The irreducible epistemic atoms underlying the curriculum. 4,828 atoms across 8 types and 2 molecules
Thoughts are objects, not identity: discrete cognitive entities that can be separated from the identity of the thinker; a person can observe, craft, version, and evaluate their own thoughts as external material
Uncaptured thoughts: novel cognitive signals that arrive as fleeting signals and systematically degrade in memory within seconds without a capture practice, with 42% degradation occurring within 20 minutes according to Ebbinghaus's forgetting curve
Externalization: the act of transforming internal emotional states from vague, unmanageable experiences into precise, labeled, written objects that can be examined, tracked, and acted upon deliberately
WYSIATI: the cognitive bias where people treat available information as complete and determine confidence based on the coherence of the available story rather than the quantity or quality of supporting evidence, with the system that would detect gaps being the same system that has the gaps
Capture: the cognitive process of externalizing thoughts and ideas from working memory into an external medium for preservation and future processing
Monitoring: the upward communication channel in metacognition where cognition about cognition is perceived, representing the signal that tells you 'I don't actually understand this' or 'I'm getting emotional about this decision'
Control: the downward communication channel in metacognition where actions are taken in response to monitoring signals, such as 'I need to re-read this more carefully' or 'Let me step back and separate my feelings from the facts'
Cognitive offloading: the use of physical action to alter the information processing requirements of a task so as to reduce cognitive demand
Shelf life of a thought: the rate at which a thought decays and becomes unrecoverable, which varies from minutes for contextual insights to weeks or permanent for reference facts
Zeigarnik residue: the persistent sense that you had something important (a task-specific tension) without the actual content of the insight, which continues consuming working memory without delivering usable information
Capture habit: the reflexive, automatic behavior that externalizes ideas the moment they arrive, consisting of a cue (trigger), routine (behavior), and reward (reinforcement) that forms a neural pathway requiring no willpower or decision-making
Keystone habit: a foundational behavior that, once established, cascades into other behavioral changes across seemingly unrelated areas by restructuring the conditions that make other outcomes possible, rather than just producing its own outcome
Internal monologue: the compressed, lossy cognitive process that represents thoughts through abbreviated, predicative, semantically condensed fragments rather than faithful recordings, systematically omitting subjects, context, nuance, counterarguments, emotional metadata, and uncertainty markers while running known distortion patterns that make it unreliable as a high-fidelity representation of actual thinking
Observation: the cognitive act of attending to and monitoring one's own thinking that necessarily alters the content and emotional charge of the thought being observed through the engagement of prefrontal regulatory circuits that modulate limbic activation, making the observer and observed part of the same system rather than separate entities
Confusion: the gap between what you think you understand and what you can write down clearly, which reveals the exact contours of your misunderstanding and serves as diagnostic information
The illusion of explanatory depth: the phenomenon where people rate their understanding of everyday devices highly but experience a significant drop in self-assessment when forced to articulate detailed explanations, revealing shallow knowledge that was masked by the feeling of understanding
Review: the cognitive operation that transforms captured material into usable knowledge through evaluation, connection, and decision-making processes
Capture system: the integrated infrastructure of multiple capture channels and a single consolidation point that prevents loss of cognitive raw material
Atomic note: a note that captures exactly one idea, is self-contained enough to be understood without its original context, makes one assertion, develops one concept, or captures one argument, and can be linked to, referenced from, and embedded in any context where its single idea is relevant
Unique identifier: a stable, distinct address assigned to an idea or information resource that enables precise referencing, linking, and retrieval without ambiguity, regardless of changes to the idea's title or content
Decomposition: the cognitive process of breaking down complex ideas, systems, or concepts into smaller, more manageable components to reveal hidden complexity, dependencies, and gaps in understanding, thereby making the actual complexity visible and actionable
Illusion of explanatory depth: the cognitive bias where people overestimate their understanding of familiar concepts or systems, believing they can explain them fully until they attempt to break them down into component parts, at which point the gaps in their knowledge become apparent
Atomicity: the property of cognitive objects that makes them self-contained, independently understandable, and capable of being recombined with other atomic objects to generate novel insights or structures that monoliths cannot produce
Precise naming: the cognitive act of creating self-contained, declarative labels for ideas that convert fuzzy intuitions into findable, retrievable, composable objects and fundamentally change what can be thought about by establishing clear conceptual boundaries
