Describe model-dependent realism.
Question
Describe model-dependent realism.
Solution
Model-dependent realism is a view of scientific inquiry that focuses on the role of scientific models of phenomena. It claims that a model is a good model if it:
- Is elegant
- Contains few arbitrary or adjustable elements
- Agrees with and explains all existing observations
- Makes detailed predictions about future observations that can disprove or confirm the model if they are not met.
According to this view, it is pointless to ask whether a model is real, only whether it is an effective tool in predicting phenomena. If there are different models that all correctly predict the same phenomena, there is no "real" one among them: we can use whichever model is most convenient.
This concept is heavily used in the interpretation of quantum mechanics, where different models that describe the same observations (like the Copenhagen interpretation and the many-worlds interpretation) are all considered equally valid.
