The Face of AI Endorsement — Human vs. Cartoon Avatars

Do consumers respond differently to AI avatars that look human versus those that look cartoon-like? In this episode, June-Ho Chung (Inha University) and Sungjun “Steven” Park (Queen Mary University of London; National Chengchi University) join me to discuss their Journal of Advertising Research article, Designing AI Agents for New Product Endorsement: Do Human-Like or Cartoon-Like AI-Generated Endorsers Evoke More Positive Ad Engagement from Consumers? The article is co-authored with Yiting (Tami) Chu (National Chengchi University). We talk about why human-like AI avatars tend to generate stronger engagement and positive emotions, especially when promoting new or unfamiliar products. June-Ho and Steven walk through controlled experiments that compare human-like and cartoon-style endorsers across preference, emotions, and ad engagement. We discuss why familiarity with faces can shape reactions and when a simpler, cartoon style may still fit the brief. Finally, we translate the findings into practical guidance for creative teams choosing avatar style for new product ads.Read the full paper here:https://www.tandfonline.com/doi/full/10.1080/00218499.2025.2497615To keep up to date on the latest JAR news sign up for our newsletter: https://lp.constantcontactpages.com/su/mtD04QNAnd follow us on LinkedIn: https://www.linkedin.com/company/82528291/admin/
