There is no guarantee that ideas based solely on a model are correct.
Item MO070004: A model of an object can be used to predict how an object will behave, but the prediction may not be the same as the actual behavior of the object because a model is never exactly like the object it represents.
Can a model of an object be used to predict how an object will behave?
- No, a model is only useful for communicating to others what an object is like, not for making predictions about an object.
- No, predictions made with a model are never useful because a model is never exactly the same as the object it represents.
- Yes, a model will behave exactly as the object it is representing behaves because a model is exactly the same as the object it represents.
- Yes, but the predicted behavior of the object may not be the same as the actual behavior of the object because a model is never exactly the same as the object it represents.
