这段对于自保4、一对一4和社交4的描述节选自Don Richard Riso和Russ Hudson的Discovering your personality type。
1 自保4 Self-Preservation Fours: The Sensualist (Ichazo's "Reckless/Dauntless")
·Self-Preservation Fours focus their envy and hypersensitivity on their concerns about their immediate environment and on their quest for physical comfort. They attempt to deal with emotional issues by surrounding themselves with as much luxury and beauty as they can afford, by indulging in their favorite foods, and by giving themselves "consolation prizes" for their suffering. They might be disappointed about a job situation or a failing relationship, and so stay up late at night drinking expensive cognac and watching a favorite movie. Self-Pres Fours are particularly sensitive to comfort issues--the temperature of a room, the quality of the lighting, the humidity or lack of it, the weather--all produce powerful emotional responses. Self-Pres Fours become frustrated that the environment is insufficiently attuned to their personal needs. Attempts to control the environment and self-indulgence in rich foods, drink, drugs, or other sensual distractions can exhaust Self-Pres Fours, leaving them unable to function well outside of their own narrowing world.

2 一对一4 Sexual Fours: Infatuation (Ichazo's "Competition")
·Sexual Fours focus their envy and hypersensitivity in their intimate relationships. They are perhaps the most emotionally intense type of the Enneagram, which is both their gift and their potential downfall. They possess both a capacity and a desire for profound intimacy, and they derive tremendous insight into human nature through the ups and downs of their romantic lives. They have a sultry, sullen quality that can be attractive and mysterious, or at times, off-putting to others. Sexual Fours pour their energy and attention into the object of their affection, often becoming infatuated or even obsessed, sometimes after only one meeting. Sexual chemistry triggers their powerful imaginations, leading them to create enormous expectations of potential partners. Sexual Fours tend to be drawn to people who possess qualities and talents that they believe they lack. They want to complete themselves by associating or merging with the valued other. But this almost never works, so they may also end up envying and resenting their romantic partner for unintentionally reminding them of what they feel they are missing. In any case, Sexual Fours go through tremendous shifts of feeling about their loved ones--everything from idolization to unbridled hatred. Generally speaking, this type is aware of these feelings, including the dark ones, and finds ways to express them, sometimes in self-destructive ways.

3 社交4 Social Fours: The Outsider (Ichazo's "Social Shame")
·Social Fours focus their envy and hypersensitivity in the social realm; thus, they are people who deeply want to belong, to be a part of an "in crowd" with a glamorous lifestyle, but who often fear that they are not up to it. Social Fours tend to be more extroverted than Fours of the other two instincts and can resemble Twos or Sevens. Social Fours can be quite funny, using droll, ironic humor to make a point or simply to stimulate conversation. They enjoy expressing their individuality and sense of style in a more public way, although they also attempt to conceal the extent of their feelings of social inadequacy or shame. Social Fours may work hard to develop a public persona through which they can communicate the depths of their feelings, but this persona is usually more glamorous and free than they actually feel. Social Fours are acutely aware of the artifice of their persona, but they use it nonetheless as a way of finding some sense of belonging and involvement in the world. When they are more troubled, Social Fours fear social humiliation to such a degree that they may retreat from much social contact, becoming isolated and reclusive. They may also develop a personal style cultivated to show the world how wounded and different they feel.
