Cannes Lions 2026 jurors kept saying the same thing in early July: the industry solved reach and lost the plot. AI, production speed, distribution — all of it was on the table, and the Lions still went to work built on a real observation about how people actually behave, not to whoever used the most technology. That's not a taste problem, it's a measurable blind spot. PwC's Trust in Business tracking has been putting a number on it for years: 90% of executives believe customers hold their company in high trust, only 30% of consumers agree. The gap is now 60 points, wider than the 57 points recorded in both 2022 and 2023. The industry got better at reach. It didn't get better at trust.

Why your executive team defends a trust number that isn't real

Because strategy gets built from the inside out, and internally generated metrics are structurally biased upward. The team that writes the brand health survey is also accountable for its result; the executive interpreting the NPS score is also the one tasked with raising it. Behavioral science has a name for the reflex: self-serving bias, the tendency to credit good outcomes to our own judgment and blame bad ones on the market. The organizational version is quieter and more expensive — companies value a framework roughly 63% more when they built it themselves, purely because they built it, the same mechanism behind the IKEA effect. So when a leadership team looks at a rising trust chart in a quarterly review, what they're often reading back is their own narrative, not the customer's actual state of mind. The instrument isn't broken. The person holding it is grading their own test.

The gap isn't closing, it's compounding

Because younger consumers now extend trust to evidence, not habit, and they've stopped giving brands the benefit of the doubt that kept the gap invisible. 59% of consumers generally stick with familiar brands; among Gen Z that drops to 46%. 42% say they've actually quit a brand over a values mismatch, and 67% tie loyalty directly to whether a brand speaks openly rather than performs. That tracks with what Cannes jurors flagged: the strongest work this year didn't interrupt people, it gave them something to participate in — entries from brands like Heineken and KitKat turned an audience into a cast rather than a crowd. Gen Z is asking for the same shift at the relationship level: treat me as a verifiable counterpart, not a target segment. So while a leadership dashboard shows trust holding steady, the fastest-moving cohort underneath it is already learning to leave faster and with less guilt. Both readings are real. They're just measuring different customers.

What a 60-point miscalibration costs in the media plan

Because the same overconfidence shows up on the spend side, and it lands directly on the media line. IAB forecasts global ad spend growing 9.5–9.8% in 2026; in the same research, 42% of marketers privately expect their own budgets to shrink, up from 22% a year earlier. That's a second trust gap, running between what the industry says publicly and what buyers believe in the room. The creator economy shows the identical pattern at a different scale: spend is tracking toward $44 billion, yet two-thirds of brands still can't say whether their influencer budget actually worked. Capital is already repricing that uncertainty on its own — performance-based creator deals have jumped from 23% of arrangements two years ago to more than half today, and micro-creators now command close to half of U.S. influencer spend, up from under 20% in 2021. That's not a trend piece. It's the market quietly refusing to trust its own reach numbers as much as the org chart still does.

A brand doesn't actually lose trust the day a customer notices the gap. It loses trust the day it stops measuring for one.

What this means for your next quarter

Start by asking who owns your brand health score — if the same team writes the question and grades the answer, that number is a defense, not a diagnosis. Second, run every brief through the question Cannes jurors kept asking out loud: is this reach, or is this insight? Third, break out Gen Z as its own trust line; a rising blended average can hide the exact cohort leaving fastest. Finally, move a real slice of creator budget to performance-based deals, not because it's fashionable but because it's the one number in the plan nobody on your team can quietly inflate. Sixty points isn't an abstract statistic. It's an early read on which customers are already, quietly, on their way out.
