Disadvantages of using the scientific method
1 DEMAND CHARACTERISTICS
1.1 Disadvantage because: participants may guess the aim of research + try to please the researcher by behaving in a certain way
1.1.1 For example, in Milgram's experiment participants may have figured out the experiment aim and that the shocks were not real
1.1.1.1 They would have then responded differently, meaning the results would no longer be valid
2 LACKS ECOLOGICAL VALIDITY
2.1 Disadvantage because: means that findings of a study cannot be generalized beyond the settings in which they were conducted
2.1.1 For example, Loftus + Palmer's experiment lacked ecological validity
2.1.1.1 It wasn't real, participants only watched a video which would not be as emotionally stimulating as witnessing an actual event
2.1.1.1.1 Therefore, it may be argued that this should not have been generalized as it was not representative of real eye witness testimony
3 REDUCTIONIST
3.1 Disadvantage because: it may mean that complex subjects are over-simplified
3.1.1 For example: the monoamine theory of depression is reductionist
3.1.1.1 Suggests that depression is caused by a lack of these certain neurotransmitters only, it does not take other theories into account such as life events or the environment
4 IGNORES INDIVIDUAL DIFFERENCES
4.1 It is nomothetic and generalizes
4.1.1 Disadvantage because: culture, age, gender and other differences may be overlooked
4.1.1.1 Most psychological research is conducted on middle class, middle aged, white men
4.1.1.1.1 Asch's study is an example of this, the data obtained from this group of people that demonstrated willingness to conform would then have been generalized to everybody, which may not be valid or correct
5 ETHICAL ISSUES
5.1 This is most of a disadvantage when the ethical costs outweigh the scientific benefits
5.1.1 For example: Milgram's study - broke many ethical issues including protection from harm, many suffered mentally/ emotionally as well as physically (some had seizures)
5.1.1.1 Many argue that costs outweighed the benefits, meaning Milgram's findings would not be as credible
