A new study identifies brain circuits that regulate how intensely people engage with politics, without altering their beliefs. Researchers from Northwestern University and Shirley Ryan AbilityLab show that the prefrontal cortex and amygdala influence political fervor rather than ideology. The findings could guide efforts to promote calmer public dialogue and improve neuropsychiatric assessments by revealing the neurological roots of political passion.

In a study involving Vietnam War veterans with various brain injuries, researchers found that damage to the prefrontal cortex heightened political intensity by reducing cognitive control. In contrast, lesions to the amygdala tended to lessen fervor by dampening emotional responses. The team notes these circuits affect political engagement across the ideological spectrum, reinforcing that intensity—not content—is shaped by brain activity. Thai readers will appreciate how this research speaks to everyday debates that can become emotionally charged, underscoring the value of emotional awareness in discussions.

A new study links lower self-awareness to stronger brain responses when people encounter morally charged political issues. Published research shows that moral judgments engage emotion and cognitive-control networks, helping explain why some political beliefs feel non-negotiable.

In today’s highly polarized climate, the findings matter for Thai audiences as well. The study, led by a senior researcher from a major university, examines how moral conviction shapes political choice. It finds that people with moralized views decide more quickly and rely more on emotional brain processes. This pattern is strongest among individuals with limited metacognitive sensitivity—the ability to judge one’s own judgments accurately.
