> I, personally (for example), would not generally assume neuroticism is associated with risk-aversion. In my experience risk aversion (or tolerance) tends to be completely decoupled from other traits.

I wouldn't even say that risk aversion is a one-dimensional thing.

Anecdata: me and my SO have complementary risk tolerance patterns. She avoids financial/material risks but is happy to put herself in, let's say, interesting social situations, while I, conversely, am able to spend money to the point where I'm "running on fumes"(if I believe there's a good reason to do that), but avoid any situations where I would risk making somebody upset, even if they should be confronted.
