The irreducible epistemic atoms underlying the curriculum. 4,828 atoms across 8 types and 2 molecules
Evergreen note: a self-contained, precisely named cognitive object that functions as a conceptual API, providing a complete, actionable claim that can be referenced, linked, and composed with other ideas without requiring the full content to be read
Question: a well-formed question that stays open and functions as a cognitive tool, organizing attention, generating ongoing cognitive tension, and directing future inquiry rather than simply closing a loop.
Definition: an operational definition that specifies the precise, observable conditions under which a term applies, functioning as a load-bearing structural element in reasoning that shapes every conclusion built on top of it.
Duplication: the epistemic signal that identical or highly similar structural patterns have been recorded in multiple locations without linking to a shared abstraction, indicating that a pattern has been recognized but not yet named
Abstraction: the cognitive process of extracting and naming a shared structural pattern from multiple concrete instances, creating a concept that can be referenced, refined, and composed with other concepts, enabling knowledge to compound in value
Atomicity: the practice of decomposing ideas into discrete, independent units that can be independently understood, linked, and reused, where the goal is incremental improvement rather than perfect adherence to a fixed rule
Ubiquitous capture tools: capture tools that are available in every context where thinking occurs — desk, commute, shower, conversation, bed — such that no gap exists between where thoughts arise and where they can be externalized within seconds
Single thought inbox: a single, append-only destination where every captured thought enters and which is processed regularly to zero, functioning as a waystation rather than storage where all unprocessed thoughts accumulate until decision-making occurs
Open loop: an active mental representation of an incomplete task or commitment that continuously consumes working memory and creates cognitive tension until externalized into a trusted system
Processing: the cognitive operation of deciding what to do with each item — specifically answering 'What is this? Is it actionable? What is the very next physical action?' — before organizing that item into a knowledge management system
Batch processing: the cognitive infrastructure defense strategy that accumulates interruptive items and processes them in dedicated time windows rather than handling each item as it arrives, thereby protecting cognitive depth and preventing attention residue
Attention residue: the structural property of human cognition where cognitive threads from an unfinished task compete for attention bandwidth during subsequent tasks, creating a hard floor on task-switching costs that preparation cannot eliminate
Context-dependent memory: the structural constraint on human memory where retrieval cues are effective only if they were encoded alongside the original memory, with conditions of recall needing to overlap with conditions of learning for successful retrieval
Voice capture: the practice of using spoken language as a primary cognitive capture method, particularly in high-friction moments when text input is impossible or impractical, to preserve insights that would otherwise be lost due to the temporal and physical constraints of human cognition
Photograph as capture: the practice of using visual documentation as a primary cognitive capture method for spatial, visual, or environmental information that cannot be adequately represented through sequential text, leveraging the brain's dual coding pathways to preserve information with superior retention compared to verbal description alone
Capture trigger: a behavioral anchor that automatically initiates a capture action by linking a pre-existing habit to a specific capture behavior through a 'after I [existing habit], I will [capture behavior]' formula
Automaticity: the state where a behavior becomes reliably performed without conscious effort or willpower, typically achieved through repeated pairing of a cue with a response over 18-254 days
Hot capture: the cognitive process of rapidly recording fleeting thoughts, ideas, or observations without immediate organization or refinement, occurring in a temporary, frictionless storage system designed for speed of entry rather than quality of output
Capture resistance: the psychological mechanism where individuals consciously or unconsciously avoid externalizing certain thoughts due to the emotional discomfort, cognitive dissonance, or experiential avoidance that concrete expression would trigger, serving as a diagnostic signal about what matters most to the individual
Conversational memory: the cognitive process by which information exchanged during social interactions is encoded, stored, and retrieved, characterized by systematic forgetting patterns, gist-based recall, and source monitoring failures that make it particularly unreliable for decision-making
Third brain: the externalized cognitive infrastructure that extends human mental capabilities through tools, systems, and artifacts that enable information processing, storage, retrieval, and integration beyond the biological limitations of individual cognition
Emotion: a somatic marker that represents a brain's prediction about what bodily sensations mean in the current context, based on prior experience and learned categories, serving as essential data for decision-making rather than noise interfering with rational thought
Surprise: the neurochemical signal generated by prediction error when reality differs from expectation, serving as the primary learning trigger in biological systems and indicating a gap between one's internal model and external reality
Decision journal: a structured record of decisions that captures not just what was decided but why, including the reasoning, expected outcomes, and review dates, designed to preserve the actual decision-making process before hindsight bias can contaminate memory
