What term describes a preference that interrupts an appraiser's impartiality?

The term that describes a preference that interrupts an appraiser's impartiality is bias. Bias refers to a tendency to favor one particular perspective or viewpoint over others, which can cloud judgment and affect the objectivity of an appraisal. When an appraiser exhibits bias, it may lead to a valuation that does not accurately reflect market conditions or the true value of the property being assessed.

In appraisal practice, maintaining impartiality and objectivity is crucial to ensuring that valuations are fair, credible, and reflective of the market. The presence of bias can undermine the integrity of the appraisal process, leading to potential legal and ethical consequences.

While partiality, conflict of interest, and subjectivity are related concepts, they capture different nuances. Partiality refers broadly to a lack of impartiality, but bias specifically emphasizes the prejudgment that affects decision making. Conflict of interest pertains to a situation where an appraiser has a vested interest that could compromise their ability to remain impartial, while subjectivity is about personal perspectives that influence opinions but does not inherently carry the same notion of unfair preference as bias does. Therefore, bias is the most accurate term to describe preferences that interfere with impartial appraisal practices.
