>>14429965iq is a naturally evolved phenomenon, static images are don't occur in nature. naturally developed pattern recognition isn't geared towards static images, in a real world situation only the highest IQ's would briefly see the illusory pattern and the recognition would be either ignored or not quite worked out all the way once it was recognized as fallacious, the whole sequence would happen in an instant and subconsciously, the high IQ mind wouldn't notice it happen. the high IQ brain would go to all that trouble just to notice the dog half a second before you do.
the static image allows the illusion, a brief trick of light and shadow, to be concentrated on, so lower IQs can noice it.
