What traditional belief exists about human performance?

• A. That it is a worker-focused phenomenon
• B. That it is primarily caused by equipment failure
• C. That it is a management issue
• D. That it is solely driven by weather

Answer: (A)

The traditional belief about human performance is that it is a worker-focused phenomenon—the idea that performance problems come from the individual on the job, with the primary remedies being training, instruction, and personal accountability. This view treats the worker as the main cause of mistakes, so safety efforts historically aimed to improve the worker’s skills and discipline rather than altering the work system. Yet modern understanding shows performance is shaped by many system factors—equipment design, procedures, supervision, workload, fatigue, environment, and organizational culture—so blaming the worker alone is incomplete. The other options point to equipment, management, or weather as the root cause, which can influence outcomes but don’t reflect the traditional emphasis on the worker as the central source of performance issues.
