Abstract
Clinical decision making requires that clinicians think quickly and in ways that will foster optimal, safe client care.Tradition influences clinical decision making, enhancing efficiency of resulting nursing action; however, since many decisions must be based on data that are either uncertain, incomplete, or indirect, clinicians are readily ensnared in processes involving potentially faulty logic associated with tradition. The author addresses the tenacity of tradition and then focuses on three processes-consensus formation, the grounding of certainty in inductive reasoning, and affirming the consequent-that have affected clinical decision making. For some recipients of care, tradition has had a substantial and invalid influence on their ability to access care.
