>I'd say that believing experts is more an act of philosophy than an act of science.

Not philosophy. Faith.



view as:

Have you read about the Munchausen Trilemma? https://en.wikipedia.org/wiki/M%C3%BCnchhausen_trilemma

I’ve always found that very boring since it seems obvious to me that logical truths require the axiomatic argument, scientific truths require the regressive argument, and reductionism doesn’t allow for complex supernatural claims to transcend from merely needing axiomatic support to affecting scientific truths.

It feels like one of those things in philosophy that religious people greatly exaggerate the importance of.


Well, no - it's the foundational problem of knowledge/epistemology.

How you choose to "solve" it is up to you.

The solution computer scientists like a lot is coherentism. You pull yourself up by the bootstraps - like we do with self-hosting compilers.

Of course, it's just a conceptual game (like all philosophy). The idea of "prove to me that you know..." seems a bit like "Jump for me... Higher!"


>It feels like one of those things in philosophy that religious people greatly exaggerate the importance of.

Appropriately named then!


I agree that in the modern world, many people may find it somewhat "obvious" (or rather, they have a similar belief intuitively), but I think it's very relevant here: of course doubting science requires some kind of faith. So does believing science. Everything requires faith, we can't actually know anything without faith in something.

(I personally am very aggressively areligious, so "faith" here does not necessarily refer to a spiritual faith.)


I think the difficulty with making an equivalence between “faith” and this type of fundamental epistemic limitation is that no matter how well-intentioned you are, religious people are going to take the soundbyte and claim it’s “proof that science can’t explain everything” which will then be “proof that god is possible” which will then mean oppressing people whose beliefs they don’t like.

We need a much different concept than faith.

Faith means continuing to believe something that is massively contrary to the evidence, to preserve some type of fidelity or loyalty to a previous belief commitment.

I think this is massively different than acknowledging the fundamental deductive limitations of reasoning about epistemic metatruths.


>Faith means continuing to believe something that is massively contrary to the evidence, to preserve some type of fidelity or loyalty to a previous belief commitment.

You've just defined faith in a way that wins your argument, but that is not any kind of consensus definition of faith.


I don’t agree. I’m saying there exists a difference of kind between the act of belief in inferential integrity of experts despite fundamental epistemic limitations of philosophy, and the separate act of continuing to believe something contrary to the evidence.

The ubiquitous notion of religious faith is similar to the second thing, and is not similar to the first thing. It’s not a matter of consensus or definition.


Whatever, I don't have time to become an expert in everything, much less the desire. I choose to focus on my small area (which has changed over time, both because my interests change and because my next job needs me to learn something) and trust the rest.

But isn't this part of the point? Philosophically science is about being interested and studying broad range of topics and areas to judge everything for yourself and make your own conclusions, not trust expert opinions. In my experience, whenever I have to rely on an expert opinion I usually feel bad later when I acquire more knowledge in the area myself, as those opinions are almost always wrong.

How are you informed about the experts' opinions. If it's via the news, then what your are getting is almost surely warped.

This statement doesn't even make sense, where are you acquiring this knowledge if not from experts? Are you out there doing field research and conducting your own scientific experiments on every subject you're interested in?

I'd love to hear a couple examples of which "expert opinions" you've disproven for yourself and where you acquired the supporting evidence.


You are confusing opinions with evidence and facts. Obviously you acquire knowledge by reading papers where people are doing research and experiments and presenting evidence, analytics and all the facts from which you can make your own conclusions.

OK, I don't think that this delineation is actually as black and white as you're making it out to be, given most subjects are complex enough to require nuanced interpretations of data/facts, but I'll give you that in some instances there is a fine line, and there are certain areas where there is a lot of disagreement even amongst experts.

Still, an expert, by definition is just someone that has "comprehensive and authoritative knowledge of a subject." You could argue that as soon as you've acquired enough knowledge on a subject to form an accurate opinion, you have yourself become an expert.

Although I'm guessing when you're referring to "experts" you mean "establishment experts." For example, your average doctor whose spent decades studying medicine as opposed to your online research on how to best treat/prevent a certain ailment (you didn't provide an example so I am just referring a fairly common one). What's the difference between your expertise and theirs? On one hand, they have decades worth of rigorous academic study and personal experience over you, on the other hand, you may have a "fresher" perspective that may be devoid of certain institutional biases. I would just strive to stay humble.


I may have looked more in depth into my condition (though that may imply listening to crackpots) than doctors who despite years of study may not be as in depth as me. There is a lot to the entire human body (which is why doctors refer people to specialists, but they need to choose the right specialist which isn't always easy)

except that papers rarely give all the data these days, or even enough to verify the conclusion

>I'd love to hear a couple examples of which "expert opinions" you've disproven for yourself and where you acquired the supporting evidence.

I have one that's related to nutrition. But what's the point if you don't do it yourself, how will you know if I'm right?


"Philosophically science is about being interested and studying broad range of topics and areas to judge everything for yourself and make your own conclusions, not trust expert opinions."

Not quite. It's observation of the world around you. It doesn't preclude experts' opinions, it takes them into account. Reinventing the wheel isn't the goal of science. The goal is to understand why a circle might be the best shape for rolling and under what circumstances it might not be.

More specific to current times, ignoring the advice of epidemiologists with respect to masks and social distancing is proving to be costly in life and economy.

"In my experience, whenever I have to rely on an expert opinion I usually feel bad later when I acquire more knowledge in the area myself, as those opinions are almost always wrong."

Care to share a specific example from your life?


What you're describing was true in the Renaissance, but it's incredibly, achingly difficult for someone to gain expertise in multiple areas of science in this era.

Faith implies there is no mathematically sound reasoning underlying the belief, at least a little

The hypothesis "Expert consensus is more likely to be correct" is falsifiable and thus not purely blind faith


Unfortunately, the recent reproducibility crisis amongst expert ‘scientists’ has damaged this hypothesis greatly.

>Expert consensus is more likely to be correct" is falsifiable

That's one of those things that sounds like it should be falsifiable, but in practice it's not. The statement is far too broad to conduct reasonable experiments, and if you narrow the scope to the point where you can conduct experiments, then your experiments won't support a conclusion that's broad enough to be a sound foundation for "expert consensus is more likely to be correct".

I happen to think expert consensus is generally useful, but there's still an element of faith in my opinion.


To put a finer point the phrase "expert consensus" is circular itself as we tend to take away the "expert" label from anyone whose position diverges too far from the consensus.

Of course it's not 100% black and wide and there is an element of faith.

The consolidated statement is way to wide, but if you take consensus to mean "a large majority like 66%+ portion of the scientific literature within the field(s) relevant to that specific instance" that becomes a lot more testable for an individual issue.


> there is an element of faith

That's exactly my point.

>if you take consensus to mean "a large majority like 66%+ portion of the scientific literature within the field(s) relevant to that specific instance" that becomes a lot more testable for an individual issue.

Yeah we can say that for some specific issue like choosing what time of year to plant tomatoes, expert consensus is useful, but that doesn't generalize, which was also my point.


Belief in experts is itself sound scientific reasoning about the available evidence on experts.

It’s like a chain of custody in legal evidence. If someone presents evidence in court and states that there are logs, seals and timestamps proving the chain of custody and disproving tampering, it is not “an act of faith” to believe the evidence was preserved accurately, even though you only observe details about the chain of custody, not the state of the evidence itself at all times.

It’s similar with expert opinion. You can think of the evidence (which you don’t personally observe) as passing through a series of chain of custody transactions - initial data collection, data preparation, actual study or research, proposed models, fact checking and testing correctness, presentation of results, use in an application / prototype / clinical trial, etc.

Believing in the fidelity of this chain of events is itself amenable to scientific and inductive inquiry.

Just like some rare case where police or attorneys lied about chain of custody with evidence that did get tampered with, sometimes this model of continuing trust at each step of the chain is wrong. Sometimes the chain of events that led to an expert opinion is untrustworthy - someone falsified data or lied, or there was an undetected error.

But that means it is a statistical process with an error rate, not that it contains any aspect similar to faith.


It seems to me that "belief in experts" or not is kind of analogous to the longstanding conflict in Western culture between Catholicism vs. Protestantism.

I mean, philosophically, both sides have good points about fundamental flaws of the other.


The difference between belief and faith is that belief may be substantiated by evidence and can change with new evidence.

I believe that kangaroos are real. If there were suddenly overwhelming evidence to the contrary, I would say okay and start believing that they probably aren't real, not stay firm in the original belief and dismiss the new evidence as a test of my faith.
