Mental Model

Tragedy of the Commons

A tragedy of the commons can occur when individual users receive benefits from a subtractable shared resource while depletion costs are spread among others

Cognitive Move

Traits to states

Stop describing something as a permanent property of a person or thing, and describe it instead as a condition that switches on and off. The question becomes what turns it on, how long it lasts, and what turns it off.

Cognitive Move

Trajectory and scenario

Continues the line you are on past today as a widening band or a set of named futures, so direction and uncertainty show together.

Cognitive Move

Trajectory or rate

A desired direction and pace of change across time, where the slope matters more than any snapshot.

Mental Model

Transfer of Learning (Near vs Far)

The influence of learning on performance in another task or context, with similarity and difference varying across several dimensions.

Cognitive Move

Transfer only preserved structure

After the mismatch audit, carry across only the role-to-role relations that survived it, and leave the rest behind. Everything the audit flagged as broken stops being available for reasoning, no matter how vivid or convenient the imagery still feels.

Cognitive Move

Transfer trouble

Your evidence came from a different person, context, scale, or incentive regime and is being stretched past its borders.

Mental Model

Transference and Countertransference

Transference occurs when a client unconsciously redirects feelings, expectations, and relational patterns from past significant relationships (especially early caregivers) onto the therapist

Cognitive Move

transition matrix

The same information as a grid instead of a picture. Where you were down the side, where you went across the top, and a count in every cell for how many times that move actually happened. The zeros are the point. An empty cell is a move you have never made, and a row that empties into a single column is a habit you did not know you had. It also scales past the point where arrows turn into a tangle.

Cognitive Move

Translator

Ask whether the entity mainly converts one form of information into another so two sides can work together: vague into specific, technical into plain, one team's vocabulary into another's. Nothing new is produced; meaning is carried across a gap.

Mental Model

Trapped in the Robot Control Room

This thought experiment asks how signals inside a robot could become meaningful when their interpreter has no independent view of the surrounding world

Mental Model

Trauma-Informed Care Framework

Trauma-informed care (TIC) is not a specific treatment technique but an organizational and relational framework that shifts the guiding question from 'What's wrong with you?' to 'What happened to you?' SAMHSA defines its…

Cognitive Move

tree

The plain nesting: a root at the top, children below it, one line into each box. Depth means level, and the leaves are what you can act on. The useful discipline is stopping. Open a branch only until its leaves are things you could do tomorrow, and leave the branches you are not working on closed.

Cognitive Move

treemap

Nested rectangles where area is a real quantity. Containment and magnitude land in the same picture, so a category that looks like one item in a list can look like half the page here. It needs a quantity you can defend. Without one, the eye reads size as importance and invents a finding.

Cognitive Move

TRIAGE (RUN / BUFFER / STOP-ESCALATE)

Before adjusting anything, sort the moment into 3 outcomes: proceed because access is fine, support first because 1 function is fragile, or stop and get safety or care because self-help isn't the right tool.

Mental Model

Triage System Framework

Triage is the systematic process of prioritizing patients based on the severity of their condition and the resources available — not based on who arrived first or who is most vocal

Cognitive Move

Triangulate

The middle verdict: the number survives, but never travels alone. You pair it with two or three companion signals chosen to catch exactly the distortions the prosecution named, and you refuse to read any of them in isolation again.

Mental Model

Triangulation in Relationships

The failure pattern where two-person conflicts are managed by involving a third party, which reduces immediate tension but prevents resolution and corrupts three relationships simultaneously

Mental Model

Tribalism

The deep human tendency to divide the world into in-groups and out-groups, then favor the in-group and demonize the out-group—often based on minimal or arbitrary distinctions

Mental Model

Trickster Archetype as Teaching Model

The Trickster is a cross-cultural archetype -- Anansi (Akan/West African), Eshu/Elegba (Yoruba), Coyote (Plains Nations), Raven (Pacific Northwest), Maui (Polynesian) -- who teaches through boundary violation, paradox, a…
