Question

Quizplus · Accepted Answer

Researchers may prefer a survey with low face validity when they are investigating sensitive or controversial topics that participants may be hesitant to disclose information about. By using a survey with low face validity, researchers can mask the true purpose of the study and reduce the chances of participants changing their responses or dropping out of the study altogether.
