Against (some) slow-motion replay

This Slate story discusses the work of Zach Burns, a psychologist in the business school at Northwestern, who argues against using slow-motion replay to judge intent in sports, such as for fine-worthy hits, flagrant fouls, etc. Slowing something down affects perception, makes it appear that the built-up to the conduct, and makes viewers more likely to find that someone acted with evil intent. Burns does say that replay is fine for judging actions, such as whether someone crossed a line, although it seems to me we'll likely see the same skewing of perception.
