Do bigger language models guarantee higher research accuracy?

Not necessarily. Larger language models (with more parameters and training data) often produce more fluent and knowledgeable-sounding outputs, but that doesn't automatically equate to greater accuracy on research tasks. In fact, big models can still "hallucinate" facts or confidently give wrong answers if the information isn't in their training data. What matters more is how relevant and up-to-date the model's knowledge is and whether it's augmented with real data. A well-tuned smaller model that's fed curated research information (or used with a live database search) can outperform a huge model working off of generic training alone. Also, bigger models can sometimes be too generalized, missing niche details that a domain-specific tool would catch. In short, while size brings potential, you still need to verify and fact-check AI outputs — treat any model's answer as a starting point that benefits from human validation and subject matter context.

When should AI agents pre-screen concepts before human validation?

Use AI (Artificial Intelligence) agents to pre-screen concepts when you face a high volume of ideas or submissions that would overwhelm human reviewers in early stages. If you have hundreds of product concepts from an innovation challenge or lots of creative content generated (for instance, by an AI itself), an AI agent can quickly filter or score them based on predefined criteria or learned patterns of what a successful concept looks like. This approach is especially useful at the start of an innovation funnel or concept testing process, where you want to eliminate the clear non-starters and focus human attention on the top candidates. In short, deploy AI for the first pass to save time when scale is an issue, but always follow with human validation to catch nuances or creative potential that an algorithm might miss.

Which disclosures satisfy ethics boards for synthetic participants?

To satisfy ethics boards when using synthetic participants, researchers should fully disclose how these AI-generated or simulated individuals are used, why they're used, and assure reviewers that no real humans are being deceived or harmed. In study documents and consent forms, clearly state that some participants or data are synthetic (computer-generated) and describe their source (e.g., derived from a model trained on historical data). Explain the rationale for including synthetics--perhaps to model rare scenarios or boost sample size--and detail how it benefits the research. It's also important to clarify privacy safeguards: if synthetic data is based on real records, confirm that it's sufficiently anonymized to protect identities. By being transparent and showing that synthetic participants enhance the study without ethical downsides, you address key concerns around informed consent, risk to real people, and the scientific validity of your approach.

How should we combine session replay with moderated follow-ups ethically?

To combine session replay with moderated follow-ups ethically, you need to be transparent and respect user consent - essentially, record user sessions only with permission and approach any follow-up in a privacy-conscious, voluntary manner. For example, let users know (via a notice or consent banner) that their on-site actions might be recorded for research or improvement, and give them an opt-out. Then, if session replay reveals something noteworthy (maybe a user struggled at checkout), you shouldn't directly contact them referencing their exact behavior without context. Instead, reach out in a respectful way - perhaps an email or pop-up asking if they'd be willing to discuss their experience, without saying "we saw you do X," until they agree to participate. Throughout this process, keep personal data protected (mask or anonymize details in replays) and limit who can view the recordings. The guiding principle is to ensure users feel in control and not spied on: they should be informed about recordings and willingly opt into any follow-up discussion about their session.

Does synthetic data remove bias and can it amplify historical bias?

Synthetic data can help reduce bias in some cases, but it does not automatically remove bias - in fact, if generated carelessly, it can even amplify historical biases. For example, if an AI model creates synthetic records based on a skewed dataset, those data points will mirror or exaggerate the original bias rather than correct it, potentially creating a feedback loop that compounds unfair patterns. Synthetic datasets are often used to balance underrepresented groups or to avoid exposing real personal data, but their ability to improve fairness depends on careful design and validation. Without deliberate bias mitigation steps - such as rebalancing data distributions or checking model outputs for bias - synthetic data may inadvertently reinforce the very disparities one hopes to eliminate.

What is EyeSee?

The best decisions start with a better understanding of how people behave.

What makes EyeSee different is that we don't just ask people what they think. We observe what they do. We combine behavioral tools like Eye Tracking, Emotion Recognition and Virtual Shopping with supporting consumer feedback, giving us both the what and the why.

Our multidisciplinary experts then turn those observations into clear, actionable recommendations that help brands grow. We apply this across the full innovation cycle, in three areas: Pack, Shopper, and Ad.

In Pack, we developed a unique design testing protocol that spans from screening to full pack evaluation. It supports both light brand renovation and high-stake NPD.

That experience also powers our predictive packaging screening solution. Built on insights from 10,000+ pack designs and 15 million behavioral data points, PackSee.AI predicts which designs will win, and fast. By collaborating closely with our partners and listening to their needs, we soon developed PackSee.AI Context, a new way to understand how pack performs where it matters most: on shelf.

In Shopper, we've developed EyeStore: highly realistic, interactive 3D replicas of real retail environments. It lets us observe how consumers browse, shop and make decisions in context, to test changes before they reach the shelf. Similarly, in E-commerce, we recreate interactive online shops to optimize how products are found, viewed and chosen online.

For Advertising research, Creative Intelligence is our testing suite. It places ads in realistic social media environments to show which creatives grab attention, trigger emotion, and get remembered.

Today, brands in more than 50 countries trust EyeSee.

Because understanding behavior is not something we added along the way. It's the foundation EyeSee was built on.
