Evidence for Others’ Mistakes #
Every substantive claim on the Others’ Mistakes page is checked against current research. Here is each claim, how well today’s evidence supports it, and the sources. The full, de-duplicated source list lives on the references page.
Supported · strong evidence — Today’s aviation safety record is a result of learning from the mistakes of others through accident investigations; studying others’ mistakes can improve your competence in your own field.
Industry data confirm a sustained, large long-run decline in fatal-accident rates, and the industry explicitly attributes this to safety data and learning from investigation findings. Supports the page’s central premise.

Supported · moderate evidence — Today’s aviation safety record is a result of learning from the mistakes of others through accident investigations; studying others’ mistakes can improve your competence in your own field.
Quantifies the dramatic decline (40 to ~0.1 fatal accidents per million departures) and ties it to more effective accident investigation. Secondary/industry source rather than peer-reviewed, hence moderate.
Supported · strong evidence — A passenger aircraft crashed into a Florida swamp in December 1972; the flight crew was focused on a faulty undercarriage (landing gear) light, everyone thought the plane was on autopilot, and nobody noticed the aircraft descend into the swamp.
The event, date (29 Dec 1972), the burned-out nose-gear indicator bulb, and the fatal preoccupation/distraction are all correct and match the NTSB finding. The page’s core lesson is exactly the documented cause.

Mixed · strong evidence — A passenger aircraft crashed into a Florida swamp in December 1972; the flight crew was focused on a faulty undercarriage (landing gear) light, everyone thought the plane was on autopilot, and nobody noticed the aircraft descend into the swamp.
Two minor inaccuracies in the page: there were four occupants in the cockpit (not ’three’), and the autopilot had effectively dropped out of altitude-hold rather than the crew merely assuming it was ‘on’. The substantive lesson (fixation on a minor fault while the plane descended) is faithful to the record.

Supported · moderate evidence — Fixating on one issue for an extended period while neglecting the bigger picture is dangerous (the implicit human-factors lesson of the example).
Attentional tunneling / cognitive fixation is a well-established human-factors phenomenon directly matching the page’s lesson, and recent (2024) studies continue to demonstrate it in pilots. Moderate because the page makes a general qualitative point rather than a quantitative one.

Supported · moderate evidence — Reading/studying the mistakes others have made (vicarious error learning) is an effective way to learn, improve your own competence, and avoid similar mistakes.
Meta-analytic and review evidence supports learning from others’ errors (erroneous/worked examples), validating the page’s premise in instructional settings. Effects are positive but context- and design-dependent rather than universally large.

Mixed · moderate evidence — Reading/studying the mistakes others have made (vicarious error learning) is an effective way to learn, improve your own competence, and avoid similar mistakes.
Qualifies the claim: learning from errors is real but conditional on supportive framing/reflection, and the benefit of one specific technique (deliberate erring) is contested in recent replications. The page’s general advice (reflect on others’ mistakes and add safeguards) aligns with the supported side.
