Irrational Beliefs

Six ways to let irrational thinking do the rational work.
Irrational Beliefs

People avoid the number 13. They blow on dice before rolling them. They insist a footballer called Zé is the difference between glory and heartbreak. None of that is rational. None of it is going away. The brands in this article didn't argue with it — they rolled with it. Here are six tactics that let irrational thinking do the rational work.

  1. Turn a Conspiracy Theory Into a Brand Platform
  2. Embrace a Superstition That Already Belongs to Your Product
  3. Manufacture a Superstition to Drive a Behaviour
  4. Unearth a Folklore Belief and Make It Your Proposition
  5. Make the Audience the Ritual Keepers
  6. Weaponise Bad Luck Against Your Rivals

1. Turn a Conspiracy Theory Into a Brand Platform

Find a pattern too convenient to be coincidence — then make your brand the one who blew the lid off it.

The Illemonati — 7UP, BBH USA, 2026

For decades, lemon has enjoyed top billing. Lemon-lime drinks. Lemon freshness. A twist of lemon. Even the lemon emoji arrived before lime got anything resembling equal representation. Coincidence? Apparently not. To launch its new lime-first recipe, 7UP exposed the Illemonati: a shadowy organisation responsible for keeping “Big Lemon” in power. Films, historical evidence, anonymous investigators and a lime-led “Rezestance” turned a product reformulation into the overthrow of a centuries-old citrus conspiracy..

Football Is Food — Uber Eats, 2024

Uber Eats had data showing orders spiked when its ads ran alongside food brand commercials — proof that football makes people hungry. The answer was to take that insight to its most paranoid conclusion: what if football was always a conspiracy to sell food? What if the goalposts were two french fries? What if Julius Peppers, CJ Ham and Jerry Rice weren't a coincidence? Matthew McConaughey played conspiracy theorist-in-chief across an entire NFL season, culminating at Super Bowl LIX — a game named after a bowl, at a stadium named after a salad. The campaign earned $225 million in ad value and drove a 3x quarter-on-quarter increase in app sessions.

The creative move: Find a convention everyone accepts without questioning. Invent the hidden organisation responsible for keeping it that way. Then make your product change the rebellion against it

Expedition Iceland (Icelandair, Kubbco, 2024) inherited a different accusation. AI-generated imagery had made Iceland a running joke in sceptical corners of the internet — it was too 'perfect'. Rather than rebut it, Icelandair sent a conspiracy bro and his increasingly exasperated companion to investigate on camera. The mockumentary works through the evidence methodically and the format mirrors the exact content culture that produces this kind of doubt — which means the film travels inside the same feeds carrying the conspiracy. By the end, the bro still can't quite say it out loud. The accusation just runs out of road. Over 36 million views and a 51% interaction rate.


2. Embrace a Superstition That Already Belongs to Your Product

Find the pre-existing folk belief attached to your category — and lean into it rather than away from it.

Unlucky Sponsor — Cris-Sal, Paradais DDB, 2022

Cris-Sal was rejected as a sponsor of Ecuador's national football team because salt is considered bad luck in South American culture. Rather than find another platform, the brand accepted the premise entirely — and sponsored Ecuador's opponents instead. Billboards inside and outside stadiums wished opposing teams good luck, complete with a Cris-Sal shaker dusting salt over the message. Ecuador reached Qatar 2022. Their opponents were plagued by injuries and red cards. The campaign generated 41 million impressions for a brand most of the world had never heard of. See campaign ->

The creative move: Look for a superstition that makes your product unusually lucky, unlucky or powerful. Don’t correct the belief. Follow its logic until it gives the brand a role nobody else could credibly occupy.
