AI偶尔犯错,为什么接入自动化后会变成大问题? / Why Does an Occasional AI Error Become Serious Under Automation?

Judgment in the Age of AI · Article 41

In manual use, one wrong answer usually affects one decision. Under automation, the same mistake can reach thousands of objects within minutes. Risk is not merely the error rate; it also includes speed, scale, authority and detection delay.

Estimate blast radius with four multipliers

Impact ≈ consequence per action × volume × executable authority × time before detection

A small loss per event can become substantial when volume is large and nobody notices for a long time. Conversely, a small number of high-consequence actions still calls for strong confirmation.

Put fuses into the system

Fuse Purpose
Rate and value limits Cap the reach of one abnormal run
Sample review Find a pattern before every case is affected
Anomaly threshold Pause when distributions, reversals or complaints change sharply
Gradual release Validate in a small population first
Kill switch and rollback Restore a known state quickly

Before automating, write down how much the worst single run could do. A system whose reach cannot be measured, stopped or reversed is not ready to operate unattended.
