The line worker has a canny instinct for the right answer long before the statistics are significant though.
Kinda what Gladwell talks about in Blink
In my experience, the line worker's instincts are to be trusted but verified. If we blindly follow every crisis from the line we'd quickly find ourselves in a pit. These crises need to be backed up with context and a sense of criticality as there are finite resources to work through problems, and solving one person's immediate problem on the line may have a crushing impact elsewhere.
Sometimes, but a few times those instincts are very very wrong. Blink is interesting, be sure to read the criticism though https://en.wikipedia.org/wiki/Blink:_The_Power_of_Thinking_W... - it isn't clear that the book is correct.
