(aka - The Quadra Wheel)
Types naturally lead into each other, from static to dynamic (alpha NT --> alpha SF, etc.).
The first type of the quadra is the most reluctant to move forward, they get caught up in the spirit of their own quadra and the security of the previous quadra.
The fourth type of the quadra is the most progressive, encouraging change and trying to gain acceptance by memebers of the succeeding quadra.
Each type aspires to be recognised by its supervisor, and may take on aspects of their supervisors quadra (ENTp is a fairly Delta-ish Alpha, ESFj is fairly Beta-ish). This trend greatly influences the orientation of types.
THE WHEEL OF SUPERVISION
Relations of benefit weakly influence the orientation of types. They follow the same directions as relations of supervision.
