Marketing to Machines: How Trust in AI Changes by Category

As generative AI becomes less of a novelty and more of a necessity, brands must recognize that consumer trust in AI is conditional. While consumers increasingly welcome AI into their lives, they don’t trust it blindly, and their willingness to act on its recommendations changes dramatically depending on the category.

To explore this landscape, Horizon Futures’ latest “Marketing To Machines” research surveyed over 1,000 U.S. adults to understand how they use AI, how much they rely on it, and how they validate its guidance. The findings reveal four distinct relationships consumers have with AI, each requiring a different strategy from brands.

A few things you’ll take away:

  • Validation is a Universal Part of the Journey: Regardless of the category, from the complicated to the simple and familiar, a majority of consumers will take the time to validate a recommendation provided by AI. However, the path to gaining confidence in a recommendation will vary by category.
  • The Four Territories of Trust: Consumer relationships with AI fall into four areas how often people use AI in the category, how reliable they believe it is, and the relative stakes associated with the category and subsequent recommendation:
    • Comfort Zone: Familiar, low-consequence categories where people feel comfortable relying on AI.
    • Guided Choice: Categories where AI is used as a discovery and comparison engine to help narrow the field.
    • Trust Frontier: Higher-stakes areas where AI acts as an advisor, helping consumers build knowledge and ask better questions.
    • Human Anchor: The most consequential categories, where AI supports the process, but confidence comes from human experts.
  • The Path to Confidence Varies: How consumers validate AI’s judgment shifts with the stakes. In the Comfort Zone, validation is casual and community-driven (peers, reviews). In Guided Choice its research driven (specifications, editorial coverage). In Trust Frontier it’s more about expertise (experts, specialized sources). In the Human Anchor quadrant, it requires evidence and reassurance from trusted institutions and professionals.
  • Brand Strategy Must Adapt to the Quadrant: Winning with AI requires a category-specific approach. Brands must either become the default, make the cut for the shortlist, arm consumers with evidence, or bridge AI with human support.
