Self-Preservation: The focus here is easy to understand from the name. People of this Instinctual type are preoccupied with basic survival needs as they translate in our contemporary society. Thus, Self-Preservation types are concerned with money, food, housing, health, physical safety, and comfort. Being safe and physically comfortable are priorities. These people are quick to notice any problems in a room such as poor lighting or uncomfortable chairs, or to be dissatisfied with the room temperature. They often have issues connected with food and drink, either overdoing it or having strict dietary requirements. In the healthy to average Levels, of the three Instinctual types, they are the most practical in the sense of taking care of basic life necessities—paying bills, maintaining the home and workplace, acquiring useful skills, and so forth. When these types deteriorate, they tend to distort the instinct to the degree that they are poor at taking care of themselves. Unhealthy Self-Preservation types eat and sleep poorly or become obsessed with health issues. They often have difficulty handling money and may act out in deliberately self-destructive ways. In a nutshell, no matter what Enneagram personality type is involved, Self-Preservation types are focused on enhancing their personal security and physical comfort.

Social: This variant is focused on their interactions with other people and with the sense of value or esteem they derive from their participation in collective activities. These include work, family, hobbies, clubs—basically any arena in which Social types can interact with others for some shared purpose. The instinct underlying this behavior was an important one in human survival. Human beings on their own are rather weak, vulnerable creatures, and easily fall prey to a frequently hostile environment. By learning to live and work together, our ancestors created the safety necessary for human beings not only to survive but to thrive. Within that social instinct, however, are many other implicit imperatives, and primary among them is the understanding of "place" within a hierarchical social structure. This is as true for dogs and gorillas as it is for human beings. Thus, the desire for attention, recognition, honor, success, fame, leadership, appreciation, and the safety of belonging can all be seen as manifestations of the Social instinct. Social types like to know what is going on around them, and want to make some kind of contribution to the human enterprise. There is often an interest in the events and activities of one's own culture, or sometimes of another culture. In general, Social types enjoy interacting with people, but they avoid intimacy. In their imbalanced, unhealthy forms, these types can become profoundly antisocial, detesting people and resenting their society, or having poorly developed social skills. In a nutshell, no matter what Enneagram personality type is involved, Social types are focused on interacting with people in ways that will build their personal value, their sense of accomplishment, and their security of "place" with others.

 Sexual: Many people originally identify themselves as this type, perhaps confusing the idea of a Sexual Instinctual type with being a "sexy" person. Of course, "sexiness" is in the eye of the beholder, and there are plenty of "sexy" people in all three of the Instinctual types. Furthermore, lest one think this type more "glamorous" than the other two, one would do well to remember that the instinct can become distorted in the type, leading to the area of life causing the greatest problems. In healthy to average Sexual types, there is a desire for intensity of experience—not just sexual experience, but any activity having a similar "charge." This intensity could be found in a great conversation or an exciting movie. Much has been said about this type preferring one-on-one relationships versus the Social type's preference for larger groups, but a quick poll of one's acquaintances will reveal that almost all people prefer communicating one-on-one rather than in a group. The question is more one of the intensity of contact and the strength of the desire for intimacy. Sexual types are the "intimacy junkies" of the Instinctual types, often neglecting pressing obligations or even basic "maintenance" if they are swept up in someone or something that has captivated them. This gives a wide-ranging, exploratory approach to life, but also a lack of focus on one's own priorities. In their neurotic forms, this type can manifest with a wandering lack of focus, sexual promiscuity and acting out, or just the opposite, in a fearful, dysfunctional attitude toward sex and intimacy. Sexual types, however, will be intense, even about their avoidances. In conclusion, no matter what Enneagram personality type is involved, Sexual types are focused on having intense, intimate interactions and experiences with others and with the environment to give them a powerful sense of "aliveness."
