Abstract:
Dr. Warren Bickel tirelessly investigated delay discounting (DD), a behavioral economic index of impulsive decision making, as a determinant of numerous health outcomes. Among the factors that contribute to a person's level of DD, a burgeoning body of research has illuminated its genetic foundations and the extent to which it may be a mechanistically informative phenotype for genetic contributions to addiction, obesity, attention-deficit/hyperactivity disorder, and a wide array of other health behaviors. In this review, we provide a concise history of quantification of DD as a human decision-making phenotype, tracing its origins from economics and operant learning theory, and critically synthesize the existing evidence on its genetic architecture. Finally, despite innate genetic contributions, we also discuss evidence that DD is a modifiable health behavior, with high potential in precision medicine.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
