Scientific American quotes MIT Economist Andrew Lo:

“Economists suffer from a deep psychological disorder that I call ‘physics envy,’ ” Lo says. “We wish that 99 percent of economic behavior could be captured by three simple laws of nature. In fact, economists have 99 laws that capture 3 percent of behavior. Economics is a uniquely human endeavor and, as such, should be understood in the broader context of competition, mutation and natural selection—in other words, evolution.”

Make it the 100 law.
