ABSTRACT
Human personality is typically considered to reflect a person's "true" self or "core" identity, stable and unique relative to other measures of behavior over time. This concept of personality makes it difficult to envision a healthy person having two personalities. On the other hand, personality is also considered to be an attribute of groups and societies. Thus, people might talk about an "Anglo," a "Mexican," or a "Chinese" personality when trying to categorize the types of behaviors believed to be characteristic of these ethnic groups.
