A field of scattered observations, one trajectory fitted through them — and a single construct riding the line through time, already sure of where it bends.
Zone B · stack position
Click any position to see how the read changes — from the unhurried, inexorable funnel of a dominant to the demon's single black certainty that fires on almost nothing. Watch the convergence readout: it tells the whole story before the caption does. Drag the maturity slider to watch the lower positions slowly gain fidelity with age.

With age, lower stack positions gain fidelity, duty cycle, and structural complexity.
Zone C · feeder coupling
Introverted judging is fed by extraverted perception — and extraverted judging by introverted perception. Ni is introverted perception, so its real partners are the extraverted judgers: Te and Fe. Click a feeder to watch what converges.

Zone D · the regression engine
Ni fits one predictive trajectory through noisy, many-dimensional input, then rides it forward in time. This lab exposes the engine's live state — stress, pleasure, confidence, loss — and five ways a day can treat it. Trigger a scenario and watch the telemetry answer; hover the chamber at any time to steer the construct through time yourself.
Zone E · energy economics
Every invocation of Ni costs energy. The lower it sits in the stack, the more expensive it becomes. Note the small notches in the dominant curve: an insight that lands pays a little back. Note also which way the grip runs here — a collapsed Ni-dominant does not get more Ni, it floods into inferior Se.
Zone F · field notes
Patterns from the wild — how Ni shows up in daily life.
Ten minutes in, an Ni-dominant knows how the project ends, and says so. Asked why, they produce a reason that is true but is not the reason — it is the nearest sayable thing to a read that never had steps. Six months later they turn out to be right, which does nothing at all to improve the next explanation.
Under stress, INFJ Ni pairs with tertiary Ti: both introverted, both inward, with Fe's contact with actual people cut out between them. The read gets more elaborate, more internally consistent, and more certain, and nobody outside that head has touched it in weeks.
An INTJ past the end of their reserves stops seeing where anything is going and floods into inferior Se — buying things, driving too fast, eating and drinking past the point of noticing, working the body until it is the only thing in the room. Not a personality change: a low-capacity chamber taking a dominant-sized flood.
Same element, opposite attitude — and the difference is which way the funnel points. Ne takes one input and fans it into many futures, all live at once, all cheap to hold, none of them chosen. Ni takes many inputs and funnels them into one, and that one arrives whole, expensive to change, and impossible to show. Ne trades commitment for range; Ni trades range for a conviction it cannot source.
