_________ are attitudes that contain a 'should' or 'ought' aspect.

Values are attitudes or beliefs that contain a ‘should’ or ‘ought’ aspect, such as moral or ethical values. One example of a value is the idea that one should work hard, or that one should always be honest, because honesty is the best policy. Values are formed when a particular belief or attitude becomes an inseparable part of the person’s outlook on life. Consequently, values are difficult to change.

Beliefs, stereotypes, and prejudice are not attitudes that contain a "should" or "ought" aspect.

• Beliefs are statements about the world that we believe to be true.
• Stereotypes are generalizations about groups of people that are often inaccurate and oversimplified.
• Prejudice is a negative attitude towards a group of people that is not based on reason or experience.
