The irreducible epistemic atoms underlying the curriculum. 4,828 atoms across 8 types and 2 molecules
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
