The meanings adopted for the term "objectivity" in the field of psychological knowledge have been so numerous and divergent that the concept has become a veritable palimpsest. Depending on the theory, approach or current that is chosen as a reference standard, the notion of objectivity acquires diverse and even antagonistic meanings. This situation -perhaps typical of the state of development of our discipline- has significantly diminished communication among psychologists to such an extent that, frequently, dialogue among them has become practically impossible.
