The Honesty Index: What Happens When You Drop Your Wallet in Tokyo, Naples, Mumbai, and Zurich

In 2019, a team of behavioural economists led by Alain Cohn at the University of Michigan conducted one of the largest honesty experiments ever attempted. They "lost" 17,303 wallets across 355 cities in 40 countries. Each wallet contained a grocery list, a key, and business cards with an email address. Half contained no money. The other half held $13.45 in local currency.

The results, published in Science, upended everything we thought we knew about human nature.

In virtually every country, people were more likely to return wallets that contained money than empty ones. More cash, more honesty. The economists expected the opposite. Homo economicus, rational, self-interested, the protagonist of every introductory textbook, would pocket the cash and move on. Instead, real humans, from Jakarta to Johannesburg, seemed to feel a greater moral obligation when the stakes were higher.

But the return rates varied wildly by country. And that variance tells a story more interesting than any economic model.

Tokyo: Where Honesty Is Infrastructure

Japan returned wallets at the highest rate in the study: over 80%. This surprised exactly no one who has spent time in Tokyo, where the lost-and-found system operates with the precision of a Swiss railway and the moral seriousness of a Confucian temple.

The Tokyo Metropolitan Police's lost property centre is a seven-storey building in Iidabashi that processes over 4 million items annually. Umbrellas account for the largest category, roughly 340,000 per year, followed by clothing, phones, and wallets. The system works because Japan has the Ishitsubutsu-hō (Lost Property Act), a law dating to 1899 that establishes a clear protocol: found items go to the police, the owner has three months to claim them, and the finder is entitled to between 5% and 20% of the item's value as a reward.

But the law alone doesn't explain the culture. In Japan, returning a found item isn't an act of exceptional virtue; it's baseline behaviour. Not returning it would be a source of profound shame, not just personal, but familial. The Japanese concept of meiwaku (causing trouble to others) creates a powerful social incentive: keeping someone's lost wallet causes them meiwaku, and causing meiwaku is among the worst social transgressions imaginable.

An ekTAG in Tokyo would be almost redundant, except that even the Japanese system breaks down for foreign tourists who don't speak the language and can't navigate a police report in kanji. A scannable QR code that bridges the language gap? Even Tokyo could use that.

Naples: The Art of the Negotiation

Italy, in the wallet study, returned about 51% of wallets, middling by European standards. But averages are deceiving. Northern Italy (Milan, Turin) returned at rates closer to Scandinavia. Southern Italy, particularly Naples, operates by different rules.

Naples is a city where the concept of l'arte di arrangiarsi, the art of getting by, of making do, of improvising, is not a character flaw but a survival philosophy refined over centuries of foreign occupation, volcanic eruption, and municipal corruption. If you drop your wallet in the Spanish Quarter, the most likely outcome is a complex social transaction. A stranger might find it, remove the cash, then mail the wallet back to you with the documents intact and a handwritten note of apology. This is not theft, exactly. It's redistribution with manners.

Diego Maradona, Naples' secular saint, once said he was drawn to the city because "it was the only place in the world where the people were more crazy than me." The Neapolitan relationship with found objects reflects this glorious chaos: items aren't so much lost as temporarily reassigned by fate. A friend in Naples once told me, with complete sincerity, that finding a wallet is "a gift from San Gennaro" and that refusing a saint's gift would be blasphemous.

One imagines an ekTAG in Naples generating not just a return notification but the beginning of a beautiful, chaotic friendship.

Mumbai: The Dabbawalas Already Figured This Out

India presents a paradox. The wallet study didn't include India in its main dataset (a frustrating omission, given that one-sixth of humanity lives there), but smaller local studies and journalistic experiments tell a complicated story.

In 2018, the Hindustan Times dropped 10 wallets across Mumbai. Seven were returned, a 70% rate that would place India respectably above much of Europe. But the mechanism was fascinating. In most Western countries, finders handed wallets to institutions: police stations, shop owners, hotel reception desks. In Mumbai, finders overwhelmingly attempted personal returns. They'd call the phone number on a business card, track down the address on the ID, even take an auto-rickshaw across the city to hand-deliver the wallet. The impulse wasn't institutional; it was interpersonal.

This makes perfect sense in a culture where the concept of dharma, duty, righteousness, cosmic order, permeates daily life. Returning a lost item isn't about following a rule. It's about maintaining the moral fabric of the universe. No pressure.

Mumbai is also home to the dabbawalas, the legendary lunchbox delivery network that transports 200,000 tiffins daily with an error rate that would make Six Sigma consultants weep. They achieve this using a colour-coded tagging system painted on each lunchbox. No GPS. No apps. Just tags.

The dabbawalas understood, long before Silicon Valley, that the simplest tagging system is the most resilient one. A QR code on a lunch tin, or a set of car keys, or a suitcase at Chhatrapati Shivaji International Airport, follows the same logic: make the right action effortless, and people will take it. ekTAG is the dabbawalas' wisdom, digitised.

Zurich: Honesty as Civic Engineering

Switzerland returned wallets at 74% in the Cohn study, high, but not the highest, which confuses the Swiss tremendously. The Swiss model of honesty is fundamentally institutional. It's not that Swiss people are inherently more honest (though they'd like you to think so); it's that Switzerland has engineered systems that make dishonesty inconvenient.

Swiss lost-and-found offices (Fundbüro) operate with Germanic efficiency and are connected to national databases. Reporting a found item is easy and expected. The social contract is explicit: you live in a country that works because everyone follows the rules. Defecting from this contract marks you as someone who probably also jaywalks, which in Zurich is the moral equivalent of arson.

The Swiss relationship with lost property is, in a word, procedural. There is a form. You fill in the form. The form is processed. The item is returned. Nobody hugs. Nobody becomes friends. The system works.

This is the quiet genius of a product like ekTAG: it works across all these cultural modes. In Tokyo, it streamlines an already virtuous system. In Naples, it gives good-hearted chaos a clear channel. In Mumbai, it matches the instinct for personal return with a tool that doesn't require a cross-city rickshaw ride. In Zurich, it is, essentially, the form, digital, efficient, requiring no human warmth whatsoever.

The Wallet Drop You Can Run Yourself

Here's a thought experiment. Tomorrow morning, leave your keychain, tagged with an ekTAG, at a coffee shop. Not your wallet. Not your phone. Your keys, which are useless to anyone who doesn't live in your house. See what happens.

If the behavioural economists are right, the absence of monetary value might actually decrease the return rate, people feel less guilt about not returning something worthless to a stranger. But a QR tag changes the calculus entirely. It's not that the finder suddenly develops a conscience; it's that the tag removes every barrier between their good intention and the act of returning. Scan, tap, done. Anonymous. Effortless. No rickshaw required.

The Cohn study's most striking finding wasn't about honesty at all. It was about friction. In countries where returning items was easy, clear systems, visible drop-off points, simple processes, return rates were high. Where it was difficult, rates plummeted. The variable wasn't morality. It was infrastructure.

ekTAG is infrastructure for honesty. It doesn't make people better. It makes being good easier.

And that, the behavioural economists would tell you, is the only intervention that has ever reliably worked.
