Voting method for everyone

Method for finding consensus

Where can you apply Janeček Method (D21)?

The Janeček Method (D21) is a novel voting method for collective decision-making. With multiple votes, we can express our preferences more precisely and find consensus.

To the day, the Janeček Method (D21) has been successfully applied by many municipalities and schools in their participatory budgeting processes, allowing individuals to prioritize public spending projects and to make decisions on how money is spent. 

The Janeček Method (D21) can be used to prioritise topics, facilitate communication and deliberation, and make the decision-making processes more transparent, fair and efficient.

What makes our Method unique?

The basic feature of the Janeček Method is that the voter can identify in a single ballot more than one preference by applying Systematically Capped Multiple Votes. This introduces a new dimension to the voting methodology. Multiple Plus votes make it possible to identify overlaps between individual preferences, and hence find a consensual outcome acceptable by the majority. An option of a Minus vote helps uncover controversial and 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.

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.
