Point: lim - the variability between social norms in different cultures and even different situations.
Evidence: For example, the experience of hearing voices is the norm in some cultures (messages from ancestors) but would be seen as abnormal in the UK.
Explain: This variability complicates the assessment of deviation from social norms, as what is considered abnormal in one culture or context may be normal in another.
Link: Thus, the criterion of deviation from social norms requires careful consideration of cultural and situational factors to accurately assess abnormal behaviour.
