The higher you rise in any hierarchy, the harder it is to get accurate feedback about your decisions because people are afraid to tell you the truth. I’ve worked with several (US) presidents. All have made big blunders. I’ve also known and written about CEOs of big corporations who have made terrible mistakes. In every case, they had flawed systems for getting useful, accurate and reliable feedback.Robert Reich (some kind of former political appointee from the USA) https://www.theguardian.com/commentisfree/2022/apr/01/vladimir-putin-ukraine-truth-deniers-bad-decisions
There seems to be a lot of confusion about the role of trust in science or scholarship. Engineers such as Bill Nye and political propagandists throw around the phrase “trust the science”! On the other hand, the rationalists whom I mentioned last year brandish the Royal Society’s motto nullius in verba “Take nobody’s word for it” like a sword. I think both sides are working from some misconceptions about how science or scholarship work.
Lets say I want to back a claim with a passage in Herodotus. I probably start by reading a translation. If the details are important, I can check a Greek text. How do I know that someone did not make up the Greek? The Greek text has a critical apparatus showing any significant differences between the printed text and the manuscripts. That text was printed by someone who I never met and may have died before I was born. The scholar who created it worked with the manuscripts, and when it was done it was reviewed by other people who had seen the manuscripts and could compare other printed editions. I can’t read abbreviated Byzantine handwriting, and I have not tracked down all of these manuscripts or read them closely to know which seem to be closest. I can’t look at one of those manuscripts and say when it was written. But I can bring science forward by leaning on the networks of trust and suspicion which produced those critical editions. And the people who created those editions could not move science forward in the areas I write about.
I don’t need to trust some sacred text or wise teacher to know what Herodotus said. I could in principle trace any claim about what he said to the manuscripts and to a detailed study of the Greek language which left no commonplace unchallenged. But in practice, I (and most other people interested in the ancient world) very rarely do so. What makes this scientific or scholarly is not that you do every step yourself. It is that every step of the argument has been checked by multiple independent people, so in most cases you can quickly see if those people disagree and then trust those preliminary steps. Science or scholarship is not about heroes who know every skill, its about systems of questioning and verification which let us provisionally assume that some things are true while we focus on something where we are not sure of the answer. As humanity’s body of knowledge increases, we have to rely more and more on these systems of questioning and verification. This is more powerful than those super-scholars, because different types of people with different strengths can focus on different parts of the problem. I would be bored stiff comparing manuscripts and the development of the Greek language and Greek handwriting to guess how what Herodotus wrote might be different from what any of the manuscripts say. But some people love that! I am not a metallurgist, but I can learn from metallurgists who have examined ancient iron (just like they rely on archaeologists and conservators to excavate that iron, to clean it, and to assign it to a period and a culture).
The rationalists have an idea that a virtuous thinker should be prepared to engage with and independently evaluate any claim, however strange and however far from their expertise. This sounds rather adolescent to me, like the spotty teenager who demanded that a MMA star fight him. Its not “an impressive signal of epistemic virtue” to approach every claim someone makes with an open mind. That is a way to get tricked into believing nonsense and supporting horrible acts (or at least to be tricked into spending vast amounts of time and work carefully evaluating claims which were created by quick and lazy methods). The prudent person carefully balances asking “who should I trust?” on most topics, and asking “what does the evidence best support?” on a few carefully chosen topics. As long as some people ask about evidence and pass on their results, society as a whole can gain new knowledge. Its like how we can shop without worrying that some of the peppercorns are random seeds painted black, or go to a bar trusting that the glasses are the size they say they are, the drinks have not been watered down, and that the active ingredient is alcohol not methanol. Our society has people and institutions which verify that grocers and publicans are selling what they claim to sell, and these people and institutions are so effective that the rest of us we can forget they exist.
In my next post on this topic, I will talk about deciding who to trust and when this system can break down.
