Deviation from Social Norms:
'when a person behaves in a way that is different from how we expect people to behave'
groups of people choose to define behaviour as abnormal on the basis that it offends their sense of what is 'acceptable' or the norm -> we are making a collectivejudgement as a society about what is right
Deviation from Social Norms Example (Antisocial Personality Disorder -APD):
an individual with APD is impulsive, aggressive + irresponsible
according to DSM-5 1 important symptom of APD is an 'absence of prosocial internal standards associated with failure to conform to lawful or culturally normative ethical behaviour'
we are making social judgement that a psychopath is abnormal because they don't conform to our moral standards -> psychopathic behaviour would be considered abnormal in wide variety of cultures
