Sir John Hegarty Calls Bullshit on AI Hype and the Market Research Echo Chamber

Autumn’s here, agency suits are dusting off their ‘strategic’ blazers, and Sir John Hegarty just torched half the marketing industry before lunch. At the Festival of Marketing this week, the old lion of advertising dropped his usual diplomatic filter and called out the lazy cargo cults propping up today’s campaigns. No, he doesn’t think AI is the Second Coming—unless your idea of a miracle is another thousand variations of bland banner ads.

Hegarty’s main target? The bloated, repetitive, and frankly pointless market research that’s metastasized across every major brand like invasive bamboo. He’s seen the pitch decks: over-researched, under-imagined, and terrified of any idea that isn’t already focus-grouped to death. His words, not mine: “When research replaces insight, you’re left with mediocrity.” Amen. Let’s stop pretending that another five-figure survey will save you from your own creative cowardice.

And for the AI cultists—yes, the ones still peddling LinkedIn carousels with ‘Ten Prompts That Will 10x Your Marketing Funnel’—Hegarty’s not buying it. Sure, he admits AI has ‘possibilities’, but he’s seen too many marketers already replace thinking with prompt engineering. The result? A tidal wave of content so generic, you’d think half the industry moonlights for Squarespace.

His beef isn’t with technology itself, but with the industry’s addiction to tools over taste. He draws a brutal parallel to the Catholic Church: “If you want to see how brands lose relevance, look at how faith lost its grip when it stopped inspiring and just started counting heads.” Marketing, he says, needs a bit more soul—and a lot fewer dashboards.

If you’re expecting a feel-good panel on ‘the future of advertising’ this month, brace yourself for Hegarty’s home truths. He’s reminding everyone that real work is uncomfortable, original, and rarely comes from a spreadsheet. Skip the survey budget, hire someone who can actually write, and if you must use AI—make sure it’s not just regurgitating the same old brand soup.
