Politicians who use violent rhetoric are driving greater polarization

October 26, 2017

Scroll through Twitter or watch an NFL game and you'll quickly remember we live in a time of unprecedented political polarization. Who's to blame for the lack of unity? According to BYU and LSU researchers, politicians' penchant for using violent language isn't helping.

"Even if it's metaphorical, and everyone knows it, there's something that happens when you frame things in terms of battle or war that has real-world consequences," said BYU professor Josh Gubler.

Recent research by Gubler, fellow BYU professor David Wood and LSU professor Nathan Kalmoe reveals that when politicians use words like "fight" or "battle" instead of "work" and "struggle," they excite their own bases, but also polarize those on the other side of the political divide.

For their study, recently published in the journal Political Communication, the researchers had Republicans and Democrats read political statements on policy issues, then measured their support for these policies. Some subjects read statements with words like "fight" or "battle" while others read statements with synonyms like "effort" and "work."

Gubler, Wood and Kalmoe found the common violent metaphors actively drove aggressive partisans further apart on issues, resulting in a polarization effect of 20 percent, despite such a subtle shift in language.

"Many partisans are pushed to see politics as war today, rallying to their party's platform when cued with violent metaphors," Wood said. "You might get your base more excited, but you might be less likely to get anything done because the other side is also moving farther away from what you want."

So how are politicians supposed to excite their bases without pushing the other side away?

Kalmoe suggests a process called micro-targeting, which is a narrower way to send messages to registered voters. An example of this would be sending an email campaign to certain voters as opposed to a television ad that everyone can see.

"If you can restrict your use of that language or the reception of that language to people that are just on your side, then you have the ability to push in one direction on political issues," Kalmoe said.

While politicians use this language frequently, they aren't entirely to blame. The media, according to the research team, are as well.

"This language also appears in a lot of news coverage because journalists find it useful to play up the conflict," Kalmoe said. "Even when it's just meant to try to spice up their story, it could have some negative consequences for the political process."

While violent metaphors mainly affect those who have naturally more aggressive personalities, the team sees this discovery helping everyone be more unified.

"If we can help citizens understand how they're influenced, they can be more deliberative, thoughtful, and careful in their political rhetoric in talking with friends and family, and working at the local and national level of politics," said Wood.
