You know you’ve done it, or at least thought about it. You’re up late, can’t sleep, so what do you do? You read, you watch Netflix or take silly personality tests online to try and figure out more about yourself (or see how accurate said test is or not). No? Just me?

Well, personality typing has become popular over the years especially now with easy access to test taking online. Without a doubt, one of the most popular systems belongs to the MBTI, better known as the Myers-Briggs personality test. Not only is it used for personal reasons, but many professional companies use it as well. The assessment is based on the research and ideas of Carl Jung, Katherine Briggs, and Isabel Myers so it’s not without merit (though of course, its validity will always be in question).

So what then is the test all about? The theory argues that each individual has a preference for Extraverted or Introverted, Sensing or Intuitive, Thinking or Feeling and Judging or Perceiving. You also show a preference for cognitive functions (IE: Introverted Sensing).

When you break it all down, that creates a possibility of 16 different Personality Types. There are various tests you can take (professional is always best) to try and figure out your type. A good place to begin is with the Myers-Briggs/Jung Typology Test from That said, this will probably only work as a narrowing tool because it’s harder to figure out true type without the help of a professional.

After a lot of research and test taking I was able to (“I think”) figure out my type. Mostly I was stuck somewhere between an INFP and an INFJ, but eventually, I leaned more toward INFP. Autumn, also a writer and a moderator of this site, is an INFJ. So identical twins: one of us an INFP and the other an INFJ. A little bit like Jane Eyre (INFP) and Helen Burns (INFJ) as children.

Watching the 1983 adaptation of Jane Eyre, Helen and Jane were like exaggerated versions of us. Rebecca, the other writer and moderator on this site is also an INFJ in many ways quite a bit like Rory Gilmore (no surprise the three of us came together to make this site).

Which brings me to the point of this whole blog post! After much research over the years, and having attempted to type everyone in my immediate family, I decided to now take it one step further in trying to type fictional characters. Why do you ask? Because it’s fun! Not only that, it gives you good insight into characterization.

Of course, typing fictional characters isn’t an exact science. Personally, I think there are many characters that are frequently mistyped. You’ll notice on my photo slider featured below that I type Hermione Granger of Harry Potter as an INFJ. Most people will type her as an INTP or an INTJ. So why then do I disagree?

Well for one, just because someone is an intelligent thinker doesn’t mean they are a “T.” INFJ’s are the rarest of the types (it’s pointed out how singular Hermione is). Not only that, J.K. Rowling claims Hermione is a lot like herself (and Rowling is usually typed as an INFP or an INFJ).

This quote comes directly from J.K. Rowling about Hermione:

“I have often said that Hermione is a bit like me when I was younger. I think I was seen by other people as a right little know-it-all, but I hope that it is clear that underneath Hermione’s swottiness there is a lot of insecurity and a great fear of failure (as shown by her Boggart in ‘Prisoner of Azkaban’).”

It’s Hermione’s over the top, even illogical attempt to save House Elves that make me think she’s more of an F. S.P.E.W. has INFP or INFJ written all over it. Hermione chooses this oftentimes ridiculed crusade because it’s right not because it’s logical. Typically a “T” person might see her crusade as pointless because it won’t actually go anywhere.

At the end of the day, Hermione is all about her ideals. Though I think she’s difficult to type because she’s somewhere between logic and feeling. Sometimes she even points out how she has a bad feeling about something. Personally, I see her as a character that uses Introverted Intuition (Ni) before she uses her logic (and she does) which happens to be the dominant function of an INFJ. Just because some INFJ’s are stereotyped to be mystical or psychic doesn’t actually mean they all are. What most of them are, however, are the “champions of the oppressed and downtrodden.”

There is actually a lot of misunderstanding out there about “how” to type. Real typing comes down to cognitive functions rather than Extroverted vs Introverted or Feelings vs. Thinking and so on and so forth. How to tell a true personality is to look at the functions.

The functions are as follows:

Extraverted Sensing (Se)

Introverted Sensing (Si)

Extraverted Intuiting (Ne)

Introverted Intuiting (Ni)

Extraverted Thinking (Te)

Introverted Thinking (Ti)

Extraverted Feeling (Fe)

Introverted Feeling (Fi)

Everybody has a dominant function, an inferior function, etc…and that is how you truly figure out your personality type. Besides the link for the test above, this cognitive functions test is also a good narrowing tool.

That said, it’s one thing to figure out your own type, it’s quite another to figure out a fictional character’s. You might have one interpretation, and then someone else will completely disagree with the said assessment. It’s all theory and interpretation.

Another character I believe to be mistyped frequently is Rose Tyler of Doctor Who. There’s a lot of argument for her being ESFP which I just don’t see at all. She’s much more INFP. She’s an idealist, clever and extremely empathetic but she can also be very selfish because she goes so much inside her own head.

She appears to be extroverted when she’s with the Doctor because she is at ease with him. At the party in episode two for instance when she’s still uncomfortable she leaves the party to sit in a room alone. She needs her time to get away and think.

Also, she’s the Belle of Doctor Who who sees the beauty in the “beast.” No doubt Belle is the ultimate and most obvious INFP out there if you will. Take a look at the episode, “Dalek” for instance.  Not to mention Rose’s narrative is driven mostly by her introverted feeling which is the dominant function of an INFP. INFPs can be witty and talkative and can love talking to people. This love of talk comes from empathy rather than being a social butterfly. Describing an INFP from, they say:

“In INFP eyes, even the most revolting person will have something worthy of respect or, at the very least, sympathy.”

Some of the types were harder for me to find, while others were easier to fill. So I’m sure I’ll be adding to these lists in the future. I did attempt to type the majority of the main characters of Doctor Who, so you should see most of the bigger characters included. On top of that, I typed many different characters from TV, film, and literature. Anyway, based on research as well as my own theoretical interpretations these are how I type the characters (feel free to disagree!).
