If advertising is created to sell a product, service or even an idea, it's helpful if the message is not only clear but also believable to the intended audience. According to a new Adweek Media/Harris Poll of 2,098 U.S. adults surveyed online in October, only one in five American adults say they trust that advertising is honest in its claims all or most of the time. Rather, a majority say they trust that advertising is sometimes honest in its claims, and just over one in ten say that they never trust that advertising is honest in its claims. Although all adults seem somewhat unsure about the believability of advertising claims, older adults are more suspicious than younger adults. While 90% of young adults aged 18-34 say they trust that advertising is honest in its claims at least sometimes, 86% of older adults agree. Of those, 35-44 say this, as do 84% of those 45-54, and 81% of those 55 years and older. Conversely, almost one in five adults 55 and older say that they never trust that advertising is honest, compared to less than one in ten 18-34 year olds who say the same.

However, half of Americans say they trust neither. Just as younger adults showed less skepticism about advertising honesty, younger adults also show more confidence in the various regulatory checks and systems. Adults aged 18-34 are more likely than those 55 and older to say both that they trust government regulation (33% vs. 26%) and advertising self-regulation (26% vs. 18%) to ensure that advertising is honest. 56% of older Americans, 55 and older, say that they trust neither the industry nor the institution to regulate advertising honesty, compared to 44% of those 35-44 and 41% of 18-34 year olds. Americans with higher education say they trust the government to regulate advertising much more than those with less formal educations do. Almost two in five who have graduated college say that they trust government regulation, compared to 29% who have attended, but not graduated, from college, and 22% who have not attended any college.

However, the fact that younger Americans are less skeptical than older Americans may be a positive. It's possible that both the honesty of ad claims and the regulation of the industry are improving, yet older Americans may still be cautious, especially if they have memories from previous negative experiences.
