ABSTRACT
A group of colleagues is discussing current events over dinner at a conference. A new topic comes up. Some of the people at the table immediately express their evaluation of the topic. Others at the table are a bit slower to express their views. In talking to this second group, it is clear that some of them have not thought about the issue much at all. Others have clearly thought about the issue but are unsure how they feel-they know the arguments on both sides, but have not decided which set of arguments is the most persuasive. Still others have a clearly defined attitude: They know how they feel, but they seem to just not have thought about the issue for a while and seem a bit rusty.
