FMCG research that captures what consumers feel, not what they say they think.
Consumer goods research has a structural problem: the most commercially valuable emotional signals — genuine desire, suppressed aversion, first-exposure resonance — are exactly the signals that group settings and moderated interviews cannot reach. EchoDepth captures them at the moment they occur.
The research gap
The "interesting but wouldn't buy" problem is structural, not methodological.
The scale of the problem: Approximately 80–90% of new consumer goods launches fail within 12 months of launch (Nielsen, Cambridge Innovation Advisors). The majority are preceded by research that predicted success. The failure does not happen at market — it happens in the research room, where the methodology cannot detect the difference between genuine desire and socially acceptable approval.
Every FMCG research team has experienced the same failure mode: a concept tests brilliantly. Focus group participants call it interesting, novel, distinctive. Quantitative scores are strong. The brand team greenlights. The product launches. Sales disappoint.
The failure does not happen at market — it happens in the focus group room, the moderated discussion, the post-session recall survey. When participants say a concept is "interesting," they are producing the safest social response available. Interesting is positive, inoffensive, and non-committal. It is also not a purchase signal.
The genuine emotional response — the one that actually predicts whether someone reaches for a product on a shelf — is involuntary, pre-verbal, and occurs within 200 milliseconds of first exposure. No focus group moderator, survey question, or post-session recall exercise can capture it. FACS analysis can.
EchoDepth measures VAD (Valence, Arousal, Dominance) continuously from the moment stimulus exposure begins. The result is a emotional response profile for every concept, every participant, every second of exposure — before any social moderation has occurred.
Traditional research — what you get
Social desirability bias — consumers describe concepts as interesting because it is the safest group response
The articulation gap — first-exposure emotional reactions cannot be accurately described in words
Concept contamination — carryover between concepts in sequential tests distorts individual responses
Group dynamics — dominant voices shift group opinion; minority responses are suppressed
End-of-session rating — you get a number at the end, not the signal throughout
EchoDepth — what you get instead
Involuntary signal — facial Action Units cannot be consciously controlled; they reveal genuine response
First-exposure capture — emotional data recorded at the moment of exposure, not recalled afterwards
Individual, not group — every participant analysed independently; no peer contamination
Desire vs curiosity distinguished — VAD scoring separates genuine purchase signal from polite interest
Moment-to-moment timeline — see exactly when and where emotional response peaks or drops
Applications
Every stage of the FMCG research cycle. Every type of stimulus.
Packaging
Packaging concept and design testing — packaging research software
Test pack concepts against each other and against existing range at first-exposure. EchoDepth identifies which design drives genuine positive affect, which drives neutral curiosity, and which generates suppressed aversion — broken down by target demographic, shelf position, and colour/texture variant. Carryover analysis detects concept contamination in sequential tests.
Brand
Brand identity and repositioning evaluation
Measure the involuntary emotional response to brand expressions — logo evolution, new design language, updated pack architecture — before committing to a repositioning. EchoDepth identifies which brand elements carry positive emotional equity and which generate confusion or indifference that stated preference questions systematically miss.
NPD
New product introduction research
At first exposure to a new product — name, visual, proposition — EchoDepth captures the emotional response before any rationalisation occurs. The result is the only reliable signal of genuine concept resonance: the pre-verbal feeling that determines whether someone reaches for a product or walks past it. Target audience segmentation shows which demographic the concept genuinely lands with.
Advertising
Advertising and creative pre-testing
Second-by-second emotional curves across video creative — showing exactly which moment lands, which triggers concern, and where attention drops — before the campaign goes live. Post-campaign emotional shift measurement shows whether the campaign has genuinely moved brand emotional response or merely increased recognition. Audio, voiceover, and music are analysed independently to identify the driver.
Retail
Shelf presence and retail environment
Simulated shelf configurations delivered remotely. EchoDepth measures attention direction, emotional response to individual SKUs or brand bays, and the emotional state at the moment of simulated decision. Captures the genuine in-store physiological response that determines purchase behaviour, without facility cost or geographic constraint.
Price
Price point emotional response
Price sensitivity research using direct questioning produces systematically biased results — consumers always report more sensitivity than they express behaviourally. EchoDepth captures the involuntary valence and dominance response at the moment of price exposure, distinguishing genuine reluctance from automatic social negotiation. The result is a realistic price elasticity signal, not a stated preference distortion.
In practice
What EchoDepth reveals that traditional FMCG research cannot.
Scenario: three-pack concept test
Three packaging concepts tested sequentially with 40 participants. Stated preference at end of session: Concept C wins (voted "most interesting" by 52%). Self-report scores are similar across all three.
EchoDepth VAD output at first exposure:
Insight: Concept A generates the highest genuine positive valence at first exposure. Concept C was voted "most interesting" — but "interesting" and "desire" are different emotional states. Concept A launches. Concept C becomes a future variant.
Scenario: advertising pre-test
A 30-second TV ad tested with 60 target consumers before broadcast. End-of-session recall scores are positive. Brand tracking shows 71% recall intent. Standard pre-test: pass.
Seconds 0–8 (brand opening): V 0.71, A 0.62 — engaged, positive
Seconds 9–16 (price reveal): V drops 0.71 → 0.38. AU4 brow tension. Arousal spike.
Seconds 17–24 (product hero): V recovers to 0.55. Dominance low (0.31).
Seconds 25–30 (brand close): V 0.61. Dominance still below baseline.
Insight: Price reveal triggers suppressed negative response that self-report masked. The ad recovers emotionally but dominance (sense of control and confidence) does not fully return. Recommendation: reorder to reveal price after the product hero. Recut tested — dominance holds through to brand close.
Scenario: segment divergence in brand repositioning
A heritage FMCG brand tests a modernised visual identity with two segments: loyal existing buyers (35–54) and target new buyers (22–34). Group sessions report that both groups like the new design.
Existing buyers (35–54): V 0.42, A 0.71 — high arousal, moderate valence. Nostalgia disruption signal.
Target new buyers (22–34): V 0.74, A 0.58, D 0.69 — strong positive, confident. Genuine desire signal.
Insight: The new design wins the target segment decisively. But existing buyers — who said they liked it — show a disruption response that predicts brand switching risk. Recommendation: phased rollout with transitional pack architecture retaining two heritage cues. Loyalty protected without sacrificing new buyer appeal.
Scenario: NPD concept elimination
Five NPD concepts tested. All five score between 6.2 and 7.1 on standard appeal questions. The research team cannot differentiate on stated preference alone. The brand team needs to take two concepts to the next stage.
EchoDepth first-exposure emotional ranking (genuine desire signal):
1st — Concept D: V 0.81, D 0.74
2nd — Concept A: V 0.71, D 0.68
3rd — Concept C: V 0.63, D 0.51
4th — Concept E: V 0.58, D 0.44
5th — Concept B: V 0.41, D 0.28 (concealed indifference)
Insight: Stated preference gives a 0.9-point range across five concepts. EchoDepth gives a 0.4-point valence range and a 0.46-point dominance range. Concepts D and A go to the next stage. Concept B — which scored 6.5 on stated appeal — is eliminated on the basis of a concealed indifference signal that no standard metric would have detected.
