All models are wrong, but some are useful.
This is a reference to mathematical models.
Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.
Alternative models are neither right nor wrong, just more or less useful in allowing us to operate in the world and discover more and better options for solving problems.
All models have faults - that doesn't mean you can't use them as tools for making decisions.
All models are approximations. Essentially, all models are wrong, but some are useful. However, the approximate nature of the model must always be borne in mind.
The purpose of science is not to analyze or describe but to make useful models of the world. A model is useful if it allows us to get use out of it.
All models are false but some models are useful
