It'd be hard to convince me that you're not an NJ type, and it seems clear you're an introvert, so I'm confident that you are an IN_J of some sort. I lean toward F rather than T for you, but I also wouldn't be surprised if your preference on that dimension was better described as middle-of-the-road (INXJ) rather than F or T.Tho with an open floor rather than INTP vs INTJ, which type do you think I likely am?
