person may be defined as abnormal = when they behave in a way that is different from how they are expected to behave
societies and social groups make collective judgements about 'correct' behaviours in particular circumstances
social norms are culture bound
there are relatively few behaviours that would be considered universally abnormal => definitions are related to cultural context
includes historical differences within the same society
eg = homosexuality is viewed as abnormal in some cultures but not others and was considered abnormal in our society in the past
also = the degree to which a behaviour is abnormal depends on how extreme the deviation is and how important the norm is
eg = not saying “thank you” might be somewhat abnormal – but it’s not dangerous, just rude
example = antisocial personality disorder (formerly psychopathy)
an important symptom of antisocial personality disorder is a failure to conform to 'lawful and culturally normative ethical behaviour'
a psychopath is abnormal because they deviate from social norms or standards (they generally lack empathy)
strength = RWA
deviation from social norms is useful in the diagnosis of antisocial personality disorder because this requires failure to conform to ethical standards
deviation from social norms is also helpful in diagnosing schizotypal personality disorder which involves 'strange' beliefs and behaviour
means that deviation from social norms is useful in psychiatric diagnosis
limitation = social norms are situationally and culturally relative
a person from one culture may label someone from another culture as abnormal using their standards rather than the person's standards
eg = hearing voices is socially acceptable in some cultures but would be seen as a sign of abnormality in the UK
means it is difficult to judge deviation from social norms from one context to another
extra evaluation = human rights abuses
reliance on deviation from social norms to understand abnormality can lead to abuse of human rights (eg nymphomania (as a disorder) to control women)
HOWEVER = we need to be able to use deviation from social norms to diagnose conditions such as antisocial personality disorder
=> overall, the use of deviation from social norms to define abnormality may do more harm than good because of the potential for abuse
