A behaviour is seen as abnormal if it is statistically uncommon or not seen very often in society E.G. having a high IQ
Evaluation of statistical infrequency
Cultural relativism
P- an issue with statistical infrequency is that behavuours That are statistically infrequent in one culture may be statistically frequent in another culture
E- for example one of the symptoms of schizophrenia is claiming to hear voices. However this is an experience that is common in some cultures.
L- this suggests that there are no universal standards or rules for labelling a behaviour as abnormal
