Bias vs. Biased
In recent years, we have seen more evidence of the adjectival bias in constructions like “a bias news program” instead of the more usual “a biased news program.” The reason is likely because of aural confusion: the -ed of biased may be filtered out by hearers, which means that bias and biased can sound similar in the context of normal speech. They are not interchangeable, however. The adjective that means “exhibited or characterized by an unreasoned judgment” is biased (“a biased news story”). There is an adjective bias, but it means “diagonal” and is used only of fabrics (“a bias cut across the fabric”).

In the past people deliberately lied, or they unconsciously colored what they wrote, or they struggled after the truth, well knowing that they must make many mistakes; but in each case they believed that 'the facts' existed and were more or less discoverable.—Leon Wieseltier, New Republic, 17 Feb. 2003The information experts say that it's dangerous to conclude very much from talking to people because you will never interact with a scientifically selected random sample. Thus, the information you derive from meeting people is biased or anecdotal.—Will Manley, Booklist, 1 Mar. 2002But even if you think I may be biased about the book's conclusions, please trust me about its awful prose.—James Martin, Commonweal, 3 May 2002
