Is there a difference between falsification and refutation? Popper used the former in the book about logic of scientific discovery and the latter in the last (conjecture and refutation). And I never understood the difference.

It can be interesting to read why so many psychological scientists have raised concerns - which twice led to a crisis - about (social) psychology for over half a century. There are important lessons we can learn from our history about why these concerns have not been solved.

This is, in large part, pandemic revenge. As far as these oligarchs are concerned, all science does is tell them stuff they cannot do. They can't keep spewing carbon. They can't keep businesses open as usual when millions are dying. They have concluded that research is the enemy of profit.
