I saw a theory somewhere that human beings aren't very good at intuitively understanding even large order of magnitude differences between unlikely events. We have a mental category of "unlikely but not impossible" and slot everything from one in a thousand to one in a billion into that bucket.

I.e. the Lloyd Christmas bucket (Dumb and Dumber). "You mean, not good like one out of a hundred?" "More like one in a million." "So you're telling me there's a chance!"
