God, but the methodology here is flawed to hell and back.
It's another example of people abusing MBTI as a system of classifying people rather than understanding cognition. The enumeration of subtypes does answer a deep-seated need for classification and systematizing, but that's the classic INTP trap where we lose objectivity in pursuit of our emotional need for consistency. What you're doing here is not classifying yourself, but your current mood. Use the Ti, Luke, and stay rational!
The person who wrote this doesn't seem to have any real basis for their thoughts and is not showing their work. And in a few places it seems deeply contradictory. Take the "Stoner subtype" - apparently inhabiting a fantasy world, they rank N lowest. How is that supposed to work? Intuition, Ne especially, is responsible for creative imagination. The perpetually daydreaming INTP should, logically, be more Ne dominant.
This system is not, however, worthless. I think it's worth taking a good look at it in terms of how your I, N, T and P manifest - as facets of your personality and cognitive style, not as who you are. For example, my introversion most frequently shows up in daydreaming, so the description of "the Stoner" is very accurate. On the other hand, my favorite manifestation of Thinking is "the Saboteur" - skepticism and the search for contradictions where matters of seeking truth are concerned. Which is basically what I'm doing right now.
