Scientific research is desirable: people don't believe theories without
Psychology shares the goals of science but may just be `dressing up': most
sciences use well controlled experiments that can be falsified. However,
just because psychology uses scientific method, is may not be counted as a
Lack of objectivity and control: in Psychology, the object of the research
can react to the investigator which leads to problems of demand
characteristics and investigator effects.
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
tends to take a homothetic approach (tries to generalise human behaviour).
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.
Qualitative approach: some psychologists use more subjective qualitative
methods of conducting research. However, these methods are still scientific
as long as they aim to be valid.
reductionist: complex phenomena are reduced to simple variables in order
to study casual relationships between them.
