There is a thread of the three subtypes of seven according to Riso & Hudson here but I'd like to post Chestnut as she elaborates a little more. You can buy her book here.
The Three Sevens each represent a different way of expressing or responding to the passion of gluttony. The Self Preservation Seven finds security through a gluttonous search for pleasure, satisfying opportunities,
and cultivating a network of allies. The Social Seven expresses a kind of anti-gluttony by being of
service to others. The Sexual Seven channels gluttony into an idealistic search for the ultimate
relationship and the best imaginable experiences.
The Self-Preservation Seven: “Keeper of the Castle”
Self-Preservation Sevens express gluttony through the formation of alliances. They typically collect
around them a kind of family network, in the sense of banding together with trusted others and
creating a good “mafia” or partisan group through which they can get their needs met. They rely
mostly on those they trust. These Sevens create a kind of surrogate family of people they value—a
family in which they typically occupy a privileged position.
These Sevens are very practical, good at networking, and skilled at getting what they want and
finding a good deal; they tend to be opportunistic, self-interested, pragmatic, calculating, and clever.
They readily recognize opportunities for creating an advantage for themselves. In this way, Naranjo
explains, gluttony expresses itself in the Self-Preservation Seven in an excessive concern with making
a good deal at every opportunity.
Self-Preservation Sevens always have their nose to the wind for good opportunities. They find
ways to get what they need and want, and they have an easy way of finding pathways to making things
happen for themselves—whether it’s finding the right people, the most advantageous connections, or
a fortuitous career opportunity. They have their ears to the ground and are socially adept.
These Sevens make business connections and network easily because they are alert and mindful to
the opportunities that come along that can support their survival. They hold the position that if you are
not alert to opportunities, you will lose out. This Self-Preservation theme is expressed well in the
proverb “The alligator that sleeps becomes a bag.” There’s an element of self-interest in the alliances
the Self-Preservation Seven makes that may or may not be denied by (or unconscious in) someone
with this subtype. Naranjo says there is a kind of reciprocal interest in these relationships, expressed
in the idea that “I will serve thee, and thou will serve me.” On the low side of this kind of
arrangement, an element of corruption can be present.
Stylistically, Self-Preservation Sevens are cheerful and amiable, with traits that resemble a
hedonistic, “playboy” or “playgirl” type. They tend to be warm, friendly, and talkative. (They love to
talk.) They can express a kind of greed and impatience that reflects their desire to consume as many
pleasurable experiences as possible; they want to eat everything. They expend a lot of energy on
controlling everything, handling things without being noticed. And most of the time, they get away
with getting what they want.
The dominant traits of the Self-Preservation Seven subtype stand out as a love of pleasure and a
self-interested focus on getting what they need to feel secure. In seeking security, however, they can
often confuse desires with needs. These are people who usually feel a need to have a lot of resources,
including money and other supplies that support survival, and they may panic if they feel a sense of
According to Naranjo, the three main fixations of the Self-Preservation Sevens are strategy,
rebellion, and isolation, though it may be hard to see these characters as isolated because they tend to
be very popular. But their strategic and mental nature, together with the prominence of their selfinterest,
can isolate them from others at a deeper level.
Self-Preservation Sevens cultivate a sense of being kind and generous—they like to feel that
everyone depends on them. They may feel omnipotent and they may sometimes use people. They may
also feel that normal rules don’t apply to them—that for them, there is no law, and they can do what
they please. This kind of assertion of their freedom and their ability to do whatever they need to do to
support their self-interest helps them feel safer in the world.
Self-Preservation Sevens’ desire for pleasure and hedonistic self-indulgence can sometimes be
seen as a kind of retroactive compulsion to return to the womb—they dedicate their lives to the
pursuit of a kind of primordial or utopian paradise state of perfect pleasure. In pursuing positive and
stimulating experiences, they may use sex, food, and drink as an escape from the more difficult parts
The Self-Preservation Seven and the Sexual Seven should be easy to tell apart, as they represent
two opposite ends of a continuum, from pragmatic and materialistic (Self-Preservation) to idealistic
and ethereal (Sexual). The Self-Preservation subtype is more earthy and sensuous—more gluttonous
in the literal sense of the word—while the Sexual Seven is more “heavenly” and enthusiastic, more
“upward-looking” in terms of both positivity and high ideals. While both of these two characters
focus on distinct kinds of excess, the Self-Preservation Seven is the most sly, cunning, and pragmatic
personality among the Sevens, while the Sexual Seven is more of a light-hearted enjoyer.
In contrast to the Sexual Seven, the Self-Preservation Seven is not so much idealistic as they are
cynically distrustful. They’re not gullible people who are easily hypnotized (as the Sexual Seven is);
they are more practical and concrete. The Self-Preservation Seven is the most astute and strategic
character of the three Seven subtypes. They may display elements of Type Six in that they can at times
be fearful or even paranoid, though this is not their regular mode. And perhaps paradoxically, the
Self-Preservation Seven is more actively flirty, seductive, and sexual than the Sexual Seven, who
often focuses more on an imagined, idealized kind of communion than actual sex. While the SelfPreservation
Seven character resembles a “playboy” or “playgirl” type of person—an enjoyer of
food and sex—the Sexual Seven can be content with the perfume of things.
Self-Preservation Sevens may experience less difficulty than other Sevens with making
commitments. For instance, many Self-Preservation Sevens report that they have been married for
many years or that they have had a solid relationship with a partner for a long period of time. When
they participate in groups, however, it may be so they can feel a sense of having access to resources if
they need something at some point. Often, having close relationships is something they view as an
investment, like putting money in the bank—you always have someone you can call on if you need
some specific kind of help. For that reason they tend to be very active in the groups they join and the
networks they are affiliated with.
Naranjo explains that spiritual aspiration is not so common in Self-Preservation Sevens; they often
reject religion and tend not to believe in anything. They’re more practical, more materialistic, and
more rebellious than the other two Seven subtypes. They’re very cheerful and friendly, but also
disconnected from their emotions. They are sensuous, earthly, worldly characters who can be very
entertaining and who display a light-hearted lack of seriousness—though when it comes to finding
security through making money and establishing a network of associates, they display keen selfinterest.
When Self-Preservation Sevens have the Sexual instinct as their second most dominant instinct,
they can look more like Sixes (more isolated, overly careful, and strategic), and when they have the
Social instinct in second place, they may look more like magnanimous Eights (people-oriented and
impulsive). However, unlike Sixes, they tend to be relentlessly positive and to find security through
pursuing their self-interest; and in contrast to Eights, they tend to be motivated by a survival fear or
anxiety deeper down, even if they aren’t always aware of it.
Joe, a Self-Preservation Seven, speaks:There is a gluttonous element in me that I believe stems from an early understanding in
childhood that life is inherently evanescent. Opportunities missed are not easily regained. In
that light, as I approached my graduation from middle school and prepared to go to high
school, I realized that it was time to weigh my priorities and start planning for a career and
a life maximally lived. So, at thirteen years old, I prioritized: 1) living and enjoying life to
the fullest while it was possible; 2) helping others do the same; 3.) not hurting others along
the way. That was in eighth grade.
The road to medical school and beyond involved painful sacrifices in regards to quality of
life. I endured a decade of deferred pleasure and buried myself in my studies by making the
most of my intellectual interest in medicine and the awesome experience of becoming a
surgeon. What got me through the hard work was the clear vision I had of a complete life:
weighing the short-term missed experiences against the long-term pleasures and security
over the span of a full life as a plastic surgeon helped me see that the hardships involved in
becoming a doctor were worth it. To keep things balanced, I played hard during my brief
breaks from work and tried not to miss a minute of fun with friends on weekends or nights
While the sacrifices involved in becoming a surgeon weren’t easy, I now find myself in the
most wondrous position of having fulfilled my “mission statement”—I’ve done the most good
with the least harm while reaping additional quality-of-life benefits. I love my artist wife
beyond words. We sail and grow organic vegetables together. I enjoy the challenges of
growing grapes and making wine, and we are creating an aesthetically beautiful and selfsustaining
homestead. I relish the rewards of time at work and even more at play. What could
be better than or wrong with that?
I am aware, however, that I am less in touch with my emotions than might be ideal, as
experiencing life more intensely on many different levels makes sense to me. I enjoy the
experience when love, empathy, and other emotions well up into my consciousness, but I
usually function quite happily on a more cerebral plane. Other times, fear or anxiety may
enter the room, but I am less eager to tolerate their presence. I have learned to listen to my
intuition and emotions, but unless they present an actionable warning, I prefer not to dwell
on negative moods.
