The story is that the administration has been systematically destroying the federal government's scientific resources, and purging scientific expertise and even generally known facts from the decision making process. To quote the Times story:
In just three years, the Trump administration has diminished the role of science in federal policymaking while halting or disrupting research projects nationwide, marking a transformation of the federal government whose effects, experts said, could reverberate for years. Political appointees have shut down government studies, reduced the influence of scientists over regulatory decisions and in some cases pressured researchers not to speak publicly. The administration has particularly challenged scientific findings related to the environment and public health opposed by industries such as oil drilling and coal mining. It has also impeded research around human-caused climate change, which President Donald Trump has dismissed despite a global scientific consensus.I've discussed some of this before, in this space. The reason this is happening is simple, as Stephen Colbert has explained: Reality has a well-known liberal bias. If we believe that ultrafine particle pollution kills people, that toxins in the water supply sicken and kill people, then we would have to conclude that the Free Market™ does not magically make the world wonderful. We would have to draw the same conclusion if burning fossil fuels causes destructive climate change. If we were to believe those Chinese hoaxes, then billionaires would not be free to enrich themselves by poisoning us and destroying civilization. That would be a violation of the sacrality of the Free Market™, so none of it can possibly be true.
And those scientists must all be commies.
Well, if you voted for him, you must agree with all that. Too bad about all those hundreds of years of scientific progress since The Enlightenment. Obviously that was all a hoax. Things were so much better in the 14th Century.
