If you thought that life was weird, well, it got a little weirder now.

Key to All Optical Illusions Discovered | LiveScience

Here is the scoop:

"When light hits your retina, about one-tenth of a second goes by before the brain translates the signal into a visual perception of the world."

Freaky! The proposed answer is even stranger:

"...it's our visual system that has evolved to compensate for neural delays, generating images of what will occur one-tenth of a second into the future. That foresight keeps our view of the world in the present."

Ever wondered why planning for the future is so hard? Maybe our corporate perception systems do not make up for the fact that there is a substantial delay between the world/market/competitor changing and us noticing. Maybe the price for such a "foresight", the potential for illusions, is rather low, compared to the other option of constantly steering looking through the rear-view mirror... Andy Groves might have been right when he said "Only the Paranoid survive": seeing things that are not (yet) there is powerful stuff!
