Models
There is no guarantee that ideas based solely on a model are correct.
Item MO095001: A model can predict the behavior of the object it represents (e.g., a car crashing into a wall), but the predicted behavior of the object may not be exactly the same as the actual behavior of the object because a model is never exactly the same as the object it represents.
Can a model of an object (such as a car) be used to predict how an object will behave in certain situations (such as crashing into a wall)?
- No, a model is only useful for communicating to others what an object is like, not for making predictions about how an object will behave.
- 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.
