What is extremity bias?

What is extremity bias?

• A. The tendency to choose responses at or near the ends of a scale.
• B. The tendency to choose midpoint responses.
• C. The tendency to agree with statements regardless of content.
• D. The tendency to avoid using the scale.

Answer: (A)

Extremity bias is a response style in which people disproportionately choose the ends of a rating scale—strongly agree or strongly disagree—rather than selecting neutral or middle options. This pattern makes extreme views appear more common and can distort measurements of attitudes, which is especially important to recognize in cross-cultural research where different groups may differ in how freely they use extreme categories. For example, on a five-point scale, someone with extremity bias would more often pick the ends than the middle, signaling strong opinions more than warranted. The middle-option tendency reflects central tendency, not extremity; agreeing regardless of content describes acquiescence; and avoiding the scale describes nonresponse. Thus, choosing responses at or near the ends of the scale correctly captures extremity bias.
