Between 1985 and 2005, boomsters made 10-year forecasts that exaggerated the chances of big positive changes in both financial markets (e.g., a Dow Jones Industrial Average of 36,000) and world politics (e.g., tranquility in the Middle East and dynamic growth in sub-Saharan Africa). They assigned probabilities of 65% to rosy scenarios that materialized only 15% of the time.
1985到2005年间，乐观主义者发表了一份10年预测，夸大了金融市场（比如道琼斯36，000种工业平均指数）和全球政治（比如中东和平与撒哈拉以南非洲国家的快速经济增长）中发生重大积极变革的机会。他们认为前景令人陶醉的可能性高达65%，而目前看来他们的预言只有15%变成了现实。
