So I have a friend who insists she's an ISTJ but my ENTP husband and I agree she's an ISFJ. I've studied MBTI for nearly four years and am passionate about while she's read it for an hour. See, the problem is she is mixing up "emotions" with feelers when I tried to explain to her that that has nothing to do with feelers vs thinkers. She insists she's uncomfortable with peoples feelings and that she's not overly emotional. She also claims to over analyze everything which makes her a "T".
But the evidence points to her being ISFJ - she's volunteers 70hrs a month, brought me soup after my surgery, has taken care of an ill woman for a month at her home, etc.
I opened up "Gifts Differing" by Isabel Briggs Myer and read to her the differences of F vs T..... At the end of our 45 minute discussion she said "Are you mad? I don't want you to be sad or mad at me for talking about this so long. I am open minded to re-take the test." I asked, "Why would you care if I was sad or mad? Only a feeler would care to that extent."
You see, I think that many ISFJs can be mistaken for ISTJs because of their loyalty to authority and rules. Consideration/Loyalty for rules and authority can override people/relationships at times which may make the ISFJ appear heartless or cold.
Even my ENTJ father-in-law who used to teach MBTI in the military was mistaken for his wife to be an ISTJ but really she's an ISFJ (who readily agrees to this).
.... anyway what are some stark differences that you guys notice between you ISFJs and ISTJs? Did any of you guys mistaken yourself for ISTJ then later realized you were an ISFJ?
Thank you for your help! :)
