Preparing health professionals to respond to misinformation: an inoculation theory approach

Abstract

Health professionals are increasingly expected to address misinformation after patients encounter it, but health-professions education should also prepare them to anticipate misleading claims and influence strategies before those claims shape patients’ beliefs and decisions. Inoculation theory offers a useful framework for that preparation. Modeled after biological inoculation, the theory explains how preexposure to weakened persuasive challenges or misleading techniques can build resistance to later influence. Although inoculation has a long history in health communication, it has received far less attention as curricular content in health-professions education. This commentary argues that future health professionals should learn inoculation theory itself as part of their communication training. It outlines a basic curricular primer centered on threat and preexposure, introduces technique-based and issue-based approaches, and offers sample messages instructors could use to teach each. It also considers more applied activities, including analysis of existing inoculation games, message design, role-playing, and hypothetical cases. Teaching inoculation theory could help future practitioners recognize likely influence challenges and construct preemptive responses for use in professional practice.
