That's stuff that happens *all the time* in hard sciences
How do you know? It seems to me it could easily be an illusion created by the historians of science being biased towards that "knew it all along"-type-of-thinking.
It's not a historical issue, this stuff happens every day. It's how experimentation works in the hard sciences. Sometimes not grand or interesting, mostly little stuff. The point is the pretty much undeniable confirmation of predictions.
Science is on a spectrum, as I said, so what we're dealing with is a matter of probability and frequency of those predictions being made and confirmed. When it drops too low, the noise takes over and the signal is nearly lost.

No, that's not the issue. You're missing the point. It's not about guessing and being right, it's about hypotheses that can reasonably be expected to be confirmed or disproved.
You'd probably want to look at a faster moving science, though. Today most astrophysicists are probably closer to very sophisticated cartographers. Discoveries are mostly application of known laws. There is still movement and experimentation, and discovery of new principles... just a little slower.
teo123 wrote: ↑Sun Feb 03, 2019 9:13 amSo, do you think we can't know with reasonable certainty that, for example, the Holocaust happened, just because it's a fact of history and not of physics?
You can look at specific claims, like that there were gas chambers at X location. You can test the rocks and get a very convincing p-value that yes these rocks were exposed to that poisoned gas.
Many specific claims about the holocaust were recent enough to be tested, and that gives the account credibility when all competing "theories" are ad hoc. Thus with no competing hypotheses offering evidence to support them, that's the one you should err on.
However, when we have pre-Photoshop photographic evidence and countless first hand accounts (in English and other living languages) that kind of testing is typically not even necessary to know.
In order for the Holocaust to be false there would have to be a grand conspiracy and cover up, and we can use statistics to roughly assess the probability of such a conspiracy happening and show how unlikely it is. Beyond a few dozen people that's virtually impossible. You can't predict the behavior of any one person easily, but as it scales up it becomes more reliable.
If you had somebody (or thousands) who actually lived through the adoption of those words and knew first hand the original meaning, and could tell us that in English, then that would be something.
This is why most history relies on direct accounts from ancient historians and writings from those periods: actual accounts.
We can also recover artifacts, but that's usually just to confirm the accounts.
When you start speculating and interpreting that's where it starts getting immeasurably uncertain.
This also applies to accounts that are in dead languages or dialects that have to be translated. The translation itself will always add a layer of uncertainty to the account. NOT just that the person was lying or mistaken (unlike for something like the holocaust, since we have few accounts of ancient history that's possible and even pretty likely), but also that we may have translated it wrong which becomes more probable the more distant the language is. The problem is, though, that we have no way to assess the probability of a mistranslation.
No P value = soft science. You have to guess at it based on your feelings.
You might devise a way to assess the probability of mistranslation based on a few variables like how long the language has been dead for and how unrelated it is somehow. That would be amazing and it would go a long way to hardening history and linguistics.
The point is that we don't have a lot of that now, so these are currently soft fields.
A soft science can become a harder science, but it's a difficult task. And for some where we're unlikely to ever find the hard evidence we need to reliably confirm or disprove prediction it might be impossible.

Well, to be honest, I think there may be some truth to that. Not precisely to the Holocaust (since the evidence that it happened is truly overwhelming), but to, for instance, the Massacre Of Vukovar in 1991.
Smaller events can be less certain. How many first hand accounts do we have confirming those facts?
teo123 wrote: ↑Sun Feb 03, 2019 9:13 amHow can we know for certain the Serbian president Slobodan Milosevic was even aware of that?
This is more complicated.
I don't know all of the details there, but speaking generally of blaming those in power:
We assume leaders are aware of what happened under them, because it's their responsibility.
Either they failed in their responsibility in which case they should be punished, or they knew... in which case they should be punished.
There's always some level of plausible deniability, but you can't allow leaders to escape punishment by scapegoating others and claiming ignorance.
Without punishment, rulers will correctly assume they can do whatever they want and get away with it.
It's unfortunate if a few innocent morons get their heads put on the chopping block, but even if somebody was innocent of the act (and only guilty of stupidity) it's important to establish a precedent that those in power be held accountable for abuses that happen when they're in power. They all need to know that the sword of Damocles is hanging over them, and that they can't get a pass by turning a blind eye to abuse and being technically ignorant.
teo123 wrote: ↑Sun Feb 03, 2019 9:13 amOK, so, how do you estimate the probability that the Newton's Second Law is true? Doesn't make much sense to ask that, does it?
You don't really do that after the fact.
You look at experiments. You could do a new experiment and look at the probability of the outcome proving the law. The larger the experiment, the higher the chance you proved it.
Now if you wanted to, you could do a meta-analysis of ALL of the experiments to ever be done on it and find the probability based on historical experiments, but that risks selection bias.
teo123 wrote: ↑Sun Feb 03, 2019 9:13 amA world in which the Newton's Second Law is not true is not quite conceivable (unless we assume that's a world without any change in movement, which our world obviously isn't),
Previous results could have been due to inaccuracies in measurement. This would just be astronomically unlikely.
However, perhaps we could conceive of a world where mass doesn't influence it, but instead it's volume (for some reason).
You can create alternative physics, even make a simulation with them. Video games often function on alternative physics.
teo123 wrote: ↑Sun Feb 03, 2019 9:13 am
since the mere definition of "force" relies on the Newton's Second Law to be true.
It would just mean something else.
Yes, all physics is intertwined, so a change in anything would have huge ripple effects. The point is that these experiments can and do have p values.
Often in physics, though, because it is a very very hard science, those p values are so extreme that probabilities approach 0% or 100%. It's basically yes or no.
The more dichotomous results are, typically, the harder the science.
When you hit probability of 50% when there are two plausible alternatives, you're down to a guess.

So too does the mere definition of the language rely on the sound changes to be regular, because a language in which the sound changes weren't regular wouldn't be intelligible to other speakers of that same language, and therefore it wouldn't be a language. It sounds like circular reasoning at first, but it really isn't, it's more of a proof by contradiction.
You're going to have to state that more clearly, because yes that does sound like nonsense.
Language is merely the meaning we give to abstracted representations to communicate ideas. Symbols, sounds, etc.
The point is that those things have no inherent meaning, but are interpreted by the receiver to have a meaning which is close enough to the meaning the originator had in mind when creating the abstraction that they can understand each other.
A big problem is that "understanding" is hard to measure.
But there's nothing in the nature of language that says anything about sounds or how they change over time.
A language could be a random combination of sounds assigned to each concept, as long each party has the same set and as long as that combination was stable between the time the speaker and listener learned it and the sound was exchanged and interpreted.
You could have a language where each person gets a memo every day for the new sounds for each idea, randomly generated for the day (but they all get the same memo). It would be very inefficient, but it'd still be a language.
It's plausible that there's something in human psychology that makes languages change in consistent and predictable ways so that people from different regions will not quickly lose the ability to communicate with each other due to drift. It's a tendency you'd have to prove, though, and show the probability distribution for.
Could even be mere physiology. Again, needs evidence.

The thing that went wrong was the thing for which there was no (or inadequate) regulation. Now we have regulation on that thing, and the exact same thing can't go wrong again in that way.
The issue is that regulating an economy is kind of a game of whack a mole. People only admit a problem and regulate for it after something goes terribly wrong.
Can we foresee problems and regulate before they happen? In theory, sure. But in practice we can not because there's not the political will to do so.
Kind of how the current U.S. measles epidemic is going to keep getting worse until people realize these ideological vaccine exemptions are a problem and the loopholes are finally fixed. It'll have to get really bad before there's political will to do anything about it, though.
That's a big problem with the political systems in place today: they tend to react after the fact.
Same thing with 9-11, etc. There was intel, it was just a mess and people didn't take terrorism seriously despite warnings.
Same thing, on a personal level, with somebody who eats junk all of the time and doesn't clean up his or her diet until he or she has a heart-attack scare.
This comes down to human psychology. Not what government should do, but what it will do because it's run by human beings who are VERY bad psychologically at risk assessment and don't trust numbers or experts until they feel it personally.

It's a CHANGE in government spending. Stop being an idiot.

Stop being an ignorant moron. You do not understand what these regulations do. You do not have the education or experience to assess them.
If you worked in the industry, maybe you could start criticizing the regulations relevant to your industry. For sure, there are some less productive regulations, even some bad ones, but regulation is also vitally important to protect human life and investment.
Like with anti-vaxxers lack of experience with disease, you've just lost touch with the experiences that taught us why each regulation was important.
YOU didn't experience the problems, so you doubt the importance of the regulation. It's a profound ignorance coupled with arrogance.
teo123 wrote: ↑Sun Feb 03, 2019 9:13 amHow can you let people vote on the economic issues? I explicitly said that the good economic policies are unlikely to be followed in a democratic society...".
Yeah, people are pretty dumb, which is why regulations only tend to go into effect after something bad happens... as I explained.
They don't prevent all the bad things because democracy requires a tragedy to get off its ass and pass regulation to prevent future ones of the same time. And hopefully idiots like you don't undo the regulations the next generation because they couldn't be bothered to try to understand why those regulations went into effect in the first place.

Not really true; many have ambitions to move up, and saving money can be a good way to do that. Even enter politics. Many political campaigns run on that.
Where it doesn't tend to apply is in military spending... I'm pretty much with you if you want to mostly abolish that.
Some of these companies need to be broken up because they've effectively established monopolies. There are some issues of money in government reducing the ability of politicians to break them up. However, that's a failure of regulation to be employed, not something that's bad about regulation in principle- we're not better off without the laws that break up monopolies just because they aren't always used.

Friedman was a big advocate for testing policies and judging by the results.
Really? He was often criticized for relying on simplistic models (to explain, for instance, why the minimum wage can't work) and dismissing the empirical data.
No surprise. Confirmation bias, of course.
Don't make the same mistake.
