From healing to harm

These questions transcend personalities.

The Covid-19 pandemic exposed longstanding tensions within medicine. Expertise remains essential, yet experts are fallible: they may disagree, models may prove inaccurate, and predictions may fail. Even well-intentioned policies can yield unforeseen consequences. The primary challenge is not to eliminate expertise, but to ensure that experts remain transparent, honest, and sufficiently humble to acknowledge the limits of their knowledge.

The pandemic also illuminated a further reality: contemporary medicine extends beyond clinical and laboratory settings. Scientific leaders now operate within a complex environment that includes governments, regulatory bodies, media, social media, industry, and international organizations. In this context, scientific decisions frequently carry significant political and social implications. Physicians and scientists in influential positions may find their impact extends well beyond the boundaries of medicine.

Such influence imposes extraordinary responsibilities.

The exercise of authority amid uncertainty requires honesty and intellectual humility. Public trust is reinforced not by the projection of infallibility, but by the candid acknowledgment of knowledge gaps. Leaders must remain open and humble when wielding power during uncertain times. Trust is enhanced when experts admit the limits of their knowledge, rather than feigning certainty. Most individuals can tolerate uncertainty if it is communicated honestly. However, trust erodes when advice is presented as definitive and later revised without acknowledging the evolving nature of knowledge. The rapid pace of scientific advancement often outstrips society's capacity to fully assess its implications. Innovations in biotechnology, artificial intelligence, genomic editing, and high-risk biological research offer substantial benefits while simultaneously introducing new ethical challenges.¹â»â´,â¸,¹â°

The issue is not whether scientific research should continue. It must. The issue is whether scientific capability and ethical wisdom advance at the same pace.

History suggests that they often do not.

Physicians and scientists possess ethical obligations that extend beyond technical competence. Knowledge, expertise, and intelligence alone are insufficient. The responsible exercise of power necessitates less quantifiable qualities such as sound judgment, humility, openness, and receptivity to criticism. Scientific leaders must remain open to scrutiny, particularly given the potentially serious consequences of errors.

Humility is not the enemy of expertise. It is its necessary companion.

Being humble means knowing that our knowledge is incomplete. It means accepting that mistakes can happen and that smart people can honestly disagree. What seems certain today might be proven wrong tomorrow. Most of all, humility means that leaders should always be open to being questioned.âµâ»â¸ Every generation of doctors believes it is more enlightened than the last. In many ways, this confidence is justified because scientific progress has been remarkable. Yet history shows that each generation also has blind spots that only become clear later.

The purpose of medical history is not to equate contemporary practitioners with those responsible for past ethical failures. Such comparisons are unproductive. The more challenging lesson is that ethical problems often emerge gradually. They arise when certainty replaces curiosity, when dissent is viewed as problematic rather than integral to science, and when established protocols are bypassed in the name of urgency.

Every generation believes it will never repeat the mistakes of the past. History encourages caution.

The moral standards that emerged after the catastrophes of the 20th century-from the Nuremberg Code to the Belmont Report and the Declaration of Helsinki-were built upon a common recognition: scientific capability, however extraordinary, must always remain subordinate to human dignity, transparency, and moral restraint.¹â»â´
