Let $P = (\Omega, \mathcal{F}, \mathbb{P})$ be a D1159: Probability space such that

(i)	$(a, b) \subseteq [-\infty, \infty]$ is an D5146: Open basic interval
(ii)	$X : \Omega \to (a, b)$ is a D3161: Random real number on $P$
(iii)	\begin{equation} \mathbb{E} |X| < \infty \end{equation}

Let $\varphi : (a, b) \to \mathbb{R}$ be a D5606: Subconvex real function.

Then \begin{equation} \varphi(\mathbb{E} X) \leq \mathbb{E} \varphi(X) \end{equation}
