- Overview of chapter in forthcoming
Incremental Safety Practices book. An
early large-scale empirical analysis of incremental safety was undertaken,
assessing pilots' performance after obtaining access to personal data. A change in behavior was observed, yet
epistemic and philosophical issues arise from what 'incremental safety'
practically means.
- Discussion of the rapid advances in
technology that allow the worker, versus the organization, to identify
acceptable outcomes and nominal performance.
What are the consequences for incremental safety when workers self-diagnose
and change behavior, versus an organizational approach?
Discussion that 'normal work'
constitutes the 'dark matter' of safety science: it exerts gravitational
influence, yet has been mostly invisible to measurement. Personal flight data represents the first
instrument capable of illuminating this dark matter. Applying science
philosopher Hasok Chang's framework to incremental safety (Chang, 2004),
measurement systems and concepts co-evolve, and we must therefore develop the
theoretical vocabulary for what normal performance actually is.
