Delta Quadra
ESTJ, ISTJ, ENFP, INFP
Te-Si, Fi-Ne
Positive personal experience (Fi), comfort-seeking (Si), perspective ideas (Ne), logical use and management of resources (Te).
Focus on projects, enjoyment, and discovery. If groups are formed, they are for an ultimate cause, and preference for splitting and decentralization into small groups for more productive interaction. People may jump from group to group and there is no demand for homogenity within groups. Belief that everyone should pursue their personal interests and allow others to do the same. People are welcoming and smiling, but no intentionally collective effort to maintain an atmosphere. Talk about rationale behind actions, emotionally open, and dislike feeling put on the spot. Assume will have to rely on self to achieve goals, not group or luck. Prefer peaceful activities that refresh inner world and contribute positively to outer world. Optimal romantic relationships based on having fun together and sharing practically-applicable ideas.
Regard Alpha as fun company but overly idealistic and struggling to channel positive energy into productivity.
Regard Beta as big dreamers but struggling to manage the day-to-day, and unwilling to consider others' viewpoints.
Regard Gamma as driven and reliable but not understanding or forgiving enough and too demanding.
Okay, that's my summary.
