One introduction
A participating publisher may send one standardized experiment message to its own audience.
One email · One decision · Exactly €1
Would you send one euro to a complete stranger?
A transparent public experiment about trust, curiosity, and small voluntary decisions at scale.
- No product
- No reward
- No subscription
- No charitable claim
The entire proposition
You may voluntarily send exactly €1. You receive nothing in return. The money has no predetermined purpose. The aggregate outcome is intended to be published.
Method
A deliberately simple decision.
One euro is small enough to reduce the role of affordability, yet real enough to require an intentional action. Keeping the message and amount fixed makes outcomes across participating audiences easier to compare.
One clear choice
The recipient sees the same core proposition and decides whether to send exactly €1.
One aggregate result
Campaign-level visits, checkout starts, and completed payments are compared without building recipient profiles.
Transparency
Nothing hidden in the offer.
The experiment only works if the proposition is understood exactly as it is. There is no fictional cause, promised benefit, or implied return.
What it is
- An independent public experiment
- A voluntary payment of exactly €1

Data restraint
Measure the experiment, not the person.
The project is designed around campaign-level counts rather than individual recipient tracking.
Participating publishers keep control of their own mailing lists. The project does not use its own email tracking pixels.
Your decision
Send exactly €1.
By continuing, you confirm that the payment is voluntary, provides no product or reward, and has no predetermined use.

FAQ
Questions worth asking.
Why would anyone send €1?
There is no promised personal benefit. The decision itself—whether curiosity, trust, indifference, or another motive wins—is the subject of the experiment.
What happens to the money?
It remains with the project operator identified in the Legal Notice and has no predetermined use. The project does not claim a charitable or project-specific purpose.
Is this a donation?
No. It is not a tax-deductible charitable donation and no charitable organization is represented.
What information does the site retain?
The project records campaign-level metrics and limited technical payment references needed to verify completed transactions. It does not receive publisher mailing lists or create personal recipient profiles.
Will the results be public?
The intention is to publish an aggregated account of the methodology, results, limitations, and any material changes made after launch.
