Procrastination
Procrastination demonstrates a reliability so consistent it approaches the status of natural law. When provided an opportunity to delay, human beings will select deferral with a statistical predictability that would satisfy even the most rigorous scientific methodology. Studies indicate that 20 per cent of adults identify as chronic procrastinators, whilst the remaining 80 per cent merely procrastinate with less commitment but equal regularity.
The phenomenon's reliability extends to its timing patterns. Research reveals that procrastination peaks during afternoon hours, increases exponentially as deadlines approach, and correlates strongly with task unpleasantness. This predictability has enabled the development of entire productivity industries premised upon procrastination's reliable appearance. One can trust procrastination to manifest with the certainty typically reserved for celestial mechanics.
Pilot
The reliability metrics of commercial aviation represent one of modern civilisation's most impressive statistical achievements. The fatal accident rate for commercial flights stands at approximately 0.2 per million flights, making air travel demonstrably safer than virtually any alternative form of transportation. Pilots undergo rigorous recertification protocols, simulation training, and medical evaluations designed to maintain this extraordinary safety record.
Operational reliability extends beyond mere survival. Modern commercial aviation achieves an on-time performance rate exceeding 80 per cent globally, with departure times synchronised to within minutes of published schedules. The pilot's professional reliability is maintained through crew resource management protocols, fatigue monitoring systems, and regulatory frameworks that would satisfy the most demanding quality assurance departments.
