Politics and Science
It’s never a good idea for science to get mixed up with politics.
The World War II era example is one of the most terrible: Nazis + Eugenics = Race Hygene.
The current Eurozone crisis is, in part, the result of mixing populist politics with economics resulting in the “Austerity Policies”.
Another not so recent example is “Climate Change”. It has been so embroiled in politics that’s hard to trust any research around it.
A new study is out: Climate was HOTTER in Roman, medieval times than now. I’m sure that there will be a lot of people on one side hailing it as proof that realizing unimaginable amounts of toxic chemicals into the atmosphere isn’t a bad thing and people on the other side trying to burry the study and the authors in accusations for no other reason than it’s inconvenient to their view of the world.
No good ever comes out of the politicization of science. The only exception to this rule seems to have been the Cold War era space race that ended with a man walking on the moon.
