““The differences in alter personality states' self-concepts can be striking, but authorities routinely stress that these are more apparent than real (e.g., Putnam, 1989a; Kluft, 1991). Various typologies have been offered, but few systematic data exist. Types of MPD alters, such as child-like personality states, angry alters, protectors, and persecutors, are found often enough to warrant further investigation.””
