The lesson should be trust science, and trust an expert only when he or she is speaking directly from knowledge of the relevant science. Unfortunately, not all areas of human endeavor are amenable to the scientific method. Economics is an edge case; there seems to be at least as much quackery as solid science among economists. Forensics could be much more scientific but is held back by poor incentives. Spycraft or “intelligence” is almost like forensics writ large, and I suspect it will always be dominated by intuition and emotion, even when using mass surveillance techniques.
