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”).

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
