Caplan's lifelong focus on medical ethics originated from his childhood polio hospitalization, where doctors were untruthful with patients and families were kept at a distance. This formative experience instilled in him a deep skepticism of medical authority and a focus on patient rights and transparency.
The field of research ethics, once focused on protecting vulnerable subjects from harm, has evolved. A cultural emphasis on individual liberty, exemplified by the "right-to-try" movement, has created a new ethos where patients demand access to experimental treatments, even with high risks.
Arthur Caplan argues that while AI in healthcare has issues, the most profound ethical debates will center on neuroscience. Directly modifying the brain raises more immediate questions about personal identity, free will, and equity than genetic engineering or AI, as the link from brain to behavior is much shorter.
Vaccine mandates and quarantines are fundamentally based on a communitarian ethic—a responsibility to protect others. This clashes with the hyper-individualistic "liberty" framework that prioritizes personal choice. Bioethics failed to articulate this crucial distinction, leading to backlash against public health measures.
COVID decimated public trust in vaccines not just through politicization, but through disappointment; the public expected a quick "conquest of disease." This perceived failure allowed the anti-vaccine movement to successfully pivot from safety concerns to a more potent message of individual liberty and choice.
Arthur Caplan's initial attempt to teach medical ethics to medical students using classical philosophy was a complete failure. He learned that to effectively engage physicians, ethics must be taught through practical, case-based scenarios that mirror how they learn clinical medicine.
Bioethicist Arthur Caplan argues that the American healthcare system is distorted by commercial incentives. The decision to diagnose a condition is often driven less by its medical severity or cultural context and more by the simple availability of a profitable diagnostic test that can be billed for.
At NYU, bioethicists concluded that limb transplants are often not the best ethical choice. The quality of modern prosthetics has advanced so much that it's preferable to avoid a transplant that would condemn the patient to a lifetime of immunosuppressant drugs and their associated health risks.
