Are goals of science appropriate? Some psychologists do not see the
study of behaviour as a scientific pursuit. They think that treatment
resulting from research can only be appropriate if Psychology takes a
idiographic approach (looking at each individual case) where as science

Scientific methods don't always work: the treatments that result from
research into mental illness are not consistently successful which suggests
the goals of science aren't always appropriate.
