Differences in Conservative and Liberal Brains
16 peer-reviewed studies show liberals and conservatives physiologically different
|In the 16 peer-reviewed scientific studies summarized below, researchers found that liberals and conservatives have different brain structures, different physiological responses to stimuli, and activate different neural mechanisms when confronted with similar situations. Each entry below cites the source document, and a PDF of each study has been included. The studies are arranged from most recent to oldest. We included all the peer-reviewed studies on this subject that we could find. If you know about others, please contact us with details.|
1. Conservatives spend more time looking at unpleasant images, and liberals spend more time looking at pleasant images.
|2. Reliance on quick, efficient, and "low effort" thought processes yields conservative ideologies, while effortful and deliberate reasoning yields liberal ideologies.|

4. Liberals have more tolerance to uncertainty (bigger anterior cingulate cortex), and conservatives have more sensitivity to fear (bigger right amygdala).
7. Republicans are more likely than Democrats to interpret faces as threatening and expressing dominant emotions, while Democrats show greater emotional distress and lower life satisfaction.
8. Conservatives and liberals react similarly to positive incentives, but conservatives have greater sensitivity to negative stimuli.
Fat Bastardo responds: All Conservative understand is fear and fear of losing some money.
9. Conservatives have more activity in their dorsolateral prefrontal cortices, the part of the brain that activates for complex social evaluations.
10. Conservatism is focused on preventing negative outcomes, while liberalism is focused on advancing positive outcomes.
|12. Compared to liberals, conservatives are less open to new experiences and learn better from negative stimuli than positive stimuli.|
