A month or so ago we posted on a study that appeared to show that the brains of conservative and liberals differed.
A related study has been conducted
recently by UC Berkeley.
It was looking for consistent underlying motivations to politically conservative agendas.
Four researchers who culled through 50 years of research literature about the psychology of conservatism report that at the core of political conservatism is the resistance to change and a tolerance for inequality, and that some of the common psychological factors linked to political conservatism include:
- Fear and aggression
- Dogmatism and intolerance of ambiguity
- Uncertainty avoidance
- Need for cognitive closure
- Terror management
… “[Conservatives] are more comfortable seeing and stating things in black and white in ways that would make liberals squirm,” [a lead researcher] said.He pointed as an example to a 2001 trip to Italy, where President George W. Bush was asked to explain himself. The Republican president told assembled world leaders, “I know what I believe and I believe what I believe is right.”
