Helmut, List, Measures of dispersion, entropy, indeterminacy, uncertainty, whatever we choose to call them are abstract mathematical thingies that can be defined in a wide variety of settings. Whether any piece of mathematics has utility in a given setting is one of those “proof of the pudding lies in the eating” (POTPLITE) sorts of issues. In other words, useful is as useful does.
It's always worth exploring potential analogies between applications but there is no metaphysical necessity about a given measure having utility in a given domain nor any guarantee that it's usefulness will transfer to another domain.
