Core Idea¶

Information scent is the structural pattern in which an agent navigating a partially-known space uses local cues at decision points — link text, snippet previews, headings, signage, smell, the shape of the next move — to estimate the probability that following this path leads to the goal, and updates its traversal accordingly. The cues are proximate; the goal is distal; the structural commitment is that the agent acts on the predicted value of the path rather than on direct evidence of the goal. When the scent is strong — cues reliably indicate goal proximity — traversal is efficient; when the scent is weak or misleading — cues uninformative or systematically biased — the agent wastes effort or abandons.

The pattern travels because the underlying problem — exploring a space too large to enumerate, choosing the next move from local evidence about which paths are valuable — recurs in any substrate where an agent navigates by predictive cues rather than direct goal-perception. Stripped of its origin vocabulary, the pattern reads: agents traverse spaces by reading cues that predict the value of going further; cue quality determines traversal efficiency; cue manipulation reshapes traversal. Three structural facts the prime forces into view. The cue is not the goal — scent is predictive of the goal's location, not the goal itself, so agents can be deceived by strong cues that do not lead to the goal, and can miss real goals hidden behind weak scent. Scent shapes traversal economics — the cost of following a path is paid up front while the value is realized only at the destination, so the agent uses scent to keep expected-value-per-step positive, and sustained weak scent leads to abandonment. And scent quality is a design lever — wherever cue quality is partially under designer or environmental control, traversal efficiency is engineerable, and the same behavior can be made efficient or inefficient depending on whether cues correlate with destination value.^[1]

How would you explain it like I'm…

Follow The Cookie Smell

When you smell cookies, you follow the smell to find them in the kitchen — the smell isn't the cookie, but it tells you which way to go. Looking for something, you follow signs that *hint* you're getting warmer, like signs at a zoo pointing toward the lions. If the signs are good, you find it fast; if the signs are confusing, you wander around. Information scent is following the hints that say 'this way is probably right.'

Getting Warmer Clues

Information scent is how you pick your next step when you're searching a place too big to check all of it — a website, a library, a maze. At each choice you read little clues nearby (a link's words, a sign, a heading, a smell) and guess: does *this* path probably lead to what I want? You follow the clue that smells strongest, then check again at the next fork. When the clues are good, you reach the goal quickly; when they're weak or misleading, you waste effort or give up. The big catch: the clue is *not* the goal — a strong-smelling path can still be a dead end, and the real thing can hide behind a weak clue.

Cues Predict The Path

Information scent is the pattern in which an agent navigating a partially-known space uses LOCAL cues at decision points — link text, snippet previews, headings, signage, smell, the shape of the next move — to estimate the probability that following this path leads to the goal, and updates its traversal accordingly. The cues are proximate while the goal is distal, and the structural commitment is that the agent acts on the PREDICTED value of the path rather than on direct evidence of the goal. Strong scent (cues that reliably indicate goal proximity) makes traversal efficient; weak or misleading scent makes it wasteful or causes abandonment. Three facts come into view. The cue is not the goal — scent predicts the goal's location, not the goal itself, so strong-but-wrong cues deceive and real goals hide behind weak scent. Scent shapes traversal economics — cost is paid up front per step while value arrives only at the destination, so the agent uses scent to keep expected-value-per-step positive and abandons when scent stays weak. And scent quality is a design lever — wherever cue quality is partly controllable, traversal efficiency is engineerable.

Structural Signature¶

the distal goal in a partially-known space — the decision points where paths branch — the local proximate cues at those points — the cue-to-destination-value correlation — the cost-paid-up-front-value-realized-at-destination economics — the cue-is-not-the-goal invariant that makes deception structurally possible

The pattern is present when the following components are jointly in play:

The navigating agent (the forager). A party traversing a space too large to enumerate, choosing its next move from local evidence rather than direct goal-perception.
The distal goal (the sought target). The destination the agent seeks, not directly perceptible from the current position — the sought page, shelf, ward, bug, answer.
The decision points (the branches). Locations where the path forks and a choice must be made — menu branches, signage junctions, import statements, paragraph boundaries.
The local cues (the proximate signals). Readable signals at each decision point — link text, snippets, headings, signs, smells — that the agent uses to estimate the value of going further.
The cue-to-destination correlation (the diagnostic quantity). How well the cues actually predict goal-proximity; traversal efficiency tracks this correlation, and it is often a design lever under environmental control.
The cue-is-not-the-goal invariant. Scent predicts the goal's location, not the goal itself, so strong cues can mislead and weak scent can hide real goals; wherever cues are cheaper to manipulate than destinations, the environment drifts toward deceptive scent.

Composed, these relocate global planning into per-step cue-reading: the agent keeps expected-value-per-step positive by following cues that predict downstream value, with efficiency governed by cue-destination correlation and abandonment triggered when it drops below threshold.

What It Is Not¶

Not an information cascade. information_cascade is multi-agent imitation — agents copy predecessors' choices, overriding private signals; information scent is single-agent cue-reading — one agent reads local signals predicting downstream value. The shared word "information" hides the difference between copying others and reading the environment.
Not search in general. search_and_retrieval includes exhaustive enumeration and direct retrieval; information scent is the cue-guided traversal mechanism within search that applies only when the space is too large to enumerate and the goal is not directly perceptible.
Not a signal generally. signaling and signals broadly are any value-bearing indicator; information scent is the specific subclass of local navigation cues predicting downstream value at a decision point. It is a navigation-cue, not any signal.
Not an affordance. affordance is a possibility for action the environment offers; information scent is a prediction of value for traversing a path. One says "this can be acted on"; the other says "this path is likely to pay off."
Not sensemaking. sensemaking is the global synthesis of an understanding; information scent is the cheap per-step local decision rule. A sequence of locally-good cue-follows does not compose into sensemaking, which the prime explicitly flags.
Not conformity. conformity is alignment with a group under social pressure; information scent is solitary cue-guided traversal driven by predicted destination value, not by others' expectations.
Common misclassification. Engineering predictive cues where the space is small enough to enumerate or where a direct index would serve, or expecting exhaustive coverage from an agent actually foraging by cue. Catch it by asking whether the agent can perceive the goal directly or must predict it from local signals — only the predict-from-cues case is information scent.

Broad Use¶

Human-computer interaction and information architecture. The canonical case: navigation menus, search-result snippets, breadcrumbs, and file-explorer labeling all turn on whether cues predict destination value.
Web search. Result snippets are scent-cues predicting whether a linked page contains the goal; search engineering is largely scent engineering, with the failure mode that ranking-optimization improves the scent without improving the destination.^[1]
Library and catalogue navigation. Users follow scent through controlled vocabularies, classification numbers, and finding aids; catalogue principles are partly scent design.
Wayfinding and architectural signage. Hospital, airport, and transit signage are scent systems for physical navigation, each junction a decision point with cues predicting which direction reaches the goal.
Animal foraging. The source case: animals navigate patchy environments by reading proximate cues that predict patch value, and optimal-foraging theory supplies the decision rule that information-foraging theory imported.^[2]
Codebase exploration. Developers navigate unfamiliar code by file and function names, comments, and imports — all scent cues predicting whether a path reaches the bug or feature.
Reading, journalism, and customer journeys. Headings, topic sentences, headlines, and funnel steps are scent cues predicting whether continuing yields the reader's or customer's goal; engagement-optimized media systematically degrade scent through headline-payload mismatch.^[3]

Clarity¶

Naming a navigation problem as a scent problem commits the analyst to four explicit claims that "users got lost" or "engagement was low" leave implicit: there is a goal the agent is seeking, there is a space of paths between current position and goal, there are cues at decision points the agent reads, and the cues' correlation with destination value is the diagnostic quantity. Each is contestable in a given case, and each suggests a different intervention. A failure caused by goal-ambiguity differs from one caused by missing cues, which differs again from one caused by misleading cues — and the scent label keeps these distinctions live where a flat "lost" reading collapses them.

The label also makes a recurrent pathology legible: cues that are easy to optimize without optimizing the destination produce deceptive scent. The deception is structurally predictable from the gap between cue and goal — whenever the cue is cheaper to manipulate than the destination, the equilibrium drifts toward deceptive scent, which is the common origin of clickbait, ranking games, misleading product labels, and false signage.^[1] Naming the bet the cue makes reveals when it is about to be called.

Manages Complexity¶

Information scent compresses an intractable global planning problem — which path through this enormous space leads to my goal? — into a tractable local decision rule: which cue at the next branch predicts highest value? This is how agents navigate spaces too large to search exhaustively: planning is relocated into per-step cue-reading, which is far cheaper than computing whole paths. The agent never holds the full space; it holds only the next branch and a prediction about each option's value.

The compression also makes the navigation pattern legible to designers and analysts. A flat "users got lost" observation decomposes into a four-stage process — goal, path, cue, judgment — and failures localize: was the goal unclear, the path absent, the cue missing, the cue misleading? Each failure mode has a distinct intervention. Managing complexity here is double: the agent's planning cost collapses to local cue-reading, and the designer's diagnostic cost collapses to locating which stage of the scent process failed.

Abstract Reasoning¶

Information scent supports several inferences. Cue-quality inference: traversal efficiency tracks the correlation between cues and destination value, so improving link text, signage, snippets, or headings improves traversal. Deceptive-scent inference: any environment where cues are cheaper to manipulate than destinations drifts toward deceptive scent — the structural origin of clickbait, ranking games, and false storefronts. Abandonment-threshold inference: agents abandon paths when expected-value-per-step drops below a threshold, so sustained weak scent produces abandonment even when the goal is a few steps further, and engagement systems must keep scent above threshold or lose the agent. Cue-blindness inference: agents who do not know what to look for — novices in a domain — read cues poorly and traverse inefficiently, so onboarding and apprenticeship are partly about teaching the cue vocabulary. And patch-leaving inference: foragers leave a patch when local scent drops below the value of switching, and the optimal-foraging marginal-value theorem ports directly into multi-tab browsing and multi-document reading.^[2]

Reasoning at this level asks, of any traversal of a large space: what is the goal in cue-matchable terms, where are the decision points, what cues sit at them, and how well do those cues correlate with destination value? These questions distinguish information scent from search broadly (scent is the cue-guided traversal mechanism within search, absent in exhaustive enumeration and direct retrieval), from signal generally (scent is the specific subclass of local navigation cues predicting downstream value), from affordance (a possibility for action versus a prediction of value), from sensemaking (the global synthesis, which may use scent but is not the whole of it), and from information cascade (per-agent cue-reading versus multi-agent imitation, despite the shared word).

Knowledge Transfer¶

The pattern transfers as a substrate-neutral diagnostic and intervention kit, carried by stable role mappings: the goal maps to the sought page, the right shelf, the destination ward, the bug, the answer; the decision points map to menu branches, catalogue cross-references, signage junctions, import statements, paragraph boundaries; the cues map to link text, snippets, signs, breadcrumbs, smells, labels; and the cue-destination correlation maps to how well any of these actually predicts goal-proximity. With these fixed, a search engineer, a wayfinding designer, and a developer-tools builder recognize one another's problem.

Documented transfers run in both directions and form the strongest part of the case. The original transfer was the explicit port of optimal-foraging theory into HCI, carrying the marginal-value theorem and diet-breadth model with their predictions intact — a paradigm case of structural recognition driving knowledge transfer.^[1] From there the frame ported into search-engine design (snippet length, query-term highlighting, breadcrumb-style URLs), into developer tools (jump-to-definition and find-references justified as scent-improvement interventions with measured traversal-time savings), and into hospital-wayfinding studies where cue-quality interventions measurably reduce disorientation.^[3] Across all of these the menu is constant: clarify the goal vocabulary, improve cue correlation with destination, reduce ambiguous or misleading cues, teach the cue vocabulary to novices, protect cue integrity against incentives that decouple cue from destination, and monitor abandonment as a scent-quality indicator. A hospital-website team that relabels specialty links from internal department names to patient goal-vocabulary — without adding content — is improving scent, structurally identical to a search engine improving snippet generation or a forager relocating to a richer patch. The transfer is robust because the strip-the-jargon residue — traverse a space by reading cues that predict the value of going further — survives into search, wayfinding, code navigation, reading, and animal foraging alike, and the confirmed bidirectional movement between foraging biology and HCI is itself evidence that the structure, not the vocabulary, is what carries.

Examples¶

Formal/abstract¶

Animal foraging under optimal-foraging theory is the source case and the cleanest formal instance, because the decision rule is exact. A foraging animal in a patchy environment is the navigating agent; the distal goal is a rich food patch it cannot see from its current position; the decision points are the junctions in its path where it chooses which way to move; the local cues are proximate signals — a scent gradient, the density of tracks, the visual texture of vegetation — that the animal reads to estimate the value of going further. The cue-to-destination correlation is the diagnostic quantity: when scent reliably tracks patch richness, traversal is efficient; when it does not, the animal wastes energy. The cost-paid-up-front-value-realized-at-destination economics is exact here — each step costs metabolic energy now, while the food reward arrives only at the patch — so the animal must keep expected-value-per-step positive. The marginal-value theorem formalizes the patch-leaving decision: the forager should leave a depleting patch when the local intake rate drops to the environment's average rate, accounting for travel time.^[2] The cue-is-not-the-goal invariant is structurally live: a strong scent that does not lead to food (a decoy, a depleted patch that still smells rich) deceives the forager, and a genuinely rich patch behind weak scent goes unvisited. The transfer that founded the HCI field was the literal port of this machinery — the marginal-value theorem and diet-breadth model carried intact — into information foraging, where a person reading multiple browser tabs "leaves the patch" by exactly the same rule.^[1]

Mapped back: The animal is the forager-agent, the food patch is the distal goal, the path junctions are the decision points, the scent gradient is the local cue, the scent-richness correlation is the diagnostic quantity, and the patch-leaving rule is the abandonment-threshold inference the prime names.

Applied/industry¶

Web search and hospital wayfinding instantiate the identical cue-guided-traversal structure in engineered substrates. A web searcher is the navigating agent; the distal goal is a page containing the answer; the decision points are the result listing and each page's links; the local cues are the result snippets, titles, and URL breadcrumbs that predict whether clicking reaches the goal. Search engineering is largely scent engineering: snippet generation, query-term highlighting, and readable URLs all raise the cue-to-destination correlation. The prime predicts the field's signature pathology — deceptive scent: because a snippet is cheaper to manipulate than the destination page's actual quality, the environment drifts toward clickbait and ranking games, where strong cues lead to weak destinations, exactly the cue-is-not-the-goal invariant exploited. The diagnostic this enables is sharp: a search experience where users click and immediately bounce has a cue-destination mismatch, not a relevance-ranking failure per se. Hospital wayfinding runs the same anatomy physically: a visitor seeking a ward is the agent, the decision points are corridor junctions, the cues are signs, and studies show that relabeling signage from internal department names to patient goal-vocabulary — without changing the building — measurably reduces disorientation by raising cue correlation.^[4] The intervention is identical in kind: a hospital team relabeling "Cardiology" junction signs to "Heart Center / Chest Pain" is improving scent, structurally the same move as a search engine improving its snippets, and both target the cue-blindness of novices who do not yet know the domain's internal vocabulary.^[4]

Mapped back: Searcher and hospital visitor are the agents; the answer page and the ward are distal goals; result snippets and corridor signs are local cues; click-then-bounce and corridor disorientation are low cue-destination correlation; and clickbait is the deceptive-scent failure the prime predicts wherever cues are cheaper to manipulate than destinations.

Structural Tensions¶

T1 — Proximate Cue versus Distal Goal (the founding gap). Scent predicts the goal's location; it is not the goal — and that gap is precisely what makes deception structurally possible. The agent acts on predicted value, so a strong cue with a weak destination misleads and a rich destination behind weak scent goes unvisited. The failure mode is conflating cue quality with goal attainment: optimizing snippets, headlines, or signage and declaring success while destinations stay poor. Diagnostic: measure what happens after the agent follows the cue — bounce, backtrack, abandonment — not just whether the cue was attractive; click-then-leave is the signature of cue-destination divergence.

T2 — Cue Integrity versus Optimization Pressure (sign/incentive). Wherever a cue is cheaper to manipulate than the destination it predicts, the environment drifts toward deceptive scent — clickbait, ranking games, false storefronts — because optimizing the cue pays without improving the goal. The same design lever that improves navigation becomes the vector of its corruption. The failure mode is treating scent quality as static while incentives steadily decouple cue from destination. Diagnostic: ask whether anyone benefits from the cue overstating the destination; if cue-faking is cheap and rewarded, assume scent is degrading and audit cue-destination correlation over time, not once.

T3 — Per-Step Cost versus Destination Value (temporal economics). Cost is paid up front at each step while value is realized only at the destination, so the agent navigates on expected-value-per-step and abandons when that drops below threshold — even when the goal is a few steps further. The economics, not the goal's existence, governs traversal. The failure mode is losing an agent who was nearly there because sustained weak scent pushed expected value below the abandonment line. Diagnostic: monitor abandonment as a scent-quality indicator and ask whether weak intermediate cues are masking near goals; keep per-step scent above threshold along the whole path, not just at the start and end.

T4 — Expert Cue-Reading versus Novice Blindness (scopal/who). Traversal efficiency assumes the agent knows what to look for, but novices cannot read cues they lack the vocabulary for — the same well-designed scent that guides an expert is invisible to a beginner. Cue quality is relative to the reader. The failure mode is labelling navigation with internal or domain-expert vocabulary (department names, jargon menus) that carries no scent for the actual newcomer users. Diagnostic: ask whether cues are expressed in the agent's goal-vocabulary or the designer's; if novices cannot map their goal onto the cues, relabel toward their terms (the "Cardiology" → "Heart Center / Chest Pain" move) rather than adding content.

T5 — Local Cue-Reading versus Global Sensemaking (scalar, local vs global). Scent relocates planning into cheap per-step decisions, which is its power — but a sequence of locally-optimal cue-follows does not compose into a globally optimal path or a synthesized understanding. The greedy local rule can strand the agent in a dead end that looked good one step at a time. The failure mode is mistaking efficient local traversal for successful sensemaking, or designing only for next-click appeal while the overall journey incoheres. Diagnostic: ask whether following the strongest local cue at each branch actually reaches the goal, or whether the agent needs a global view (overview, map, breadcrumb) that scent alone cannot supply.

T6 — Cue-Guided Traversal versus Exhaustive Search (boundary of the prime). Information scent is the mechanism within search that applies when the space is too large to enumerate; it is absent in exhaustive enumeration and in direct retrieval where the goal is perceptible without cues. The shared word "search" hides the boundary. The failure mode is importing scent reasoning where it does not belong — engineering predictive cues for a space small enough to list outright, or where a direct index would serve — or, inversely, expecting exhaustive coverage from an agent that is actually foraging by cue. Diagnostic: ask whether the agent can perceive the goal directly or must predict it from local signals; only the predict-from-cues case is information scent, and only there do its deception and abandonment dynamics apply.

Structural–Framed Character¶

Information scent sits on the structural side of the structural–framed spectrum, with a mixed-structural label and a low aggregate of 0.3 — a medium-neutral cue-guided-traversal mechanism that wears HCI/foraging-theory vocabulary without depending on it. Two diagnostics read fully structural and three sit at the mid-point, placing it just inside the structural half.

Evaluative weight and human-practice-boundedness both score 0.0. Reading local cues that predict the value of going further carries no approval or disapproval — strong scent and deceptive scent are both instances of the same value-neutral mechanism, neutral until you specify whether cues correlate with destination value. And it is emphatically not human-practice bound: the source substrate is animal foraging, where a non-human forager reads scent gradients and track density under the optimal-foraging marginal-value theorem, with no human practice anywhere in the structure. The three mid-scale criteria all reflect the same fact: an HCI/information-foraging origin that names the mechanism without rooting it. Vocabulary half-travels — the "scent" lexicon is foraging-and-HCI-born, yet the underlying move, traverse a space by reading cues that predict the value of going further, is recognized, not imported, when it reappears in web search snippets, hospital wayfinding signage, codebase navigation, and reading. The entry stresses that the field was founded by literally porting optimal-foraging theory into HCI and that transfer runs bidirectionally between foraging biology and interface design — strong evidence the structure, not the vocabulary, is what carries. Institutional origin is 0.5 because the HCI provenance colors the prime without making it depend on any institution. Import-versus-recognize is likewise 0.5: invoking it mostly recognizes a cue-prediction-traversal structure already present in any navigation of a too-large space, with only a light foraging-theory overlay. The honest reading, matching the 0.3 grade, is a substrate-neutral cue-guided-traversal mechanism lightly colored by its HCI home — structural, with a modest framed tinge.

Substrate Independence¶

Information scent is a strongly substrate-independent prime — composite 4 / 5 on the substrate-independence scale, and unusually among framed-origin primes its case rests on confirmed bidirectional transfer. Its domain breadth is high (4 / 5): the cue-guided-traversal pattern recurs with the same structural force across human-computer interaction and information architecture (the canonical menus, snippets, breadcrumbs), web search (snippets as scent-cues), library and catalogue navigation, wayfinding and architectural signage (hospital, airport, transit), animal foraging (the source case, governed by optimal-foraging theory), codebase exploration (file and function names as cues), and reading, journalism, and customer journeys — spanning a physical-biological substrate (animal foraging) and engineered informational ones. Its structural abstraction is high (4 / 5): the signature is stated in medium-neutral terms (navigating agent, distal goal, decision points, local cues, cue-destination correlation, cost-up-front economics), and the marginal-value theorem and diet-breadth model carry across without domain-specific commitment. Transfer evidence is concrete and documented (4 / 5), and this is the prime's strongest leg: the field was founded by literally porting optimal-foraging theory from biology into HCI with the marginal-value theorem intact, and the frame then ported into search-engine design, developer tools (jump-to-definition justified as scent-improvement with measured traversal-time savings), and hospital-wayfinding studies with measured disorientation reduction — a confirmed bidirectional movement between foraging biology and interface design that is itself evidence the structure, not the vocabulary, carries. The only thing holding the composite shy of the top is the HCI/foraging-theory home vocabulary (the "scent" lexicon), which must be stripped to its residue to travel — but the underlying cue-prediction-traversal mechanism is genuinely medium-neutral.

Not to Be Confused With¶

Information scent's nearest neighbour by embedding is the information_cascade, and the shared word "information" makes the confusion almost automatic — yet the two describe opposite epistemic situations. An information cascade is a multi-agent imitation dynamic: agents observe the choices of those who went before and copy them, rationally overriding their own private signals once enough predecessors have chosen the same way, so the population converges on a choice that may rest on little actual information. The mechanism is social — the cue an agent reads is what others did. Information scent is a single-agent mechanism: one navigator reads local environmental cues (link text, snippets, signage, a scent gradient) that predict the value of going further toward a goal, and acts on that prediction. The cue an agent reads is the environment's signal about the destination, not other agents' behavior. The distinction is load-bearing because the failure modes and remedies diverge entirely. Cascades fail by herding on a possibly-wrong consensus, and are countered by surfacing private signals, decorrelating decisions, or revealing the thinness of the chain. Information scent fails by deceptive cues (strong scent, weak destination) or abandonment (weak scent masking a near goal), and is countered by improving cue-destination correlation, relabeling toward the agent's vocabulary, and monitoring bounce/abandonment. A practitioner who reads a navigation problem as a cascade will look for who-copied-whom when the actual issue is whether the local cues predict destination value; one who reads a cascade as scent will tune cues when the problem was social imitation overriding private information. The diagnostic: ask whether the agent is reading other agents' choices or the environment's local signals.

Information scent must also be held apart from sensemaking, with which it is conflated because both concern an agent finding its way through an unclear, large information space toward understanding. The structural difference is local versus global and traversal versus synthesis. Information scent is a cheap per-step local decision rule: at each branch, follow the cue that predicts the highest downstream value, relocating planning into a sequence of next-move judgments the agent can make without holding the whole space. Sensemaking is the global synthesis of a coherent understanding from dispersed, ambiguous information — integrating pieces into a frame, not merely choosing the next click. The prime is explicit that the two are not the same and that one does not reduce to the other: a sequence of locally-optimal cue-follows does not compose into a synthesized understanding or even a globally optimal path; the greedy local rule can strand the agent in a dead end that looked good one step at a time. Sensemaking may use information scent (foraging for the pieces it will integrate) but is not exhausted by it — it additionally requires the global integration, overview, or map that scent alone cannot supply. The distinction matters because designing only for next-click appeal (strong local scent) can produce an incoherent overall journey, and mistaking efficient local traversal for successful sensemaking leaves the synthesis undone. A practitioner who conflates them optimizes per-branch cues and declares the understanding achieved, when the agent has foraged efficiently but never made sense of the whole.

These distinctions matter because each frame points at a different intervention. A cascade calls for decorrelating choices and surfacing private signals; an information-scent problem calls for improving cue-destination correlation and the agent's cue vocabulary; a sensemaking problem calls for tools of global synthesis — overviews, maps, integrative framing. Reading scent as a cascade hunts for imitation that was not the mechanism; reading sensemaking as scent ships a string of good next-clicks that never cohere into understanding.
