Genetic studies of typical schizophrenia require accurate means for the detection of carriers of the heritable diathesis. Psychometric methods have been developed, often for studying psychosocial transmission of schizophrenia, that might be useful for genetic studies. Studies of schizotypy detection using the Goldstein-Scheerer Object Sorting Test, Rorschach technique, TAT, and MMPI are reviewed. Most studies suffer from serious conceptual and methodological flaws that have made replication a rarity. Recent approaches emphasizing clinical signs and symptoms that bear a close content relationship to the typical schizophrenic syndrome are asserted to be more likely to bear fruit.
