Effective medical diagnosis depends not just on looking, but on truly perceiving. Recognizing this, many medical training programs have adopted Visual Thinking Strategies (VTS) discussions about art to enhance students’ skills in nuanced observation, inference, and communication. In 2004, Harvard Medical School pioneered use of VTS within medical education to refine the diagnostic and interpersonal skills of future healthcare professionals. Now, VTS is embraced in over 30 medical schools.
