explain, apologize, or rationalize what just happened. The role of consciousness may be less that of the driver of the car than that of the insurance agent who follows after the car, leaving behind claim forms in its wake.

If this is true, it raises another really important question. Who is writing my blog?
