A new neuroscience study this week used MRIs of human test subjects taken while they looked at artworks, some real some fake, and found that our brains respond differently to the forged and genuine articles even when they initially appeared indistinguishable. (Try telling that to the guy who bought the $17 million fake Jackson Pollock.)
The study just published in the journal Frontiers in Human Neuroscience, the Telegraph reports, found that when test subjects were told that the artwork they were looking at was the real deal "it raised activity in the part of the brain that deals with rewarding events, such as tasting pleasant food or winning a gamble." On the other hand, when an artwork was revealed to be a fake, "they tried to work out why the experts regarded it as such."
Thus, Professor Martin Kemp, Emeritus Professor of the History of Art at Oxford University, one of the experiment's conductors, concludes:
It is always better to think we are seeing the genuine article. Our study shows that the way we view art is not rational, that even when we cannot distinguish between two works, the knowledge that one was painted by a renowned artist makes us respond to it very differently.
The moral here is that all art is real, even when it's forged.
