Jonah Lehrer:
And this is why we should all follow strangers on Twitter. We naturally lead manicured lives, so that our favorite blogs and writers and friends all look and think and sound a lot like us. (While waiting in line for my cappuccino this weekend, I was ready to punch myself in the face, as I realized that everyone in line was wearing the exact same uniform: artfully frayed jeans, quirky printed t-shirts, flannel shirts, messy hair, etc. And we were all staring at the same gadget, and probably reading the same damn website. In other words, our pose of idiosyncratic uniqueness was a big charade. Self-loathing alert!) While this strategy might make life a bit more comfortable – strangers can say such strange things – it also means that our cliches of free-association get reinforced. We start thinking in ever more constricted ways.
Neat.
