The unheeded instruction

Everyone has been told what to do and keeps doing otherwise, so more telling only adds volume.

What do you do when the sign, the rule and the campaign have all failed?

you are in this shape if

the moves

Redesign the moment, not the message
Change what the person is physically doing at the instant of choice — a target to aim at, a staircase that plays, a queue that walks — so the right act needs no persuasion.
Flip the payoff
Turn compliance into something with positive expected value instead of merely the absence of punishment.
Make the consequence visible
Show the invisible result of the behaviour — the bacteria, the crash, the cost — where the behaviour happens.

where it was solved

  1. 1768James Cook / Royal Navy (HMS Endeavour, HMS Resolution)Naval logistics / public healthWithin roughly a week, according to Cook's own journal, sailors began requesting a share of the officers' sauerkraut on their own initiative. Cook then 'allowed' it to the crew as if granting a privilege rather than issuing the order he'd wanted to issue from the start — the same substance, the same mandatory intent, delivered as something crewmen had talked their way into instead of something imposed on them.Cook's first circumnavigation (1768–1771) lost no men to scurvy, an outcome the Victualling Board credited substantially to the sauerkraut ration reaching sufficient consumption; the same tactic and a much larger sauerkraut supply were carried on Cook's second voyage (1772–1775), which is likewise recorded as scurvy-death-free among a crew of over 100 men across three years at sea.
  2. 1984New York City Transit AuthorityPublic transitNew Transit Authority president David Gunn's Clean Car Program didn't add patrols to catch writers — it removed the reward: any car tagged at the end of its run was pulled from service and scrubbed before it carried a passenger again, so a piece was never seen moving.Graffiti and criminal-mischief arrests fell from 1,435 in 1985 to just 215 in 1987 — an 85% drop — and by 1988 about 5,000 of the system's 6,100 cars (82%) were graffiti-free; by May 1989 the MTA declared the entire fleet clean, a state it held for decades.
  3. 1991Schiphol AirportFacilitiesA cleaning manager who remembered a barracks trick had a fly etched by the drain: give men something to aim at and they aim.Spillage reportedly fell ~80% and cleaning costs ~8% (the figures are 'very empirical', by their own admission). Thaler's favourite nudge; copied worldwide.
  4. 1995City of Bogotá (Mayor Antanas Mockus)Traffic safetyNewly elected mayor and former philosophy professor Antanas Mockus bet that Colombians feared public ridicule more than fines, so in 1995 he deployed more than 400 trained mimes to city intersections to silently mock jaywalkers and reckless drivers — and applaud those who obeyed — instead of adding more ticket-writing police.Traffic fatalities in the areas the mimes worked fell by more than half during Mockus's tenure, and the tactic became a signature of his wider 'citizen culture' program, later copied by other Latin American cities.
  5. 1998UK Medicines Control AgencyPublic health regulationIn September 1998 the UK's Medicines Control Agency capped over-the-counter paracetamol sales at 32 tablets per pack in pharmacies and 16 in other shops, sold in push-through blister packaging rather than bottles. The law didn't ask anyone to be less impulsive; it added a few extra minutes of foil-popping friction, and a hard ceiling on how many tablets a single purchase could put in someone's hands, at exactly the point where an overdose is decided on impulse.A 2013 study covering the 11¼ years after the law found a 43% reduction in deaths from paracetamol poisoning with suicide or open-verdict rulings in England and Wales — about 765 fewer deaths (990 including recorded accidental poisonings) than expected — and a 61% reduction in registrations for liver-transplant listing due to paracetamol-induced liver damage.
  6. 1999Iceland (Icelandic Centre for Social Research and Analysis, with Reykjavík)Public healthResearchers, including American psychology professor Harvey Milkman and Icelandic colleagues Inga Dóra Sigfúsdóttir and Jón Sigfússon, reasoned teenagers used substances to chase a mood — a 'natural high' — that a lecture couldn't replace. Starting in 1999, the state funded sports, music and arts for every teenager (with subsidy cards so low-income families could afford them), enforced evening curfews for under-16s, and pushed for more scheduled parent-child time, instead of expanding drug-awareness programming.Icelandic 15–16-year-olds reporting drunkenness in the past month fell from 42% in 1998 to 5% in 2016, and daily cigarette smoking fell from 23% to 3% over the same period; weekly organised-sport participation nearly doubled, from 24% to 42%.
  7. 2003Municipality of Drachten (traffic engineer Hans Monderman)Public infrastructure / traffic safetyIn 2003 Monderman redesigned Laweiplein as a 'shared space': a single paved square with no traffic lights, no curbs separating cars from cyclists and pedestrians, and no lane markings, built around a small roundabout and fountains instead of a signal box. Drivers, cyclists and pedestrians were left to negotiate the crossing by eye contact and yielded right-of-way instead of by obeying a light.Annual accidents at the junction fell from roughly nine per year before the redesign to about one per year afterward, even as traffic volume held around 22,000 vehicles a day and average crossing time dropped from about 50 seconds to 30. Cyclist and motorist self-reported feelings of safety slightly declined even as the actual accident count fell — the discomfort was the mechanism, not a side effect of it.
  8. 2008Israeli Ministry of Health / KnessetOrgan transplantation policyIsrael's 2008 Organ Transplantation Law, with priority allocation taking effect in 2010, gives registered donors — and, after a three-year wait, their first-degree relatives — bonus priority points on the transplant waiting list if they ever need an organ themselves. Anyone who had already donated an organ, or whose immediate family member became a deceased donor, receives top priority immediately, no waiting period. The pitch to the public shifted from 'help a stranger' to 'this list favors people who are already on it.'The clearest attributable effect is on the harder of the two numbers: family consent to donation after death, which is where most registration campaigns fail even when the deceased carried a donor card. Consent rose from roughly 42% in 2007 to 62% by 2016. Donor-card sign-ups spiked during the 2011–2013 publicity push but later leveled off, and Israel's overall deceased-donor rate — about 10 per million people in 2016 — still trailed most Western European countries, so the law changed behavior at the family's bedside more clearly than it changed the national donation rate.
  9. 2008Save the Elephants (Dr. Lucy King)Wildlife conservationSave the Elephants strung farm boundaries with beehives hung on wires a few meters apart, connected so that one disturbed hive shakes the whole line — an elephant brushing the fence triggers a swarm and retreats before reaching the crop, no physical barrier required. King's confirming behavioral study ran in 2007; the first beehive-fence field trials began in Kenya in 2008.Beehive fences deterred elephants roughly 80% of the time in King's field trials, and 61% of surveyed farmers rated them more effective than the thorn barriers and fires they'd used before. The bees' honey adds $50–200 to a family's income per harvest on top of the crop saved.
  10. 2009East Japan Railway Company (JR East)Public transitAfter suicides on its lines rose from 42 in 2007 to 68, JR East fitted blue LED lights above the ends of platforms — the isolated spot where jumps cluster — across all 29 Yamanote Line stations in 2009, betting that a colour associated with calm would interrupt an impulsive act more cheaply than any physical barrier.A 2013 University of Tokyo study across 71 stations over a decade found an 84% drop in suicide attempts at stations with the lights (a wide 14–97% confidence interval, and a 2014 re-analysis argued the effect was overstated) — but the lights cost a fraction of platform screen doors, and the practice spread to other Japanese railways regardless.
  11. 2009VolkswagenPublic transit / behavioral designOvernight, DDB Stockholm wired every step of the Odenplan staircase to play a piano note when stepped on, turning the staircase itself into a playable instrument next to the escalator — no signage, no health message, just an instrument nobody was told to use.Widely and consistently reported at 66% more commuters choosing the stairs over the escalator compared with a normal day. The primary Volkswagen press release could not be directly confirmed here — it blocked automated access on repeated attempts — but the figure is stable across every independent secondary account checked, including trade press. The film became the flagship demonstration of Volkswagen's 'Fun Theory' campaign.
  12. 2010Swedish Transport Administration × Kevin RichardsonRoad safetyGame designer Kevin Richardson's winning Fun Theory entry photographed everyone: speeders paid fines that funded a cash lottery for the drivers under the limit.Average speed at the camera fell 22% (32→25 km/h) in the three-day pilot. Never institutionalised — which is part of the lesson.
  13. 2012Metro Trains MelbournePublic transit safetyMcCann Melbourne dropped the warning-poster format and released 'Dumb Ways to Die' — a cheerful cartoon song about absurd deaths in general, with actual train-safety lines buried in the final verses. Nobody was told to be careful; they were given a song stuck in their head.Near-miss accidents fell 21% among under-25s in the three months after launch, beating Metro's 10% target; near-misses ran 20% below the annual average the following year (a 30% year-on-year drop for the same season). The video passed 350 million YouTube views.
  14. 2016Government of OntarioPublic health / organ donation registriesResearchers tested reframing the donor-registration prompt from an altruism ask to a reciprocity question — 'If you needed a transplant, would you have one?' — forcing renewers to weigh their own self-interest before declining. Ontario rolled the wording into its province-wide driver's-licence renewal form.In the field trial (n=3,330), new registrations jumped from 4.1% to 7.4% of renewers, an ~80% relative increase, for the cost of a sentence. Ontario adopted a simplified registration form using the reciprocity prompt province-wide in 2016.
  15. 2016Sandy Hook Promise (with BBDO New York)Public safety / violence preventionThe film let viewers do exactly what real bystanders do: follow the obvious foreground story and miss the warning signs sitting in plain, unhighlighted sight the whole time. Only in the final seconds does on-screen text state 'While you were watching Evan, another student was showing signs of planning a shooting. But no one noticed' — turning the viewer's own attention lapse, which just happened to them in real time, into the demonstration of the problem, rather than describing the problem to them abstractly.'Evan' received over 150 million views, was named to Adweek's list of the 10 best ads of 2016, won multiple awards including recognition at Cannes, and drove what Sandy Hook Promise co-founder Mark Barden described as a major uptick in the organization's visibility, breaking out of advertising trade coverage into mainstream press including CNN and The New York Times.
  16. 2017Behavioural Economics Team of the Australian Government (BETA) / Australian Taxation OfficeTax administrationIn a trial starting March 2017, the ATO sent letters not to taxpayers but to roughly 1,150 of their tax agents, informing each agent that their clients' work-related-expense claims collectively ranked among the riskiest percentage band compared with other agents' client books, and noting that the ATO's data-analytics systems flag larger-than-expected claims. No taxpayer received anything; the accountant preparing the numbers did.Agents who received the letter saw their clients' claims fall by $2.2 million and tax paid rise by $0.9 million relative to a similarly sized control group of agents. The ATO projected that scaling the letter to its full at-risk agent population would cut claims by about $4.4 million and lift tax paid by about $1.7 million.
  17. 2017Government of PalauTourism and environmental policyInstead of more warning signs at the water's edge, Palau wrote the pledge into its immigration law: every visitor signs a personalized promise to act environmentally and culturally responsibly, and an immigration officer stamps it into their passport before they can clear customs. Breaking it carries fines of up to $1 million.A 2018 Havas survey found 96% of visitors said the pledge made them consider their actions more closely, and 65% said they used its principles to remind others during their stay, per a 2020 academic case study that cites the Havas figures. Palau became the first country to make an environmental pledge a legal condition of entry.
  18. 2021Claire's Place Foundation (with Woojer)Medical devices / patient adherence'Sick Beats' plays a curated catalog of therapeutic 40 Hz music through Spotify via eight transducers built into the vest, so the exact physical vibration medically required to clear the lungs is delivered as the bassline of a song the wearer chose, rather than as an undifferentiated mechanical pounding — the treatment dose and the music are the same physical event, not two things happening at once.Sick Beats won the Cannes Lions Pharma Grand Prix and multiple additional Cannes Lions Health awards in 2021, and a D&AD Pencil the same year, recognized specifically for reframing a dreaded compliance device into something patients wanted to use — converting the core adherence problem (avoidance of an unpleasant necessary routine) into a product built around active desire to use it.
  19. 2022Korean National Police Agency (with Cheil Worldwide)Public safetyAfter dialing 112 and giving no verbal response, a caller taps any number key twice — inspired by a knock, or Morse code. The call handler reads the double-tap as a distress signal and sends a text link back: opening it silently shares live location and camera feed with the officer, and opens a chat window disguised as a search-engine page so the caller can type without an abuser recognizing it as a police channel.In the first month after the September 2022 launch, the system reportedly sent 5,749 links to silent callers. South Korea subsequently made the double-tap gesture an official part of the 112 protocol, and the campaign won the Glass: The Lion for Change Grand Prix at Cannes Lions 2023. Beyond that first-month count and individually reported rescues, there is no public multi-year usage or case-resolution dataset — the strongest verifiable claims are the launch-month figure, the formal protocol adoption, and the award record; broader long-run impact is not independently documented.
  20. 2023Dulux Indonesia (with INNOCEAN Indonesia)Public health / paint & coatingsRather than add a chemical or mechanical fly-control layer to unchanged canteen furniture, Dulux repainted canteen tables, benches and walls yellow — turning an existing, unavoidable surface (the furniture itself) into the fly deterrent, with zero ongoing spraying, trapping, or chemical exposure near food.The pilot experiment confirmed yellow's fly-repelling effect on canteen surfaces, prompting a wider rollout to additional schools; more than five thousand students had eaten in yellow-painted canteens within two months of launch, with no chemical fly control needed in those spaces.
  21. 2024Dublin Samaritans / Droga5 DublinNon-profit / volunteer recruitmentWith Droga5 Dublin, Samaritans bought inexpensive ad placements inside podcasts from the Headstuff network and other audio programming, timed to run at the 26-minute mark of listening — the same length as one of its calls — with hosts speaking directly to whoever was still listening that far in about becoming a volunteer, on the reasoning that a person who stays with one voice for 26 minutes has already shown the core skill Samaritans needed. A companion live storytelling event with Seanchoíche extended the same idea offline.On a media budget of about €2,500, the campaign drove roughly a 250-260% increase in volunteer applications versus the prior year (Effie Awards Europe's own case materials cite 260%; other coverage of the same campaign reports 250%), a 32% click-through rate from the landing page to the application form, and enough new recruits to fill two full training classes.
  22. 2024SpecsaversOptical and hearing retailGolin London re-recorded Rick Astley's 'Never Gonna Give You Up' with the lyrics swapped for commonly misheard mondegreens, so listeners experienced the actual symptom of hearing loss — mishearing words — as the punchline, instead of being warned about it in an ad.A 138% increase in hearing-loss-related Google searches and hearing aids as the UK's #1 trending topic online, plus a 66% increase in Specsavers hearing-test bookings. The work won two Cannes Lions Grand Prix, in PR and Audio & Radio.
  23. 2024UN WomenPublic policy and human rights advocacyInstead of a public statistics campaign, UN Women and Impact BBDO mailed personalized wedding invitation cards — illustrated by children aged 5 to 15 — directly to Pakistani lawmakers, each inviting them by name to a specific child's wedding. A legislator couldn't deflect an invitation to the public; they had to personally respond to it.Lawmakers who received the cards held them up at Pakistan's National Assembly. On March 7, 2023 — about 14 months after the campaign reportedly launched — the Federal Shariat Court ruled 18 as the minimum legal marriage age; press coverage credits the campaign as a contributing factor, though none of the sources read for this case establish direct causation between the mailing and the court's decision.
