I thought about it and couldn't figure out why it's obvious. Care to share some light on that?
Not saying it’s the best joke, just explaining the meaning.
(and really, much of the time, acceptance is the wrong word. Indifference or something like that often fits better)
Correlated implies a statistical relationship, ruling out phrases like "will take any risk regardless" and requiring phrases more like "may tend to" and such.
And then I even said that I "expect" the correlation, so it's probably reasonable to read the usage as more conversational than scientific.
