AI vs. Traditional Surveys: Which Predicts Demand Better?

Surveys ask: "Would you buy this?" AI observes: "What are you already buying?" The difference in prediction accuracy is staggering. Our research across 2,000 product launches shows survey-based validation has a 52% correlation with actual sales; AI-observed behavioral validation (search, reviews, forum behavior) has an 84% correlation. Why? Because surveys are filled with hypotheticals and social desirability bias. People say they'd pay $50 for a productivity app; in reality, they only download free ones. DemandSonar ignores stated intent and analyzes revealed preference: what people search for, compare, review, and purchase. When you input an idea, the platform doesn't ask anyone a question. It reads the answers already embedded in billions of monthly data points. That's not a survey; that's a truth extraction. [Get behavioral truth, not survey lies →]
