Kate Raworth explains why it's important to communicate in images: > Half of the nerve fibres in our brains are linked to our vision and, when our eyes are open, vision accounts for two-thirds of the electrical activity in the brain. It takes just 150 milliseconds for the brain to recognise an image and a mere 100 milliseconds more to attach a meaning to it. She quotes John Berger's opening lines from *Ways of Seeing*: "Seeing comes before words. The child looks and recognizes before it speaks." Another difference between words and images is where they are stored in memory. Raworth quotes Lynell Burmark: > Words are processed by our short-term memory where we can only retain about seven bits of information . . . Images, on the other hand, go directly into long-term memory where they are indelibly etched. --- Source: Raworth, Kate. _Doughnut Economics: Seven Ways to Think like a 21st Century Economist_.
