We begin this book with an unspoken “belief” that is likely subconsciously held; it is most aptly said to be a description of what people often do without realizing or taking responsibility for it – viewing women (and other marginalized groups) through a certain lens. This is typically done in the process of stereotyping them. People may be stereotyped descriptively, whereupon they are seen as being a certain way more readily than are others. This occurs with women when, for example, a woman is perceived as being “pushy” and “abrasive” when she is assertive at work, whereas a man who acts similarly is perceived as being “strong” or “tough.” Women may also be stereotyped prescriptively, whereupon they are expected or anticipated to be a certain way that others are not. This occurs, for example, when a performance review suggests that a female employee is “not that nurturing,” in some capacity, but does not even evaluate a similarly situated man for the same characteristic.
