Bioethics

Bioethics is an interdisciplinary field that studies the ethical, social, and legal implications of biological and medical advances. It covers clinical practice, biomedical research, public health, genetics, neuroscience, environmental biology, and related technologies, along with the policies and institutions that govern their use. The goal is to identify values, balance benefits and harms, and guide responsible decision making.

A central framework in bioethics is principlism, which emphasizes autonomy, beneficence, non-maleficence, and justice. Other approaches include virtue ethics and care ethics, and methods such as case-based reasoning and empirical bioethics. Ethics committees, institutional review boards, and professional codes play key roles in evaluating research protocols and clinical practices.

The modern field emerged in the mid-20th century in response to abuses in medical research, with landmark milestones such as the Nuremberg Code (1947), the Belmont Report (1979), and the Helsinki Declaration (1964, revised). These initiatives promoted informed consent, risk minimization, and respect for subjects.

Common topics include informed consent in patient care, end-of-life decisions, reproductive ethics, genetics and gene editing, stem cell research, organ transplantation, and fair allocation of scarce resources. Data privacy, biobanking, animal welfare, and environmental impacts are also central concerns.

Contemporary debates address genetic enhancement, CRISPR and gene drive technologies, behavioral genetics, access to expensive therapies, and global disparities in research and care. Bioethics also engages with policy, law, religious and cultural values, and the governance of dual-use research and emerging biotechnologies.

Critics argue that some frameworks reflect Western norms and may overlook cultural diversity. Ongoing work seeks pluralistic, inclusive approaches that integrate empirical data, clinical experience, and philosophical analysis to inform practice and policy across settings.
