President of the industry advocacy group American Council on Science and Health Hank Campbell and microbiologist Alex Berezow have described "feel-good fallacies" used in politics, where politicians frame their positions in a way that makes people feel good about supporting certain policies even when scientific evidence shows there is no need to worry or there is no need for dramatic change on current programs. They have claimed that progressives have had these kinds of issues with policies involving genetically modified foods, vaccination, overpopulation, use of animals in research, nuclear energy, and other topics.
