The following is an incomplete draft description of the ESFp exertion type. Although the ego section is finished (first paragraph), the superego section is still in progress.

In the world of ESFp, there are many forces in existence, each with the ability
to stoke definite kinds of emotion. The stronger forces prove the determinants
of what emotions are felt: set an inertia to an object, and it will continue
on of its own will, disrupting the path of whatever is in its way. Therefore
when a force is set in motion, there will always be feelings that emerge in
reaction to its effects. The ESFp type is adept at using force to create an
emotive "balance", a set of competing wills that are evenly matched, so as
to effect a stable situation. Specifically, the ESFp desires the advent of
peace, and gives volition to the forces that can create it.

The problem with peace is that it is often uneven. There must always be someone
watching over it, or it will not last. This someone has the capacity, in their
position of overlordship, to restructure reality in the context of the existing
stasis. Although this someone is invariably another person, their influence will
always manifest as a social dynamic of peace: peace, once attained, must be
preserved. However, stability does not imply a lack of change; it only means that
what changes are made do not threaten the general emotional state of the peace.
It falls to the ESFp to provide rules for the specific peace obtained, and a
means of their administration. The key to a successful rule lies in the
regulation of possible expressions of a given emotive state. In the context of
peace, there are many possibilities available that do not threaten the peace
itself, but may threaten society. Dictatorships, for example, are technically
"at peace" internally, but the expressions of that peace are invariably fear.
I suspect that what is herein described may ring a bell with one or more members of this forum. Please critique at your leisure. In particular, I need assistance in understanding how the ESFp exertion type produces the structure/regulation ( energy) society requires of them. (vulnerable energy function)

I suspect that Thomas Jefferson is an example of an ESFp exertion type, particularly due to this passage from the Declaration of Independence:
That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
From my vantagepoint, this passage seems particularly concerned with the exertion ESFp experience of superego. Jefferson's INTj metabolism type is also relevant: government must be instituted in a state (an act of energy within an context of "internal peace") to defend the individual's vulnerabilities. ( for INTj) The powers of the government are described as "just", which is a concept. The power of the government is carefully organized (), however, so as to allow for the experiences of safety and happiness. ()
