I read the abstract of the referenced article, this entire image is Conservative nonsense. The study did not find that liberals had an "atrophied" amygdala. It showed that conservatives have an enlarged right amygdala, due to their overpreparedness for a fear response.Meanwhile, the study found that liberal had a larger anterior cingulate cortex, which is an area of the brain commonly associated with empathy and other higher-order processes like decision-making.
The study provides support for conservatives being scared piss babies who are overly terrified of the world, whereas liberals are empathetic and make better decisions. The fact that this idiot made the entirely wrong conclusion is almost as incredible as it is sad.
