Final answer:
A study on biology and aggression would probably indicate that people with higher neuroticism levels show more aggression. Yet, the relationship is complex, with research indicating that cultural and social factors substantially shape aggressive behaviors.
Step-by-step explanation:
For a study concerning biology and aggression, one is likely to find that people who have higher levels of neuroticism or quite possibly high levels of testosterone could show higher levels of aggression. However, research such as Fausto-Sterling's points towards complexities in proving a straightforward relationship between testosterone and aggression.
Cultural influences and social factors also play significant roles in shaping aggressive behavior, according to anthropologist Carol Ember's findings in Kenya. And, of relevance is the finding that pro-social behaviors are more common in populations, which might imply that aggression is often an objection to perceived threats to an individual or their in-group, shaped significantly by cultural norms.Moreover, a consistent theme across these aspects is that aggression is not solely derived from biology but is a complex interplay of internal factors such as personality traits, external influences like cultural pressures, and situational stressors.
