Testosterone, a male sex hormone, is infamous for being the aggressor behind aggression but new research shows it is also the prime respondent behind the human inclination to be antagonistic. According to a new study published in Psychoneuroendicinology, testosterone is responsible for decreasing the connectivity in regions of our brains that are accountable for feeling empathy towards others and integrating such an emotion into our decision-making processes.
A team of researchers from Utrecht University wanted to build upon prior studies that highlighted the finding that women were found to outperform men on measurable empathetic capability tests.
During the study, participants were subjected to the Reading the Mind in Eyes Tests, or (RMET). The purpose of this test was to see if the volunteer could read and determine the emotions or motives of others merely by looking at pictures of their eyes.
