An App to Pick a Voting Mechanism
1) Set priorities for evaluation criteria
For each criterion, pick its importance. (High=2 points, Medium=1, Low=0).
Fairness / Equality
Do all participants have equal influence on the outcome? High priority emphasizes equal treatment and impartiality.
Low
Medium
High
Minority Protection
How much should smaller or dissenting groups be shielded from being overridden by a simple majority?
Low
Medium
High
Resistance to Strategic Manipulation
Should the rule discourage insincere or tactical voting by making manipulation less rewarding?
Low
Medium
High
Preference Expressiveness
Is it important to capture ranked orders or intensity of preferences, not just a single choice?
Low
Medium
High
Epistemic / Information Aggregation
Should the mechanism combine dispersed knowledge to approximate a correct or well-informed outcome?
Low
Medium
High
Decisiveness / Speed
Is producing a clear decision quickly more valuable than maximizing deliberation or inclusiveness?
Low
Medium
High
Cognitive Simplicity
Should the process be easy for participants to understand and execute correctly end-to-end?
Low
Medium
High
Scalability
Must the mechanism operate efficiently with large groups and/or many alternatives?

Transparency & Accountability
Is it important that voters and observers can verify how inputs led to the outcome and who is responsible?

Method: how scoring works
Each selected criterion is assigned a weight: High=2, Medium=1, Low=0. Each mechanism has a baseline score (0–3) for each criterion. We compute a weighted sum and then apply context adjustments (+/−) based on group size, number of alternatives, reversibility, and deliberation mode.
