The reason it said ISTP rather than INTP is because your Se tested about 1 point higher than your Ne, but that discrepancy is so close your real type should be IxTP. So, do you identify more with ISTP or INTP? ISTP is the Crafter, and INTP is the Architect, both these roles being very similar as in they both involve complex elements of designing prototypes and logical theories. The difference is for ISTP it is more practical, kind of like the INTJ, like being a mechanic, athlete, or operator. INTP is more theoretical, kind of like the INFP, being more dreamy and hands off, like being a thinker, author, or philosopher. I would imagine both ISTP and INTP would make great scientists though, as in it is both a practical and theoretical occupation. Perhaps you even break the laws of MBTI and are both ISTP and INTP, or IxTP!
