Why Do People Fear G.M.O.’s?

Genetically modified food (or G.M.O.'s) continue to provoke heated debates about safety and labeling, even though scientific evidence indicates they're safe.  Why?  A new article in Cosmos by David Ropeik explores the psychology behind people's G.M.O. fears. Here is Ropeik on why man-made risks "feel" scarier than natural risks.

Beyond those heuristics, several specific emotional characteristics also make G.M.O.'s feel scary.
