In her commencement speech at WashU School of Medicine, Dr. Rochelle Walensky emphasized the importance of acknowledging uncertainty in the medical field. As young professionals enter this complex world, they must recognize that science evolves and adapts through a process of self-correction. This ongoing journey involves uncovering new insights and challenging previous assumptions. By understanding the provisional nature of scientific knowledge, these future doctors can better navigate the intricacies of their profession. The essence of scientific inquiry lies in its openness to revision and refinement, qualities that distinguish it from rigid dogma.

The distinction between science and fact plays a crucial role in shaping medical practice. Facts stand firm until compelling evidence arises to alter them, while science thrives on exploration and questioning. Achieving factual status requires robust, repeatable evidence supported by consensus among experts. In clinical medicine, uncertainties are inevitable, some of which cannot be entirely eradicated despite advanced testing methods. Thus, embracing and effectively communicating these ambiguities becomes essential for making sound decisions. This approach not only enhances patient care but also fosters trust between practitioners and those they serve.

As new graduates step into their roles as stewards of truth, they carry the responsibility to uphold intellectual honesty and defend reason. Their journey is one of continuous learning, where empathy serves as a vital tool alongside technical expertise. At the bedside, listening intently to patients' experiences enriches diagnostic and treatment strategies. In an era where facts face attacks and science undergoes distortion, these emerging professionals must advocate for integrity and accuracy. Through humility, curiosity, and courage, they will redefine medicine's boundaries, transforming uncertainty into understanding and guiding humanity toward healing and progress.
