Yes. It occurs when one thinks over false paths, unsubstantiated conjecture, or irrelevent data to reach a conclusion.

Fine, C3PO. That's alright if you like a robotic approach. But why use rationality as a guiding principle for your life? Or, even if you do, why follow it with such dedication that you never detract from it? Why, when you are doing something, would you ask "is what I'm doing rational?" out of the many existential questions you could ask yourself? Examples of other questions could be "is what I'm doing enjoyable to me?", "will what I'm doing procure me some kind of material/spiritual gain in the future?", etc. Or, you could simply do things without asking yourself these questions.
