Foul Play - How a Slate scientist changed the NBA forever - Last week, I wrote to the NBA owner I deemed most likely to consider applying the scientific method to free-throw shooting, Mark Cuban of the Dallas Mavericks. I told Cuban that the assumption that waving balloons wildly will produce the biggest distraction is just plain wrong. Given how the brain perceives motion, randomly moving balloons aren't very off-putting. When you see a lot of little objects moving crazily back and forth, all the different motion signals that get sent to the brain cancel each other out.
