There's a lot of research that indicates the brain rewards us for multi-tasking by giving us a shot of neurochemicals whenever we start a new task. Our brain rewards us even as our performance in every task degrades. We don't even notice that our performance is bad. We don't care. We feel like masters of the universe because our brain is chemically rewarding us for multi-tasking.
