Deviation from Social Norms - Evaluation
STRENGTH - Applicable in the real world as it's used in clinical practices to diagnose disorders.
LIMITATION - Lacks cultural relativity, with not every "deviating" behaviour being considered a deviation from all societies/cultures social norms. For example, hearing voices in the UK would mean you have Schizophrenia, but in other cultures these could be signs/voices of ancestors.
LIMITATION - Can be used in a way which abuses human rights. For example, slave owners created a disorder for slaves who ran away from captivity, therefore no one was able to question what occurred when they were brought back. Men also had a disorder for women who were "too sexual", using it as a way to control them.
