Concern Is Rising

Three independent studies tracking different questions all show negative sentiment toward AI in advertising increasing year over year. The specific percentages measure different things, but the direction is the same.

The Perception Gap

Ad industry executives overestimate how positively consumers feel about AI. The gap grew from 32 to 37 points between 2024 and 2026.

Distrust Across Studies

These results come from separate research organizations using different methodologies. The skepticism shows up regardless of who asks the question.

Who's Most Skeptical?

Gen Z reports more negative sentiment toward AI ads than Millennials, despite being the generation most likely to use AI tools daily.

Key Findings

75% of radio listeners oppose AI cloned voices replacing live talent

Among 29,000+ core radio listeners surveyed across 500+ stations

Jacobs Media (2024)

39% have "big issues" with AI voicing radio commercials

Resistance extends beyond voice cloning to AI-voiced ads specifically

Top perceived threat: manipulation and deception (69%)

Podcastle (now Async) (2024)

2 in 3 people incorrectly identified a human voice as AI-generated

Respondents were so primed to expect AI that they misidentified real human voices. The distrust affects perception in both directions.

Only 29% of marketers think AI ads bother consumers — a 12-point perception gap

41% express distrust. Usage is high but confidence in AI output remains low.

YouGov (2025)

49% of Americans reject the growing use of AI — only 17% embrace it

A 3:1 ratio of rejection to embrace. The widest gap among the five developed nations surveyed.

Edelman (2025)

36% less likely to buy from brands using AI in ads

Up from 32% in December 2024. A 4-point increase in under a year.

CivicScience (2025)

A 37-point perception gap that widened from 32 points in 2024

IAB (2026)

From a survey of 2,002 US consumers. Near-universal demand for AI transparency.

The generation most familiar with AI is also concerned about its effect on creativity.

Pew Research (2025)

The Other Side of the Data

Not all the data points in the same direction. These findings add context to the overall picture.

Personalized AI ads were 22 percentage points more effective at increasing brand favorability than generic ads

In an Intel Evo campaign study, personalization drove the lift. Respondents may not have known the ads were AI-generated.

Veritonic/Instreamatic (2024)Note: Study commissioned by Instreamatic, an AI audio ad platform

48% of consumers trust ads co-created by a person with AI support

Compared to 13% for fully AI-created ads. Human involvement appears to be the deciding trust factor.

A growing minority see creative potential in AI-assisted advertising.
