The much larger set of studies potentially relevant to our present discussion are demonstrations that, in the laboratory and in everyday life, the behavior of a given individual with respect to willingness to take risks or delay gratification or to display cooperativeness or altruism (or many other dimensions that we typically think of as personality, temperament, or character) is apt to vary and appear “inconsistent” across settings. Some of that variability is random, or at least a product of factors that we cannot discern.
