Do People Around the World React to Advertising in the Same Way? This Study Investigates

  • JOURNAL OF ADVERTISING RESEARCH

Can facial expressions reliably reveal emotional responses to advertising across cultures? A new study published in the Journal of Advertising Research suggests the answer is yes. Drawing on a massive global database of more than 70,000 advertising studies and nearly 3.8 million frames of viewer facial responses, the authors found remarkably consistent facial expression patterns across 12 world regions. The study provides evidence that certain expressions linked to happiness, disgust, surprise and awe appear universally in response to advertising and entertainment content—supporting the use of automated facial coding as a valuable tool in global advertising research and creative testing.

Finding Your Brand’s AI Niche: How Prompt Nuance Shapes Product Recommendations

  • Psychology of Gen AI
  • ARF; MSI

As generative AI becomes a key part of how consumers discover and evaluate products, a new question emerges for marketers: how can they ensure their brands show up in AI-driven recommendations? This ARF and MSI experiment, the second phase of the seventh study in the Psychology of Gen AI series, reveals that even small changes in prompt wording can significantly influence which brands appear—helping non-market dominant brands carve out visibility by aligning with specific product attributes rather than competing broadly for “best” status.

Better Creative, Fewer Tests: A New Framework for Efficient Self-Improving Systems

  • ARF; MSI

This MSI working paper introduces TextBO, a novel AI framework designed to improve marketing decisions more efficiently by minimizing costly evaluation cycles. By combining large language models with Bayesian optimization principles, the approach enables AI systems to iteratively refine outputs—such as ad creatives—while requiring fewer real-world tests. The result: faster learning, better-performing outcomes, and a more scalable path to AI-driven decision-making.
