Habits Quote by Donella H. Meadows
““Model utility depends not on whether its driving scenarios are realistic (since no one can know that for sure), but on whether it responds with a realistic pattern of behavior.””
About This Quote
Source Article: The Limits to Growth, 1972
A model’s value lies in producing realistic behavior, not in matching exact real‑world scenarios, because true realism is unknowable.
In simple terms: Models work if they act like reality, not if they copy it perfectly.
Key Takeaway
Focus on realistic behavior, not perfect scenario matching.
