Over the last few decades, neuroscientists, psychologists and other researchers have carried out scores of studies on the mental effects of hypertext, multimedia, multitasking, interruption and distraction. The bulk of these studies point to the same conclusion: When we go online, we enter an environment that promotes cursory reading, hurried and distracted thinking and superficial learning. It’s possible to think deeply while surfing the Net, but that’s not the type of thinking the technology encourages and rewards. … We’ve begun to sacrifice other modes of thinking, particularly those that require sustained attention and concentration, which involve contemplation, reflection, introspection. … It’s altering the balance of our thought.”
According to Carr, “We can be very efficient, very productive, without those modes of thought, but as human beings we become flatter, less interesting, less intellectually distinctive and adventurous. I think as well that our ideas and our decisions tend to become narrower, more derivative, as we lose the richness of deep, idiosyncratic thought.”
