Converj is a website where you can create online deliberative surveys, for free.

The problem

Most social-networks are "divergent", grouping us into "filter-bubbles" of like-minded people. These groups are comfortable, and the more time we spend there, the more we hear our own opinions reflected back to ourselves, and the more extreme we become in our views.

But when we leave our comfortable bubbles to make decisions for the larger society, the conflicting extreme opinions create chaos. Decision-making for our city, state, & nation becomes more and more difficult as people become further & further away from consensus.


We need a way to understand the world outside our own filter-bubble. We need a way to re-converge our isolated islands of belief, back into a single mainland society. We need a way for people to disagree, but still understand each other, and understand the facts. We need a way to plan a future together.

Converj is a forum that bursts filter-bubbles, encourages consensus in diverse groups, and improves the quality of group-decisions.

  • Reason-based voting

    When opinions conflict, voting alone does not bring opinions closer together. Competitive voting can even increase partisanship. But reason-based voting helps people to learn more, both about their own ideas, and about opposing ideas, finding new common ground.
  • Minimizing the knowledge burden

    We do not like to waste time. So Converj is designed to make it fast & easy for people to express their reasons, and to comprehend others' reasons.
  • Anti-abuse

    Some small fraction of people will try to break, misuse, and corrupt any forum. A forum for all people must allow subversion to exist, but limit the impact of their abuse. Converj is designed to allow noisy special-interests to speak their mind, without interrupting coherent deliberation.
  • For benefit

    Converj is run by a privately-held company, seeking profit only to operate sustainably.
