Agree 100%. The whole reason why market economies - economies based on the decentralized mechanism we call "prices" - work better than any other economic system is because they're decentralized. If one person or group of experts could know the current wants/needs of millions of individuals, we wouldn't need prices and that person/group could predict the direction of the economy.
Similarly, say all you care about is predicting a recession since that's going to risk your job/business/personal finances etc. As far as I know, there's no way to predict a recession until after you're already in one. Sure, a yield curve inversion has preceded every recession in the past ~50 years, but (1) that's only ~5 recessions (2) the inversion has taken place up to 33 months prior to recession and (3) as the Great Recession taught us once again, just because something has been true for many years in the past (housing prices always going up) doesn't mean it'll hold true in the future.
Macroeconomic forecasting is by and large nonsense. The PhD chief (macro)economists from big banks you see on CNBC will, at best, identify some recent trends that could cause the economy to change if said trends continue and, at worst, prognosticate. I wouldn't describe myself as an "economist" since I only hold a bachelor's of science in economics, but the prognosticators do a tremendous disservice to themselves and to the practice of economics.
So should you ignore all economic news and analysis?. No. You might be able to make some vague, general, long-term forecasts, like how I believe that the US economy will remain a major economic power 20 years from now (hence why I'm comfortable squirreling away cash into S&P 500 Vanguard index funds) and that Amazon will probably be a major company for most or all of that period, but I don't pretend to know whether inflation will be below 2% for any fraction of that period, if self-driving cars will replace Uber drivers, or if China's per-capita GDP will exceed that of the US.
You have to be careful to identify what's not knowable even when everyone else believes that something is knowable. When I did debate in high school (circa mid-late 2000s), we had a topic on whether the US government should increase investment in alternative fuels. Many arguments in favor relied on the assumption that oil prices would continue to rise. Some experts debaters cited even suggested the world had already reached "peak oil." Judges were receptive since they were paying $4.00/gallon for gas. Now, of course, if oil is a finite resource and our consumption/drive habits remain the same, oil prices will have to rise eventually without alternative fuels. But few people, including me, (at least few people who got media attention) realized that the then-high oil prices were both (1) inducing previously cost-prohibitive US oil extraction and (2) weakening the incentive of OPEC's members to keep production low. That was a lesson to me: conventional wisdom about the economy, even "wisdom" from "experts" in a segment of the economy, can be wildly inaccurate.
P.S. hot take: while it's clear that humans can and have changed the climate, it's not clear what the tangible effects will be... so while some investment in mitigation may be warranted (especially with respect to obvious pollutants), we should be careful not to incur massive costs today on the assumption that say, Miami will definitely be underwater in 50 years.

Conventional wisdom is wrong about all kinds of things, all the time. "Forecasts have been wrong, therefore forecasting is pointless" is the wrong lesson to take.
- pinky1417 7y agoBoth of your statements are true. However, I feel it would be a misrepresentation or, at least, a misunderstanding to say I suggested that "forecasts have been wrong, forecasting is pointless." Perhaps I'm misunderstanding your reply or I wasn't clear in my original post. The history of failure of expert consensus forecasts is one reason why we should be highly skeptical. That's why I said such a forecast, and you yourself quoted, "...can be wildly inaccurate" and not, as you suggest I said "...is pointless." Macroeconomic forecasting is indeed pointless, but for a different reason. Some might say it's pointless because the economy is a (1) complex and (2) chaotic system. The economy is indeed complex and chaotic, but so is the weather... and we can forecast the weather with accuracy and precision macroeconomic forecasters drool over. The economy has two additional and overlapping factors making forecasting effectively impossible: (3) two-way causality between the forecast and the economy (the forecast is based on the predicted behavior of individuals and individuals will change behavior depending on the forecast) and (4) the free will of humans.
