“…Newell and Simon, for instance, attempted to design computer programs that could solve a wide variety of problems using general domain-independent problem-solving rules Simon, 1956, 1972). Pioneers of research into medical problem solving, following the lead of the influential Newell and Simon work, looked for general medical problem-solving skills by identifying the number and sequence of questions while solving a medical problem (Rimoldi, 1955(Rimoldi, , 1961, similarities in data-gathering behavior (Donnelly et al, 1974;Juul et al, 1979), or the structure of the pathways throughout the diagnostic reasoning process (McGuire, 1976;McGuire and Babbott, 1967). Elstein et al (1978) initially discovered that the medical problem-solving process was characterized by generating multiple hypotheses early in the patient encounter.…”
