Since the PG-13 rating was introduced in 1984, the rating has come to rule the box office, signalling that a movie has enough excitement to satisfy adults, but won’t leave lots of kids shaken or upset. And over those same years, PG-13 movies have also gotten more violent. New data published in the journal Pediatrics Wednesday shows that the rate of gun violence per hour in top-grossing PG-13 movies has more than doubled since 1985, and is now surpassing the rate of gun violence in R-rated movies.
Daniel Romer and his University of Pennsylvania colleagues Patrick Jamieson and Kathleen Hall Jamieson measured the level of gun violence in movies by dividing them into five-minute segments and counting how many segments included events where someone fired a weapon and hit another person. They included fictional weapons that resembled guns, such as the blasters in “Star Wars,” that can be held in characters’ hands and fire projectiles or lasers. The rate of gun violence incidents in high-grossing PG-13 movies rose from 1 per hour in 1985 to 2.63 per hour in 2015.
If a five-minute segment contained more than one such event, such as in a running gunfight, it still only counted once, though Romer said he believed that the number of shots fired in sequences involving guns seemed to be increasing.
Romer said the shift towards increasing gun violence in PG-13 movies seemed to be driven by a rise in depictions of shootings that were stylized rather than realistic.
