The best of four decision methods
OneMind is a free group-decision tool that combines the reliable parts of four proven methods — the Delphi method, the Nominal Group Technique, deliberative democracy, and pairwise voting — into one automatic loop: anonymous independent ideas, iterative convergence, equal voice, and one-tap A-or-B rating.
OneMind isn't a new way to decide — it's a remix. It takes the reliable part of the Delphi method, Nominal Group Technique, deliberative democracy, and pairwise voting, and drops the one thing each gets wrong. Here's exactly how the engine works.

Every proven decision method is also broken in one specific way
Delphi converges, but it's slow and manual. Nominal Group Technique kills groupthink, but it doesn't scale or iterate. Deliberative polling gives everyone equal voice, but it needs moderators and never actually produces a decision. So in practice people skip all of them and just run a meeting or a poll. OneMind keeps the reliable half of each and runs the whole loop automatically.
How it works
- Independent ideas (from NGT). Everyone proposes privately before seeing anyone else's idea — the step that kills anchoring, the loudest voice, and groupthink. No one's thinking is contaminated by hearing yours first.
- Iterate to convergence (from Delphi). The group rates, a winner emerges, and the round repeats. When the same answer wins across rounds, that's genuine convergence — Delphi's signature loop, run automatically instead of by email.
- Equal voice, real decision (from deliberative democracy). Every participant's input counts the same, and the loop ends in an actual outcome — not just a visualization of who agrees with whom.
What makes OneMind different
- Rated two at a time (pairwise voting). You never score anything 0–100. You just answer "A or B?" — the one judgment humans are reliable at. A Bradley-Terry/Elo fit turns those taps into a full ranking. One-tap input is what lets a real group actually finish.
- Anonymous throughout. No one knows who proposed or rated what. Ideas compete on merit, not seniority or volume — the shared principle behind Delphi and NGT.
- No facilitator, no spreadsheets. OneMind runs the rounds, the tally, and the convergence check. What used to take weeks of manual facilitation happens in one sitting.

Frequently asked questions
How does OneMind actually decide?
Everyone proposes an idea privately, then rates ideas two at a time. OneMind fits those pairwise choices into a ranking using a Bradley-Terry/Elo model and repeats the round; when the same idea wins across rounds, that is the decision.
Why rate two at a time instead of scoring 0–100?
Humans are far more reliable answering 'A or B?' than assigning absolute scores. One-tap pairwise input is what lets a real group finish, and the taps still aggregate into a full ranking.
Which decision methods is OneMind based on?
It keeps the reliable half of four methods — independent ideas from the Nominal Group Technique, iterative convergence from the Delphi method, equal voice from deliberative democracy, and one-tap judgment from pairwise voting — and drops each one's failure mode.
Is it free and account-free?
Yes. OneMind is free, needs no account, and you can run a full decision loop in about 30 seconds.
