In a groundbreaking study that has lasted more than ten years, CalTech researchers have proven that the human IQ is affected by fluctuations in humidity. This discovery, which culminates the total invasion of 1000 ordinary people's lives for the entire study period, shows a marked increase in a person doing "silly" things as the air they breathe becomes more moisture laden, culminating in near total idiocy during periods of extremely heavy rainfall.
Other departments at CalTech have immediately seized on the finding as a basis for many occurrences in human culture, including such prophetic catechisms as "He had enough sense to come in out of the rain," and the ever popular "you're all wet!"
Universities paleontologists are now reconstructing ancient weather patterns in a quest to explain mass migrations, the fall of ancient empires, and the election of George W. Bush to two full terms as U.S. President.
