Librarians and information professionals cannot hide from bias: a prejudice for or against something, someone, or a group. As human beings, we all have biases. However, implicit biases are ones that affect us in an unconscious manner. Awareness of our implicit biases, and how they can affect our colleagues and work environment, is critical to promoting an inclusive work environment. Part one of this two-part article series will focus on implicit bias: what is implicit bias, how these biases affect the work environment, and best practices for reducing these biases within recruitment, hiring, and retention in the library workplace.
