That's not really fair, we as humans are bad at risk analysis. Bruce Schneier has written extensively on the role of cognitive biases et al in measuring perceived risk.
I've been looking for years for a good reference that says "human are bad at probability estimation", but this one doesn't seem to work: he's simply saying that we're very good at estimating regular risks (if I understand correctly).

Googling "Schneier risk" gets you lots and lots of reading material.
The only question here is whether Arrington is going to write another Amateur Hour post about this.
