✳️ " All models are wrong, some are useful "
▶️ “A model is a simplification or approximation of reality and hence will not reflect all of reality … While a model can never be “truth,” a model might be ranked from very useful, to useful, to somewhat useful to, finally, essentially useless.”
- Ken Burnham and David Anderson
▶️ “A model which took account of all the variation of reality would be of no more use than a map at the scale of one to one.”
- Joan Robinson
▶️ “The world doesn’t have the luxury of waiting for complete answers before it takes action.”
— Daniel Gilbert
▶️ “Scientists generally agree that no theory is 100 percent correct. Thus, the real test of knowledge is not truth, but utility. Science gives us power. The more useful that power, the better the science.”
— Yuval Noah Harari
