What happens when consumers start trusting AI agents more than friends for shopping advice? On this episode of Retailgentic, we welcome Professor Luca Cian from the University of Virginia’s Darden School of Business.

Luca brings a unique perspective as a psychologist turned marketing scholar whose research spans visual persuasion, AI adoption, and consumer trust. We dive deep into how shoppers perceive AI in utilitarian vs. hedonic purchases, why trust in AI depends on “augmented decision-making,” and how brands should prepare for an AI-first retail future.

From the paradox of choice to the emerging world of “GenAI Engine Optimization (GEO),” this conversation is packed with insights on how AI is rewriting the rules of marketing, loyalty, and consumer psychology.

Tune in for:

• The psychology of trust in AI: why we accept AI for practical tasks but resist it in creative/hedonic domains
• The paradox of choice and how AI alleviates decision fatigue
• How brands can adapt to the rise of agentic commerce and GEO (GenAI Engine Optimization)
• Future of loyalty programs when shopping decisions are mediated by AI agents
