A study published in Nature found that testosterone actually encourages fair behaviors if it serves to ensure one's own status. The hormone increases sensitivity for status, leading to pro-social behavior in humans, rather than aggression. This challenges the long-held assumption that testosterone causes aggressive behavior.
A study of 3,128 mothers found that increased TV exposure in young children is associated with aggressive behavior. Household TV use also contributed to the risk, suggesting a link between parental environment and childhood aggression.
A recent study found that a person's facial width-to-height ratio can be used to predict their tendency towards aggression. Volunteers rated the aggressiveness of male faces and found high correlation between the rating and the face's WHR, suggesting that subtle differences in face shape may affect personality judgments.
Researchers found that individual wasps benefit from being recognizable, as they are less likely to be targeted in aggressive encounters. This finding suggests that diversity may promote group stability, extending beyond wasp societies to potentially influence human facial variation and social interactions.
