Politician’s Verbal Display of Emotions Predict Violent Actions

Politician's Verbal Display of Emotions Predict Violent Actions When political leaders use oration to provoke emotions, the emotions may predict if a group will commit an act of violence or terrorism, suggests new research.

San Francisco State University researchers reviewed communications by leaders of ideologically motivated groups including activists, government and terrorist leaders.

From a study of the transcripts of the speeches delivered over the past 100 years, scientists found that leaders’ expressions of anger, contempt and disgust spiked immediately before their group committed an act of violence.

The research is reported in the journal Behavioral Sciences of Terrorism and Political Aggression.

“When leaders express a combination of anger, contempt and disgust in their speeches, it seems to be instrumental in inciting a group to act violently,” said Dr. David Matsumoto, professor of psychology at San Francisco State University.

Matsumoto and colleagues studied the transcripts of speeches delivered by the leaders of ideologically motivated groups. The analysis included such speeches as Osama bin Laden’s remarks leading up to the bombings of embassies in Kenya and Tanzania.

The researchers analyzed the pattern of emotions conveyed when leaders spoke about their rival group and examined speeches given at three points in time before a specific act of aggression.

They compared the results with the content of speeches delivered by leaders whose groups engaged in nonviolent acts of resistance such as rallies and protests.

Among leaders of groups that committed aggressive acts, there was a significant increase in expressions of anger, contempt and disgust from 3 to 6 months prior to the group committing an act of violence. For nonviolent groups, expressions of anger, contempt and disgust decreased from 3 to 6 months prior to the group staging an act of peaceful resistance.

Matsumoto says the findings suggest a leader’s emotional tone may cause the rest of the group to share those emotions, which then motivates the group to take part in violent actions.

“For groups that committed acts of violence, there seemed to be this saturation of anger, contempt and disgust. That combination seems to be a recipe for hatred that leads to violence,” Matsumoto said.

Anger, contempt and disgust may be particularly important drivers of violent behavior because they are often expressed in response to moral violations, said Matsumoto, and when an individual feels these emotions about a person or group, they often feel that their opponent is unchangeable and inherently bad.

“Understanding the preceding factors that lead to terrorist attacks and violent events may help predict these incidents or prevent them occurring in the first place,” Matsumoto said. “Studying the emotions expressed by leaders is just one piece of the puzzle but it could be a helpful predictor of terrorist attacks.”
