Coca-Cola: Wallet of Happiness Honesty Test

An honesty test on a crowded Lima street

As part of an experiment in a very crowded Lima district in Peru, Coca-Cola with their agency McCann Erickson deliberately left a wallet containing $100 on the street. With it they tested people’s honesty.

A $100 question, asked in public

The brilliance is how quickly the situation reads. Find the wallet. Notice the money. Decide what kind of person you want to be, with nobody asking you anything.

In social experiment storytelling, a simple moral trigger creates instant comprehension and invites viewers to project themselves into the decision.

Why you keep watching

You are not just judging strangers. You are quietly measuring yourself against what you hope you would do. That internal comparison is the engine of the film.

What the experiment is trying to reveal

People’s honesty, observed in a real public setting through a simple, high-stakes trigger.

What to borrow

  • Choose a mechanic that is universal and legible without narration.
  • Keep production minimal so human reaction stays central.
  • Let the audience do the interpreting. A good social test creates its own debate.

Transparent Walls

For the PRE-SAFE® precrash system from Mercedes-Benz, ad Agency Jung von Matt in Germany made chaotic traffic intersections safer.

Everybody was able to look around the corners into the streets as if the walls were transparent, and could therefore detect potential hazards in time to avoid them. To achieve this, they used a camera to film what was going on around the corner. The images were then projected onto a 18/1-format billboard on a building corner so all motorists and cyclists could see them.

Big Noses Discount

BGH Air Conditioners in Argentina wanted to promote their new line of silent air conditioners. So agency Del Campo Nazca Saatchi & Saatchi came up with a whacky integrated advertising campaign called “Big Nose”.

Together they created the nose-o-meter, an in-store device capable of measuring noses. If your nose was big enough to touch the sensor, an alarm would go off and one could win a 25 percent discount!

At www.bignosebgh.com online visitors could upload their profile picture, in order to find out if their nose was big enough to win. The site also indicated where shoppers could find the nearest nose-o-meter to get a shot at the discount.
