Indeed, participants whose answers indicated that they were high in personality traits linked to the dopamine system showed higher activity in the right substantia nigra, a part of the brain with extensive dopamine cells and receptors. Similarly, study participants whose inventory answers indicated that they were high in personality traits linked to another brain system showed higher activity in brain regions associated with that neurochemical or hormone. Lower scores in certain personality traits were found to correlate with lower activity in associated brain regions. The fMRI studies confirmed that the questionnaire scores closely matched the findings on the brain scans, accurately reflecting the brain circuitry associated with basic aspects of personality.
Dr. Fisher’s inventory has now been taken by more than 16 million people in 40 countries. While Match.com originally used Dr. Fisher’s questionnaire to create an algorithm for measuring relationship compatibility, her findings measure the degree to which the brain expresses the traits associated with each of the four systems. The neuroscience behind her research, the traits she identified, and the questions in the inventory are applicable across all human interactions—including the workplace.
