When Christopher Nolan was promoting his previous film Interstellar, he made the casual observation that "Take a field like economics for example. [Unlike physics] you have real material things and it can't predict anything. It's always wrong." There is a lot more truth in that statement than most academic economists would like to admit.

[...] several famous Keynesian and neo-classical economists, including Paul Romer, [...] criticized the "Mathiness in the Theory of Economic Growth" and [...] Paul Krugman. In this instance, though, Krugman is mostly correct observing that "As I see it, the economics profession went astray because economists, as a group, mistook beauty, clad in impressive-looking mathematics, for truth."

[...] But more fundamentally, as Austrian economist Frank Shostak notes, "In the natural sciences, a laboratory experiment can isolate various elements and their movements. There is no equivalent in the discipline of economics. The employment of econometrics and econometric model-building is an attempt to produce a laboratory where controlled experiments can be conducted."

The result is that economic forecasts are usually just wrong."

"[Levinovitz] approvingly quotes one economist saying "The interest of the profession is in pursuing its analysis in a language that's inaccessible to laypeople and even some economists. What we've done is monopolise this kind of expertise.[...] that gives us power.""

[...] because economics models are mostly useless and cannot predict the future with any sort of certainty, then centrally directing an economy would be effectively like flying blind. The failure of economic models to pan out is simply more proof of the pretense of knowledge. And it's not more knowledge that we need, it's more humility. The humility to know that "wise" bureaucrats are not the best at directing a market "

Economists Are the New Astrologers

    It is not economics that is bad, it is believing that you can do meaningful predictions about what interfering in the market will do that is false.

    They do say that that we don't know, and that we can never ever know, as a matter of epistemology.

    Ok. Consider this thought experiment. We're trying to figure out the consequences of interfering in the market in a certain way. So... we just do it and see what happens. What you are claiming is that somehow we can't then in near identical circumstances make predictions based on what happened before. Sorry I don't buy that economics is that unpredictable.

    Actually if economics is just unpredictable, then it is also unpredictable what meddling with it through regulations will do. But that means that it does not matter whether there are regulations or not, because if the regulations had any predictable effect, that would contradict unpredictability. Therefore it is logically inconsistent to claim at the same time that economics is unpredictable, and that regulations are always harmful.
