Kang Lee, a 2014 Ig Nobel Prize* winner, asks, “Have you ever seen the face of Jesus on toast? No? … Your brain is completely normal if you see nonexistent faces in everyday objects. In fact, if you don’t, your brain may actually lack the essential ingredients for a vivid imagination.”
The research was actually mildly interesting, if unsurprising. I could not read the original article, which was published in a proprietary journal, but I found synopses here and here. The gist, at any rate, seems to have been that when observers think they see a face, even in random noise, the face-recognition area in their brain lights up.
OK, it is normal to see patterns where none exist. More-imaginative people see more patterns. Fine.
But too many people who ought to know better think that such patterns are real.
*The Ig Nobel Prizes were awarded in September, but I did not catch up with them till a broadcast on NPR the other day. Dr. Lee added, by the way, “And I have some good news for you, for those without a good imagination, I just found out, you can buy a Jesus toaster on eBay ….” You may see him at about 19 min into the tape. For the record, seeing patterns where none exist is known as pareidolia.
