Biographical narratives are not descriptions of individual persons’ mind and personality development. They are stories about the individuals’ life courses. Although the timing of developmental changes falls within the life course, one is not identical to the other. Despite the differences in perspective on narrative psychology between Elzbieta Dryll (2024) and Marian Olejnik (2024), they both seem to accept the aforementioned identity as true. Although any kind of developmental change happens within the life course, one cannot say that each of the individual changes happening within the life course is a developmental one. Biographies are life-course descriptions, and as such they are a type of literary work that lies outside of the psychological science. Biographies are objects of the socio-cultural world and may become subjects of psychological science investigations.
