Something similar caused the current financial crisis. First the financial regulators in Basel decided that the only thing they would care about was the risk of individual financial defaults and not one iota about any other risks; then though they must have known these were humanly fallible they still empowered some few credit rating agencies to be their GPS on default risks; and finally, by means of the minimum capital requirements for banks, they set up all the incentives possible to force them to heed what the GPS said and to ignore any internal warning voices.
Of course, almost like if planned on purpose, it all ended up in a crisis. In just a couple of years, over two trillion dollars followed some AAA signs over the precipice of badly awarded mortgages to the subprime sector. Today, we are still using the same financial risk GPS with the same keyed in instructions... and not a word about it in the recent Financial Regulatory Reform proposal
I hate the GPS type guidance of any system since I am convinced that any kid brought up with it will have no clue of what north, south, east or west means; just as the bankers not knowing his client's business or how to look into his client's eyes or how to feel the firmness of his client's handshake, can only end up stupidly following someone else's opinion about his client on a stupid monitor.
I hate the GPS type guidance system because, on the margin, it is making our society more stupid as exemplified by how the society, day by day, seems to be giving more importance to some opaque credit scores than to the school grades of their children. I wait in horror for some DNA health rating scores to appear and cause a total breakdown of civilization as we know it.
Yes we are buried under massive loads of information and these systems are a tempting way of trying to make some sense out of it all, but, if we used them, at least we owe ourselves to concentrate all our efforts in developing our capacity to question and to respond adequately when our instincts tell us we're heading in the wrong way.
Not all is lost though. I often order the GPS in my car to instruct me in different tongues so as to learn new languages, it gives a totally new meaning to lost in translation, and I eagerly await a GPS system that can describe the surroundings in more extensive terms than right or left, AAA or BBB-, since that way not only would I get more out of it but, more importantly, I would also be more inclined to talk-back.
