Anyway, I'd just like to state that I'm not an expert on this, so take my words with a grain of salt and feel free to correct me if you see something that is incorrect. Spoiler: What is MBTI? MBTI is a theory developed by Katharine Cook Briggs and her daughter Isabel Briggs Myers based upon the works of Swiss psychiatrist Carl Jung describing how people perceive the world around them and make decisions. It is often described as a personality theory, and it can be simplified that way but I believe it can go deeper than that. A person's type indicator is a 4 letter code where you have 4 pairs of traits that can be put together to form this code. These traits are as listed: Extroversion/Introversion, iNtuition/Sensing, Thinking/Feeling, and Perceiving/Judging. For example, someone with the traits Extroversion, Sensing, Feeling, Judging would be an ESFJ and the opposite would be an INTP. However, one thing I would like to note is that everybody has all the traits, this just measures whichever a person uses more. Although these may change, (and this is a big part of where MBTI criticism comes from), the cognitive functions (2 big words that means how you prefer to see the world; more info is in the "Cognitive Functions" spoiler) are supposed to remain more or less the same. The Cognitive Functions are 4 pairs of ways of seeing the world. Everyone uses them all, but the top 4 are the only ones shown. The rest are known as the "shadow functions" and aren't used much. These pairs include Introverted iNtuition-Extroverted iNtuition (Ni and Ne respectively), Introverted Thinking-Extroverted Thinking (Ti and Te), Introverted Feeling-Extroverted Feeling (Fi and Fe) and Introverted Sensing-Extroverted Sensing (Si and Se). For example, an INTJ would have the cognitive functions Ni-Te-Fi-Se. This means they primarily use Introverted Intuition developed early in childhood, and then begin using the other functions as they grow and develop. TL;DR: MBTI is a theory with 4 trait pairs and 4 pairs of "cognitive functions" that determine how people see the world and make decisions.

You can also see it as a theory with soft science behind it. Either way, it's still useful to some people. Let's find compromise and agree that it can be useful, but it's unwise to take it too seriously. "MBTI is unreliable" - MBTI types are not supposed to change. The tests may often give different results, but that's the fault of the test, not the theory. "Neither Myers nor Briggs had a psychology degree" - So? Michael Faraday received little formal education and he invented the electric motor. More reading on debunking the debunking (lol) Spoiler: The Cognitive Functions There are different ways to describe them, but here are a few. The cognitive function locations are known as dominant-auxiliary-tertiary and inferior. For example, an INTJ's Fi would be their tertiary function. And here is the list of functions for each type in order: Spoiler: How to find out your type Now we're getting to the fun part! Now after learning about the MBTI and the cognitive functions, you can start by looking at charts and seeing what each of the types are like. (Although many of these tend to call it a personality theory, it can be thought of that way but it's best not to think of it like that) Now that you know what the types are like, you may look at the functions and see which ones are relatable. Since most of you guys are around adolescent age, it may be harder to type but it's still possible. Try picking out the top 2 most relatable functions and this should be enough to give you the rest of them. However, some people (like me) find it hard to find which cognitive functions are the most relatable, so in that case: you may take a test for it as seen here. After this test, it will recommend you a type. Even then, you may still be confused. In that case, look at the questionnaire below and try to answer as truthfully as possible, and I can try helping you find your type. Spoiler: MBTI Questionnaire Use this and people may try typing you based off of it. • How old are you? What's your gender?

Do you think authority should be challenged, or that they know better? If you do break rules, why? Note: I ripped this off from /r/mbtiTypeMe so you can ask them if you may choose so as well. Anyway, I hope you enjoyed reading that! My type is ISTJ and I'm open to suggestions or answering questions you may have! There are active communities for MBTI on websites such as reddit and tumblr and they often like to post memes and videos on the subject. I'm a decently big fan of it and I hope someone else can find enjoyment in it too!
