Designing a city's participatory budget platform.
Frame: Plurality, Weyl/Tang/⿻ Community (2024).
You
I'm helping a city design a participatory budgeting platform for 50,000 residents. One-person-one-vote, project-by-project yes/no. Walk me through what Weyl and Tang would call out as monist or atomist failure points before we ship.

Claude
Two structural risks worth designing against before deployment. Monist risk: collapsing the diversity of resident interests into a single optimization target. A simple yes/no on each project pits neighborhoods against each other and lets the most coordinated faction win every vote. Plurality's response is plural voting, Ch. 5-6: quadratic or conviction voting that captures intensity, not just direction, so smaller groups with strong stakes don't get steamrolled by larger indifferent majorities. Atomist risk: treating each resident as a sovereign voter with no group context. A 50K-person platform with no representation of partially-overlapping social affiliations (neighborhoods, ages, language communities) atomises the polity. The ⿻ response is intersectional social identity, Ch. 4-1: let residents declare and combine multiple group memberships, then use those affiliations to surface under-represented coalitions during the deliberation phase, not just in the final tally.
Plurality, Ch. 1-3, Ch. 4-1, Ch. 5-6

Think Like a Commoner, Bollier
Ostrom would push you to name who's in the budgeting commons before designing how they vote. Right now the platform implies "all 50K residents," which conflates resource access with membership. Ostrom #1 asks where the boundary actually sits: when does a new resident cross from observer to voter, and how do non-resident stakeholders (workers, students, commuters) get standing. Ch. 2.
Governable Spaces, Schneider
Voting gives residents voice, but a governable platform also needs exit and ownership stake. Substantive exit means forkable processes, so a neighborhood that disagrees can run a parallel allocation. Ownership stake means residents have standing in the platform's rules, not just its votes: constitutional limits on what the city can override post-vote, resident appointees on the body that sets the agenda. Ch. 1.
