I've read carl jung's "psychological types" and von franz's "conscious orientation" and mainly take my sources of the cognitive functions from wikisocion. im extremely accurate in my knowledge and take information from reliable sources, diving very deep into typology. i dont use mbti, as it is bad and just use the jungian system along with socionics to type people. i learn socionics on wikisocion! please make sure to help me learn more if you can! i want to specialize in typing.
