And you go on and on about the fallacy of computer models but admit that they are frequently used. In today's world, they are an essential tool. And any judgement can be quantized. Why? Because judgement is based on history and history can be quantized depending on what you want your response variable to be. You yourself admitted that some of the tools that are causing the markets headache today are useful when applied correctly. Well, all those tools are nothing more than algorithms.
Finally, considering that the Federal Reserve isn't perfect in their judgement, I fail to understand why you would have a bias in favor of them as opposed to computer. Do you second guess your computer when it outputs a solution to your calculations? No you don't so why be weary if it gives you a number based on all the data you've given it? The truth is, the men and women at the Federal Reserve outsource all their quantitative processing to computers. These processes produce qualitative estimates and predictions. The humans then add their own input, which is short term politicising.
Provided the given model has been stress tested and is constantly updated on a daily basis, I would trust a computer more than a technocrat who has to worry about his job, employment, and reputation.
The Fed's role in ensuring solid growth is not a major problem, they provide liquidity when needed and contract it when it isn't. The indication of this is price instability. However, even with the recent issues, price instability hasn't been huge. It wasn't until recently that they had to choose liquidity over potential price instability and chose liquidity in the face of a massive economic disruption.
I do frequently use them. I use monte carlo simulations that determine cashflow losses on billions of dollars worth of securities. However, the fallacy in all of these are the static nature of the input variables. By the time I run them, they are already old. When one inputs economic data you get additional problems, in that economic data changes with the winds, consumer mentality is often at odds with itself and can turn on an atom.
I say that models can be useful, but when it comes down to a "gut" check, they aren't perfect. For example, if a model tells me that a 'A' bond will not sustain losses, except out to 5 standard deviations, but then changing economic times and my down gut says that that's not enough, considering everything about a seller/servicer, I may require protection 7 or 8 standard deviations out. A model didn't tell me that, I used my own intuition based upon all new information. Models and computers cannot hope to hold a candle to the human brain.
I second guess models all of the time, as does any smart person. If models were so infallable, then why are stock analysts constantly wrong? I have built extensive DCF and DAE models including econometrics which turn out wildly different results than reality. I'm not talking about simple things, I am talking about spreadsheets with dozens of tabs, each with their own inputs into GDP, interest rates, employment, consumer sentiment, latest default data on consumer loans, CPI (headline and not).
All of those are run using the latest statistical methods with significant scenario analysis. I created such a thorough model for analyzing companies during my MBA that my securities analysis professor uses it currently. It took about 6 hours to run 200 scenarios.
Even then, it was wrong most of the time. Why? Because within that 6 hour period the whole world changed, sometimes significantly.
The Fed is imperfect in judgement, because nothing is perfect when it deals with predicting human behavior, because human behavior CANNOT BE PREDICTED! When it comes down to it, computers will never be any better and will likely be much worse, than humans, at predicting human movements.
Your "politicising" is nothing more than opinionating, you're attempting to categorize any opinion as a partisan decision, but saying that a human programmed computer will be independent. How then, will it be independent if the decisions it makes depend on programming?
Are you then, seeking a truly independently minded AI which is capable of it's own decisions, outside human programming and hueristics?
At this point, it's impossible.
