- Think of times you’ve been in a similar situation and explain your reaction
- Can the behavior be explained by a more “universal” model than a person-specific one?
- How are they empathizing with you, given they are projecting?
- How are they empathizing with you, given what you know about how they perceive others?
- What successful model have you used to explain similar behavior for similar people?
- Is your conclusion affected by your attitude towards the subject?
This is, of course, a social convention, but the application of "generally" to the subject at hand is questionable. Notice also that I was responding to someone who interpreted Alice as attempting to deceive Bob, which is not necessarily the case.
