What Is the Fisher Temperament Inventory?

The Fisher Temperament Inventory (FTI) was developed by anthropologist Dr. Helen Fisher. It is based on the idea that personality is deeply influenced by four neurochemical systems in the brain. Everyone is a blend of all four, but the relative activity of each system shapes your unique temperament profile.

Four Temperament Types

Type Neurotransmitter Description
🚀 Explorer Dopamine Curious, energetic, spontaneous. Drawn to novelty, risk-taking, and creative pursuits.
🏛️ Builder Serotonin Calm, cautious, conventional. Values loyalty, order, tradition, and careful planning.
🎯 Director Testosterone Analytical, decisive, tough-minded. Excels at logical reasoning, systems thinking, and direct communication.
🤝 Negotiator Estrogen/Oxytocin Empathetic, imaginative, intuitive. Strong emotional depth, vivid imagination, and deep interpersonal sensitivity.

Scientific Basis

The FTI originates from Fisher et al.'s 2013 study published in PLoS ONE ("Neural Correlates of Four Broad Temperament Dimensions") and has been cross-validated with the Big Five. Multiple fMRI studies have confirmed correlations between FTI scores and specific brain activity patterns.

How It Helps

Knowing your temperament type helps you understand why you show certain patterns in decision-making, social behavior, and relationships.
