bias correction in market research

Bias in market research isn’t always easy to spot—until a product underperforms, a campaign flops, or a customer segment feels left out. In this article, we share a real-world-inspired use case that illustrates how synthetic data—specifically through Correlix—can help correct sample bias and ensure fairer, more accurate outcomes.

The Challenge: A Product Tested with the Wrong Mix of Respondents

A major consumer packaged goods (CPG) brand approached us after receiving mixed feedback on a new plant-based snack line they had tested in three European markets. The initial concept test, fielded through a traditional online panel provider, had suggested strong appeal among health-conscious Millennials. Based on those results, the brand moved forward with a launch in key retail locations.

But the early in-market feedback told a different story. Sales were underwhelming, and consumer complaints pointed to a disconnect in taste and packaging expectations—particularly among older and rural consumers.

Upon reviewing the research inputs, it became clear that the original sample was heavily skewed toward urban, digitally active, health-focused respondents. The project had unintentionally excluded a large portion of the target market—particularly Gen X and Baby Boomers in rural or suburban settings.

The Objective: Correct the Sampling Bias and Test Adjusted Concepts

The client needed to understand:

  • What insights were missed due to skewed sampling
  • How the concept might resonate across underrepresented segments
  • Whether reformulation or repositioning could expand the product’s appeal

Rather than re-field the entire study (costly and time-consuming), they turned to Correlix, our synthetic data and bias correction solution.

The Solution: Using Correlix for Bias Correction and Scenario Testing

Step 1: Diagnose the Bias

We ingested the original dataset and ran a bias analysis comparing the respondent profile to real-world demographic distributions from the brand’s target markets. The findings confirmed underrepresentation of key segments, particularly:

  • Age 50–70
  • Residents of Tier 2 and 3 towns
  • Lower income brackets
  • Less health-conscious dietary habits

Step 2: Generate Balanced Synthetic Data

Using Correlix, we created a synthetic extension of the dataset to fill those gaps. We modeled responses from underrepresented groups based on:

  • Existing panel data from DataDiggers’ proprietary profiling system
  • Relevant behavioral, lifestyle, and attitudinal patterns
  • Advanced ML models ensuring statistical integrity and realism

These synthetic respondents were not “invented from scratch,” but derived from pattern-based logic grounded in real-world data.

Step 3: Re-Test the Product Concept

We ran simulations using the corrected dataset to test:

  • Original concept appeal across a balanced population
  • A “repositioned” variant emphasizing affordability and traditional flavor cues
  • Packaging design tweaks for improved shelf visibility in smaller retail formats

Step 4: Deliver Insights to Drive Change

The results were eye-opening:

  • The original concept scored lower among the older cohort due to unclear health claims and unfamiliar flavor profiles
  • A reformulated version with more familiar ingredients (e.g., roasted chickpeas instead of exotic seed blends) resonated better
  • Adjusted packaging with clearer messaging and less clutter performed well across all groups

The brand was able to course-correct the positioning and roll out a reformulated variant that performed significantly better in follow-up tests.

The Outcome: Better Representation, Better Results

By using Correlix to simulate responses from missing audience segments, the brand avoided costly missteps and salvaged a high-potential product. Key takeaways included:

  • Improved representation across demographic and geographic lines
  • Faster iteration without needing to re-contact thousands of respondents
  • Cost savings compared to re-fielding the entire study
  • Fairer decision-making, resulting in a product better suited to the full market

The project also demonstrated that synthetic data isn’t a replacement for traditional data, but a powerful augmentation layer that enables smarter, more inclusive research.

Final Thought: Sample Bias Doesn’t Have to Break Your Strategy

Every dataset has blind spots—but that doesn’t mean your insights have to. Whether you're working with legacy data, niche audiences, or limited sample sizes, bias correction with Correlix can help you build a more accurate picture of reality.
