The influence of surgeon personality factors on risk tolerance: a pilot study.

OBJECTIVE: This study attempts to assess the association between surgeon personality factors (measured by the Myers-Briggs Type Indicator personality inventory (MBTI(®))) and risk tolerance (measured by the Revised Physicians' Reactions to Uncertainty (PRU) and Physician Risk Attitude (PRA) scales).

DESIGN: Instrument assessing surgeon personality profile (MBTI) and 2 questionnaires measuring surgeon risk tolerance and risk aversion (PRU and PRA).

SETTING: Saint Raphael campus of Yale New Haven Hospital in New Haven, Connecticut.

PARTICIPANTS: Twenty categorical surgery residents and 7 surgical core faculty members.

RESULTS: The following findings suggest there might be a relationship between surgeon personality factors and risk tolerance.

CONCLUSIONS: In certain areas of risk assessment, it appears that surgeons with personality factors E (Extravert), T (Thinking), and P (Perception) demonstrated higher tolerance for risk. Conversely, as MBTI(®) dichotomies are complementary, surgeons with personality factors I (Introvert), F (Feeling), and J (Judgment) suggest risk aversion on these same measures. These findings are supported by at least 2 studies outside medicine demonstrating that personality factors E, N, T, and P are associated with risk taking. This preliminary research project represents an initial step in exploring what may be considered a fundamental component in a "successful" surgical personality.
