Fast Balls: Bad Calls!

http://www.macroevolution.net/fast-balls.html

A recent study performed by David Whitney of the department of Psychology at the University of California Davis. His study challenged tennis referees in their dicissions on whether a ball is in or out. In his research he discovered that the human brain estimates a bad trajectory when it comes to tennis because the tennis ball makes an unpredictable path. Thus the brain sees the ball over the line rather than on it.

In my opinion, I think the research is for the better because it shows (to tennis players) that it might be benificial to challenge something that they think is wrong. But in a way I disagree that humans can not correctly percieve where the ball is going. Because in soccer the ball is moving pretty fast and I predict, most of the time, the correct trajectory and are able to have a good touch on the ball. But for tennis players, this reseach will be benificial to their game.
