Science Isn't Perfect. But it Works Better than Most Systems

Scott Alexander:
Scientific consensus hasn’t just been accurate, it’s been unreasonably accurate. Humans are fallible beings. They are not known for their ability the change their mind, to willingly accept new information, or to put truth-seeking above political squabbles. And our modern society is not exactly known for being an apolitical philosopher-kingdom with strong truth-seeking institutions completely immune from partisan pressure. I feel a deep temptation to sympathize with global warming denialists who worry that the climatological consensus is biased politicized crap, because that is exactly the sort of thing which I would expect to come out of our biased politicized crappy society. Yet again and again I have seen examples of scientific fields that have maintained strong commitments to the truth in the face of pressure that would shatter any lesser institution. I’ve seen fields where people believe incredibly-bizarre sounding things that will get them mocked at cocktail parties just because those things seem to be backed by the majority of the evidence. I’ve even seen people change their minds, in spite of all the incentives to the contrary. I can’t explain this. The idea that scientific consensus is almost always an accurate reflection of the best knowledge we have at the time seems even more flabbergasting than any particular idea that scientists might or might not believe. But it seems to be true.

The trick is to know who is talking, the science or the scientist.
