The Serotonin-Driven “Builders”

The suite of traits associated with specific activities and genes in the serotonin system include sociability, caution (harm avoidance), less anxiety and more close friends. Elevated activity in the serotonin systems is also linked with observing social norms, following the rules, respecting authority, orderliness, adherence to plans, methods and habits, self-control, precision, interest in details, conscientiousness, figural and numeric creativity, and religiosity. So Helen Fisher called this trait constellation the ‘cautious/social norm compliant’ and dubbed them “Builders”.
