1. What are some clear cut differences that you have noticed between each of these types?
2. What are the similarities?
3. What are traits that make you think ISFJ (or ISFP / INFP) right off the bat?
I'm looking more for the differences between females of these types; males are much easier for me to spot. I am having trouble differentiating between these three types and being an INFP myself (and female) doesn't help my lack of understanding. Thanks in advance.
