Expertise
the ability to efficiently process information by automatically filtering out irrelevant data and focusing on signal, achieved through structured pattern exposure that changes perceptual processing itself rather than simply accumulating more information
Chunking
the cognitive process of compressing multiple discrete pieces of information into larger meaningful units that consume one working memory slot while carrying the information density of multiple items, enabling experts to process more meaning with the same working memory capacity
Premature closure
the cognitive bias that leads individuals to accept an initial interpretation or diagnosis as final before it has been fully verified, characterized by anchoring on first data, confirmation bias, and search satisficing.
Naive realism
the pervasive cognitive distortion characterized by three interlocking assumptions - that one perceives events as they actually are (transparent window belief), that rational people given same information will reach same conclusions (shared reality expectation), and that disagreement indicates others are uninformed, irrational, or biased (external attribution bias) - which protects all other biases from examination by making the belief in objective perception feel like common sense
Calibration
the alignment between your confidence and your accuracy, measured by the correspondence between stated confidence levels and actual outcome frequencies across multiple predictions
Well-calibrated perception
the cognitive infrastructure that aligns subjective confidence with objective accuracy through structured feedback loops, physiological monitoring, bias recognition, and domain-specific calibration practices
Overconfidence
the systematic, predictable, measurable error where humans exhibit excessive confidence in their knowledge, estimates, and performance, characterized by three distinct forms—overestimation of actual performance, overplacement relative to others, and overprecision of confidence intervals—that behave differently across task difficulty levels and operate below the surface of conscious awareness
Overprecision
the form of overconfidence where individuals believe their estimates are more accurate than they actually are, demonstrated by confidence intervals that are too narrow and fail to capture true values at the stated confidence level
Prediction tracking
the practice of recording specific probabilistic predictions with confidence levels, reasoning, and resolution dates, then scoring outcomes against stated probabilities to make miscalibrations visible and enable calibration feedback
Somatic marker hypothesis
emotions are not just distorters of good decision-making — they are necessary components of it - the theory that emotions provide necessary pre-conscious signals that bias attention toward or away from certain options before deliberate analysis begins
Sleep deprivation
the condition where insufficient sleep impairs cognitive performance to the degree that it equals or exceeds the impairment caused by moderate alcohol intoxication, while simultaneously degrading the brain systems responsible for self-monitoring and error detection
Perceptual calibration
the process of empirically measuring and adjusting for physiological states that systematically distort perception, specifically including sleep deprivation as a measurable input that affects the accuracy of one's cognitive instrument
Stress-induced perceptual narrowing
the neurobiological phenomenon where emotional arousal physically contracts the perceptual field by reducing prefrontal cortex engagement and increasing amygdala dominance, resulting in measurable loss of contextual information processing and cognitive flexibility under stress
Metabolic state
the physiological condition of the body, particularly blood glucose levels, that measurably alters cognitive performance, perception, and judgment by affecting attention, working memory, processing speed, executive function, and emotional regulation
Hungry judgment
the phenomenon where metabolic depletion, particularly low blood glucose, creates a negative affective filter that distorts perception and judgment by making negative interpretations more accessible and positive interpretations less so, without the individual recognizing the metabolic influence
Domain-specific calibration
the epistemic skill where confidence accurately reflects accuracy within a particular domain, requiring repeated feedback cycles and specific learning experiences that cannot be transferred to other domains
Calibration instrument
a person or system that provides external data about systematic errors in one's perception or behavior that cannot be detected through introspection alone
Blind spot
the quadrant in the Johari Window that contains what others can see about you but you cannot see about yourself, representing systematic errors in self-perception that are detectable through peer feedback
Peer feedback
structured, solicited observations from multiple independent people about one's behavior, beliefs, or perceptions that serve as calibration data to correct systematic blind spots
Calibration profile
a document that maps specific domains, confidence levels, and conditions where an individual's perceptual judgments are systematically accurate or distorted, serving as a correction map for future confidence adjustments
Natural frequency
a representation format for statistical information that expresses probabilities as counts or frequencies of events within a population rather than as abstract percentages or decimals
Personal bias profile
a specific, empirically grounded map of which biases operate most strongly in your cognition, in which domains, and with what magnitude
Systematic bias
predictable directional errors in judgment that cluster consistently in specific domains and directions, as opposed to random noise
Bias blind spot
the phenomenon where people readily identify biases operating in others while insisting that their own judgments are objective, with no correlation to cognitive ability or education
Intellectual humility
the measurement practice of accurately aligning confidence with actual competence, characterized by recognizing the fallibility of personal beliefs and appropriately attending to limitations in evidentiary basis and one's own knowledge acquisition and evaluation capabilities
Metacognition
the cognitive capacity to monitor, evaluate, and adjust one's own perceptual and reasoning processes in real-time for improved decision-making
Context determines meaning
the relationship between information and context is the source of meaning, not the information itself
Context Identification
the deliberate cognitive practice of explicitly recognizing and naming the current situational framework before interpreting information or making decisions, which involves asking systematic questions about environment, role, recent events, goals, and imported assumptions to avoid premature cognitive commitment
Premature Cognitive Commitment
the cognitive bias where individuals lock in an interpretation based on the context of first exposure and fail to revisit or question that context even when it changes, resulting in persistent misinterpretation of information despite new evidence or context shifts
Context loading
the deliberate cognitive process of preparing to operate within a specific frame of reference by closing previous context, creating transition gap, and explicitly orienting to new context, which requires 3-6 minutes per switch to avoid degraded performance
Decision Context Record
a structured written documentation format that captures at the moment of choice the specific forces, constraints, emotions, information, uncertainties, and alternatives active in a decision, along with expected consequences and confidence level, to prevent hindsight bias from distorting the original reasoning and enable accurate future evaluation
Cultural context
the set of invisible assumptions, values, interpretive frameworks, and operating systems that are absorbed unconsciously from one's social environment and fundamentally shape perception, cognition, and behavior in ways that feel natural and universal but are actually specific to one's cultural background and differ systematically from other cultural systems
Temporal discounting
the systematic psychological tendency to perceive future consequences as less vivid, concrete, and emotionally salient than present ones, resulting in diminished motivation to act on future outcomes
Emotional context
the emotional state that becomes fused with perception and memory, shaping what is encoded, retrieved, and interpreted rather than simply filtering incoming data
Affect-as-information
the cognitive process where people use their current emotional state as evidence or information about the world, even when that emotional state is unrelated to the judgment being made
Context collapse
the structural phenomenon where digital communication channels strip away the contextual cues (tone, gesture, shared history, audience boundaries) that normally enable accurate meaning construction in face-to-face interaction
Illusion of transparency
the cognitive bias where speakers systematically overestimate how clearly their intended meaning is conveyed to listeners, because they project their own internal knowledge onto their audience without accounting for the gap between what they know and what the listener can perceive
Fundamental attribution error
the cognitive bias that leads people to overattribute others' behavior to personality traits while underweighting situational factors that could explain the same behavior
Social context
the environmental and interpersonal conditions surrounding belief formation that systematically alter the conclusions drawn from identical information based on the presence and influence of others
Historical context
the temporal information and causal understanding of past decisions, events, and their outcomes that shapes current perception and constrains available options by embedding past experiences in decision-making infrastructure
Path dependence
the phenomenon where past decisions and historical constraints systematically limit current and future options by creating self-reinforcing structures and accumulated investments that make alternative paths economically or practically inaccessible
Transfer-appropriate processing
the cognitive theory that memory performance depends on matching the type of cognitive processing used during encoding and retrieval, with effective retrieval occurring when the processing mode at encoding matches the processing mode at retrieval rather than just semantic depth
Common ground
the shared mutual knowledge, beliefs, and assumptions between speaker and listener that must be actively constructed and maintained for successful communication to occur
Context
a frame — a set of assumptions, rules, and interpretive lenses that determine how you process information and what counts as relevant
Context design
the practice of engineering environmental cues, defaults, and friction points to make desired behaviors more likely and undesired behaviors less likely, operating through the principle that behavior is a function of person and environment.
Decision documentation
the practice of recording the full reasoning context around a decision including alternatives considered, information available, optimization criteria, and conditions for revisiting before the outcome overwrites the reasoning
Cognitive defusion
the process of creating psychological distance between the self and internal experiences (thoughts, emotions, sensations) such that the experiencer can observe these states as objects rather than being fused with them as identity or environment
Affect labeling
the specific cognitive act of assigning precise linguistic categories to emotional experiences, which recruits prefrontal regulatory circuits and reduces amygdala activity through the process of classification and differentiation
