Dan Simons, the University of Illinois Professor of Psychology, is renowned for his work into inattentional blindness (failing to see obvious but unexpected events). His 1999 ‘Gorillas in our midst’ paper with Christopher Chabris is now legendary. In October 2011, Simons explained how a parapsychologist named Tony Cornell (pictured) was responsible for the first study of inattentional blindness. Cornell’s work took place in the late 1950s, and involved white sheets and the Cambridge University Society for Research in Parapsychology. Find out more on Simons’ blog post, here.
