Most, but not all, sociologists agree that it is unethical to misrepresent themselves.
In any type of investigation, it is important that the researcher identifies himself, the purpose of his investigations and requests the consent of the respondents. The sociologist and other researchers will question the idea of full disclosure during the investigation, citing changes in respondents. As sociologists study social patterns and relationships, it is expected that respondents in a sociological study will only present information that is considered socially acceptable, taking care of the political and cultural context of their points of view. For the sociologist, it is important to have a complete disclosure and to convince respondents to provide honest answers, that´s why its important to never misrepresent themselves, to be taken seriously.
