Sayeth David Carr:
What changes our brains is, on the one hand, repetition and, on the other hand, neglect. That’s why I believe the Net is having such far-reaching intellectual consequences. When we’re online, we tend to perform the same physical and mental actions over and over again, at a high rate of speed and in a state of perpetual distractedness. The more we go through those motions, the more we train ourselves to be skimmers and scanners and surfers. But the Net provides no opportunity or encouragement for more placid, attentive thought. What we’re losing, through neglect, is our capacity for contemplation, introspection, reflection — all those ways of thinking that require attentiveness and deep concentration.
Granted, graduate students of all types are often forced into being “skimmers and scanners” but they are graduate students…research is central their raison d’etre, whereas for undergrads…not so much. And while certain sites do encourage attentive thought, I suspect that the groupthink will outweigh the introspection and contemplation for which Carr longs. Hence people will be seeking out their suppositions, rather than actually slog through the process of learning. The Internet magnifies the potential for dumb aggregation of information, not the coherent synthesis of it.
