Modern marketing is trapped in a multi-billion-dollar efficiency illusion. In this high-authority interview, renowned effectiveness expert Peter Field breaks down twenty years of IPA Databank insights to expose how the industry’s obsession with short-term performance marketing and low-cost, low-attention platforms is actively destroying brand equity. Field introduces data-backed evidence behind "The Cost of Dull," explains why traditional CPM is a broken metric, and outlines how the future of sustainable brand growth relies entirely on shifting toward attentive reach.

At alpha.one, our data confirms what Peter Field’s research demonstrates: human attention cannot be bought cheaply or forced through automated scale alone. When brands rely on low-attention environments, even optimized creative fails to register in long-term memory. True effectiveness requires a deliberate alignment of predictive attention modeling and high-attention media allocation to bypass the "dullness trap" entirely.

Key Takeaways (TL;DR)

• The Seduction of Performance: Short-term performance marketing creates an illusion of immediate ROI while quietly starving the baseline brand equity required for long-term growth.
• The Threshold of Memory: If an advertisement fails to secure at least two and a half seconds of continuous attention, it fails to build brand memory.
• The CPM Illusion: Traditional Cost Per Mille (CPM) metrics reward cheap, non-attentive social media reach. Shifting to Cost per Attentive Second reverses the media hierarchy, proving that platforms like TV and YouTube offer far superior financial value.
• The AI Double-Edge: While artificial intelligence offers unprecedented capabilities in predicting attention and scoring creative, training it on biased, platform-owned data creates an echo chamber of ineffective, uniform creative output.

What is Advertising Effectiveness in the Attention Economy?

Advertising effectiveness is the measurable impact of a marketing campaign on long-term business growth, defined by its ability to secure attentive reach, generate brand salience, and drive profitability. True effectiveness requires creative execution and media placement to cross the critical 2.5-second human attention threshold necessary to establish permanent brand memories.

The Short-Term Seduction: Why Performance Marketing Alone Fails

‍After two decades inside the IPA Effectiveness Databank,Peter Field has a verdict that should worry every marketer: the industry has been chasing the wrong metrics, on the wrong platforms, with the wrong creative— and the bill runs into the hundreds of billions. A conversation about brand, dullness, attention and why he’s still, somehow, an optimist.

Peter Field describes himself as “an effectiveness obsessive.” After twenty years of mining the UK IPA EffectivenessDatabank, the label feels less like self-deprecation than understatement. His work with Les Binet — most famously The Long and the Short of It — has reshaped how the industry thinks about brand and performance. More recently, with AdamMorgan and Dr Karen Nelson-Field, he has been putting numbers on what they callThe Cost of Dull. The numbers are uncomfortable. So we sat down with him for Adformatie to ask the obvious questions: how did we get here, and what do we do about it?

You started with Les Binet on The Long and the Short of It. What did you see in the data that nobody else was saying?

“Les and I have known each other since we were students. We were both crunching the IPA data, and the IPA actually said: do you guys know each other? You should work together. We’d been godparents to the same friend’s son for years — we just didn’t know we were both doing this.”

Their first joint publication,Marketing in the Era of Accountability (2007), was academic, data-heavy and largely ignored. The Long and the Short of It followed in 2012/13, and identified something that was just starting to bite: short-term effectiveness was undermining long-term effectiveness, and the industry was sliding in the wrong direction without realising it.

“I think we weren’t believed at the time. The readership of that particular book has actually grown over the years.Most business books spike and then slowly disappear. That one’s grown because at first the truth in it was disputed and derided. Anyone from a tech or performance-marketing background said: this is last millennium’s thinking. But the truth has come home to roost. We’ve seen dramatic declines ineffectiveness, and at the heart of the problem is this obsession with the short term.”

Was technology the driver?

“Absolutely. Businesses are in pursuit of certainty. CFOs hate risk. When you focus at the bottom of the funnel, you can see the impacts immediately. The mistake is to assume those impacts are entirely related to what you just did. I spend a euro on performance marketing, I get €1.20 back — this is good business. But a big chunk of that€1.20 is actually coming from investments you made in your brand months, even years, before. Without that, the €1.20 very rapidly starts to go south of a euro.”

“As your brand becomes unknown, invisible, untrusted, unliked, the performance machine demands more and more of your money. It’s a vicious cycle that a lot of businesses have got into.”

He is emphatic that he is not anti-performance. “The simple observation is that businesses are spending far, far too much of their budget on it. It’s not that the budgets aren’t big enough— they’re going on the wrong kind of advertising.”

“Performance marketing is seductive in some ways. It just happens to be wrong."

The 60/40 rule has become almost a meme.Does that frustrate you? And for marketers, the conversation with the CFO is often the bottleneck.

“We’ve always said 60/40 is a guideline, not a hard-and-fast rule. It’s the sweet spot for the average brand in the average category — and there aren’t many brands that are average.Start-ups need less, mature brands need more, premium brands need more, value brands less. But the point of a rule like 60/40, or the 95/5 rule, is that it’s a simple way to land an important truth. The danger is we get wrapped up in academic navel-gazing and lose the big picture: if you haven’t got a strong brand, you’re very unlikely to have a strong business.”

“As for the CFO conversation — you’ve got to be evidence-based. Most CFOs don’t come from a marketing background, but they’re very bright. When you put a coherent, evidence-based argument to a CFO about why brand-building matters, they get it. You’ve just got to believe in it yourself. There are young marketers out there who’ve been sucked into the performance model. It’s seductive in some ways. It just happens to be wrong.You cannot build long-term growth with performance marketing alone.”

Quantifying "The Cost of Dull" and the Danger of Cheap Reach

Let’s talk about The Cost of Dull. How did that project come about?

“Adam Morgan is an old friend. He came to me a couple of years ago and said: Peter, we’re all focused on the upside of great creativity — we’re not looking at the downside of getting it wrong. That immediately unlocked an issue I’d been struggling with in the IPA data: there are more dull campaigns in there than there should be. Why? Because they had huge budgets. These were businesses that could afford to throw a lot of money at it and not ask whether the advertising was actually working hard.”

He and Morgan started by quantifying the creative side. The number they kept hitting was around £10 million — the extra annual budget an average UK brand would need just to match the impact of top-quartile creative. Then System1 ran the analysis on the US market and put the aggregate wastage at just under $200 billion. “Roughly the GDP of Greece.These are not small numbers.”

Then came the second front: media.“Karen Nelson-Field’s contribution is what she calls attention elasticity. On low-attention platforms, creative never gets a look in. You can serve the best ad you want on Facebook and it’ll never get watched all the way through. People only really watch ads for one, one-and-a-half, maybe two seconds.” Karen ran the same wastage analysis on US media. Her number? Over $200 billion. “The GDPof Hungary. These are vast amounts of money being wasted by marketers who haven’t understood what really matters — getting attention for great creative, served on great platforms.”

“You can serve the best ad you want on Facebook — it’ll never get watched all the way through.”

That’s a hard message to bring into a planning meeting where someone keeps saying ‘but the reach is so cheap.’

“Ehrenberg-Bass has rightly told us for years that to build brands you have to build reach. The problem is that in a resource-tight world, that has led marketers to go for cheap reach. And when you go for cheap reach, you go for social.”

“But what we now know from Lumen and from Amplified Intelligence is that what really matters is attentive reach.Karen has shown that somewhere around two and a half seconds is the critical threshold at which you start to lay down brand memories. If you can’t get someone to watch your ad for two and a half seconds, you are not going to build the brand. Buying low-cost reach has become a very dangerous strategy.”

Flipping the Media Hierarchy: From CPM to Cost per Attentive Second

The platforms are not equal, he stresses. “TikTok is no better than Facebook, I’m told by the attention scientists. YouTube is much, much better. From an effectiveness standpoint, I like YouTube. I do not like most social platforms.”

Unilever has very publicly leaned into influencers. Brave or foolhardy?

“Putting 50% of a big mass-market brand budget into influencers carries a lot of risk. Individual influencers don’t deliver scale; you need a big portfolio of them — older, younger, in-between. Complexity is the enemy of effectiveness. The best campaign  susually have simplicity at their core. I wouldn’t put any of my money behind the success. I think they’ll rein back. There’s a sensible role for influencer investment — but well short of 50%.”

When influencers do work, he says, it’s because the influencer is themselves a brand built on trust. “When there’s genuine belief in the product, it works. When it’s just the influencer being bought, you’re back in a familiar pattern of ineffectiveness.”

You sound much more optimistic about connected TV.

“I’m very excited about it. YouTube has become a huge deliverer of TV — even in the UK now. The connected model l ets us join up the dots: we can target precisely for the bottom of the funnel,but we also know who we’re reaching, so we can build attentive reach. As an effectiveness platform, I’m hoping connected TV will relaunch TV. It seems to be happening in the US.”

His only caveat: in the US, connectedTV is being used almost exclusively as a bottom-of-funnel tool. “That’s notTV’s strongest suit. TV is a great brand-building platform with unparalleled attentive power. If you view it as a whole-funnel platform, it’s a fantastic new capability.”

You’ve described CPM as ‘cost per meaningless thousand.’ What should we be buying on?

“Karen calls it the stupidity of chasing CPM, because it is meaningless at the brand level. If you look at CPMs as your buying currency, you’ll go social. The lowest CPMs are on the Meta platforms. TV is pretty damn high. Cinema is off the scale. If, however, you use cost per attentive second — one of Lumen’s metrics — you get almost exactly the reverse hierarchy. TV becomes the cheapest. YouTube does very well. And suddenly the Meta platforms start to look goddamn expensive. That’s the reality.”

He sees the future as something more sophisticated still: a programmatic model where attention is priced microsecond by microsecond. “At two and a half seconds the value starts to build. At three seconds it’s even more valuable — but you’ve got a smaller audience. At five seconds, more valuable still, smaller audience again. Someone will use AI to build that model. And of course it’ll have to be done independently. We’ve had too many years of media platforms marking their own homework.”

“We’ve had too many years of mediaplatforms marking their own homework.”

The Intersection of AI, Human Creativity, and Emotional Salience

On AI — promise or problem?

“Both. The promise is enormous: predicting attention, modelling creative effectiveness, pricing impressions in real time. The problem is garbage in, garbage out. If you train AI on a platform’s own data, you get conclusions that conveniently favour the platform.We need independent models built by the attention scientists. And I don’t thinkAI will ever match human creativity. The great case studies of effectiveness were based on giant creative leaps — two and two making ten because of a great creative mind. What AI can do is execute great human ideas cheaply and quickly.The risk is that as it raises the floor, it lowers the ceiling. Everything starts to look the same — and that’s already part of the dullness problem.”

‘Happiness is a cigar called Hamlet’ still gets quoted. What killed the appetite for bold work?

“Performance marketing did a lot of the damage. If you’re closing a sale quickly, there’s no room for charm, humour, seduction. It’s just sell, sell, sell. As marketers realised there was no brand value in that, many reached for associations with good causes —purpose, political correctness, whatever you want to call it. Done badly, it’s done very badly. Done well, it can be immensely strong — if there’s a connection between the purpose and the business of your brand.”

The Dutch market, I tell him, can be blunt about the average tick-the-boxes campaign — vaguely green, vaguely inclusive, almost always forgettable. He nods.

“I’m with that. The important thing is that ads are well liked. Humour still works. Charm still works. Positive emotions still work. If the ad is well liked and well branded — meaning there’s a connection between the emotions and the business of the brand — it all works.We need to get back to trusting creative people and stop throwing too many rulebooks at them. If you give creative people the brief of ‘make people love our campaign’, and apply the rule book to ensure the branding is there, that’s where the gold lies.”

What’s next for you?

“I’m still very interested in dullness and attention. I’m going back through the IPA data to see whether overlaying creative and media attention metrics gives us better predictive power. I’d also love to prove the patterns we’ve seen in the UK with US data.”He pauses. “But I am genuinely optimistic. We’re finally beginning to understand the levers we have. And once we do, it’ll put right the big, big, big disastrous effects that have been going on in effectiveness over the last almost twenty years. I really do believe that.”
