Studies that accuse social networks of reducing productivity assume that time spent microblogging is time strictly wasted. But that betrays an ignorance of the creative process. Humans weren’t designed to maintain a constant focus on assigned tasks. We need periodic breaks to relieve our conscious minds of the pressure to perform — pressure that can lock us into a single mode of thinking. Musing about something else for a while can clear away the mental detritus, letting us see an issue through fresh eyes, a process that creativity researchers call incubation.
