How to Diagram “Unless” LSAT Logical Reasoning Questions

Welcome to our ongoing series on the more nefarious elements of diagramming.

Topping the agenda today are “unless” questions. These are much more straightforward than the “only” conditionals we reviewed last week. Unlike “only” questions, which require one to search for the referent, “unless” questions have a more standardized approach. Consider the following:

“Unless I just brushed my teeth, you’ll find me sipping a cold glass of orange juice”

What does this mean? It tells us that, in all cases where I haven’t just finished brushing my teeth, I’ve got a tall glass of nature’s goodness by my side. To simplify: if I have not just brushed, then I’ve got OJ. Look diagrammable?
