New York: Individuals with a higher level of moral reasoning skills have an increased gray matter in the brain, reveals a study. The new study adds an investigation of individual differences in moral reasoning to the expanding landscape of moral neuroscience.The team employed MBA students in the age group 24 to 33, past the age at which structural brain maturation is complete and were tested for their moral reasoning.


Students then underwent MRI scanning to investigate differences in gray matter volume between students who reached the post-conventional level of moral reasoning compared to those who have not reached that level yet. Subjects also underwent personality testing and were placed into one of the following categories: neuroticism, extraversion, openness to experience, conscientiousness and agreeableness.


Analysis showed higher scores in openness to experience and lower scores in neuroticism for participants at the more advanced levels of moral development.
