Berlin: A new neuroscience study has explored how the human brain processes rigid or extreme belief systems, revealing a direct link between fanaticism and impaired cognitive control.
The research, conducted by a team of neuroscientists, has found that individuals exhibiting fanatical traits show reduced activation in the brain’s dorsal anterior cingulate cortex (dACC), a region essential for self-regulation and decision-making.
The findings suggest that when cognitive control is weakened, individuals may become more susceptible to ideological rigidity, emotional reasoning, and resistance to evidence that challenges their beliefs.
This aligns with prior research connecting the dACC to functions such as error monitoring, conflict detection, and adaptive learning, processes that enable humans to reconsider or adjust opinions when presented with new information.
The researchers stated that the participants displayed clear signs of diminished self-regulation and an increased tendency toward polarized thinking, consistent with the reduced dACC activation observed during the study. They noted that understanding fanaticism through a neurological lens provides insights into how deep-seated convictions can override rational judgment and empathy.
The study further emphasized that investigating fanaticism is not only a scientific pursuit but also a public health concern. By identifying the neurological patterns underlying extreme thinking, societies can better design educational and psychological interventions that promote critical thinking and emotional balance from an early age.
One of the lead researchers stated that this approach represents a ‘developmentally informed prevention strategy’ that can protect public well-being and strengthen democratic cohesion.
The authors concluded that understanding how fanaticism emerges in the brain is crucial to fostering tolerance, open-mindedness, and social harmony in an increasingly polarized world.
