Psychology - social psychology

I think that deception is needed so that the true behaviour of people can be studied. As they don’t know the true aim of the study, they won’t display demand characteristics and will act naturally. That way, we can see the effect of social interactions and the social environment on their behaviour.

I’m not sure what social studies you look at but deception can be dealt with in social psychology by doing carrying out retrospective consent after the study. For example, getting participants to sign an informed consent form after taking part in the research - so that they act naturally during research but give consent afterwards. For example, bocchiaro revealed the true aim of his study after the participants took part and afterwards they also completed an informed consent form.
