Groups made up of primarily Delta types tend to be focused on working on projects, enjoying physical recreation, or finding out interesting things about each other. Laughter is usually subdued and brief; instead, people smile a lot and try to be witty and welcoming. Groups need to be focused on some specific productive activity or topic of discussion, or else they fall apart. In Delta groups, there is a lot of splintering and decentralization. This allows for more focused and productive interaction with only those who share your particular interests or sentiments. People jump from small group to small group easily to keep up their interest level. No one demands that the entire group listen to one person or that everyone do the same thing. Delta Quadra types believe that if everyone just pursues their own interests and makes some accommodations for others, the group will be better off anyway. Delta Quadra types do not focusing on building group identity or unity of purpose, but prefer for the group to remain splintered and decentralized.
Delta romantic relationships usually begin simply as the encounter of two individuals interested in a relationship and each other in a particular moment, with very little in terms of outward demonstrations of "romance" in the "wooing" sense of the term or in strong external demonstrations of emotions. Deltas are more focused on the present moment than Gammas, and therefore even relationships of very strong attachment do not lead to constant concerns as to their longer-term practical feasibility. Deltas see as optimal romantic relationships those where partners spend time together on fun activities and sharing ideas of potential practical application. Romantic atmospheres are low-key, based on comfort but practicality.
Perception of Other Quadras
Deltas tend to see Alpha types as fun company and interesting people to discuss ideas and prospects with, but naive and inconsistent in their personal and business relationships. Alpha types seem to lack the common sense to turn their fun and creative energy into something productive and often seem overly idealistic.
Deltas tend to see Beta types as people who "dream big" and always want to turn things into grandiose endeavors, yet can't manage day-to-day affairs effectively. Also, Beta types seem unwilling to consider things from the point of view of others, which gives them a streak of meanness and cruelty.
Deltas tend to see Gamma types as driven and reliable in personal and business relationships, but not sufficiently understanding of people who want to pursue their own individual path in life. Gamma types sometimes become too demanding and can have a streak of vindictiveness or spitefulness which prevents them from being accepting and forgiving.
