Harvard researchers have now shown that even medics suffer from ‘Invisible Gorilla Syndrome’. Although you might not think it, radiologists are just human and not superheroes who sit in a darkened room all day picking up every minor deviation from the norm. Trafton Drew, a researcher at Harvard Medical School’s Visual Attention Lab, showed radiologists images like the one below and asked them to identify cancerous nodules… Click to enlarge The Results expand(document.getElementById('ddet1678059509'));expand(document.getElementById('ddetlink1678059509')) 83% missed the gorilla waving his fist in the image.
