a prescriptive dimension along which psychological theories can be evaluated. Methodological objectivism is the position that methods of investigation can be, and should be able to be, repeated and verified by another investigator. Methodological subjectivism is the position that methods cannot be repeated and thus cannot be verified by another. See also contentual objectivism versus contentual subjectivism.
