Argument mapping
Most tools that help with a hard question try to give you an answer. Argument mapping does the opposite: it lays out the full structure of a debate — positions, arguments, counter-arguments, and the evidence under each — as a navigable map, so you can see the whole landscape of reasoning and make up your own mind.
The Society Library
Section titled “The Society Library”The most ambitious example is The Society Library, a nonprofit founded by Jamie Joyce. It builds what it calls deliberation databases — debate maps on complex, contested issues like the Diablo Canyon nuclear plant, COVID-19, and AI. For a single map, analysts (often trained librarians) comb through thousands of artefacts — government documents, scholarly articles, books, documentaries, even TikToks — and decompose them into an ontology of claims and evidence. The chains of reasoning can run twenty layers deep, and because a premise relevant in one place reappears elsewhere, the result is really a graph, not a tree. The Diablo Canyon map took roughly 8,000 research hours — two full-time years — which is exactly the point: it does, once, the work no individual citizen has time to do.
The method rests on a few principles:
- Steel-manning every viewpoint — making each argument as robust as possible regardless of who said it. “The truth is the truth no matter who says it”; even sources widely dismissed sometimes contain a claim that, cleaned up, turns out to have evidence behind it.
- Context maximalism — the question itself sets what’s relevant, so the map stays comprehensive without becoming everything-about-everything.
- Separating information from identity — “if you have an opinion, it has you.” Treating ideas as objects you can pick up, examine, and put down, rather than parts of yourself to defend.
- No imposed weights — the library puts claims in context (pro, con, provenance) but doesn’t score them; it leaves the structured data for different communities to weigh by their own values.
Presentation isn’t only trees, which most people won’t read. Society Library Papers are interactive documents you can unpack from a one-page summary down to the evidence behind any single sentence.
Politicians as “outdated technology”
Section titled “Politicians as “outdated technology””Joyce’s sharper provocation: a representative performs two functions a database could augment — representation (holding a population’s preferences and arguments) and deliberation (weighing them through structured argument). A database can hold and audit a community’s stated views more faithfully than the “black box” of one person’s memory; an argument map pre-organises the reasoning a legislature is meant to do anyway. Not to replace politicians, she stresses, but to give them a far richer, auditable basis for decisions.
The catch is the one that haunts all civic tech: adoption. When the Society Library built a micro-voting model for a tense city-council dispute (at-large vs single-member districts), making each member go on record argument-by-argument before their vote aggregated, the activists felt heard and some council members loved the clarity — but others refused to participate, precisely because it would put them on record with what they actually believed.
Why preserving the record matters
Section titled “Why preserving the record matters”Joyce also worked at the Internet Archive on Democracy’s Library, Brewster Kahle’s initiative to collect the world’s government documents in one place. Government records — federated, often undigitised, sitting in boxes in basements — turn out to be the richest substrate for these maps, because adjudicating a live question (is the plant seismically safe?) often depends on documentation going back decades.
Argument mapping is a cousin of Polis-style opinion-mapping and uncommon ground: all three resist collapsing a debate to a single number, and instead make its real shape legible. See also the epistemic case for democracy.
