Proximate and ultimate causation
Event which is closest to, or immediately responsible for causing, some observed result
A proximate cause is an event which is closer to (more immediately responsible for) causing some observed result. This exists in contrast to a higher-level ultimate (or distal) cause, which acts less directly through the proximate cause. In formal causal inference, the proximate cause is called a mediator.
Example: Why did the ship sink?
Proximate cause: Because it was holed beneath the waterline, water entered the hull and the ship became denser than the water which supported it, so it could not stay afloat.
Ultimate cause: Because the ship hit a rock which tore open the hole in the ship's hull.
In most situations, an ultimate cause may itself be a proximate cause in comparison to a further ultimate cause. Hence we can continue the above example as follows:
Example: Why did the ship hit the rock?
Proximate cause: Because the ship failed to change course to avoid it.
Ultimate cause: Because the ship was under autopilot and the autopilot's data was inaccurate.
This brief starts where responsible research should: with the source description of “Proximate and ultimate causation” as event which is closest to, or immediately responsible for causing, some observed result. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as event which is closest to, or immediately responsible for causing, some observed result. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated May 12, 2026. The linked authority identifier is Q7252855. None of the 0 selected statements returned an explicit reference.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
- Event chronology
- Institutional context
- Locating named record creators
Contemporary correspondence, government or organizational records, oral histories and cited historical scholarship.
Three-step research path
- Establish the record: confirm the title “Proximate and ultimate causation”, its source revision and the description used here.
- Expand the search: follow Proximate and ultimate causation primary sources, Proximate and ultimate causation archive and Proximate research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
- Which source most directly establishes the central claim about “Proximate and ultimate causation”?
- Which voices are present, absent or mediated by the institution?
- Who created the surviving record, and for what administrative purpose?
