weaknesses - flawed evidence
research with the f-scale has provided the bias of an explanation of obedience based on authoritarian personality.
however, green stein calls the f-scale a comedy of methodological errors' because it is a seriously flawed scale.
for instance, it is possible to get a high score just by selecting agree answers. this means that anyone with this response bias is assed as having an authoritarian personality.
therefore when considering research conducted using the f-scale we need to consider how useful is the f-scale in helping us understand obedience.
