In April 2009, two Domino's Pizza employees in Conover, North Carolina, named Kristy Hammonds and Michael Setzer, filmed themselves doing genuinely unspeakable things to a sandwich and uploaded the videos to YouTube. The videos went viral overnight. Domino's stock price collapsed. According to a Zeta Interactive survey, negative sentiment toward the brand jumped 234% in seventy-two hours. In Conover itself, sales dropped roughly 50%. Six hundred workers were laid off.
It was one of the worst PR disasters in fast-food history. And what Domino's CEO J. Patrick Doyle did next is one of the cleanest applied-behavioral-economics case studies of the last twenty years.
He didn't deny. He didn't deflect. He didn't blame the franchisees, the employees, or social media.
He went on TV, in his own commercial, and said: "Our pizza is bad."
That single move — and the year-long "Pizza Turnaround" campaign it kicked off — used a psychological mechanism most marketers have never heard the name of. It's called the Pratfall Effect, and it was discovered by a Harvard social psychologist named Elliot Aronson in 1966.
The Aronson Coffee Spill
Aronson's original experiment was elegant. He recorded a "Quiz Bowl" performance by an actor playing either a brilliant contestant or an average one. In half the recordings, the actor knocked over a cup of coffee at the end. In the other half, they didn't.
The results were strange. The brilliant contestant became more likable after spilling the coffee. The average contestant became less likable.
Aronson named this the Pratfall Effect. The visible mistake of a highly-competent person humanizes them in a way that makes them more likable. The same mistake from a mediocre person just makes them look worse.
The implication for brands is non-obvious. If you're an already-trusted, already-competent brand, owning a mistake publicly can actually increase trust. If you're a low-trust brand, the same move makes things worse.
Domino's had decades of being known as a fast, reliable, innovative pizza company — they basically invented modern pizza delivery in the 1960s because their first store was too small to seat customers. That reservoir of competence was the prerequisite for the Pratfall move to work. Without it, "our pizza is bad" would have just been an admission of permanent inadequacy.
If you've read Robert Cialdini's Influence, you'll recognize this as a hybrid of his Liking and Authority principles. Daniel Kahneman talks about adjacent territory in Thinking, Fast and Slow under the framing of "trust calibration" — once your audience trusts you, occasional admissions of weakness reinforce trust rather than corrode it.
The Two Biases Doyle Said He Was Watching For
Doyle gave a 2016 interview to Harvard Business Review in which he explained that he'd internalized two specific behavioral economics findings during the turnaround.
The first was Omission Bias — the well-documented human tendency to prefer inaction over action even when action would produce better outcomes, because inaction is invisible while bad action is highly visible. Most CEOs in Doyle's position would have done a soft apology, run some discount promotions, and waited for the news cycle to move on. That's the Omission Bias playing out — the perceived cost of doing nothing is low; the perceived cost of dramatic action is high; ergo, do nothing. Doyle decided that in a crisis, inaction was the riskier move.
The second was Loss Aversion — Kahneman and Tversky's 1979 finding that humans weight losses roughly 2x more heavily than equivalent gains. A typical executive team will protect existing brand equity at almost any cost rather than risk a bold move that might make things worse. Doyle's insight was that the loss had already happened — the brand equity was already gone — and behaving as if it still needed protecting would prevent the radical reinvention that was now required.
The willingness to fail publicly is what made the Pratfall work. A brand that can't fail publicly cannot use this mechanism. Most brands can't.
What I Take From This
The Domino's stock chart from 2009 to 2018 is one of the most absurd things in modern equity markets. The stock 10x'd. Brian Krzanich at Intel famously cited it as the best brand turnaround of his lifetime.
Almost none of that compounding return came from improving the pizza. The pizza did improve — they reformulated the crust, sauce, and cheese — but the reformulation alone would not have moved sentiment. What moved sentiment was the credible public admission of past failure, which only works if you've previously been credibly competent.
This is the bit most copycat "brand apology" campaigns get wrong. They try to use the Pratfall mechanism without earning the prerequisite trust. The result reads as performative, customers see through it, and the brand ends up worse off than if it had stayed quiet.
If you're considering whether your brand can pull a Domino's, the diagnostic is simple. Ask: if we admitted, in detail, that our product is currently bad, would customers respond with relief — or with confirmation that they always suspected as much?
If it's relief, you have a Pratfall opportunity. If it's confirmation, you have a much deeper problem.
