If everything fades into the background, you may have a high IQ

I have no idea if this study has any weight at all but I do know that I have a high degree of focus. When I was a kid I would focus so deeply sometimes my dad had to physically shake me to get my attention.<p>Never had my IQ tested though so no idea if I exhibit the correlation or not.

This link includes the video that was used on the participants. You can see and check your own IQ.<p><a href="http://www.businessinsider.com/iq-video-test-university-of-rochester-2013-5" rel="nofollow">http://www.businessinsider.com/iq-video-test-university-of-r...</a>

I don't understand how they justify the leap from visual size to "background information."

I can't focus. Must be retarded.

how many times does it have to be repeated? correlation doesn't imply causation!

Sounds like a nice candidate for a web app, should they release how exactly it's done.
