An interesting article
that speculates humans haven't evolved enough to handle modern day security risks and on a whole we're still hard wired to recognize and deal with risks the same way our ancestors did 10's of thousands of years ago. Granted, this article is focused on IT security, and the hypothesis is being proposed by someone who isn't an evolutionary biologist or neuroscientist, but it's still intriguing (and would sure help explain some of things I've seen in the field). For more on risk and the brain, read "Why the Human Brain is a Poor Judge of Risk
" or if you want to really get deep, Google "Daniel Kahneman."
