For the entertainment of the forum, note the following:

Evidently the state of california commissioned a survey every 2 years of the oil price forecasts of various businesses and other organizations, and then summarized it as a "composite forecast". This relic is the 1997 version of this, which "forecast" a 90% worst case scenario oil price of $25 in 2004.
There is a table at the back that lists all of the old forecasts and compares them to the actual historical prices in 1997 dollars. The best forecasts of the current 2004 price were done in 1983 and 1985, when the spike of 1981 was still fresh in peoples' minds. These forecasts did not pick up the low prices of the 90's at all, though.
So what are we to learn from this?
First: The state shelled out some big bucks to produce this composite forecast which was off by a factor of 100%. Evidently they quit doing it at some point, because I could not find more recent versions. Nice work if you can get it.
Second: People tend to forecast not too divergently from their recent experience.
