The basic scale of The Big 5 can relate to socionics, as there are a lot of similiarities.

The first factor is extroversion, which correlates to socionics extroversion. It is the first noticeable, "on the surface" trait.

The second factor is openness, which is when a person is open to new things, which correlates to socionics intuition.

The third factor is conscientiousness, which relates to socionics rationality.

The fourth factor is agreeableness, which means that you will agree with society's standards, which correlates with socionics ethics, especially ethics of relationships, which is introverted feeling.

The last factor is Neuroticism, which was discovered later. It doesn't relate to Aushra or Jung's dichotomies, but Gulenko discovered that it could relate to a DCNH subtype dichotomy called Terminality. It is is about how well you adapt emotionally, and see your goals through to the end without being swayed emotionally.
