A preference or inclination that precludes an appraiser's impartiality, independence, or objectivity is known as?

The correct choice highlights the concept of bias, which refers specifically to a preference or inclination that affects an appraiser's ability to make impartial, independent, and objective assessments. When an appraiser is biased, it means they may favor a particular outcome based on personal beliefs, experiences, or interests, rather than relying solely on factual data or established appraisal processes. This lack of objectivity can significantly undermine the integrity of the appraisal process, as biases can distort the evaluation of properties and lead to unfair or inaccurate outcomes.

In contrast to bias, a conflict of interest involves a situation where an appraiser has competing loyalties that could influence their decisions, which is a broader concept. Discrimination pertains to unfair treatment of individuals based on protected characteristics rather than personal inclinations in appraisal. Partiality also implies a lack of neutrality but may not inherently indicate the systematic or entrenched preference that bias encapsulates. Therefore, recognizing bias is critical in ensuring fair appraisal practices, as it directly relates to the appraiser’s ability to remain objective and uphold the standards of their profession.
