Relationships
the connections between entities that carry meaning equal to or greater than the entities themselves, with the structural properties of the connections determining what is possible and what isn't
Knowledge graph
a structured network of interconnected concepts where nodes represent ideas and edges represent relationships between them, with gaps indicating knowledge deficiencies and structural holes revealing blocked channels for insight
Explicit relationship
a connection between two precisely named entities that is stated with a specific relationship type (causal, correlational, temporal, enabling, inhibiting, or other) and supported by a documented evidence basis, making the relationship inspectable, testable, and subject to correction
Illusory correlation
the tendency to perceive a relationship between two things based on expectation rather than evidence, particularly when semantically associated pairs are overestimated as co-occurring even when actual data shows no correlation
Apophenia
the tendency to perceive meaningful connections between unrelated things, particularly in the absence of actual relationships, which evolved as a pattern-detection mechanism that prioritizes false positives over false negatives
Causal relationship
a relationship between two things where a change in one thing produces a change in another through some mechanism, distinguished by interventionability - if you change the cause, the effect changes
Directed relationship
a connection between A and B where the relationship has an arrow flowing from a source to a target, from an origin to a destination, and the relationship means differently in each direction, with (A, B) being distinct from (B, A) in mathematical notation
Feedback loop
a structure formed when directed relationships create cycles where A affects B and B affects A, producing emergent properties that cannot be understood by examining any single arrow in isolation, with the cycle itself having properties distinct from individual directed arrows
Prerequisite relationship
a directed relationship between concepts where the dependent concept cannot be achieved without the prerequisite concept, characterized by necessity, asymmetry, and transitivity, and forming a directed acyclic graph structure
Contradictory relationship
a connection between two ideas in a knowledge system where both ideas have genuine evidence behind them, where both have served the individual well, and where the individual cannot hold both as fully true in the same sense at the same time
Surface contradiction
an apparent conflict between two beliefs that dissolves once you clarify the terms, scope, or context, resolving through clarification without cascading changes to other beliefs in the system
Structural contradiction
a contradictory relationship built into the structure of a domain, arising from competing demands within a system, that cannot be permanently resolved but only dynamically managed
Generative contradiction
a type of contradictory relationship where holding both sides simultaneously produces something that neither side could produce alone, serving as an engine for conceptual development and creative breakthroughs
Triangulation
the methodological approach of using multiple independent sources, observers, theories, or methods to validate a hypothesis or schema, where the independence of evidence sources creates meaningful convergence
Causal chain
a sequence of cause-and-effect relationships where each effect becomes the cause of the next link, with each link being a relationship that can be individually verified and tested, and where removing any single link breaks the chain and prevents the final outcome
Balancing loop
a feedback loop that resists change by pushing a system back toward a target, set point, or equilibrium, counteracting deviations from that target
System structure
the pattern that emerges when you see all the relationships between components simultaneously, which determines system behavior rather than individual components or actors
Implicit schema
a schema that operates below conscious awareness, activates automatically without deliberate control, and influences judgment and behavior without the person knowing it happened
Event schema (script)
a structured knowledge representation for familiar event sequences that determines what is noticed in an event, how it is interpreted, and what responses are considered appropriate or automatic
Transitive relationship
a relationship type where if entity A relates to entity B and entity B relates to entity C, then entity A also relates to entity C, with the relationship type being consistent across all links in the chain
Transitive inference
the automatic cognitive operation of computing implied relationships from chains of explicit relationships without conscious effort, where the relationship type must support transitivity for the inference to be valid
Redundancy
the presence of multiple independent paths between critical nodes in a system, where each path does not share a failure mode with the others, such that the system remains connected and functional even when some paths fail.
Bottleneck
a structural feature of a system — a node or connection through which disproportionate flow must pass, creating a constraint that governs the throughput of the entire system
Articulation point
a node whose removal disconnects the graph — meaning parts of the network that were previously connected can no longer reach each other
Epistemic action
a type of action that changes the world in order to simplify a cognitive task, thereby enabling more efficient thinking rather than simply moving physically closer to a goal
Cognitive artifact
a tool or representation that reorganizes cognitive processes and actively participates in thinking rather than passively storing information
Nesting
the universal property of meaning organization where any concept contains sub-concepts and belongs to super-concepts, forming a recursive hierarchical structure that repeats at every scale and enables complex systems to organize themselves through stable intermediate forms
Recursive structure
a nested system defined in terms of itself where a single rule generates infinite depth, enabling the same structural pattern to operate at every level of organization without requiring different rules for each scale
Lattice
a directed acyclic graph where every node can have multiple parents and every pair of elements has both a unique least upper bound (join) and a unique greatest lower bound (meet), representing the multidimensional nature of knowledge where concepts genuinely belong to multiple categories simultaneously
Polyhierarchy
a design principle in knowledge organization where concepts genuinely belong to multiple parent categories simultaneously, as opposed to tree structures that force concepts into single parent relationships, preserving retrieval paths from multiple access dimensions
Override
an explicit, deliberate annotation or modification that modifies or replaces a specific inherited property from a parent node, indicating that while the child item inherits from the parent, it does not conform to that specific inherited characteristic due to its unique context or requirements.
Progressive disclosure
the information architecture principle that structures content in layers where each level provides sufficient context to decide whether to drill deeper, ensuring that overview is presented first and detail is available on demand rather than forcing users to consume everything at once
Containment
the structural relationship where an item exists as part of a parent entity, shares the parent's lifecycle, and cannot be accessed independently.
Hierarchical thinking
the fundamental cognitive capability to organize things into nested levels and move between those levels with purpose, operating as a core architectural feature of human cognition and manifesting in neural hierarchy, linguistic structure, developmental milestones, and system design principles
Personal experiment
a specific, actionable test designed to validate or invalidate a schema through controlled observation and measurement
Schema test
a structured action designed to evaluate a schema by making a falsifiable prediction, taking defined action, observing results, and specifying revision triggers, where the test must have genuine risk of falsification to be valid
Indirectly validatable schema
a schema that cannot be confirmed or disconfirmed through a single direct observation but can be validated through convergence of multiple independent indicators from different domains
Epistemic confidence
the level of confidence that tracks the evidential basis for a belief, as opposed to psychological confidence which tracks how central the belief feels to one's identity and worldview
Schema validation
the systematic practice of testing beliefs against evidence, welcoming disconfirmation, and refusing to protect comfortable models from uncomfortable data
Emotional tolerance for schema change
the capacity to endure the physiological discomfort and emotional resistance that arises when confronting contradictory evidence about deeply held beliefs, without immediately resolving it through dismissal or rationalization
Incremental schema revision
the practice of making small, frequent adjustments to mental models rather than large, rare overhauls, which preserves functional structure while correcting dysfunctional elements and operates within working memory constraints
Schema debt
the compounding liability that accumulates when a mental model is known to be inaccurate but is not updated, with interest payments manifesting as suboptimal decisions, wasted effort, and degraded performance in the domain the schema describes
Trigger conditions
specific, observable signals or thresholds that automatically prompt schema review regardless of subjective judgment, defined prospectively before problems are suspected and designed to detect schema degradation early
Anomaly
a specific instance where reality contradicts an expectation generated by a mental schema, which becomes significant when it clusters with other similar instances, signaling that the underlying schema requires revision
Shared schema
an emergent cognitive structure that exists across people, embedded in their habits, language, tools, and coordination patterns, and which changes more slowly than individual schemas due to the need for synchronized updates across all members who rely on it
Schema rigidity
the systematic bias produced by maintaining outdated mental models that do not update in response to environmental change, resulting in increasingly suboptimal decisions that compound over time
Zero-base test
a diagnostic tool for detecting schema rigidity that determines whether you would adopt the same belief as a newcomer encountering the situation fresh, with no prior commitment
Schema evolution log
a written record that traces the exact moment when a major belief or model changed, the specific evidence that initiated the revision, the prior belief as it was originally held, and the new belief, maintained in real time before hindsight rewrites the narrative
