Final answer:
Behavioral economists suggest that there might be systematic patterns to what was traditionally labeled as irrational behavior, and these patterns indicate underlying reasons for such behavior. Personal and impersonal factors both influence rational and irrational actions, making predictably irrational behavior an interesting point of study in both economics and political science.
Step-by-step explanation:
The relevant findings related to personal vs impersonal irrationality are not precisely given by Evans, but behavioral economists, such as those mentioned in the reference material, have significantly contributed to this field. The insights provided by these economists suggest that irrational behavior might not be as sporadic or nonsensical as traditionally perceived; instead, they propose that there is often a systematic pattern to behavior that could have been previously labeled as irrational. These patterns indicate that while people know what they should logically do, such as saving money or taking care of their health, they often do not follow through due to deeper underlying reasons that drive their behavior.
In political science, a person's irrationality doesn't necessarily mean their actions are completely random or unpredictable. In fact, people might be predictably irrational due to various psychological factors influencing their decision-making processes. Therefore, answering the multiple-choice question directly is not possible with the given information, but it highlights that personal and impersonal factors both have roles in influencing rational and irrational behavior.
