  • ARF; MSI

Generative search may help consumers move from broadly stated needs to more focused shopping decisions. In a field experiment involving more than 6.4 million users of Meituan—a Chinese e-commerce platform, consumers given AI-generated responses placed more orders and generated greater transaction value than those using a conventional keyword search. They also spent less time browsing and concentrated their attention on fewer, more relevant categories and merchants.

Based on a survey of 500 adults who use AI at least weekly and have used it for shopping or product research, the latest report in the ARF and MSI Psych of Gen AI series examines how much of the decision process consumers are willing to delegate, where they still insist on control and what their growing reliance on AI means for marketers.

Big vs. Small Influencers: Matching Follower Size to Message Strategy

  • ARF
  • JOURNAL OF ADVERTISING RESEARCH

Should brands partner with influencers who have massive followings—or smaller, more niche audiences? New research shows that the answer depends on how the message is delivered. Using construal level theory, the study finds that follower size signals psychological “social distance,” which shapes how consumers process influencer content. Smaller influencers are most persuasive when brand information is explicit and shared on their own channels, while mega-influencers perform better when branding is subtle or when content appears on brand-owned channels. The results suggest that aligning influencer follower size with message diagnosticity can significantly improve campaign effectiveness.

  • JOURNAL OF ADVERTISING RESEARCH

Can arrogance work in advertising? New research shows that visually arrogant expressions—such as confident, unsmiling, upward-tilted faces—can significantly increase consumer attention and brand recall. But attention alone doesn’t guarantee sales. Whether arrogance helps or hurts purchase intention depends on how well it aligns with a brand’s positioning. When arrogance reinforces a brand’s sense of leadership or distinctiveness, it can drive stronger buying intent. When it doesn’t, it can backfire.

Why Personalization Persuades: What the Evidence Really Says

  • ARF
  • JOURNAL OF ADVERTISING RESEARCH

Does personalized advertising really work—or does it risk turning consumers off? A large-scale meta-analysis of 53 experimental studies finds that personalized ads are, on average, more persuasive than non-personalized ones, improving consumer attitudes and behavioral intentions. Crucially, personalization works not because it feels intrusive, but because it increases perceived relevance. When consumers see ads that connect to their interests and identities, persuasion improves—making personalization a low-risk, high-reward strategy when done well.
