Risk-Risk Trade-off / 风险—风险权衡

Definition

Risk-risk trade-off is a systems condition in which an intervention that lowers one danger simultaneously raises another, so the decision requires comparison across failure modes rather than a claim that safety has simply increased.

Current Synthesis

The episode illustrates the mechanism through aviation. A reinforced cockpit door limits hostile entry but can obstruct rescue or intervention when the threat is already inside. Stricter pilot-health review can surface impairment but can also make disclosure costly enough that some workers hide symptoms or avoid care. The common mechanism is not that protection is futile; it is that barriers and screening redistribute access, information, and incentives.

This concept is distinct from Safety Tradeoff Blindness. Risk-risk trade-off describes the underlying substitution even when decision-makers recognize it, while trade-off blindness describes failure to compare the new harms created by a visible safety objective.

Key Claims

• Safety interventions can redistribute risk rather than eliminate it.
• A barrier that blocks an external threat may also block help when the threat originates inside the protected boundary.
• Screening can improve detection while reducing candor when disclosure carries employment, income, or certification costs.
• More resources do not automatically dissolve a structural conflict between access control, privacy, intervention, and truthful reporting.
• Responsible governance compares likelihood, severity, reversibility, incentives, and mitigation across all material failure modes.

Evidence

Access-control reversal

• 总第073期：正是那令我安心的，让我感到不安 uses reinforced cockpit doors to show how protection against external intrusion can impede intervention against an insider threat.

Disclosure incentive

• 总第073期：正是那令我安心的，让我感到不安 argues that complex medical certification and career consequences can make pilots less willing to disclose health concerns even when screening is intended to improve safety.

Cross-domain mechanism

• 总第073期：正是那令我安心的，让我感到不安 explicitly generalizes the trade-off beyond aviation to medicine, public health, and ordinary life choices.

Counterevidence & Qualifications

The source does not provide a quantified comparison of the risks, prove that reinforced doors or medical certification produce net harm, or establish a preferred aviation policy. Some trade-offs can be reduced through redundant staffing, reporting protection, confidential care, monitoring, emergency access, or better implementation even when they cannot be eliminated. The cited flight events, survey result, and institutional details remain episode-attributed pending primary evidence.

What Changed

• Created a neutral systems concept separating risk substitution from blanket opposition to safety measures.
• Distinguished the mechanism from institutional blindness to secondary harm.
• Added access-control and disclosure-incentive pathways.

Related Concepts

• Safety Tradeoff Blindness - governance failure that occurs when decision-makers ignore the secondary risk identified here.
• Safety As Control - adjacent case where safety rules can become mechanisms of authority and restriction.
• Bureaucratic Risk Avoidance - explains why institutions may optimize the most visible accountable risk.
• 喜恶同因 / Same-Cause Attraction and Aversion - broader frame for benefits and costs generated by the same arrangement.
• Work-Rest Boundary / 工作休假边界 - everyday domain where security, freedom, workload, and stopping authority interact.
