Which term refers to making a judgment based on personal opinions?

The term that refers to making a judgment based on personal opinions is bias. Bias is defined as a tendency to favor one perspective, group, or idea over others, which often leads to subjective conclusions rather than objective ones. In contexts such as writing, decision-making, or analyzing information, bias can result in distorted interpretations because it is influenced by personal feelings or opinions rather than facts.

In contrast, an autobiography is a self-written account of one's life and does not inherently involve judgments based on opinion. Irony refers to a situation where there is a discrepancy between expectation and reality, often highlighting a deeper meaning or sense of humor. Allusion is a reference to another work, event, or person that enriches the content but does not involve personal judgment. Bias specifically addresses the influence of personal beliefs on judgment, making it the correct choice in this context.
