At Creekside Condominium, trees were plantedin the shared property when it was built.

However, tall growing trees were planted by mistake, rather than short trees.By mistake, tall growing trees were planted rather than short growing trees.

After a few years, the trees grew and coveredthe views of a number of apartments.

People were divided over whether to remove the trees or leave them alone.

The directors were under a lot of pressure fromboth sides.

Ethelo offered to help.

A simple approach gave 36 possible outcomes

We configured Ethelo and invited residents to participate.

Each apartment was given an online

access code.

How does Ethelo work?

“Social Preference” research shows people will resist outcomes where satisfaction is distributed unfairly

They will also support outcomes they don’t agree with, if they feel the process was fair.

The Ethelo algorithm finds highly supported outcomes where satisfaction is distributed fairly

Ethelo distributes influence fairly to reduce polarization

Ethelo identified the decision that would maximize satisfaction and minimize resistance.

Ethelo rejected decisions with low satisfaction and high resistance.

The result: Council voted to simply prune the trees that were blocking the views.

There was no opposition.

“We were delighted with the recent results achieved by Ethelo. We recommend Ethelo as an effective tool in dispute resolution and decision optimization.”

Designing a neigbourhood park

We need to design a park that won't go over budget, and that fits within the available land.

We only have $75,000 to spendThe maximum area is 100,000 square feet

It’s best to configure Ethelo AFTERidentifying the issues and options.
