If correlated, it should be that religiosity, and belief in protection of a supposed omnipotent & omniscient being, will allow one to be less risk averse.
Also, that more risks could be taken, given that death permits access to the supposed heaven, a sought after destination.

I've never understood their objection to abortion (fast tracking to heaven without possibility of sin), or euthanasia (quick visit with priest for penitence, then off to heaven; bypassing the pain extended scenic route).

Not sure risk aversion is related to religion at all. Seems like a simple personality trait. Not everything in life is tied to religious beliefs.

I think it depends on the culture of the specific risk. My husband was an atheist and he rode bulls in his youth. I would say 95% of bull riders think they are religious. Note I said think they are religious.

More expensive risk taking sports and activities are probably 70% believers and 30% non-believers like the rest of the population.

It’s all bullshit.

One study from among several:

"First, we find strong confirmatory evidence that more religious people, as measured by church membership or attendance, are more risk averse with regard to financial risks.

"Second, we obtain some evidence that Protestants are more risk averse than Catholics in such tasks.

"Third, our data suggest that the link between risk aversion and religion is driven by social aspects of church membership, rather than by religious beliefs themselves."

Here's another - I never knew there was a Journal for the Scientific Study of Religion

There doesn’t seem to be a great deal of difference. I’d like the honesty humility experiment to be redone as find the results difficult to believe:

I have two friends who are married to guy's who are not only religious but they cheat on them all the time. They believe they're basically forgiven by God every time they do it. These friends of mine have very low self-esteem and think they have some kind of prize by being married to these pieces of shit. I don't know what to think, just they're all really stupid.

How the religious person view his religious belief and values determines how risk-averse he or she is. If he or she views those beliefs and values as :ceiling values"(placing limits on what one -- the "shalt nots" -- on what one can do and say make some religious people risk averse. If the religious person sees his or her religious beliefs and values as "floor values" (values and beliefs which provide a basis from which t grow) that tends to give the person the sense of strength to take risks.
