Socionics is a personality theory which is focused on 8 different functions: Ti (introverted thinking), Te (extraverted thinking), Fi (introverted feeling), Fe (extraverted feeling), Ni (introverted intuition), Ne (extraverted intuition), Si (introverted sensing), and Se (extraverted sensing). These functions are ranked based on how much they are valued and their strength. Thinking types are logical (L), and feeling types are ethical (E).
Examples of types:
LII (Logical intuitive introvert), (Ti-Ne)
ESE (Ethical sensory extravert), (Fe-Si)
SEE (Sensory ethical extravert), (Se-Fi)
ILI (Intuitive logical introvert), (Ni-Te)
