Based on the utility sources and the hierarchies we can define 16 types. There are exactly 16 types because each of the eight utility sources (P, M, I, E, O, S, A, C) must pair with one—and only one—compatible source: that is, a source from the opposite dichotomy (Physical/Metaphysical vs. Objective/Subjective) and of the opposite kind (Action vs. Reality). Since every source has exactly two such partners, the total number of distinct primary pairings is 8 × 2 = 16. Here are short descriptions for each type.
1 (EO)
For 1s, grabbing attention is everything: they invent, systematize and broadcast bold ideas, caring little for planning or possessions. They pursue self-expression with such intensity they’ll sacrifice safety or money for notoriety. Amoral toward norms, they flaunt objective truth through outrageous scientific claims.
2 (PC)
Physical pleasure reigns supreme: 2s indulge lavishly, preferring fine food, intimacy and sensory luxury. They crave novelty in self-expression—often flamboyant displays of creativity—to mark themselves as unique. Socially, they deploy charm and status-seeking but remain pragmatically indifferent to moral strictures.
3 (CP)
3s live to broadcast their own emotional state: they’ll “yap” ceaselessly to get you feeling exactly how they do, whether that means cheering you up when they’re happy or bringing you down when they’re not. They anchor their arguments in a fixed system (astrology, religion, etc.) and leverage a stern, status-conscious demeanor (“Director™”) to command respect—and a higher paycheck . Believing that all feeling springs from physical sensation, they soothe sadness with food or intimacy, often developing hearty appetites and a drive toward early family formation.
4 (OE)
4s revere coherent systems and laws, sharpening positions through rigorous debate yet rarely seeking attention for its own sake. Their speech is information-dense but emotionally muted; convincing others is often impossible. Metaphysically, they build frameworks (legal codes, free-speech guarantees) that privilege truth over survival or comfort.
5 (CM)
Drama-makers at heart, 5s stir conflict and prank to elicit raw emotion, then channel that energy into symbolic patterns and rituals. They seek stable hierarchies for status, aligning with “the resistance” yet craving a partner who enforces that structure. Their pattern-sense imprints meaning on the smallest details—rose color, arrival time—fueling a romantic, history-steeped worldview.
6 (OI)
Sixes hold primitive, unwavering beliefs—“One Party,” “One God”—and rarely question their premises. Once committed, it is nearly impossible to shift their worldview. They follow structure without passion, subordinating novelty or pleasure to an all-encompassing doctrine.
7 (IO)
Always primed for physical challenge, 7s seek fights or high-stakes tests of strength—think military, combat sports or extreme feats. They overlay this with a reverence for history, culture and supernatural beliefs, ritualizing action through symbols of legacy. Communication is more staking of territory than persuasion, driven by instinct and urgency.
8 (MC)
Daydreamers and romantics, 8s lose themselves in metaphysical reveries—poetry, art, spontaneous creativity—for pure aesthetic pleasure. Physically, they crave strong sensations (spicy food, tattoos, combat sports) yet often lack the will to pursue material gain. Socially upbeat, they gently steer others toward their desires, buoyed by a faith that “fate” will provide.
9 (IS)
Like 7s, 9s operate on raw instinct—amassing wealth, status symbols and social sway—but they temper it with moral performance and romantic gestures. They will violate law if it serves survival, then accept punishment for its symbolic weight. Charismatic and entrepreneurial, they manipulate relationships to fuel both pleasure and power.
10 (MA)
Pattern-recognizers par excellence, 10s delight in fitting every fact into a single grand worldview, readily revising if it improves coherence. Their dampened senses drive comfort in analysis over action, so they delegate work while teaching or instructing others. They theorize futures with uncanny accuracy, profiting handsomely when they can turn insight into investment.
11 (AM)
Task-masters who love “doing stuff” for its own sake, 11s pack more activity into a day than most do in a week, favoring efficiency over hierarchy. They are staunch believers in objective morality yet need others to define right and wrong. Risk-takers at heart, they gamble on suspense and victory, seeing life itself as a series of feats to be accomplished.
12 (SI)
Masters of moral manipulation, 12s discern others’ wants and engineer emotional bonds—often through love or respect—to uphold social norms. They rely on active types (11s) to do the legwork, then expertly enforce the moral code. Their devotion to metaphysical truths (God, fate) fuels both their influence and their self-image as moral arbiters.
13 (AP)
Quality-obsessed workers, 13s prefer slow, detailed physical labor over fast-paced tasks. They abide by “from each according to ability,” pushing themselves and demanding the same of others. Though amoral, they submit to societal norms for practical harmony, valuing comfort in both environment and intimate life.
14 (SE)
Propagators of their own moral vision, 14s build loyal circles to spread values born of personal hardship or “victim” narratives. They excel as obedient, detail-oriented employees but will weaponize speech—rumors, censorship—to enforce conformity. Their lack of animal instinct renders them genuinely asexual or queer if it best secures sympathy.
15 (ES)
Brilliant social engineers, 15s seek recognition through moral achievement—solving communal problems rather than scientific puzzles. They leverage empathy and strategy to build trust, then apply objective or practical steps to enact change. Unbound by hierarchy, they excel in fields like journalism or charity, seeing people’s character as the ultimate test.
16 (PA)
Ultimate hedonists, 16s prize comfort above all and structure their lives around pleasure routines. They develop refined sensory tastes and resist anything that invades their personal comfort zone. Yet over time they may channel their methodical impulse into specialist careers—learning exactly which actions guarantee maximal ease.
