The Birds And The Salmon - A Short Parable
Jan. 7th, 2010 01:53 pmA burly, gray-bristled fisherman once lived in the islands of Alaska, where he ran a small salmon boat. In the spring, when they were feeding, the salmon would drive great schools of herring to the surface. The herring, in turn, attracted huge flocks of birds, which scooped them from the water and ate them. He learned early on that when such a flock appeared, the salmon would be biting especially well.
One day, feeling the strain of age, he decided to hire a cabin boy to assist him with his duties. On their first day out, he spotted a flock of birds and instructed the cabin boy to steer towards them. "But captain", the boy protested, "how can the birds attract fish?"
"Shut up", the captain replied, "and keep fishing."
But the boy would not let up. Every time the birds appeared, he would try to explain why birds could not possibly attract the salmon. One day, he said "Captain, the salmon cannot see the birds from under the water, even when they are right below. How could they travel from far away to find them?" The next day, he pointed out that birds flocked all year, but the salmon only appeared in the spring. "Why do you think the birds bring salmon when they have obviously failed to do so for the past eight months? Your theory cannot possibly be correct."
On occasion, the captain would grudgingly take the boat to some other location where there were no birds, and would catch little. After several months, he grew cranky, and grabbed the boy by the shoulders. "What the hell is wrong with you, boy? Every time we follow the birds, we get salmon, and every time we go elsewhere, we come up with nothing. Can't you see that this WORKS?"
"Captain...", the boy replied solemnly, in a low voice. His lips trembled with the passion of his words.
"Captain... I must tell you: correlation does not imply causation."
The captain lifted the boy in the air and threw him overboard, leaving him to drown. Soon after, he found a new cabin boy who was not so stupid. They fell in love, caught many salmon, and lived happily ever after.
The end.
