Dysrationalia
Dysrationalia is defined as the inability to think and behave rationally despite adequate intelligence. Dysrationalia can be a resource to explain why smart people fall for Ponzi schemes and other fraudulent encounters. The concept of dysrationalia was first proposed by psychologist Keith Stanovich in the early 1990s. Stanovich classifies dysrationalia as a learning disability and characterizes it as a difficulty in belief formation, in assessing belief consistency, or in the determination of action to achieve one's goals. However, special education researcher Kenneth Kavale notes that dysrationalia may be more aptly categorized as a thinking disorder, rather than a learning disability, because it does not have a direct impact upon academic performance. Further, psychologist Robert Sternberg argues that the construct of dysrationalia needs to be better conceptualized since it lacks a theoretical framework (explaining why people are dysrational and how they become this way) and operationalization (how dysrationalia could be measured). Sternberg also notes that the concept has the potential for misuse, as one may label another as dysrational simply because he or she does not agree with the other person's view. Stanovich then replied to both Kavale and Sternberg. He has elaborated on the dysrationalia concept in a later book.
