Piaget called a natural biological tendency to interact with and respond to the environment

Doug is enamored of the humanistic approach to understanding personality. He identifies the five most "evolved" people he personally knows—folks who are smart, witty, spiritually-centered, creative, and adventuresome—and interviews each in depth. At the conclusion of his investigations he finds that they are all quite self-actualized. What is the central problem with Doug's approach?

A. He may have fallen prey to the blacktop illusion; Doug was unable to see past the "humanistic horizon" proposed by Maslow. B. He may have fallen prey to the simulation heuristic; he imagined what these people would be like, and interacted with them accordingly. C. He may have fallen prey to an elusive correlation; he underestimated the magnitude of the relationship between personality and behavior. D. He may have fallen prey to the confirmation bias; Doug interviewed people he thought would be self-actualized, and discovered they seemed to be self-actualized.
