This multi-institutional study supports the research hypothesis: students’ exposure to the humanities is linked to important personal qualities and prevention of burnout. The qualities we measured are neither part of the admissions process nor regularly tested during standardized board examinations, and yet they may affect both patient satisfaction and outcome,30 as well as cost and quality of care.31, 32 Hence, this study may carry implications for both admission standards and professional development.
Our survey suffered from a few limitations, including recall and reporting biases, plus a relatively low return rate, not uncommon in survey-driven designs,33 especially one like ours that required significant time. Additionally, removing participants who failed to complete at least 80% of the survey further reduced responses from 912 to 739. We did not attempt to measure whether censored responses would have made a significant impact, and of course a low response rate might have invited selection bias. Yet our return was still close to 24%, which is nearly double the average of 10–15% for external surveys. Furthermore, by conducting the study at multiple locations, we increased our response representativeness, which has been cited as being more important than the actual response rate.34 Lastly, the observational nature of our cohort study identifies only correlations, not causation. Further studies in which exposure to the humanities serves as intervention would be needed to better clarify their role.
Nevertheless, our results suggest that the humanities do correlate with important physician qualities. Of interest, the three personal qualities that correlated most strongly with exposure to the humanities were tolerance of ambiguity, empathy, and wisdom. This is intuitive considering that the humanities are not only a way to teach compassion and tolerance, but also represent the wisdom of those who came before us. In fact, wisdom might very well be the single trait that encompasses all of those other traits which define a well-rounded doctor: empathy, openness to possibilities, emotional resilience, mindfulness, humility, altruism, a knack for learning from life, plus a cathartic sense of humor. However, wisdom is not a focus of today’s medical education, which concentrates primarily on information and knowledge. Ironically, knowledge without wisdom might be dangerous.35 As Socrates put it in Menexenus, “all knowledge, when separated from justice and virtue, is seen to be cunning, and not wisdom.”36
Forty years ago, bioethicist Edmund Pellegrino suggested that well-rounded physicians share three main characteristics: competence, compassion, and education.37 Few would disagree with the need for competence and compassion, but the issue of “education”—in Pellegrino’s description, a “liberal arts” education, i.e. culture—has received much less attention. Yet, it is the one ingredient whose presence was considered fundamental until the 1910 Flexner report. Writing in 1902 about the “four great features of [our] guild,“38 Osler described medicine as the profession of a “cultivated” person. Flexner himself included in his 346-page report an often forgotten passage where he mentioned the “varied and enlarging cultural experience” he considered so important to the education of physicians.39 More recently, Lewis Thomas8 and Sherwin Nuland40 urged a return to the humanities as the ideal repository of the moral and cultural knowledge required of physicians. However, being “cultivated” is no longer a tenet of the profession.
In fact, humanistic fields are often spoken of as though they were a waste of time. But as was reported to Congress by Richard H. Brodhead, the president of Duke University and co-chair of the Commission on the Humanities & Social Sciences, “this facile negativism forgets that many of the country’s most successful and creative people had exactly this kind of education.”41, 42 Others have echoed his opinion,43, 44 and business leaders like Google prioritize applicants with a liberal arts education.45 The humanities may even foster a different way of seeing, thinking, and feeling,46 that can then be used in any field of endeavor—and especially in one like medicine, which deals primarily with the human condition. The humanities might actually provide an indispensable language for exploring that strange, nuanced, and often nonsensical land called the human condition.
The humanities may indeed promote the very personal qualities we measured. For instance, observing drama increases empathy,47 as does the performance of acting techniques;48 an elective course in medical humanities nurtures empathy;49 reflective writing may help improve medical students’ well-being;50 drawing enhances the reading of faces;51 and observation of art improves the art of observation.52 Even good literature prompts better detection of emotions53—all fundamental skills for a physician, although not prerequisites for medical school admission. Lastly, creativity, a quality we did not measure, has also been linked to a broad education and a multifaceted mind. In fact, Nobel laureates in science are often polymaths: 22 times as likely to perform as actors, dancers, or magicians; 12 times as likely to write poetry, plays, or novels; seven times as likely to dabble in arts and crafts; and twice as likely to play an instrument or compose music.54
The importance of wide-ranging interests raises the issue of whether exposure to the humanities might not be the true correlate of students’ desirable qualities, but instead a reflection of some other variable we did not measure. In a 1999 essay, Dr. Faith Fitzgerald asked this question,55 and concluded that what may really determine students’ desirable traits is curiosity. This has received limited attention in medical education research. In fact, current education practices may even hamper curiosity.56 But it is possible that interest in other activities, such as religious practice or meditation, volunteer work, sports, or politics, may similarly benefit the mental lives of our medical students.
Lastly, if exposure to the humanities plays a role in fostering important traits, what is more beneficial: an active or a passive student’s involvement? In our study, post hoc analyses remained significant regardless of whether we included active, passive, or both types of involvement. This suggests that the link between our variables of interest is robust, but also prompts further questions as we seek to better understand the role played by the humanities, whether in fact they can be taught or instead should be a prerequisite for medical school admission, and lastly, how an omnivorous curiosity might not only be of benefit but also be preserved during medical education.
In summary, our study empirically confirms what many have intuitively suspected for years: exposure to the humanities is associated with both important personal qualities and prevention of burnout. In fact, one could argue that some of the qualities we measured (tolerance for ambiguity, empathy, emotional appraisal of self and others, resilience) are, together with wisdom, fundamental components of professionalism.57 Hence, if we wish to create wiser, more tolerant, empathetic, and resilient physicians, we might want to reintegrate the humanities in medical education. This is nothing new. Commenting more than 100 years ago on the risk of burnout, Rudolf Virchow exhorted students to cultivate the humanities: “You can soon become so engrossed in study, then [in] professional cares, [then] in getting and spending, you may so lay waste your powers that you find too late with hearts given away that there is no place in your habit-stricken souls for those gentler influences that make life worth living.”58
