Ok, I know that the types most similar to each other are based on cognitive functions and all of that, and I know that changing just one letter of your type doesn't make another type automatically really similar to yours.
But this isn't that serious of a thread, just something I'm curious about: What do you think about each of the four types that are the same as yours except one of the letters is the opposite? You can say anything you want about each of the four, but maybe you could say which one you like or relate to the most and which one you like or relate to the least. I was just curious about how different people view the each of those types.
So for me, since I'm ISFJ:
ESFJ: I actually don't know any sure-fire ESFJ's, though I think some co-workers of mine are ESFJ's. I always picture ESFJ's as very motherly types...the co-workers I know are female a good bit older than me. I think ESFJ's are really good at making me feel comfortable and setting my mind at ease....they're really good at taking over a situation where I don't know what to do. However, I don't think I would like them as friends much...probably too over-whelming for me. I think I relate to them the least out of the four.
INFJ: I only know one sure-fire INFJ, and she's a really good friend to me. I feel so comfortable opening up to her and telling her any problems I'm having, or personal things about myself. She's actually very similar to me, though more dreamy and a deeper thinker than I am. But even though they're kind of mysterious to me in a lot of ways, I really like INFJ's and they're very calming to me.
ISTJ: Since ISTJ's share the same Si dominant function as ISFJ's, I naturally relate to ISTJ's very well. My mom is one, and I'm extremely close to her. I also get along really well with the ISTJ's on this board. They may be a little colder and more reserved than me, but they're friendly enough and I love their simplicity. It's funny, because usually I feel like the thinker/feeler difference is the biggest one for me and thinkers usually intimidate me. But because we have so much in common, I think I actually understand and relate to ISTJ's the most out of the four.
ISFP: Unfortunately, I don't know any ISFP's in real life, only one online ISFP friend. But from my experience I really like ISFP's! They're like me, but just more relaxed and fun loving. Still very calm, quiet and sensitive, but not as uptight as I am. The only problem is I feel like they're so mysterious and hard to pin down, and like I said, I just can't find them!
