Changes

Chronic state of conservatism is chartrised characterized by small smaller anterior cingulate cortex ([[ACC]]) and hyperactive enlarged amygdala<ref>[http://amodiolab.org/wp-content/uploads/2012/03/Jost-Amodio-2012.pdf Jost, J., & Amodio, D. (2012). Political ideology as motivated social cognition: Behavioral and neuroscientific evidence. Motiv Emot, 36, 55–64.]</ref>. The ACC is used to control efforts and also rostral ACC is active in learning intuitively social behaviors. if having small volume of the ACC, people will react more impulsively, and will have difficulty to understand social interactions. This will cause them to perceive unfamiliar people with less understanding and therefore with more mistrust.
