Cognitive Move

Causal effect

Find out whether changing this factor actually changes the outcome, not just whether they appear together.

Cognitive Move

causal loop

Named factors joined by signed arrows into a closed circuit. An arrow carries a plus when more of one means more of the other, and a minus when more means less. Count the minus signs: an even number makes the circuit reinforcing, marked R, and it amplifies whatever it starts with. An odd number makes it balancing, marked B, and it pulls back toward a target. Hash marks across an arrow say the effect lands later.

Causal Loop Diagram

A visual mapping tool from systems dynamics that traces how variables influence each other in feedback loops

Mental Model

Causation vs. Correlation

The fundamental distinction between two variables that MOVE TOGETHER (correlation) and one variable actually PRODUCING change in another (causation)

Cognitive Move

Ceiling

Name the point where more stops helping and starts hurting, then forbid crossing it. Unlike a floor (a minimum you protect) or a budget (a total you spend down), this caps intensity, dose, risk, or exposure. Watch that the cap does not become a target people drive up to.

Cognitive Move

Ceiling

A maximum you should not exceed because more becomes toxic, fragile, or not worth its cost.

Cognitive Move

Ceiling Ahead

A hypothesis that growth is activating a limiting constraint that will plateau or reverse it.

Cognitive Move

Ceiling Hunt

Ask which resource, capacity, trust, or permission will cap the next gain before you chase it.

Mental Model

Centering Prayer, developed by Thomas Keating, William Meninger, and Basil Pennington in the 1970s, is a Christian contemplative practice that closely parallels Eastern meditation but is rooted in the Christian apophatic…

Mental Model

Central Limit Theorem

The central limit theorem gives conditions under which centered and scaled sums or means approach a normal distribution as sample size grows.

Mental Model

Ceremony as Knowledge Practice

In many Indigenous epistemologies, ceremony is not ritual or performance but a rigorous knowledge practice -- a structured methodology for accessing, validating, transmitting, and renewing knowledge

Mental Model

Chain of Custody Logic

Chain of custody is the documented trail showing who possessed a piece of evidence, when, and what they did with it — from collection to courtroom presentation

Mental Model

Change the Field

If your thinking tracks the noise, light, interruptions, or pressure around you, change the environment once instead of demanding more self-control.
