"Social desirability bias occurs when respondents give answers to questions that they believe will make them look good to others, concealing their true opinions or experiences. It often affects studies that focus on sensitive or personal topics, such as politics, drug use, or sexual behavior."
I would add an alternate form of this bias called Moral and Taboo Desirability bias, where the person will give answers to questions based vaguely on what they think Jesus would say;
Or how they would look in front of people that are not present, or when they answer a certain question in a way that they feel would violate a taboo..... "of course a 50 year old shouldn't be able to date an 18 year old girl right out of High school! I see that when a taboo or moral situation get more into grey areas, the bias becomes less effective at increasing cognitive efficiency, more exaggerated in its expression, and much more error prone, i.e, producing responses that are absurd.
