This new AI technique creates ‘digital twin’ consumers, and it could kill the traditional survey industry
A new paper details a revolutionary method allowing LLMs to accurately simulate human consumer behavior, poised to reshape market research. This technique creates synthetic consumers providing realistic product ratings and detailed reasoning. Existing AI market research struggles with LLMs producing unrealistic numerical ratings. The Semantic Similarity Rating (SSR) method prompts LLMs for textual opinions, converting them into numerical vectors. SSR's model achieved near-human accuracy when tested with a real-world dataset, mirroring human rating distributions. This development arrives as traditional survey integrity wanes due to AI-generated responses. This research offers a controlled way to generate high-fidelity synthetic data, shifting from data defense to offense. The method's success relies on quality text embeddings, accurately capturing purchase intent. This moves from analyzing existing data to generating novel insights before product launches. Digital twins of consumer segments can test product concepts offering rapid innovation cycles.

How can an imitative model like an LLM outperform the experts it is trained on? Our new COLM paper outlines three types of transcendence and shows that each one relies on a different aspect of data diversity. arxiv.org/abs/2508.17669

a trivia fact about this paper is that we submitted it to arxiv weeks ago, and it was hanging there in limbo for quite a while. apparently because we submitted to "AI" while they moved it to "HCI".
When reading AI reasoning text (aka CoT), we (humans) form a narrative about the underlying computation process, which we take as a transparent explanation of model behavior. But what if our narratives are wrong? We measure that and find it usually is.

Now on arXiv: arxiv.org/abs/2508.16599

A new generation of AI models generates step-by-step reasoning text before producing an answer. This text appears to offer a human-readable window into their computation process, and is increasingly r...

Open models have made a pretty comprehensive shift in the last few years from an afterthought and debate point over AI safety to an industry norm

We’ll increase the pace of our coverage so long as the pace of releases stays this high

Doubt we’ll see definitive proof - RCTs would be unethical in humans - but animal studies have provided that.
