Purpose and description
Enable an agent to recognise and assess surprise by recording whose expectations were disrupted, what changed, how the disruption was experienced or inferred, and which responses are appropriate.
Surprise is a response to an event that violates a person's expectations, commonly involving interrupted ongoing processing, redirected attention, and reassessment of the event or prior expectations.
It can be Elicit the expected and encountered outcomes without supplying an expectation on the experiencer's behalf.; Compare surprise reports across experiencers while preserving their different prior knowledge.; Assess whether available evidence supports surprise, novelty, uncertainty, startle or an unresolved combination.; Offer an explanation or time to reassess when the experiencer indicates that either would help.; Record whether the episode changes a belief, decision or intended action.; Identify when further probing would be unwelcome and stop or defer it..
Distinguishing features
Identify an occurrence and an expectation it apparently disrupted; unfamiliarity alone supports novelty but does not establish surprise.
Distinguish being unsure beforehand from encountering something unexpected: uncertainty can exist without a surprise episode.
Check whether evidence supports surprise beyond a reflexive startle; abrupt movement or sound alone does not establish violated expectations.
Separate unexpectedness from pleasantness: a welcome and an unwelcome occurrence can each be described as surprising.
Distinguish an event called a 'surprise' by its organiser from surprise actually reported or otherwise supported in its recipient.
Scope
+ The experiencer, triggering occurrence and context of a particular surprise episode
+ Explicit, implicit or reconstructed expectations and their apparent violation
+ Competing interpretations of surprise as emotion, appraisal, orienting response or belief revision
+ Reported experience, observable responses and uncertainty in attribution
+ Resolution of the discrepancy and resulting changes in beliefs or action
- Planning and delivering surprise parties, gifts, attacks or other deliberately unexpected events
- General models of emotion, attention, perception and memory
- Novelty, uncertainty and prediction error without an attributed surprise episode
- Mathematical information content or Bayesian updating considered independently of an experiencer
- Clinical assessment of persistent distress or altered cognition
Characteristics
- Experiencer
- Person or other proposed experiencer; attribution basis required An occurrence can violate one experiencer's expectations while matching another's.
- Triggering occurrence
- Event, observation, discovery, omission or internally generated realisation Locates what the episode concerns, including an expected event failing to occur.
- Expectation basis
- Explicit prediction, stated belief, habitual expectation, situational assumption, retrospective reconstruction or unknown Separates prior evidence of expectation from explanations constructed after the event.
- Expected versus encountered outcome
- Paired descriptions with relevant discrepancy and time reference Makes the alleged expectation violation inspectable.
- Interpretive account
- Emotion, appraisal, orienting response, belief revision, combined account or unresolved; source and proponent recorded Prevents one theoretical interpretation from silently becoming the definition.
- Reported surprise intensity
- Instrument-specific rating with scale anchors, reporting time and respondent Allows comparison where the measurement method supports it without inventing a universal unit.
- Experienced valence
- Pleasant, unpleasant, mixed, neutral, changing or unreported Keeps the assessment of unexpectedness separate from whether the outcome is welcome.
- Episode status
- Reported as ongoing, reported as resolved, retrospectively reported, externally inferred, disputed or unknown Distinguishes current experience from retrospective accounts and observer attribution.
- Belief revision
- Prior and subsequent belief records, including no documented change Records what the experiencer learned without assuming that every surprise produces learning.

Expectation disruption Reconstruct the relationship between what was anticipated and what was encountered.
Surprise attribution needs a specific discrepancy and an experiencer-relative expectation.
Prior expectation
Establish the content and evidential basis of the expectation.
Expectation evidence
Record whether the expectation was documented beforehand, elicited afterward or inferred by an observer.
- What did the experiencer expect, including anything taken for granted rather than explicitly predicted? definition
- What evidence places that expectation before the triggering occurrence? provenance
Encountered discrepancy
Locate the occurrence or omission that apparently contradicted the expectation.
Discrepancy content
Describe the relevant difference without equating every mismatch with experienced surprise.
- Which feature of the occurrence, or which failure to occur, departed from the expectation? definition
- What supports an experienced surprise episode beyond the existence of a prediction mismatch? boundary
Sense and interpretation Make the intended sense and theoretical commitments explicit.
Everyday surprise, psychological accounts and formal surprise measures need not identify the same instances.
Conceptual accounts
Record how a cited account defines surprise and what it requires.
Account commitments
Treat emotion, appraisal, orienting and belief revision interpretations as alternatives to investigate rather than settled equivalents.
- Which account is being used, who advances it, and what source supplies its definition? provenance
- Does that account require conscious feeling, violated expectation, attention change, belief revision or another criterion? definition
Neighbouring phenomena
Test possible confusion with novelty, startle, uncertainty and formal unexpectedness.
Instance boundaries
Record which competing labels fit the evidence and where a distinction remains unresolved.
- Could the evidence be explained by novelty, startle or uncertainty without establishing surprise? boundary
- If a probability-based score is supplied, what connects its reference distribution to this experiencer's expectations? measurement
Episode evidence Record how surprise is reported, observed and tracked through time.
An unexpected event, expressive behaviour and a reported experience provide different grounds for attribution.
Attribution and expression
Separate the experiencer's account from behavioural observations and third-party interpretations.
Converging or conflicting evidence
Preserve agreement and disagreement among reports, expressions and contextual evidence.
- Who reports surprise, and what was directly said or observed rather than interpreted? provenance
- Do self-report and observed behaviour agree, and what remains uncertain if they do not? measurement
Intensity and course
Describe the episode's reported strength, timing and changing pleasantness.
Temporal profile
Record onset, persistence and resolution only to the precision supported by the evidence.
- When was surprise first noticed and last reported, and how were those times established? measurement
- How were intensity and valence assessed, and did either change as the occurrence became understood? measurement
Sensemaking and response Track attempts to explain the discrepancy and choose a response.
An agent needs to distinguish unresolved surprise from an understood occurrence and respond to the experiencer's needs.
Explanation and updating
Record candidate explanations and any documented revision of expectations.
Discrepancy resolution
Distinguish accepting an explanation, revising a belief and merely ceasing to express surprise.
- What explanation, if any, does the experiencer accept for the unexpected occurrence? definition
- What evidence shows a changed expectation rather than only a reduced outward response? measurement
Appropriate assistance
Connect the episode to requested clarification, reassessment or a pause.
Response choice
Choose assistance using the experiencer's expressed needs and the practical consequences of the discrepancy.
- Would the experiencer welcome clarification, supporting evidence, time to process or no further discussion? action
- Does the unexpected information require revisiting a pending decision, and which assumption should be checked first? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Check these first
Recalled without web access and unsourced; every item is a lead to verify.
- The sense is unrecorded; this description covers psychological surprise, not a deliberate act of surprising someone or a military tactic.
- Theories differ on whether surprise is a basic emotion, a cognitive response, or a combination of processes.
- Pleasant, unpleasant, and neutral surprise are descriptive distinctions; their status as separate kinds is not universally agreed.
- Which of these check these first hold for the sense of surprise this model covers, and on what evidence? provenance

- Affectively neutral surprise
- Which of these kinds and varieties hold for the sense of surprise this model covers, and on what evidence? provenance
Real-world use
Recalled without web access and unsourced; every item is a lead to verify.
- Psychological experiments use unexpected outcomes to study attention, expectations, learning, and memory.
- Narrative and performance use violated expectations in plot twists, jokes, and reveals.

Failure modes and hazards
Recalled without web access and unsourced; every item is a lead to verify.
- Treating an unlikely event as necessarily surprising without establishing the person's expectations.
- Inferring subjective surprise solely from facial expressions or physiological responses.
- Conflating surprise with fear, startle, or general arousal.
- Unexpected events can interrupt ongoing tasks and delay effective action in safety-critical settings.
- Treating mathematical surprisal as a direct measurement of experienced emotion.
- Which of these failure modes and hazards hold for the sense of surprise this model covers, and on what evidence? provenance
Regional variation
Recalled without web access and unsourced; every item is a lead to verify.
- Language and cultural display norms can affect how surprise is described, expressed, and interpreted.
- Which of these regional variation hold for the sense of surprise this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Startle - Startle is a rapid defensive reflex to abrupt stimulation; surprise concerns violated expectations and can occur without an abrupt stimulus.
- Fear - Fear concerns perceived threat; surprise concerns unexpectedness and can be pleasant or neutral.
- Novelty - Novelty concerns unfamiliarity; a novel event can be expected, and a familiar event can occur unexpectedly.
- Prediction error - Prediction error is a discrepancy between predicted and observed outcomes; it need not produce a conscious experience of surprise.
- Surprisal - Surprisal is a mathematical quantity determined by an outcome's assigned probability; subjective surprise also depends on psychological processing and context.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of surprise this model covers, and on what evidence? provenance
What the second pass must settle
- Which reference accounts should anchor this registry entry, and where do their criteria for an instance of surprise disagree?
- Should conscious experience be required, and what evidence would justify attribution to nonverbal humans, nonhuman animals or artificial agents?
- Which measures distinguish experienced surprise from novelty, arousal and startle across the intended contexts?
- How should expectations reconstructed after an event be represented when no prior expectation record exists?
- When should successive unexpected discoveries count as one continuing episode rather than several separate surprises?
