Distinguish system causes from individual causes in the analysis
Most failures have system causes and individual causes; fixing only the individual leaves the system to produce the same result again.
Key takeaways
- What it is: Most failures have system causes and individual causes; fixing only the individual leaves the system to produce the same result again.
- Why it works: Attribution research shows humans default to personal attribution ("I made a mistake") over situational attribution ("the system made this mistake easy to make"), especially in self-analysis. System causes — ambiguous processes, missing information, misaligned incentives — tend to recur until addressed structurally. Individual-level fixes on system problems produce temporary improvement followed by relapse.
- Evidence: Established clinical or therapeutic practice.
- Avoid: Resolving the same gap with the same individual-level fix repeatedly without asking whether the system is reliably producing the gap despite individual effort.
Why it works
Attribution research shows humans default to personal attribution ("I made a mistake") over situational attribution ("the system made this mistake easy to make"), especially in self-analysis. System causes — ambiguous processes, missing information, misaligned incentives — tend to recur until addressed structurally. Individual-level fixes on system problems produce temporary improvement followed by relapse.
How to do it
- 1In the causal analysis, ask both: "What did I do that contributed?" and "What about the situation or system made this outcome more likely?"
- 2For recurring gap patterns across multiple AARs, specifically look for the system cause rather than applying the individual fix again.
- 3Implement system changes (checklists, process modifications, environment redesigns) when a pattern repeats more than twice.
What the evidence says
Clinical practiceHuman factors and safety research consistently finds that system-level contributing factors are underweighted in post-event analyses, and that individual-blame responses leave error-producing systems intact.
Honest caveat: Safety engineering research focuses on high-consequence domains; the system-vs-individual attribution principle generalises to personal productivity and performance, but the stakes and stakes-structure differ.

Common mistake
Resolving the same gap with the same individual-level fix repeatedly without asking whether the system is reliably producing the gap despite individual effort.
IX Coach tracks repeated gap patterns across your AAR history and surfaces the system-level question when the same individual fix has been applied multiple times without durable change.
