Question

which source of bias is most relevant to the following situation:

both members of a couple are asked to indicate if they have remained monogamous in their currently relationship.

• self-interest study
• voluntary response bias
• nonresponse bias or missing data
• perceived lack of anonymity
• loaded or leading question

Explanation:

🆕 New Concept Discovered: Sources of Bias in Surveys
Fear of judgment affects honest responses.

Step 1: Analyze the scenario

In this scenario, both members of a couple are asked to disclose highly sensitive and personal information: whether they have remained monogamous in their current relationship.

Step 2: Evaluate the options

• Self-interest study: This occurs when the researchers conducting the study have a vested interest in the outcome (e.g., a company funding a study on its own product). This is not indicated here.
• Voluntary response bias: This occurs when sample members are self-selected volunteers (like an online poll). The prompt does not focus on how the sample was recruited.
• Nonresponse bias or missing data: This occurs when a significant portion of the sampled individuals choose not to respond, potentially skewing the results. While some might refuse to answer, the primary issue with the question itself lies in the truthfulness of the responses given.
• Perceived lack of anonymity: When individuals are asked sensitive questions—especially in front of or in connection with their partner—they may fear that their answers are not private. If they believe their partner or others might find out their answer, they are highly likely to lie to avoid conflict or social embarrassment. This fear of a lack of privacy leads to response bias.
• Loaded or leading question: This occurs when the wording of the question itself nudges the respondent toward a specific answer. The question "have you remained monogamous" is direct rather than worded in a leading way.

Step 3: Identify the most relevant bias

Because the question involves highly sensitive relationship dynamics, respondents who have not been monogamous are highly likely to lie if they feel their partner or the researcher can link the response back to them. Therefore, a perceived lack of anonymity is the most critical source of bias in this situation.

Answer:

perceived lack of anonymity
