Starting with the most YIN and moving to the most YANG, one goes from T2, T1, T4 to T3.
Type 2 Water (yin-yin): First with T2, the most Yin, associated with Water in DYT. Paulos associates Water with Curve-Circle types, which means intense gaze (abstract intuition) and yin features showing sensitivity, can be any face shape. The most yin curve-circle is the Possibilitarian, which is in curve circle wave (all yin). They are 1 in 80,000 women, relatively rare compared to some other types. [Next is the Imaginarian, 1 in 90,000, which is the out curve circle wave. The Out quality makes them more extroverted than the usual T2, so they may be 1/2 or 2/1 or even 3/2. The Oracle is also water, but has some yang, particularly in the face shape, so might be 2/4. The Catalyst is water, but so rare you are not likely to be one or meet one.]
Type 1 Air (yang-yin): Type 1 is Yang followed by Yin, associated with Air in DYT. Paulos associates Air with Curve-Box types, which means intense gaze (abstract intuition) and yang features showing objectivity. DYT associates T1 generally with yin features when cute, small and upward, and yang with starpoint features. This is the least possible to line up, as he seems to define this element very differently than DYT does. The most Type 1 appearing type is the Allure, followed by the Dreamer. They are the Out and In line circle wave types. There are 1 in 50 women that are Allures and 1 in 10 women that are Dreamers, so they are very common. [The one Air according to Paulos that could be a "starpoint" T1 is the Trailblazer, 1 in 190,000, so rare you are not likely to be one or meet one.]
