Return & recommendation language, month 2 onward
EDI — Experience Depth Index
What it measures: Emotional longevity, memory durability, imprint.
Meaning: Not “liked it” but remembered it weeks later.
Implications / Action: If EDI is low, you need one moment that lands — a signature welcome, dish, ritual or goodbye. Stop changing everything; anchor one emotional memory.
CSI — Contact & Service Index
What it measures: Warmth, pacing, table-reading, tone.
Meaning: Service that supports the meal rather than performs over it.
Implications / Action: If CSI dips, train staff on silence, distance and timing — service reduction, not enthusiasm inflation.
FLI — Friction Load Index
What it measures: Micro annoyances: waiting, noise, booking pain, table squeeze, payment.
Meaning: Friction is the tax on joy.
Implications / Action: Fix the one biggest friction first (e.g. online booking pain, door bottleneck). Removing one friction often adds more delight than adding one dish.
MII — Memory Impact Index
What it measures: What they remember vs what you think matters.
Meaning: Guests recall moments, not menus.
Implications / Action: Build one tiny ritual, a final bite, a handwritten card, a farewell phrase. Drop the performative flourish; elevate the quiet exit.
WOMI™ — Word of Mouth Index
What it measures: Return, remark, remember — not review volume.
Meaning: A silent army of unpaid ambassadors.
Implications / Action: Spot dishes guests bring others back for and do not change them. Stability fuels referral loops more than novelty.
CDI — Chef Discipline Index
What it measures: Technique repetition under fatigue and full covers.
Meaning: Saturday is the exam; discipline is consistency.
Implications / Action: If CDI slips, shrink the menu, reduce variation, cut ego flourishes. Consistency before creativity.
CFI — Composite Friction Index
What it measures: Total stack of small pains.
Meaning: One annoyance is nothing. Three is erosion.
Implications / Action: Audit entry → seating → ordering → paying. Remove one point in each micro-journey, not one big “experience overhaul.”
TXT — Textual Truth Index
What it measures: Authenticity of language vs fabricated praise.
Meaning: Real memory is textured; fake memory is vague.
Implications / Action: Stop asking for reviews. Start creating experiences that write themselves. Detail appears when life happens, not when you beg for stars.
HBI — Harmonic Balance Index
What it measures: Food, room tone, pacing, expectation alignment.
Meaning: Harmony is emotional ease, not wow.
Implications / Action: If room tone fights the food, tweak lighting, sound, spacing — not the chef. Most “food problems” are room problems misdiagnosed.
SVI — Seasonal Veracity Index
What it measures: Ingredient truth, calendar honesty.
Meaning: Not seasonal ink — seasonal flavour.
Implications / Action: If SVI falls, remove “seasonal” words until the dish tastes like its month. Swap bragging for restraint.
Sample output
“Delicious language +8% vs last period.”
“Noisy mentions down since the terrace closed.”
“Rushed spikes Friday 18:00–20:00.”
Authenticity
We don’t delete hype — we neutralise it.
Empty praise doesn’t count
5-star bursts ignored unless detailed
Vague “amazing!” contributes zero
If it says nothing, it shapes nothing.
Here are the main potential biases. You’re right to ask, these matter.
Geographic / Cultural Bias
-
US-centric language weighting (“awesome,” “great service”) may be over-valued vs European restraint.
-
Belgian / French / Dutch understatement can be mistaken for neutrality.
-
British-style politeness can read as positive when it’s actually disappointment (“quite nice,” “not bad”).
Risk: Overestimating satisfaction in cultures where enthusiasm is rarely explicit.
Gendered Language Bias
- Women’s emotional language may be coded as “subjective” or “soft.”
- Male-coded bluntness may be read as more “credible.”
- Sentiment tools often misread warmth (often attributed to women) as less authoritative.
Risk: Overweighting terse criticism, underweighting relational praise.
Hospitality Norm Bias
- Overvaluing “speed” and “service efficiency” (US marker)
- Undervaluing lingering, ritual, and host-style welcome (Persian, Indian, Mediterranean, European traditions)
Risk: reading calm, slow, intimate as “inefficient” instead of “intended.”
Language Fluency Bias
- Reviews written in imperfect English may be treated as lower-signal.
- Non-native phrasing can trigger false sentiment (e.g., “food was too much” = generous, not negative).
Risk: missing strong praise because syntax isn’t “standard.”
Hyperbole Weighting Bias
- Some cultures use intensity (“incredible,” “amazing!”) as basic politeness.
- Others use faint praise (“lovely”) as highest compliment.
Risk: Italian/Arabic/US enthusiasm gets overweighted; Belgian/French nuance underweighted.
Star vs Text Conflict Bias
- AI tends to anchor on star numbers even when told not to.
- A 3-star with glowing text can be mislabeled as “mixed.”
Risk: Emotional memory is undervalued if the star is mediocre.
Negativity Overfocus Bias
- Algorithms are built to detect problems.
- They can amplify mild complaints and downgrade quiet satisfaction.
Risk: false impression of “decline” simply because negatives are easier to tag than affection.
Middle-Class Taste Bias
- Trend-driven Western markers (artisanal, seasonal, tasting menu) may be mistaken as universal standards.
- Comfort, heritage, and familiarity can be under-credited because they’re not “modern dining signals.”
Risk: Reading classic dishes as safe rather than emotionally anchoring.
Trend Bias
- Preference toward what’s fashionable in reviews (ferments, sourdough, tasting menus, Nordic minimalism).
- Underweighting diasporic, familial, or everyday cuisines.
Risk: “Home cooking, generous, comforting” gets coded as pedestrian instead of beloved.
Temperature Bias
- Warmth, hosting, community, personal presence often sit outside Western rating logic.
- AI can struggle to recognise belonging as a quality metric.
Risk: Relational excellence (your true strength) gets undervalued.
How does Voice Ledgers avoid this?
We deliberately:
Ignore star ratings as anchor
Weight memory language not enthusiasm
Map cultural speech norms (Belgian, French, Persian, Indian, British)
Create silence analysis (what’s not mentioned)
Look for emotional recurrence, not adjectives
Calibrate scoring per city, not globally
Not “Is it amazing?”
But “Do they talk about it again, unprompted?”
