"A bias is a prejudice in a general or specific sense, usually in the sense for having a preference to one particular point of view or ideological perspective. However, one is generally only said to be biased if one's powers of judgment are influenced by the biases one holds, to the extent that one's views could not be taken as being neutral or objective, but instead as subjective. A bias could, for example, lead one to accept or deny the truth of a claim, not on the basis of the strength of the arguments in support of the claim themselves, but because of the extent of the claim's correspondence with one's own preconceived ideas."

Objective - "Uninfluenced by emotions or personal prejudices: an objective critic.
Based on observable phenomena; presented factually: an objective appraisal."
