Better Be Paranoid to Survive
Here we enter the territory of our hunter gatherer ancestors in the savannah. It must have been rather scary, out there in the open, exposed to the elements, in the presence of creeping spiders, crawling scorpions, and slithering snakes, not to mention a host of other wild creatures inspiring fear and generating risk. Like the rabbit in the life dinner principle, our ancestors had to fight to survive. Maybe they were better off being a little paranoid. So meet the paranoid optimist!
