Lack of impartiality

Impartiality (also called evenhandedness or fair-mindedness) is a principle of justice holding that decisions should be based on objective criteria, rather than on the basis of bias, prejudice, or preferring the benefit to one person over another for improper reasons.

To have no partialities is impossible if one is interested and involved, and the attempt to rid oneself of them and to reach such a high plane that all things may be regarded with equal equanimity is to move only towards increasing vacantness of mind and to allow oneself to utter only fatuities...To be impartial is still to have partialities and, depending on circumstance and fortune, to have to deal with issues on which one has specific partialities of thought and feeling. Without our distinctiveness of taste, we have only dullness of perception, and therefore not the perceptiveness required for objectivity...Partiality is essential to any objectivity, though it is equally a sharp risk.
