The physical components of the human mind alone do not adequately explain the human experience. Neurons may provide the material for human consciousness, but they alone don’t create it. The soul-searching process of risk-taking involves more than evaluating what the people see and hear: it’s a biological process—part physiological, part psychological, and part contextual—but not always rational. Before the discovery of insulin, diabetes led to death. Doctors knew that sugar worsened the condition of diabetic patients and that the most effective treatment demanded putting the patients on extremely strict diets with sugar intake, and food in general, kept to a minimum. The quantity of information isn’t the only thing that stands at cross-purposes with the people risk-taking. In the early 1900s, American psychologist Lewis Terman recognized the importance of intelligence when he pioneered the Stanford-Binet and other IQ tests, using children as many of his study participants.
