31 Days of Myers-Briggs :: Day 6 Case of Double Personality


I've briefly described the Four Temperaments, talked about what the letters mean, & even delved into the importance of knowing how the Four Types use tools & communication.  I thought it would be good to clarify some of the information, which also gives me a grace day in writing. 

Partly, I would love to hear if you have questions.  Please type them in the comments.  Do you want to know more about something specific in regards to MBTI, please let me know?


In Spring I had put my post on Personality types & a test on Twitter.  Immediately I had loads of people responding with their personality type & saying, "I use to be "X," but now I'm "Y."  I talked about my analysis of nature outweighing nuture in regards to personality, and why knowing who you were as a child is very critical.  However, I want to expound upon the idea that people tested as one thing in college & then later came to found they tested opposite.  You might think you have a double personality, but I would argue that most likely, you don't.  In fact, as I stated in Day 3, we have one personality & for the most part we don't sway from it.  

1. Well, Kamille, I tested as INTJ in college & now I'm testing as INFJ.  Was I one at one point an INTJ & I simply shifted?

  • I would want to know what changed from college to present?  To see that the only letter change was from a "T" to a "F" makes me think that your major or role in college was of such that required you to use more objective decision making; hence, the "T" outshined the "F."  Were you truly an "NT" to begin with or is your role now causing you to utilize your "F" function more? 

I would encourage you to read over the NT & NF and look at the two with a bird's eye view rather than microscopic. Ask yourself:

  • When I look at myself as a child to adolescence to adulthood, do I see one trend over the other. 
  • Did I have a job or major that required myself to respond a certain way over what my gut reaction would be?
  • Were there people affirming less dominant functions in me & I worked hard to become that person?

2. I tested as ENTJ prior to having kids & now I'm testing as ESTJ (or going from an E to an I). How   can this be so?

  • Again, I would recommend taking a bird's eye view to see how you were as a kid, teen, young adult & wherever you are at now.  My mom has taken this test numerous times & came out as something different each time.  I talked her through it & once I said, "what do you see true generally speaking over the course of your life to these questions?"  She discovered that when she tested as an ENFJ was false & is an ESFP.
  • I have also found that many mothers say they are less extroverted as they use to be.  And thus, they answer questions on the test dreaming of being alone (of course you're going to end up an "I" on the test).  It's best not to put much validity in your result if you're running on empty, because most of the "E" questions sound exhausting (even to true extroverts). 

3. What's the best way to take the test?  I always have a hard time answering those questions.

  • Don't take the test when you're tired, hungry, etc. 
  • Take the test when your mental capacity can focus.
  • Answer to who you are, NOT to who you would like to be.
  • Take pride in knowing who you are is GOOD & don't hide from it.
  • Don't spend too much time on the questions & don't overanalyze. 
  • Answer & move on. If you get stuck, pass & come back.
  • Answer thinking over the majority of your life.
  • Ask yourself, "when I was six, when I was 13, when I was 18, when I was 27, etc, was this generally true of me?"
  • Maybe you come up with seeing that your "S" & "N" were fairly close.  Read the description of both to see which rings true to you overall.
  • Again, I cannot emphasis this enough, think back to you as a child. 

If you've taken a test, go back & look at your percentiles.  Read over the general descriptions of the Four Types.  Make a list of how you used tools & communication as a child, teen & adult.
