Evidence cases and public-path reviews

Evidence, public journeys and the questions they leave open.

Evidence cases separate a published result from Violet’s interpretation. Public Path Reviews examine public material as hypotheses, not client work or proof of failure. Both are different from Applied Projects, where Violet is used on a live problem and records its prediction before later results exist.

NHS appointment reminders

When complete information still does not produce attendance

Adding a specific missed-appointment cost reduced non-attendance in two local trials, but the trials did not establish whether cost, credibility, memory, or another mechanism caused the change.

Read the living analysis →

Violet interpretation

The essential appointment facts remained similar, but the concrete consequence may have changed Stake, credibility, memory, or why the receiver believed the number was included.

What it does not prove

The trials establish a local effect of message assignment on attendance. They did not directly establish which psychological mechanism changed.

WeChat social advertising

Why a familiar source is not equally persuasive for every decision

A friend’s endorsement increased ad clicks on average, but its effect depended on the product and relationship—and a click does not establish trust, persuasion, or benefit.

Read the living analysis →

Violet interpretation

Source is not a badge attached to a message. Its value depends on who the source is to this receiver, for this decision, in this context.

What it does not prove

A click does not establish belief, product benefit, or a durable relationship effect.

The Harris 2024 Attention Gap

What voter issue salience, campaign message allocation, and issue ownership can—and cannot—tell us about the 2024 campaign

The public record supports testing whether high issue salience became message recall and credible candidate ownership; it does not show that a communication gap caused the election result.

Read the living analysis →

Violet interpretation

The evidence does not support a simple “wrong issues” verdict. It supports a testable alignment question. A campaign can possess Substance—a policy—and allocate substantial airtime to it while still failing to produce receiver-side recall or Source ownership. Conversely, a rival can dominate ownership through repetition, prior party reputation, news context, or dissatisfaction with incumbent conditions. Violet would locate the gap by receiver group, issue, date, and channel rather than infer it from the final result.

What it does not prove

The 2024 result had many plausible causes, including economic evaluations, policy preferences, incumbency, turnout, candidate perceptions, campaign organization, media coverage, partisanship, and events outside either campaign’s control. Public ad data do not cover every channel or private exposure, survey responses are not direct measures of attention or causal effects, and issue mention does not establish comprehension. This case does not claim that a different message allocation would have changed the winner.

Headlines and accuracy prompts

Clicking, believing, and sharing are different transitions

Headlines and accuracy prompts can change different outcomes—clicking and sharing quality—so teams should optimize the exact transition they value rather than engagement in general.

Read the living analysis →

Violet interpretation

The cue that wins attention can change the transition. Clicking, judging accuracy, sharing, and benefiting are separate outcomes with different thresholds.

What it does not prove

Results from headline and sharing environments should not be treated as universal evidence for every communication context.

One Growth Plan, Four Receivers

How an intended growth signal became a credibility, security, fairness, and political-survival signal

The Growth Plan’s growth frame did not answer receivers’ different questions about fiscal credibility, household security, fairness, and political viability; the sequence does not prove that wording caused the outcome.

Read the living analysis →

Violet interpretation

The phrase “growth plan” supplied the sender’s intended frame, but receivers inferred consequences through their own jobs and priors. Substance and Source were inseparable: large fiscal changes arrived without a simultaneous Office for Budget Responsibility forecast, while the medium-term fiscal plan was deferred. High-Stake downside questions became salient before the promised growth path became credible. Repetition or rhetorical confidence could not, by itself, close that evidence gap.

What it does not prove

This sequence does not prove that wording caused the market or public reaction. Policy substance, the absence of a simultaneous independent forecast, global economic conditions, monetary-policy expectations, market structure, political priors, and later decisions all contributed. Violet’s redesign is a communication-governance hypothesis, not evidence that different presentation would have prevented the outcome.

Facebook election mobilization

When a social cue moves online expression and offline participation

In this large Election Day experiment, a message showing friends who had voted affected online behavior and validated voting more than information alone, but the result is neither universal nor an automatic ethical mandate.

Read the living analysis →

Violet interpretation

The friend cue may have changed Source, norm perception, identity relevance, and Stake at the moment of action. The effect also demonstrates why a social cue should be modeled relative to the receiver’s relationship network rather than as generic proof.

What it does not prove

This does not show that every campaign should display friends, that the same effect transfers to other elections or platforms, or that social pressure is ethically appropriate in every context.

Vaccine Reminder Messages: Why “A Vaccine Is Waiting” Performed Best in One Megastudy

Why “a vaccine is waiting for you” outperformed expert intuition

In this megastudy, repeated reminders saying a flu shot was waiting produced the strongest result, but the trial does not establish a universal vaccine message or mechanism.

Read the living analysis →

Violet interpretation

The winning message may have increased expected relevance, made availability concrete, and shifted the operative frame from abstract recommendation to an already-prepared next step. Repetition may also have improved retrieval at a convenient moment.

What it does not prove

The result belongs to the participating pharmacy population, influenza season, delivery channel, and operational context. It does not establish a universal vaccine message or explain the mechanism by outcome data alone.

Resume redesigned for a specific role

From a generic career history to a receiver-specific evidence path

Reordering only verified experience can make role fit easier for recruiters and hiring managers to evaluate, but this is a design demonstration—not evidence of improved hiring outcomes.

Read the living analysis →

Violet interpretation

The intervention should change sequence and accessibility, not invent experience. Spotlite moves role fit and verified outcomes earlier; Strain falls when evidence is grouped around the receiver’s decision; Substance remains bounded by what the candidate actually did.

What it does not prove

This is an applied demonstration, not a reported client outcome or evidence that formatting can overcome discrimination, missing qualifications, labor-market conditions, or a genuine role mismatch.

Resume screening and racialized names

Why a stronger resume does not enter a neutral receiver system

Equivalent evidence was evaluated differently when resumes carried racialized name cues, so unequal screening cannot honestly be treated as a candidate copy problem.

Read the living analysis →

Violet interpretation

Receiver-conditioned interpretation includes harmful and unjust priors. A communication framework must not redescribe discrimination as a candidate messaging failure or imply that the burden belongs entirely to the applicant.

What it does not prove

The study does not identify every mechanism behind employer decisions or establish the size of discrimination in every contemporary market. It clearly warns against attributing all resume outcomes to document quality.

Why Online-Learning Persistence Interventions Work Differently Across Courses

Why a promising intervention can weaken or reverse across contexts

Persistence interventions did not transfer consistently across courses and student contexts, so teams should re-test the local bottleneck rather than scale an average result as universal.

Read the living analysis →

Violet interpretation

A cue configuration is conditional on receiver state and context. Scaling changes the information field, population, exposure history, and often the bottleneck itself.

What it does not prove

The results do not mean behavioral interventions never work. They show that context-sensitive effects require theory, measurement, and replication across the environments where a program will operate.

Published field evidence Healthcare Updated July 30, 2026

Clinical preventive-care reminders

When the decision support appears inside the clinician’s active workflow

Preventive-care reminders placed inside order entry increased clinician ordering in one hospital system, but the bundled design does not by itself prove which feature worked or whether patients benefited.

Read the living analysis →

Violet interpretation

The reminder arrived when the decision schema and action controls were active. It increased Spotlite and immediate Stake while reducing the Strain of translating guidance into an order.

What it does not prove

The intervention combined several design features and occurred in one hospital system. Increased ordering does not by itself establish appropriate delivery, patient benefit, or transfer to modern clinical systems.

AI workplace change announcement

How “efficiency” can become a threat signal before the plan is understood

An AI announcement should state what changes, what remains uncertain, who is accountable, and how workers can question the rollout before asking them to trust an efficiency claim; the exact content depends on the real labor and governance context.

Read the living analysis →

Violet interpretation

Repeating benefits before addressing credible risk can increase mistrust. The path should clarify what is decided, what remains uncertain, who is accountable, what changes now, what does not change, and where employees can challenge or shape implementation.

What it does not prove

This is an applied demonstration, not a client result. The appropriate message depends on the actual system, labor context, governance, risks, and decisions already made.

Independent analysis

Public Path Reviews

Careful reviews of public material. They identify observable paths, competing explanations, and tests—not private performance problems or client diagnoses.

Violet’s standard

Separate the outcome from the mechanism.

A changed attendance rate, click, or share establishes a local outcome under the study conditions. It does not by itself establish attention, trust, comprehension, or benefit. Violet uses those distinctions to design the next measurement.
