Yep, there are several studies researching this in various ways. An important thing to point out is that those two portions of the brains are inversely correlated without affecting other portions of the brain like the frontal cortex. So a person can be a good doctor or scientist and also be conservative. So conservatives have high fear responses to people who are different and lack empathy while left leaning people have less fear and increased empathy. Studies also show that brains develop to have an oversized amygdala when they have physical or emotional abuse as growing up or if they have severe lack of resources.
"The thigh was considered the source of posterity in the ancient world. Or, more properly, the “loins” or the testicles. The phrase “under the thigh” could be a euphemism for “on the loins.” There are two reasons why someone would take an oath in this manner: 1) Abraham had been promised a “seed” by God, and this covenantal blessing was passed on to his son and grandson. Abraham made his trusted servant swear “on the seed of Abraham” that he would find a wife for Isaac. 2) Abraham had received circumcision as the sign of the covenant (Genesis 17:10). Our custom is to swear on a Bible; the Hebrew custom was to swear on circumcision, the mark of God’s covenant. The idea of swearing on one’s loins is found in other cultures, as well. The English word testify is directly related to the word testicles."
