Earlier quoted context omitted.
The Soul of a New Machine has an amazing passage on a software developer from Data General being too inexperienced to realize that what he was doing couldn't be done, and finishing it in record time. It's safe to say that people who aren't aware of or ignore limits put out better work on average than people who don't.
That seems decidedly unsafe to say, but even if you’re right, the second paragraph doesn’t follow from the first. “Everyone generalizes from one example! At least, I do.”
The first was just to share an example. The second paragraph is common knowledge.
