I did a lot of research on differences between infp and infj (which is like isfj (isfj and infj both have fe and I explain the differences a lot below, but I think this is ok. Infp fits madoka more if you have a read of this. Infj has been typed for her too)
This is just my observation.
Infj tend to tutor infps. Think yoda (infj) who tutors luke skywalker (infp). Yoda only starts fighting when he knows he's just needed. Luke runs into the battle right away to help. To compare them look at disney princesses. Disney did their own chart: pocahantus infj and belle from beauty and beast is infp. Infp when extremely healthy can come off as having fe but really they are fi. Madoka kaname is infp but she has confused people with her well developed fe. She obviously is an infp from other angles though.
i think with infj all you gotta look for is wisdom beyond their years or they pretty much see what is going to happen before it happens coming off as psychic.
infj are trying to advance others and society while infp are trying to advance themselves and others. (Madoka has done the latter and not the former)
infj like to help people for the sake of helping others while Infp like to do things because it's meaningful (unless someone's crying or dying obviously xD). (Madoka has literally contemplated the latter with Kyubey)
Infp are more true to themselves. Infjs tend to blend in and just agree with everything their friends say.
Infj tend to care about balance in the atmosphere and what people think of them. Infp tend not too. (They do want balance but they won't change who they are).
Infj fo come off as gentle, elegant and serious. Infp come across as clumsy, quiet and cautious. (With strangers). (Madoka is not elegant and serious. She is cute and clumsy)
Infp think about how they would feel in a bad situation and take time to process what's going on while infj just know right away. (She took forever to process the problems that was going on). An fe user would just understand right away).
Infp more fixed in their ideals and beliefs. Infp do get hurt easily but easily forgive. and won't roll over when someone tries to attack them if they're on their last legs. They never forget their own problems and go straight back to their own right away after helped a friend (they'll always stick to their ideals even when helping a friends. If it goes against their code they'll just leave).
Infj are fixed in their ideals but tend to be more secretive about them. With friends they can roll over and get lost in their friends problems forgetting their own.
Infp and Infj have similar ideals when both healthy but proceed with it differently. infp get it done right away cuz people are getting hurt. Infj will wait for when they're trully needed. (Now this may confuse people. She didn't actually wait for when she was truly needed when she was needed that was literally the moment that she figured out what she needed to do)
Infp are more about suggesting things than convincing people. Infj may be a bit more forceful with their morals. Infp: what if it was like this? / Infj: it shouldn't be like this. We need to find a way to make it better now.
infp are all for being themselves to inspire others while infj are all for helping others and encouraging them to do better. (She does not blend in to help people like an infj does. She stands out very much).
infp tend to be more artistic and creative with their minds off in lala land than Infj (Infj do this too but Infp do it extremely).
Infj x Infp tend to be the heroes in situations in reality/fiction (when Infp get their butt in gear anyway). Infp tend to die winning in a good cause. They tend to be martyrs and will fight a a cause on their own not caring if others join either you follow or don't.
Infj tend to encourage people to help them out and likes to have the globe working together to succeed in a cause if they can. (Martin Luther king is a wonderful Infj example). (Pretty much madoka decided to bare the burden on her own instead of asking for help like an fe user would).
Infj is fe. Infp is fi.
Fe often comforts other people. It knows what to say, to make things okay, or at least reassure them that they are not alone. Fi often acts to help other people. It knows what to do, to make things okay, and it never acts as if it understands when it doesn’t – it just offers support. (Link to website below for where got this sentence). (When sayaka and Homoura broke down crying she did not sugar coat things to make them feel better she left because she felt uncomfortable with their ray of emotions)
That is, really, what identifies Fe, the mentality of “WE are in this TOGETHER.â€
Inferior Fi becomes hissy and self-contained; they feel misunderstood and wronged. Inferior Fe lets people have it, bursts into tears, and sometimes gets violent.
Fi is less reluctant to judge someone else’s behavior, because Fi believes that ethics are all internalized and subjective to self. So FPs are very much “do what you want†in a sense, and reluctant to judge others harshly Fe has no problem judging other people as wrong or immoral, because its’ ethical consensus is external and objective. It’s obvious that this behavior is wrong, and to call it anything else would be inappropriate. (Throughout thing she wants everyone to be friends and does not completely judge them like an fe user would which is isfj and infj)
this is when Infp and Infj are unhealthy: Generally, I think it all comes down to motivation. Fe often manipulates with the intention of shaping someone else into being exactly like they are, or out of a joy at provoking an emotional response. Fi manipulates for specific reasons and/or the desire to control other people.
Character mention who is infj: kenshin himura
I didn't write this part onwards someone else did. The website link to them is on my quotev page with this writing posted.
INFp's Extroverted Ethics will give them the impression of being very warm, friendly, and emotionally open people. They'll likely jump at the opportunity to say hi to you (if they know you, that is), and will ask all sorts of questions about you and your emotional life in casual conversation. [s:c079b6b36d]They have strong morals, but their Introveted Ethics is considerably weaker than their Extroverted Ethics, leading them to sometimes sacrifice principle to achieve desirable relations with others.[/s:c079b6b36d] (I'm rethinking this concept. My moral system may be more focused on outward treatment of others). Still, I've made some significant Introveted Ethics blunders in my life that I still can't stop thinking about, even to this day.
INFj's Introveted Ethics will give them the impression of being very moral, ascetic beings. They are kind and approachable, but unlike their bubblier INFp counterparts, they radiate a seeming sadness and seriousness. They value self-sacrifice, loyalty, steadfastness, and principle. Their Extroverted Ethics is considerably weaker than their Introveted Ethics, making them seem cold and unfeeling at times. I once asked about an INFj I knew, "is she as mean as she looks?"
INFp: Extroverted Sensing dual seeking
INFj: Extroverted Logic dual seeking
INFps crave adventure and stimulation. They love exciting, novel atmospheres in which they can meet all sorts of new people and have all sorts of new experiences. I, for one, can't get enough of road trips
. They can also be very sexually adventurous and rebellious despite seeming modest at first. They are also very spontaneous and love doing things on the fly.
INFjs crave atmospheres in which they can discuss their values and other topics of intellectual interest with close friends. They're often serious, religious (if not observantly religious, philosophical) people who value stability and self-improvement. In defense of my fellow INFps, we are also very serious and value intellectualism and self-improvement, but not to the degree which INFjs do.
Lastly
INFp: Extroverted Logic POLr
INFj: Extroverted Sensing POLr
INFp's Extroverted Logic POLr manifests itself in their lack of organization and difficulty with business matters. Anything involving economics, bureaucratic paperwork, applying for jobs, etc. is anathema to INFps. They can do it when they apply themselves, but it will never be natural or enjoyable for them.
INFj's Extroverted Sensing POLr manifests itself in their aversion to change, squeamishness about health, and dislike of rough humor. They're also very sensitive to their physical surroundings. I'm probably missing a lot of things when I discuss the Extroverted Sensing POLr, but in essence its much more than being unathletic or tripping over things (I actually know some very athletic INFjs).
INFj anger seems to be more of a 'righteous' anger, e.g. about global issues, or whether someone has acted improperly etc. - INFps on the otherhand, don't like people telling them what they should make of their lives etc. (She told Kyubey to get lost for telling people and herself what their life's are. Live stock).
Best characters to look at for infp is N for males and sara crewe for females.
