But in this, we pursue an illusion. When we think we are multitasking, our brains are actually moving quickly from one thing to the next, and our performance degrades for each new task we add to the mix. Multitasking gives us a neurochemical high so we think we are doing better and better when actually we are doing worse and worse. We’ve seen that not only do multitaskers have trouble deciding how to organize their time, but over time, they “forget” how to read human emotions.
