There seems to be near-universal consensus that Eminem is Introverted whereas there is disagreement about the other letters.
In our view, he clearly prefers Sensing. As a world-class rapper he is noted for his use of rhyme and assonance which is to say for the sound of his lyrics rather than for any abstraction in them. Indeed, his content is highly grounded with many references to life as it unfolds around him and hardly any mention of concepts, visions of the future, or events and politics removed from his own life.
In order to make the case that Eminem is also F and P, we must invoke the cognitive functions.
Many seem to believe Eminem prefers Thinking because he can be unsmiling and cool in interviews and because his lyrics are aggressive. However, not all Feelers are friendly and people-pleasing (and not all Thinkers are hostile!); rather such disengagement is the sign of someone who introverts Feeling (Fi users) which is true of FPs and TJs. We posit that Eminem’s primary judging function is Introverted Feeling (Fi), making him one who feels deeply and passionately and inwardly, fueling the flaming intensity of his expression. Thinking is an analytical function; it has nothing to do with anger.
Introversion, Sensing, and Fi user add up to ISFP. We might add that Eminem seems like a laidback Perceiver rather than a structured Judger. Also, invoking the cognitive functions again, the above description of Sensing is really one of Extroverted Sensing (used by SPs and NJs), not Introverted Sensing (used by SJs and NPs), which again suggests P (if one accepts that Eminem is a Feeler).
