Voting method for everyone

Voting method for everyone

Method for finding the most acceptable consensus

Where can you apply Janeček Method (D21)?

Janeček Method (D21) is a novel voting method for collective decision-making. It provides multiple votes of plus and minus value. With multiple votes, we can express our preferences more accurately, and find consensus.

To the day, Janeček method (D21) has been successfully applied in municipalities and schools for “participatory budgeting”, a process in which people impacted by budgetary decisions are involved directly into the budget creation and allocation.

It can be used to prioritise topics, facilitate internal communication, and make the decision-making processes more democratic and efficient.

What makes our Method unique?

Our Method relies on the effect of multiple votes and also offers voters the opportunity of expressing a disagreement by casting a vote against (minus vote).

Multiple plus votes make it possible to identify overlaps between individual preferences, and therefore find a result that will be acceptable to the largest possible extent. The minus vote helps bring forward controversies or unacceptable options.

What else can the Method be used for?  

Beyond group decision-making, this method can be effective in opinion polling and surveying, in situations where we are looking to identify priorities, agreements, and controversies on specific topics.

We offer a free online version of the D21 online app which you can use to create your own poll about anything - simply and efficiently.

Practical example of using the Method in everyday life

A lunch that everyone will enjoy

A group of friends wants to go for a lunch. They are going to vote to choose the option that suits everyone's taste, if possible. There are several restaurants in the vicinity: Czech, French, Italian, Japanese, Mexican and Spanish; nearby is also McDonald’s and a small park where they could have a picnic. Voting with Janeček Method (D21) will help them quickly and conveniently choose the place that the most friends will enjoy. The summation of all plus votes will reveal which of the proposed options appeals to the most friends. The minus vote in the poll will help the friends with finding out which of the options is disliked, so they could better accommodate each other’s preferences.
