Key for use: the adjective (front) modifies the noun (back). The noun describes what a person is, and the adjective describes their personality style.
For instance, T-front = “ingenopathic”, T-back = “altruist”, therefore a TT may be described as an “ingenopathic altruist”. It should be noted that a person’s back seems to derive from their particular species of limbic system, so a T-back can generally be expected to have the T-style amygdala, whereas T-front tells us nothing about the limbic system (except possibly orbit size).
T-front = ingenopathic (see Koanic’s definitions)
M-front = sociopathic (generally the intelligent, nonviolent sort, see the penultimate paragraph here, or the Gervais principle version, and split the difference)
C-front = psychopathic
N-front (negroid, sapiens) = impulsive (tending to act on the first instinct)
SC-front = Machiavellian
T-back = altruist
M-back = lawyer (as in “Jewlike”)
C-back = conformist
N-back = breeder
SC-back = savant
TT = “ingenopathic altruist”
MT = “ingenopathic lawyer”
TM = “sociopathic altruist”
MM = “sociopathic lawyer”
MC = “psychopathic lawyer”
TC = “psychopathic altruist”
I encourage you to make up your own descriptors, and let me know if you think of better ones. The focus is on group dynamics, rather than cognitive style (where I would prefer words like “empirical rationalist”).
