How to consistently come to the wrong conclusion

Three blind economists are feeling an elephant in an observatory. One takes the trunk and pronounces it to be like a snake, one takes a leg and pronounces it to be like a tree, and one takes the tail and pronounces it to be like a rope.

Meanwhile, the astronomer is looking through the telescope at the asteroid that is about to strike the Earth...


While the bean counters were busy refining their equations, winning Nobels along the way, making their equations more perfect so that they better modeled their transactions, they forgot what everyone who has studied ecology knows: Equations work well for systems near equilibrium; the real world is almost always in disequilibrium... and there are asteroids out there...

Some call these sudden events that upset their equations "black swans". What they are really saying is that they wander around the world looking through a microscope, so they sometimes get hit by cars while crossing the street.
