 Dec 4 answered Signal processing : future values prediction Nov 19 comment Inequality for conditional expectation Amazing answer, thank you! This is a very nice explanation why conditional independence implies the inequality. I leave the question open because the other interesting case is what happens if $X$ and $Y,\Theta$ are not conditionally independent, in which case there should also be conditions where the inequality holds.

Sep 29 comment Inequality for conditional expectation I mean if the conditional cdf $F(\theta|X=x,Y=y)$ dominates the conditional distribution $F(\theta|X=x,Y=y')$ for any $y'>y$, then the conditional expectations of $g(\theta)$ will differ for $Y=y$ and $Y=y'$ for any strictly increasing $g(.)$.
