Popular opinion masqueraded convincingly as science, and the science itself was hard to grasp. People who spoke as experts lacked credentials, and G.M.O. critics discounted those with credentials as being pawns of biotechnology companies.
A longish article, which I have not yet finished, but which I do wish to share based on the opening paragraphs: "A Lonely Quest for Facts on Genetically Modified Crops."
