Wired article on perceptual bias in tennis line calls.
Tennis players should be disputing more referees calls that their shots landed outside the lines, according to a new study by brain researchers.
About 100 milliseconds of lag time built into the human visual processing system causes observers to systematically misperceive how far objects have traveled. In tennis terms, that perceptual bias leads referees to incorrectly call shots out that actually hit the line.
