(Engineers express the same distinction when talking about the difference between precision and accuracy. “When you’ve got baloney, it doesn’t matter how thin you slice it, it’s still baloney”. Or, “An engineer is someone who multiplies 2 by 2 on a slide rule, gets an answer of 3.9 and approximates to 4”.)
- “Climate change was not a serious concern 50 years ago”. Dr. Meadows argues that the model is nevertheless still valid because, “magically eliminating it would still leave other grave problems”. In other words, climate change is not a root cause; instead it is a symptom of deeper root causes.
