I was sitting with my INTJ boyfriend the other day, and reviewed this list with him. I started reading the sensing and intuitive list first, and said, "So, I'm concrete, you're abstract. I'm realistic, and you're imaginative. I'm practical, and you're conceptual. I'm traditional, and you're original." He turned to me and laughed and said it sounds as though they're mixed up, because the list for him sounded more like me and vice versa. When considering how Se works compared to Ni, it really is the case. As Se is closer to Ne and Ni is closer to Si.
However, I would even go on to say the same for feelers that are introverts, and how they may seem more extroverted due to feeling prompted to reach out to others, and being initiating. And so forth.
Lists like the above just don't quite work. When presented with such, I can see how many people mistype their selves. Being in a liberal arts department of a university, I know many people who are mildly familiar with mbti and have taken assessments, or self assessments. And a fair about of ISFP's I know have mistyped their self as ENFP's and INFP's and even INFJ. An ESFP mistyped himself for an ISTP. And etc. However, I think I've seen more confusion amongst ISFP's I know in real life. I'd like to say it's due to the spontaneity and artistic aspect of the ISFP that pulls them towards words like, "Imaginative," and makes them believe themself to be Intuitive rather than Sensing.
