Katy Perry Accused of Using "Psychological Warfare" on 'Idol' Contestants.
Katy Perry, judge on American Idol, has been criticized for tricking contestants into believing they were eliminated before revealing they were moving on to the next round. Social media watchdogs are comparing her bait-and-switch tease to “psychological warfare” on the initially crestfallen contestants. Perry has been a constant source of controversy this season due to her allegedly harsh comments toward contestants. The formative success of the singing competition hinged on original judge Simon Cowell’s infamously blunt critiques. “American Idol” airs Sundays at 8 p.m. Eastern on ABC.
