Pitfalls of counterfactual thinking in medical practice: preventing errors by using more functional reference points

Area of Science:

• Cognitive Psychology
• Medical Education
• Decision Science

Background:

• Counterfactual thinking involves simulating alternatives to reality, impacting medical decision-making.
• While often beneficial, counterfactual thinking may have dysfunctional consequences in medical practice.
• This study investigates if medical experience influences counterfactual thinking to improve decision quality.

Purpose of the Study:

• To examine if practicing physicians learn from experience in a decision-making task.
• To determine the extent to which counterfactual thinking impedes learning in medical professionals.
• To assess the generalizability of prior findings on counterfactual thinking to physicians.

Main Methods:

• Ten practicing physicians completed 60 trials of a computerized Monty Hall Problem simulation.
• Learning was operationalized by measuring the frequency of switch-decisions.
• This builds on prior research with undergraduate students using a similar decision paradigm.

Main Results:

• Physicians showed some learning, with an overall increase in switch-decision frequency.
• However, the extent of learning was not ideal or practical.
• Participants selected the optimal decision strategy in only 50% of trials despite feedback.

Conclusions:

• Physicians demonstrated a failure to learn basic decision-outcome associations through experience.
• Counterfactual thinking appears to be a primary inhibitor of learning decision-outcome associations in this sample.
• Findings suggest professional experience may not enhance medical decision-making quality, necessitating future research on alternative reference points.
