The problem is that economics as a field spans from sociology and mass-psychology (almost impossible reason about, fully quantify or prove anything in a scientific manner) to mathematics (easy to reason about, model and publish results - but at the risk of not actually modeling the real world). The incentives of the academic world nudges researchers toward the math side of the field, but the risk in that is that the field becomes disconnected from reality.

On the contrary, sociology is way more scientific than economics in building probabilistic models of social behaviors. Such models are quantitative and testable.

Economics is opinion based by design.

This is complete nonsense, economics is by far the strongest social science field in terms of empirical methodology. Pretty much all the modern causal inference methods were developed in econometrics. Try taking a look at the big econ journals (like Journal of Political Economy, American Economic Review, or Journal of Finance) and I assure you you won't find anything resembling arbitrary "opinions".

Economics may be the most elaborate in manipulating mediocre data to support a hypothesis, but it is important to remember how incredibly easy it is to be wrong or mislead others when using data and complex statistical methods.

There is a simple method to disprove your wild claims that comes from system theory.

Regardless of the field, be it economics, cookery or mechanical engineering, you can ask a pool of experts:

- How can I solve problem X? What will happen if I do nothing?

- How confident are you that the solution will be effective or the prediction will be accurate?

The problem X is the input and then you compare predictions and real outputs.

There is abundant literature on the effectiveness of economical models and the ability to make prediction and the outcomes are clear:

- Economists systematically overestimate their ability to make predictions

- There is not even a single economical theory. Economists have different schools of thought that are incompatible with each other (!)

There are countless examples of economists failing to predict the future or having wildly different opinions.

Right, can science accurately model the 3 body problem? Or turbulent flows in fluids?

I guess science is a failure then, better give it up.

You are making a strawman.

Ask meteorologists about their models and they will honestly tell you the limitations of such models and the success rate at predicting the weather. They have little incentive to lie.

It will be difficult to find meteorologists with clear "anti snow" or "pro rain" biases.

Same goes for getting a blood check: they are not 100% reliable, yet it's difficult to find a lab with an ideological bias skewing the results.

Then, ask economists and you'll quickly find out that their predictions and advice on economic policies aligns with the school of though they belong to.

Politicians routinely ask for advice from this or that economist depending on what they want to hear.

Politicians commonly ask advice from this or that scientist depending on what they want to hear rather than looking for peer reviewed models. I would say that's a problem of a different nature.

Nice example.

Economics almost by definition can not make good predictions wanted by the public, because as soon you figure out precise model “a” of the economy, the economy takes the model “a” into account and mutates to model “b”.

This applies to all social science.

This applies to all social science.

That's a sweeping generalization, but ignoring that and assuming it's true: so what?
Re:Unsolved problems in economics by slothtrop on Tuesday May 17, 2022 @11:37AM (#31412280)
Your argument on sociology hinges on that not being true.

it's not a risk, it's a measurable fact.

The fact that it doesn't make predictions any more reliably than astrology.

yup.

Physics: apply force F to projectile of mass M and know in advance where and when it'll land modulo a tiny error margin.

Economics: raise the interest rates by X%, wait unknown amount of time Y, observe state of the system after time Y, formulate complex theory as to why action led to "cause", go write a paper about it. Get wined and dined by policy makers who see great benefit in your "explanation".

The phenomenon is not new BTW, oracle, druids and shamans have occupied that ecological niche for as long as there has been tribes and leaders needing to justify their actions to the masses.

They just changed their names in the 20th century to sound more respectable.

Re:Unsolved problems in economics by slothtrop on Tuesday May 17, 2022 @10:59AM (#31411685)
Were it reduced to "predictions". It isn't. And people take for granted a lot of popular concepts borne of the study as though it was always known. E.g. the relationship between interest rates & exchange rates, supply and demand, etc.
Re:Unsolved problems in economics by guerrilla on Tuesday May 17, 2022 @11:17AM (#31411983)
Any "science" that can't reliably make reliably make predictions isn't a science. That's the litmus test.
Re:Unsolved problems in economics by slothtrop on Tuesday May 17, 2022 @11:18AM (#31412011)
You've just eliminated all social sciences, by your metric of "reliably".

edit: your take-away from this should be that you're mis-defining science.

edit2: you all forgot that medical and nutritional science has a reproducibility crisis, it's no less "science" for it. Add to the fact, the notion that nothing is reproducible in Economics is false. See for example: https://www.caltech.edu/about/news/famous-economics-experime... , https://www.science.org/doi/10.1126/science.aaf0918

Because they're indeed not sciences.

They call themselves that to attract funding.

Predictive power and reproducibility are defining characteristics of sciences.

Social "sciences" have neither and therefore aren't sciences.

No thanks.

Volcanologists cannot exactly predict when a volcano will erupt. Seismologists cannot exactly predict when an earthquake will happen. Both can only offer uncertain probabilities. But these are definitely both sciences.
Re:Unsolved problems in economics by guerrilla on Tuesday May 17, 2022 @05:55PM (#31416751)
They don't have to predict everything, especially things that aren't predictable.
Re:Unsolved problems in economics by dotopotoro on Tuesday May 17, 2022 @05:06PM (#31416283)
What kind of precision of prediction is required? Economics predict some things. For example if you print exceedingly a lot moneys, inflation will happen.

At the same time, physicists have problem telling precise location and momentum of the atom (at the same time; precisely).

(footnote: I love physics more than economics, but world is not perfect and sciences are not perfect. Except for math maybe https://xkcd.com/435 . Perfection and usefulness are not the same)

Re:Unsolved problems in economics by initplus on Tuesday May 17, 2022 @05:13PM (#31416357)
Economists cannot predict exactly when market crashes will occur. Is volcanology not a real science because volcanologists cannot predict the moment a volcano will erupt?

In both cases scientific study can help us determine when the risk is higher or lower, and can tell us definitively when one does occur. But no field that studies stochastic processes like markets or volcanic activity can make 100% certainty predictions years in advance.

These fields are all dealing with probabilities, asking for a yes or no answer is missing the point.

Can you point me to any good quantitative research on astrology? Steelman style treatment, preferably. I haven’t actually looked into astrology with much seriousness. I worry that I might be like one of those people who dismiss economics because of envy or some other weird psychological mechanism. It sounds like you might have some information to share?
Re:Unsolved problems in economics by _just7_ on Tuesday May 17, 2022 @11:17AM (#31411986)
That's about as accurate as saying Medicine doesn't make any more reliable predictions than astrology
Re:Unsolved problems in economics by guerrilla on Tuesday May 17, 2022 @11:38AM (#31412285)
