Next is intuition vs sensing. Do you prefer doing hard work or hard thinking? I had a better question for this, but I forgot it. :S
Hard work would be doing tedious math calculations, or working at a factory doing one task all day.
Hard thinking would be finding the answer to seemingly impossible questions, or coming up with policy.
Here is the difference between who I believe is ISFP and myself, INFP in behavior.
My evidence is in my brother. Hates talking about anything that requires thinking. Often cites that he was never taught this in class. Well, I do believe knowledge of at least basic geography, like where all the important nations are is important. He didn't know where France was. He does do better in school though. Our work habits are different. I procrastinates, and he doesn't. He hates going to the gym, but can do more than I can on an average, and I go more often then he does. It is a difference between 50 and 70 sit ups, which is sad considering our age difference. He also is REALLY good in math, much better than I am, because he actually does the work. Draws differently as well. Draws things he can see. I draw what I want to draw, but imperfectly. He draws much more accurately than I do. Wants to be an artist. Pretty sure anything theoretical would be a stupid choice for him. ISFP.
