Most brands can point to a values statement. Far fewer can prove consumers believe it.

Bigeye's newest intelligence briefing, The Believability Gap, starts with a single comparison: 83% of marketers believe the brands they represent are living their stated purpose. Only 43% of consumers agree. That 40-point gap isn't a communications problem to be worded around. It's a proof problem, and it sits squarely on the commercial side of the business.

This briefing draws on Edelman's 2026 Trust Barometer, Razorfish and Vice Media Group's 2026 purpose study, McKinsey, NielsenIQ, Morning Consult, and original In Clear Focus interviews with Paul Ingram (Columbia Business School), Visha Kudhail (author, Authentic Marketing), and Sandy Skees (author, Purposeful Brands), to answer a narrower and more useful question than "do consumers care about values": what do they mean when they say it, what do they ask brands to actually do about it, what do they do at the shelf, and where does a brand's claim get believed.

Why This Research Matters

Trust has quietly moved from a soft, reputational metric to a hard condition of purchase. Edelman's 2026 study of 17,688 people across 15 nations found trust (88%), quality (89%), and value (88%) now sit within a single point of each other. Trust is no longer the variable brands can under-invest in relative to price and quality.

At the same time, 62% of US consumers say they weigh a brand's values when they buy, but only 43% believe brands are actually living the purpose they claim. Marketers, asked the same question about their own brands, answered 83% in the affirmative. That distance between internal confidence and external belief is where this briefing is aimed.

Key Findings at a Glance

• 83% of marketers believe their brand is living its stated purpose, versus 43% of consumers who agree (Razorfish/Vice Media Group, February 2026).

• 62% of US consumers say they weigh a brand's values when they buy.

• 88% for trust, 89% for quality, and 88% for value: Edelman's 2026 Trust Barometer puts all three within a single point of each other.

• 64% of consumers now choose brands based on their beliefs (Edelman).

• 13% of US consumers would pay significantly more for sustainable packaging (McKinsey, 2025).

• 41% cite unpaid voices (friends, family, and people like them) as the biggest influence on brand trust, against 20% who point to what the brand says about itself.

• 37% of consumers who follow content creators tried a brand for the first time because of a creator in the past six months.

• 23.8% to 10.2%: the fall in positive conversation about Coca-Cola after its 2025 AI-produced holiday campaign launched (CARMA).

What's Inside the Briefing

What a Value Actually Is

The briefing opens with Columbia Business School professor Paul Ingram's definition: a value is a principle of evaluation, the standard people use to judge everything from a person to a product to a brand. It covers why most people can name only one or two of their own values at a time, why the exact word a person uses to describe a value does measurable physical work (embodied cognition, including a drop in measured cortisol), and why brands should identify a single "chief value," the one feeling the brand should produce, rather than trying to own a long list of adjectives.

For a deeper conversation, listen to Paul Ingram, whose work explores how values shape the decisions people and organizations make, on Bigeye's In Clear Focus podcast. The episode, "What Do You Really Stand For?", covers what values actually are, how they influence behavior, and what they mean for brands trying to build genuine trust with consumers.

What Consumers Ask Brands to Do

This section covers the behavior consumers actually reward: consistency measured in years, not a single campaign. It includes Edelman's finding that 64% of consumers now choose brands based on their beliefs, Visha Kudhail's framework for authenticity as an always-on operating model, and Sandy Skees's ally/advocate/activist framework for calibrating how far a brand goes on a given issue. It also walks through three real 2025-2026 cases, Costco, e.l.f. Beauty, and Target, comparing what happened commercially to brands that held a position versus one that reversed it.

What Consumers Do at the Shelf

Here the briefing draws a sharp line between what earns a brand consideration and what earns it a premium. McKinsey's 2025 research across 11 countries places price and quality as the dominant purchase drivers, with environmental impact ranking below both. It also unpacks a Gen Z paradox: the generation most likely to say it would pay more for sustainability is also the generation most likely to call grocery brands poor value for the price.

Where a Claim Gets Believed

The final section covers who actually gets believed when a brand makes a claim. Edelman's data shows unpaid voices, friends, family, and people like the consumer, carry more than double the trust weight of what a brand says about itself. It also covers Paul Ingram's research on how a brand's internal culture leaks into what it can credibly claim externally, and closes with a look at AI-generated content, including a real case study of audience reaction to Coca-Cola's AI-produced holiday campaign.

Key Themes

The 40-Point Gap

The briefing's headline finding: 83% of marketers believe their brand is living its stated purpose, versus 43% of consumers who agree (Razorfish/Vice Media Group, February 2026). That 40-point gap is framed throughout the briefing not as a messaging failure but as a proof failure, one that gets closed with evidence, not better copy.

Trust Now Rivals Price and Quality

Edelman's 2026 Trust Barometer found trust (88%), quality (89%), and value (88%) sitting within a single point of each other across 17,688 respondents in 15 nations. Trust has moved from a differentiator to a baseline condition of purchase, on par with the two factors marketers have always budgeted for.

Consideration, Not a Premium

Values earn a brand a place on the shortlist. In the US, they don't reliably earn it a higher price. McKinsey's 2025 research found only 13% of US consumers would pay significantly more for sustainable packaging, and US willingness to pay a sustainability premium runs behind China, India, Brazil, and Mexico. The briefing's guidance: price the values position as a route to consideration and loyalty, not to margin.

Unpaid Voices Carry the Proof

Edelman's 2026 data found unpaid voices, meaning friends, family, and people like the consumer, are cited as the biggest influence on brand trust by 41% of respondents, against 20% who point to what the brand says about itself. 62% of consumers follow content creators, and among that group, 37% tried a brand for the first time because of a creator in the past six months.

Polish Is No Longer Proof

Generative AI has raised, not lowered, the value of visible authenticity. Attest's 2025 study found roughly 46% of people uncomfortable with AI in advertising, and the briefing includes a real case: CARMA measured positive conversation about Coca-Cola fall from 23.8% to 10.2% after its 2025 AI-produced holiday campaign launched, even as negative conversation held roughly flat.

Who This Research Is For

This briefing is built for marketers who already treat brand purpose as a strategic asset and need a current, evidence-based read on whether consumers actually believe the claim.

It's most directly relevant to:

• Brand and consumer marketers deciding how much budget to shift from asserting values to producing evidence of them

• CMOs and brand leaders weighing whether to take, hold, or walk back a public position on an issue

• Agency strategists and brand planners who need a credible, current data foundation for positioning work, briefs, or new business

• Creative and content teams deciding how much AI-generated content a values-forward brand can use without a trust cost

How to Use This Research

• Pressure-test your purpose claims against the 40-point gap between what marketers and consumers believe

• Move budget from asserting values to proving them, with evidence consumers can see

• Plan for unpaid voices, since friends, family, and people like your customers carry more than double the trust weight of what a brand says about itself

• Set limits on AI-generated content for values-forward brands, using the Coca-Cola case as a reference point

About the Research

Data in the briefing is drawn from an 18-month window ending July 2026, US-focused, including the Edelman Trust Barometer 2026, Edelman's 2025 Brand Trust report, Razorfish/Vice Media Group, McKinsey, NielsenIQ, Morning Consult, CARMA, Attest, IAB/Sonata Insights, and original In Clear Focus interviews with Paul Ingram, Visha Kudhail, and Sandy Skees.
