We've all had experiences of our attention wandering, usually at those moments when we most need to concentrate. But, in our productivity-driven society, are we placing too much emphasis on paying attention and failing to recognise the benefits of more unstructured thought processes? After all, focus comes at a cost. With numerous demands on our attention, it's all too easy to experience burnout. Unfocus can recharge our batteries and allow us to be creative by making connections and connecting with other people. In this episode, Aleks Krotoski explores some of the different modes of attention we can switch between and asks whether, perhaps, we should be awarding our unfocus equal status to our focus.
