Forum Post Cruxes and Pivotal Questions Explorer

What this is

A curated, structured record of EA Forum and LessWrong posts containing explicit cruxes, "what would change my mind" statements, action-relevant uncertainties, and Pivotal Question-adjacent formulations. Compiled from a deep research scan of posts published April 2023 – April 2026. The core dataset covers April 2024 – April 2026; entries from April 2023 – April 2024 are marked as year-expansion additions.

Schema fields

• Signal type — how explicitly the post frames its uncertainty (explicit crux, hinge belief, CMM, research question…)
• Crux / change condition — what belief is load-bearing; what would change the author's view
• Why it matters — why this entry is Unjournal-relevant
• PQ mapping — candidate Pivotal Question formulation where applicable
• UJ relevance — Very high → Low, based on tractability for evaluation or synthesis
• Tier — Shortlist = highest priority for Unjournal action; Longlist = worth tracking

Update cadence

The site is redeployed automatically every Monday and Thursday as part of The Unjournal's research-prioritization pipeline. However, the cruxes dataset itself is manually curated — new entries are added by human review, not by the automated scraper. The dataset grows through community contributions and periodic curation sprints.

How to contribute

Use "Suggest entry" to open a GitHub Issue with the post URL and why you think it qualifies. Corrections, reclassifications, and better PQ mappings are all welcome. You can also annotate entries directly using the Hypothes.is sidebar (top-right button) — annotations are public and visible to maintainers. See the repo for the full update workflow.
