"Inattentional blindness"


It's a special type of "blindness" that 's explained below the fold.  First, look at the picture and count the number of red circles you see.

Are there five red balls - or six?

Now - look away from the photo and describe to someone exactly what you saw.  Most people fail at this.


What you saw (in addition to the five red balls) was "a real photo of the hands of Cuban man Yoandri Hernandez Garrido, who has polydactyly, which means he has extra digits on his hands (he also has an extra toe on each foot.)... This is called "inattentional blindness", where we can't see what's right in front of us because we're not paying attention to it."
