Existing research on negations primarily focuses on entropy and extropy. Recently, new functions such as varentropy and varextropy have been developed, which can be considered as extensions of entropy and extropy. However, the impact of negation on these extended measures, particularly varentropy and varextropy, has not been extensively explored. To address this gap, this paper investigates the effect of negation on Shannon entropy, varentropy, and varextropy. We explore how the negation of a probability distribution influences these measures, showing that the negated distribution consistently leads to higher values of Shannon entropy, varentropy, and varextropy compared to the original distribution. Additionally, we prove that the negation of a probability distribution maximizes these measures during the process. The paper provides theoretical proofs and a detailed analysis of the behaviour of these measures, contributing to a better understanding of the interplay between probability distributions, negation, and information-theoretic quantities.
