Daniel Simons's presentation of "The Monkey Business Illusion" at the Best Illusion of the Year contest in 2010. He gave the presentation while wearing a gorilla suit.

Dan Simons interviews people on the street and shows (with furry evidence) that many people have flawed intuitions about their minds.

This talk was recorded at TEDxUIUC 2010 (4/10/10), which was organized at the University of Illinois at Urbana-Champaign by a group of students led by Cristian Mitreanu.

Can people really miss a gorilla right in front of their eyes? You bet your sweet bananas they can! This video provides a tongue-in-cheek exploration of inattentional blindness with Professor Dan Simons and the often ignored Invisible Gorilla himself.
