Office worker: I have two equally important projects that remain undone.
Conclusion (should = opinion)
I should devote all my time to the second one.
Evidence
It's equal in importance to the first project, the first one is late already, and if I work on the first then I won't finish the second before it's deadline.
Evaluate / Goal
We need a rule that tells us which project to work on. It should have a trigger that applies to the situation this worker is in, and an outcome that makes it seem like the worker .
