A process of deciding whether you care or have an opinion about any thing, policy, concept, idea, etc, by stripping it down to its most basic parts. If you are motivated enough to have a position/opinion on any of its parts, then it can be said you give a rat's ass about the topic.

Basically a way of determining whether you give a rat's ass about a specific issue, topic, etc.
