A feature of scoped entropy [1] analogous to mutual information is the following:

For any random variable \(X\) and random object \(Y\) of finitely many values, \[ \begin{array}{lcr} \operatorname{V}_{ \mathfrak{d}(X)}(Y) = 0 & \text{ if and only if } & \mbox{ $X$ and $Y$ are independent} \end{array} \]
