Catching up in reading time lost over the holidays! Good post, Leigh, on a topic that's near and dear to my heart (writing a book that includes it).

Here are some definitions from Dona Lewandowski in “Understanding and Avoiding Bias and Stereotyping in the Judicial Process,” Institute of Government, April 2007, pp 24-28, that illustrates the distinctions in terminology that’s somewhat similar yet totally different:

"Bias:  a tendency to favor or disfavor; a preference.
Stereotype:  an oversimplified belief about a personal attribute about a group of people.
Prejudice:  negative prejudgment of a group and its members.
Discrimination:  unjustifiable negative behavior toward a group or its members; denial of equal rights based on stereotypes and prejudices."
