Psychology September 16 Lecture 5
Current political debates may be caused by how individuals respond to change. Change can be
perceived as threatening or as an opportunity.
Hypothesis: differences in DNA diff. in response to change diff. in political attitude
Political attitudes may vary with physiological traits
Case study: Twins and political attitudes
- Identical twins showed similar political attitudes despite being raised in different
households (different environments) while fraternal twins had a greater difference in
political attitudes, suggesting that political attitudes are biologically based.
There are established connections between:
- DNA and response to stressors
- Response to stressors and political attitudes, thus providing evidence that left/right
political differences reflect response to threat and may have a genetic basis.
