Researchers then showed violent and non-violent images to study participants – one in each eye – who were then told to indicate on which one they focused. While doing so, participants wore headphones and listened to either the death metal band, "Bloodbath," or the song "Happy." The goal was to measure how much participants' brains noticed violent scenes, and to compare how their sensitivity was affected by the accompanying music, said lead researcher Yanan Sun.
The findings were that everyone, including death metal fans, were affected by the violent images being presented to them, according to The Independent.
“This finding raises doubts about arguments that long-term exposure to violent media may desensitize consumers to violence,” the scientists wrote.
When Bloodbath’s lead singer, Nick Holmes, was asked how the band felt about their music being used in the study, Holmes said they didn’t mind.
“The majority of death metal fans are intelligent, thoughtful people who just have a passion for the music," he said. "It's the equivalent of people who are obsessed with horror movies or even battle re-enactments."
