Computer simulation of dental professionals as a moral community

Area of Science:

• Medical Ethics
• Computational Social Science
• Behavioral Economics

Background:

• Current research on healthcare professionals' moral behavior relies heavily on self-reports, assuming consistent ethical dispositions.
• This approach overlooks the significant influence of peer group behavior on individual actions within professional communities.
• The interdependence of individual behavior and community norms presents a methodological challenge for traditional research.

Purpose of the Study:

• To address the methodological limitations of self-report studies in assessing healthcare professionals' moral behavior.
• To investigate the dynamics of ethical and unethical behavior within a professional community using computer simulations.
• To identify key factors influencing the prevalence of ethical conduct in a peer group setting.

Main Methods:

• Utilized a Markov replicator model implemented in an Excel spreadsheet for computer simulations.
• Modeled a dental community comprising four agent types: devious practitioners, uninvolved ethical practitioners, proactive ethical practitioners, and enforcers.
• Incorporated parameters and agent distribution criteria estimated by a panel of dental profession leaders.

Main Results:

• The simulation converged to agent type distributions closely matching the expert panel's expectations.
• The model demonstrated that the structure of moral communities is robust across various distributions.
• Reduction in unethical behavior was found to be more sensitive to interactions among ethical practitioners than to enforcement sanctions.

Conclusions:

• Computer simulations offer a viable method to study moral behavior in peer-based professional communities.
• Interactions among ethical practitioners are more critical for reducing unethical behavior than external sanctions.
• Large-scale external interventions aimed at improving professional ethics are likely to have short-lived effects.
