Far-right and far-left brains react similarly to political content.

People with strong political beliefs, whether liberal or conservative, process political content similarly at a neurological level.

Why it matters

  • Shows that extreme political views may be tied to stronger emotional reactions.
  • Supports the "horseshoe theory", suggesting that political extremes may resemble each other more than they do moderates.
  • Could help reduce hostility and increase understanding across the political divide.

By the numbers

  • 44 participants across the political spectrum.
  • Brain scans showed increased activity in areas associated with emotion and threat detection.
  • Extreme individuals showed more synchronized brain responses.

The big picture

  • Emotional reactions play a central role in ideological extremity.
  • Extreme individuals process political content in similar ways, regardless of ideology.
  • Findings suggest a shared neurological experience among political extremes.

What they're saying

  • Some skepticism about methodology and definitions.
  • Concerns about controlling for trauma and disinformation.

Caveats

  • Small sample size.
  • Limited to specific political topics (immigration and policing).
  • Conducted only in the United States.

What’s next

  • Further research to explore different political subjects and cultural contexts.
  • Investigate how emotional processing might differ between moderates and extremes.
