I would say, rather, that there is an ideal unbiased recounting of events that is approached with various degrees of fidelity and we all sort of agree to call reporting that is reasonably close to this ideal as "unbiased".
This is not naïveté, since pretty much everyone readily admits that truly unbiased reporting is impossible. But some people are doing their best and some ... are not.
I do not believe that those in the news are in a significantly better position to discover it either.
This strongly suggests that we should assume that all recountings are biased. It is just sometimes easier to find the bias than it is at other times.
You can only accept information from others as "someone wanted to communicate this to me" and speculate on their real reasons for doing so.
We just have to do the best we can with the limited, imperfect information available to us. Our very senses lie to us.
If your notion of rationality requires there to be Perfect Truth then you're SOL right at the start.
One of our biases is towards conservation of mental energy. If we can, we choose the easiest path. Which means that we actively prefer experts who are smart, well-informed, and certain of their beliefs. Because we can then be comfortable handing our thinking over to them. Why bother questioning the expert when we'd surely agree if we just knew enough? And then confirmation bias keeps us from ever questioning their results.
The result, as https://www.amazon.com/Expert-Political-Judgment-Good-Know/d... documents, is that our most popular and highest paid pundits have those characteristics. But those experts are ALSO the ones who are worst at making predictions about the world. As I pointed out in https://www.lesswrong.com/posts/TMgfapzbt5qp4Hszf/doubt-cert..., we should really be concluding "likely has cognitive bias" instead of "the expert says it, so case closed".
The documented result is that we wind up trusting the experts that we should trust least!
Trust A over B when C (subject to real time limits on computing C) = ok
Trust Less = harmful
One group cannot speak on all things, they just cannot have all the required knowledge, experience, and practice to accurately judge more than a few corners of reality. The modern jack of all trades can only really have a surface level understanding of most things.
Who does? Not everybody, everywhere, certainly.
Holding fixed abstract ideas in mind for long periods of time, with conviction and a drive to keep them all consistent is a very peculiar, intellectual way of seeing the world, mostly only useful for debate team members, monks, academics, and political pundits. Especially for the countless political and metaphysical ideas that have no relevance to daily actions.
Most people don’t need to do that, and many who do it now have learned to perform it because it’s come to seem normal or even celebrated. But even a lot of them are terrible at it, hanging onto all kinds of sloppy beliefs and inconsistencies.
By default, most people just do shit and say shit and carry on with their day. Their natural BS detector looks like “God, the news program is awful. Turn it off.” and their natural political orientation is whatever makes for the most satisfying conversation with their neighbors.
What you might want to do, instead of all the complexity you’re trying to navigate and systematize, is to just unplug a bit and busy your hands instead of your brain.
You don't believe one camp or the other. You look at how each camp reports on the same event. You use them against each other to get closer to the truth, like a trial where both sides argue their case and you are the judge.
So many times I've seen primary sources as reported by a user posting a video on Twitter, and later I'll read news coverage of that same type (from either side), and they'll omit essential pieces of information that don't fit their narrative, or include irrelevant information that pushes their narrative. The latter category is often an attempt to frame your thinking or make you think a certain way about a target.
To me that says that looking at the two different sides and judging their arguments to arrive at the truth works.
A final test would be to see if your arrived truth is close to reality, without relying on human observers. This is done by using your truth to make predictions and see if those predictions come tru. To see if your model of reality has predictive power.
For example: a hospital in gaza is bombed by israel forces. Hamas claims X number of civilian deaths and says nothing about terrorists existing in the building. IDF doesn't claim any number of civilian deaths but does say that, generally, terrorists hide in these hospitals. No one confirms basic facts like who are the people being targeted, were they actually killed, and how many innocent civilians were calculated as an acceptable loss to destroy the targets.
Overall I feel I'm left with even less information than when I started, since all either side can confirm is that Israel bombed a hospital. And this happens for a bunch of things: Israel bombs a neighborhood the UN has labeled a refugee camp. Hamas commits an act of terror with some number of hostages taken.
I cannot even confirm if the food, water, and fuel being sent humanitarian-ly to Gaza is enough for the population there. One side claims there is a huge crisis of resources, the other side claims there's no crisis whatsoever.
Lying is not only seen as morally justified but as your duty because your life and your compatriot's lives are on the line every second of every day of the conflict.
The difference in conclusions is thus: suppose we had a computing device that could make the NP complete step (#3 in the post) P instead. It would mean that in such a scenario we could rationally analyze partisan news.
What I'm saying is that even given such a device, we could not. Given [1] above we would also need a device that could generate all possible observations and accuracies to attempt to fill in the missing information - which requires infinite computation. But [2] makes it even more intractable, where we have to not only compute all possible observations, but also consider all scenarios where there is no observation to report (with it's own set of accuracies) -- an even larger infinity.
The article's supposition can be resolved simply by observing enough partisan news (reported from every partisan angle) that you can put error bars on the reported information. Reality is such that you could observe all partisan news and still not know what's going on because there would simply be information gaps that would be irretrievable without infinite computation.
While I assume that you get true (though filtered) statements from some on each side, I'm also assuming that there are unreliable (read dishonest) sources as well. And each side is making the case that the other side can't be trusted. Which therefore means that we should expect (as actually happens) to be getting inconsistent information from different sources.
I didn't walk through it in detail, but that is the source of the problem. I start out convinced by one side. Then I observe someone I trust confirming someone I don't trust. Now I wind up trusting someone on the other side more. But as I iterate through my cascade of belief updates, this creates a feedback loop. Strengthening my belief that that person is trustworthy, strengthens my belief in other things that they claimed. Which causes me to trust others on that side more, and trust "my" side less. Which causes me to reevaluate more statements, and so on.
The critical question is, "Does this feedback loop die down, or does it continue until I switch sides?" That's the numerically intractable problem which computer scientists have proven to be NP-hard. And being forced to choose between two networks of conflicting beliefs is exactly the situation which causes the biggest problems.
Moving on, I agree that being able to evaluate the Bayesian update would not make this computable. I offered a straightforward example - unproven statements of mathematics, encoded as statements about economics. But your current line of argument is exactly the argument of the post that I was responding to.
Many people hold no particular beliefs whatsoever on most topics. When pressed they'll generate a "belief proxy" at random until the partisan sources their mental models are fed by gives them an observation to hold to. It's perhaps not mathematical, but it's highly observable -- particularly on topics that are likely to be highly partisan.
> The point will invariably arise: "This tells me how to listen to a foreign radio. Okay, I'll get the news, the lectures, the plays—all the rest of it. But so what? How am I going to know what's the truth and what's propaganda? How can I tell 'em apart? Tell me that!"
> The answer is simple: "If you agree with it, it's truth. If you don't agree, it's propaganda. Pretend that it is all propaganda. See what happens on your analysis reports."
(If I understand TFA, Linebarger's proposed 1948 sol'n seems to lie in not updating beliefs, or at least not so aggressively?)
I would say that his solution is to analyze it twice, once from your current view, one from a cynical one. Look at where you get changes. Those are places to look for possible errors in your current thinking.
I'll have to try that out and see what I think of it.
I much prefer that partisan actors pursue their incentives to include competing details, from which I can synthesize a Bayesian analysis of what is most likely to have happened. Often, the attempt to slander partisan coverage of events is done to cover up for partisan reporting masquerading as "objective" while omitting or massaging crucial details that only the slandered opposition will point out.

Nazis who despised us and everything we stood for nevertheless studied the photographs of our new light bombers. The appeal of credible fact is universal; propaganda does not consist of doctoring the fact with moralistic blather, but of selecting that fact which is correct, interesting, and bad for the enemy to know.

Fibbers’ forecasts are worthless. Case after miserable case after bloody case we went through, I tell you, all of which had this moral. Not only that people who want a project will tend to make innacurate projections about the possible outcomes of that project, but about the futility of attempts to “shade” downward a fundamentally dishonest set of predictions. If you have doubts about the integrity of a forecaster, you can’t use their forecasts at all.
We have the tools to find the truth, at least for many parts of our government. If you go look at CSPAN programming which allows the public to comment, or watch "debates", you'll notice a lot of empty chambers and very old people with nothing better to do being the only participants.
This is why we turn to partisan news. Shame on us.
> This is why we turn to partisan news. Shame on us.
You're omitting an important point to be a scold: "finding the truth" by combing through raw CSPAN feeds and primary documents takes such an extreme amount of time and effort, that literally no one has the ability to do it. Think you can? Watch a TV like this https://www.youtube.com/watch?v=cFwPFQXQHNk, except with 1000 channels instead of six, all playing programs you have to closely attend to. The "very old people with nothing better to do" are some of the only ones with the time to even dabble, and even they fail.
The best you can do is figure out a tiny, tiny little part, and most people don't even have the time for even that. So people divide up the work and rely on proxies, and others realize that exploiting those proxies can bring power.
It's an impossible problem. Shame on no none.
So the "better" sources have an uphill fight to be influential.

None of these are guarantees of trustworthiness, but a lack of them is in my experience a warning signal.
Sometimes you can tell a lot by what a given source leaves out about a given story. You find what's "allowed into the narrative" and how that evolves over time. Can be more interesting than the story itself.
Media literacy, in particular a rather (dare I say) postmodern approach to understanding the process of narrative construction, helps a whole lot to see through the ideological underpinnings. It actually helps quite a bit to triangulate an approximation of the truth by understanding not only the partisan bias in interpreting facts but also what different outlets might choose to include or not in their stories in order to further ideological arguments as well as how they might try to think for the reader to lead them from bare facts to interpretations that feel like facts.
If I have lots of beliefs, like every fact in a news story is a belief, then even an O(n) updating process seems overwhelming.
If my beliefs are just big things, like “people in states governed by political party X tend to have better outcomes by the metrics I care about,” then I think I only have like a handful of beliefs and I don’t really care about the big-O cost of updating them.
