Would you rather we don't have these numbers help us with decision making? Do you have a better system in mind? Should we just never discuss or think about risk/reward trade-offs as soon as it involves a single life at risk?

I also don't get where the Wikipedia snark is coming from. I know that Wikipedia pages are not perfect but It's still a pretty good reference for a lot of things. I often trust Wikipedia articles for any given subject as long as it is well-sourced and not political just like this one.
