Abstract
Good decision-making requires reliable information. In medicine, relevant information comes from clinical trials and other forms of scientific research. In business, one source is in corporate annual financial statements. As for-profit, publicly traded companies whose business is discovering, manufacturing, and marketing drugs, pharmaceutical companies sit at the nexus of these two fields. Determining the safety and efficacy of a pharmaceutical product and determining the profitability of a complex enterprise are similarly difficult tasks: each is fraught with deeply ambiguous information that requires sophisticated judgment to interpret reasonably.
