Non-political Use
Outside of politics the use of the term is not as pejorative. A scientist or mathematician can often obtain some experimental results or logical proofs which causes one to flip flop on a previously held belief. Example: "I always assumed that there was an infinity, that all infinite numbers were equal, but I have flip flopped on that since I saw Georg Cantor's proof." Lewis Eigen, in his essay on the cultural difference between politics and scientists, observes, "To the scientist, failure to flip-flop in the face of contradictory evidence is irrational and dangerous behavior. And scientists will often flip-flop at almost light speed. Often it takes only a single observation to flip-flop thousands of scientifically learned people." In the scientific field a flip flop is generally positive as it indicates new learnings and breakthroughs.
