I’m filing this article away in a category that I’m trying to understand: why and when are people irrationally afraid of invisible threats?

People are petrified of nuclear power and radiation. In California, people were freaking out that radiation from a Nuclear power plant 5,000 miles away in Japan would leak into the water, infect fish, and then radiate US consumers.

Meanwhile, Russians hacked our social networks and corporations are injecting addictive additives to our foods.

And I’m just really fascinated by the psychology of the response. Why is there sometimes too much fear and other times too little?
