Ethical issues arise when there is conflict between the reseachers need to gain validity and preserve the rights of the participants.
Sp ethical guidelines were established. But this doesnt solve the socal impact on the participants after the study has been conducted. And how the findings will be represented in the media and effect the work and perception of some social groups.
Some research is more social sensitive than others. Eg cognitive research into long term memory will be less likely to produce damaging consequences. However a research investigating the genetic basis of criminality will. This is because they attract attention from the media and public.
But this shouldn't stop the research from being done as psychologists have a social responsibility to carry it out.
Scarr argues studies that are of the underrepresented groups will increase social sensitivity but also increase the understanding of these groups. Also benefitted society eg research into the reliability of eyewitness testimony- reducing the risk of miscarriages of justice.
the research has been used to shape social policy without fully considering the effects of the environment on characteristics. research can still be seen as harmless and have socially sensitive consequences. eg: a study that made coke and popcorn sales increase as a result of showing them at cinema's, when conducting a study on persuasive effects of subliminal messages. but the findings were fake.
