A subjective opinion, preference, prejudice or inclination, that influences an individual’s or group’s ability to evaluate a particular situation objectively or accurately; a preference for or against. Reasonable apprehension of bias exists when a reasonable person knowing all of the relevant facts would believe that an individual or group’s decision was not impartial nor based solely on the evidence or information before the decision maker(s) but rather based on or influenced by personal extraneous factors. Bias can be real, potential or merely perceived.
