While we hear about Bayes' Theorem being under threat in some courts, it is nice to savor the occasional moment of rationality prevailing in the justice system, and of mistakes being corrected.
Congratulations to the Italian court system for successfully saying "Oops!"
Things go wrong in this world quite a bit, as we know. Sometimes it's appropriate to just say "hooray!" when they go right.
Discuss, or celebrate.
One of the most interesting and tragic things about this is how Kercher's family has reacted very negatively. See e.g. this article.
This is an understandable reaction on their part. They've become convinced that Knox killed their daughter and tried to cover it up. The amount of emotion and feelings of identity that must get wrapped up in trying to make sure that the killer of one's child is convicted and jailed must be massive. The cognitive difficulty in acknowledging that one has gone after the wrong person must be immense. If I were (Omega forbid) in a similar situation, I suspect that I'd react very similarly to the Kercher family.
So, what might we do -- as in what cognitive strategies should we employ -- to prevent falling into such a trap?
