So, I went through Ocean Moonshine's general 5 description and copied the sections I strongly identified with. I'd say the bolded sections are key aspects of my personality. I'm thinking it's pretty likely I'm a 5 ?
"Some Fives prefer to keep their theorizing to their private lives, while making a living doing something that requires little intellectual energy. Such Fives can be recognized by their need for privacy, their focus on competency, and their attitude of restrained indifference to authorities and to the rules and procedures of the workplace."
"Others in the Five’s life often recognize, if only on an intuitive level, that some part of the Five is not quite present. It is that part which Fives reserve for themselves and perhaps share with a very few others. For most Fives, a great deal is kept in reserve."
"Fives are frequently uncomfortable in the social realm. Part of this stems from the Five’s eccentricity, which in turn stems from the fact that Fives spend so much time in the realm of thought."
"tend to have permeable ego boundaries and often sense the unspoken thoughts and unexpressed feelings of those in their environments. These tend to feel invasive to Fives, who characteristically withdraw in order to protect their boundaries."
"Perhaps Rilke, a Five himself, more than anyone else, expressed the ideal form of relationship for a type Five individual: ‘Once the realization is accepted that even between the closest human beings infinite distances continue, a wonderful living side by side can grow, if they succeed in loving the distance between them which makes it possible for each to see the other whole against the sky.’"
"often find themselves processing their emotions later, in the privacy of their rooms"
"As Fives fear being intruded upon themselves, they likewise fear intruding on others. And, finally, as Fives can generally sense what is going on beneath the surface with others, they tend to expect the same in return. Words and overt expressions of emotion almost feel ‘too much.’”
"Fives don’t tend to think of themselves as being unemotional and are often surprised when they realize just what a disjunct there is between their own perception of themselves and the perceptions that others have of them. This frequently exacerbates the Five’s feelings of alienation and adds to their sense that human relationships are somehow essentially flawed. (Jean-Paul Sartre, for instance, a classic type Five, considered human relationships to be that from which one could neither escape nor find true satisfaction; there was thus “no exit.”)"
"Fives tend to withhold themselves from others, from emotional involvement and sometimes from life itself. There are many Fives who have accumulated a vast wealth of knowledge, which they never share with anyone; in this way, their characteristic ‘gold’ never benefits the world from which Fives typically feel so alienated. And there are many more Fives who only share their knowledge, who never truly share the depth or uniqueness of their being even in the context of their closest personal relationships. Their fear gets in the way."
