Generative AI is becoming an active participant in the purchase journey, helping consumers compare products, interpret information and select among alternatives. 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.

As consumers add AI-powered search engines to their information routines, their behavior changes with the platform and purpose of the search. An observational study of 848 real-world searches found that traditional search still dominated while AI-powered search was used more often for advice-seeking, drew substantially longer queries and produced fewer outbound clicks. The findings suggest that advertisers may need to rethink long-tail keyword strategies, website optimization and ad models as search behavior becomes divided across traditional and generative platforms.

After conducting eight studies over the past year, what has the ARF learned about the psychology of generative AI? Across experiments examining bias, identity cues, product recommendations, executive decision-making and AI-assisted research, four patterns repeatedly emerged: GenAI tends to compress human variability into dominant responses, subtle differences in prompting can meaningfully change outputs, different models bring their own constraints and tendencies and AI can imitate the language of expertise more readily than it can exercise expert judgment. Taken together, the studies suggest that GenAI’s greatest strength and its greatest risk may be the same: its ability to produce coherent, convincing answers can make compression, instability and missing judgment difficult to see.

Artificial intelligence has rapidly become part of the everyday marketing toolkit, transforming everything from creative development and campaign measurement to analytics and customer engagement. Drawing on two nationwide surveys of more than 200 U.S. advertisers and agencies, this new ARF study explores where AI adoption stands today, which tools marketers rely on most, how organizations are validating AI outputs and the governance practices emerging as AI becomes central to marketing operations.
