Again, a beginning has been made. It is not a big step from replacing a broken part to replacing a part with another part which is better by some criterion. When that happens expect humanoid robots to appear with an astonishingly complex variety of personalities. This limitation of knowledge doesn't prevent personality theorists of all kinds from making intelligent pronouncements on human personality and it won't prevent them from making pronouncements on robot personality. However, some warnings about the Wonderland of personality analysis in general are called for.
Personality refers to the ways people perceive and interpret behavior.
Behavioristic analysis convincingly demonstrates its reality and a few sessions in court watching as expert testimony is presented regarding personality assessment will convince anyone of the power in the profession. Taking it lightly is folly. In my opinion what Fiske is describing is the problem of reliability and validity in personality assessment. However, there is much room for imaginative projections onto the subject. But geology has problems with reliability and validity too, and its status as a science is not disputed.
