Via Medium: ‘MIT neuroscientist Earl Miller notes that our brains are “not wired to multitask well… when people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost.” This constant task-switching encourages bad brain habits. When we complete a tiny task (sending an email, answering a text message, posting a tweet), we are hit with a dollop of dopamine, our reward hormone. Our brains love that dopamine, and so we’re encouraged to keep switching between small mini-tasks that give us instant gratification.’
