The first principle is that you must not fool yourself and you are the easiest person to fool.
Richard P. Feynman
Last Monday in Los Alamos, I attended a lecture about black holes and gravity waves given by Nobel laureate Kip Thorne. He detailed the long history of this research going back to Einstein and Oppenheimer. As he described it, they were extremely careful about interpreting LIGO gravity wave measurements, and when they first detected one (after 20 years of searching) they were very skeptical, and even suspected someone had hacked the data as a prank.
Compare vs. climate science, where they intentionally hack their own data to achieve the results they want.
