Scientists often complain that people are irrational in their opposition to technologies such as nuclear power and genetically modified (GM) crops. From a statistical perspective, these are very safe, and so (it is argued) people's fear can be explained only by emotion, undergirded by ignorance. Electricity from nuclear power has led to far fewer direct deaths than has coal-fired power, yet many people are afraid of it, and hardly anyone is afraid of coal plants. Similar arguments can be made about GM crops, which studies have shown are generally safe for most people to eat.
