This, I think, is just one symptom of a more general problem with scientists: they don't emphasize rigorous logic as much as they should. Science, after all, is not only about (a) observation but about (b) making logical inferences from observation. Scientists need to take (b) far more seriously (not that all don't, but many do not). You've heard the old saying "Scientists make poor philosophers." It's true (or at least, true more often than it should be). That has to change. Scientists ought to be amongst the best philosophers in the world, precisely because they ought to be masters of logic.
