LiquidFeedback is more than Liquid Democracy

Topic based delegation

Liquid Democracy

Scalability through division of labor

The basic idea is a democratic system in which most issues are decided (or strongly suggested to representatives) by direct referendum. Considering nobody has enough time and knowledge for every issue, votes can be dynamically delegated by topic. Delegations are transitive and can be revoked at any time. Liquid Democracy is sometimes referred to as »Delegated« or »Proxy Voting«.

Collective moderation

Collective Moderation

Proportional representation of minorities

LiquidFeedback doesn't rely on a request commission and doesn't need a moderator. Instead, all participants gain equal rights in a scalable structured dicussion process where it is ensured that minorities gain a fair share of representation and that even individuals may put up their proposals for discussion. The system is designed in such way that noisy minorities won't harm other minorities in the discussion process.
+
Transparency

Fully Transparent Decision Process

Protection against non-transparent lobbying

Predefined rules and timings ensure that plans on decision processes are made public in time. Decisions are made by recorded vote only, and all voting-relevant data in LiquidFeedback is made available to all participants in both human– and machine–readable form. This enables a transparent decision-making process and ensures that participants can verify the voting procedure.

Preferential voting

Preferential Voting

Equal treatment of competing alternatives

LiquidFeedback doesn't ask predefined questions but encourages participants to suggest alternatives. A sophisticated voting system is facilitated to allow participants to express their opinions without necessity of tactical considerations. Its mathematical properties avoid vote–splitting and allow that similar proposals don't harm each other.

LiquidFeedback has been applied to various use cases

Parties

Political Parties

The natural habitat of LiquidFeedback
