Which statement is most true about appraisers and bias?

• A. Bias is acceptable if it helps meet client demands
• B. Appraisers should act on gut feelings first
• C. Appraisers must not allow biases to affect their value opinions and conclusions
• D. Bias is only a concern in neighborhood analysis

Answer: (C)

Maintaining objectivity and independence is essential in appraisal work. Appraisers must base value opinions on verifiable data, sound analysis, and appropriate methods, free from personal feelings, stereotypes, or external pressure. That’s why the statement that appraisers must not allow biases to affect their value opinions and conclusions is the most accurate. When bias slips in, it can distort data selection, adjustments, and conclusions, undermining credibility and potentially leading to professional discipline. The other ideas would let bias influence the outcome—either by bowing to client demands without ethical basis, relying on gut feelings rather than evidence, or assuming bias only affects neighborhood analysis—none of which align with professional standards.
