Hello! where do you find sources to study personality typology systems? I want to learn it too :>
Hello, I'm glad you asked!
I don't really have solid sources for a lot of things that I ended up learning, mainly because my understanding of typology is subjective, and deductive.
I started with 16personalities.com, and then started reading about cognitive functions. There are a lot of great tumblr authors and reddit users who have an amazing understanding of it, and I think reading and going through those really consolidated my opinion on types.
The most important thing one must understand is that: since we're technically working with a form of pseudo-science (yes, as much as we'd like to think this is valid, mbti and enneagram are pseudo-sciences that are invented by people purely through noting down common behaviors and segregating people based on those basic classifications, without any practical experimentations proving that this is the truth.), there would be a lot of variations in the way people view a type. I think this was something I had a lot of issues with, since every so-called expert in this field had their own interpretation of each types (this is very noticeable with enneagram). I had to narrow down on some of the common/basic features of each type, and then dumb it down for me to understand.
And a lot of it is observing people. Although there are a lot of differences in the a way people with the same type behave, the way they come to conclusions, take in information, and engage with their world is eerily similar.
16personalities - a pathetic, but great start towards typology. A lot of it is crap, since they just put 4 letters, describe your behavior with those 4 letters, and call it the end. I think this is important, because it introduces you to the rabbit hole, gives you an idea of what typology would look like if you just looked at a person's behavior.
Once you understand I , E , N , S blah blah from 1., get into cognitive functions. Some really good (infact amazing) resources for the same are:
Funky Mbti in Fiction: https://funkymbtifiction.tumblr.com/
Mbti Notes : https://mbti-notes.tumblr.com/
You can search up Books on mbti cognitive functions as well. I didn't since my ADHD brain would die if I'd have to read so much theory that makes you feel like you are a part of a cult.
Note: You have to formulate your own understanding on what is right, and what isn't, since a lot of the information, as previously mentioned, are subjective understanding of the user. Reading through all their posts, their type deduction method, and finding a relation irl was the most helpful way for me to understand cognitive functions.
3. OBSERVE. TYPE. FAIL. I cannot stress how important this is. If you want, you can start by typing everyone by the 4 letters seen in 16personalities. You'll develop a superiority complex, that'll quickly fade once you get into cognitive functions. Compare and see how different your 4 letter typing is from cognitive function typing. Regret your ideas, and concepts. Repeat it.
After a significant amount observation and failed typings, you'll start to notice a pattern in how every cognitive function would look like irl.
For example: anyone with a dominant Ne (ENFP, ENTP) will play around with ideas. They breathe ideas.
Fi users will not budge from their internal morals (which can be extremely irrational)
Fe users will never give up on the collective emotions of the group.
TYPE FICTIONAL CHARACTERS. I personally find this to be a lot easier than real life characters, since fictional characters are very 2 dimensional in the way they think.
You might get stumped in this process. Very natural. How the hell are you supposed to be sure when you type someone. You might even hate yourself and might end up giving up. It's okay. Just go back to step 2, review everything and then start typing again.
4. Ask questions. As someone who's scared to ask questions, I love reading the stupid, yet relatable reddit questions. Helps you understand and correct your typing technique and method (there's no way you're going to be a genius and type people immediately by the cognitive functions they use. You'll be surprised by how many experts accidentally end up typing by behavior.)
5. After you're confident about yourself, and your typing technique, it's time to hate! Open up personality database, and start searching up your characters. Open up the comments. Look through them. Read through them to see supporting statements or insights on whether the character is right or not. If you like arguing with people on the net, that is a great place to do. You can also inflate your ego, looking at people mess up typing because they start bringing unreasonable relations which don't even make sense.
Oh, oh did I forget tumblr, reddit, and other site users? It's time to hate on us as well.
6. Once you've completely exhausted a typing technique, move on to the next one. Start seeing the variations, try to understand how this typing technique is different from the previous one. Shit on it if you think it is unreliable. Steps 1-5 would remain the same for every typing technique.
I just realized I rambled. So much.
Bother your friends to discuss this with them. Playing around with ideas, someone openly questioning me helped me a lot. Some might shoo you away. But some would definitely be interested.
Google Search whatever you want to know by adding the typology that you are trying to study. eg: "cognitive functions mbti", "Why are enneagram sx5s so annoying reddit"
Have fun. This is a very tedious process. And not for everyone. So take breaks if you think it's too much. Don't pressure yourself to understand everything. Sometimes it clicks. sometimes it doesn't.
Typing human beings is hard. You'll soon realize how unaware almost everyone is. People will say they are INFP when it's very clear that they are ISTJ. You'll also realize how unaware you are, when you start typing yourself.
Any form of trauma would change the way a person uses their functions. Which is why it is very very important to not type people by their behavior.
People will hate you for boxing them. No one likes to be told that they're an enneagram 5, who has trouble opening up, or sharing any form of resource with another person because they haven't had their needs met as a child, and were forced to come to a conclusion that people outside would never meet them, and hence it is useless to depend on them, and it is better to find a way out by yourself.
If you ever get too deep into this, step out of it, and view humans as humans.
Create a blog. Make posts. If you think your posts where absolutely wrong, update them, change them, and rework on your knowledge. I started this blog as a diary for whatever I've learnt. Or have an actual book to write things down >< .
