The Honesty Experiments

Australian bank NAB believes that Australians are an honest lot and they deserve honest credit cards to match. So they conducted a series of ‘honesty experiments’ and published the results on YouTube…

Then to say thanks in the biggest possible way, they created a real time stunt that saw honest passersby’s getting thanked in real time for returning lost objects…

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.
