TRUE regarding the number of types of biases that exist?

• A. There is a universal fixed number of biases in appraisal
• B. Different academic sources offering differing opinions regarding the number of types of bias that exist
• C. All sources agree on the exact count
• D. Bias types do not have fixed counts in literature

Answer: (B)

There isn’t a universal fixed number of bias types in appraisal literature because scholars define and categorize biases differently. Some sources group biases into broad categories and then list subtypes, while others count only specific, named biases or include newer domain-specific ones. These definitional choices change what counts as a distinct bias, so different academic sources arrive at different counts. That’s why the statement that different sources offer differing opinions about how many bias types exist is the most accurate reflection of the literature. The idea that there’s one fixed number or that no counts at all are discussed doesn’t fit how the field actually treats bias—counts vary by how biases are defined and categorized.
