Unfortunately I have seen or heard of no evidence about the causality of this willingness to be a hero - or otherwise. Nothing to indicate that the education levels, or parental guidance, or peer group advice, or social standing, or how much one has to lose from it, are more or less likely to lead to the heroic decision when the time comes.

And I've seen in my own lifetime plenty of evidence to support the belief that humanity is only skin-deep in the vast majority.

Like all of us, I hope that when the test comes, I will prove equal to it; but the statistics are stacked against me.

All we can do meanwhile is just pray that we won't have to be so tested, and meanwhile try to be understanding and fogiving, if not accepting, of those that fail theirs.
