It makes me wonder who these adults are. Haven't we all seen these illusions before? :roll: http://www.wired.com/wiredscience/2009/11/optical-illusion-doesnt-fool-kids/?npu=1&mbid=yhp
I saw no difference but asked DS1 to look and tell me which was bigger or were they the same size. He said one was bigger. The I explained it to him. I got a half interested "oh".
I agree, most adults should have seen these same ones over the years. I don't know if it is inpatients or more likely, people only seeing what they want to see (see political forum).
I heard Palin Beck! Its good we are posting jokes, or this needs to go into the political forum! :jester:
