The Triple Filter Test

There's a common knowledge story kicked around about "The Triple Filter Test." Sometimes it involves Socrates and other times it involves an Arab scholar, but the truth of the story is the same. Here it is:

***

In ancient Greece, Socrates was reputed to hold knowledge in high esteem. One day an acquaintance met the great philosopher and said, "Do you know what I just heard about your friend?" "Hold on a minute," Socrates replied. "Before telling me anything, I'd like you to pass a little test. It's called the Triple Filter Test." "Triple filter?" That's right," Socrates continued. "Before you talk to me about my friend, it might be a good idea to take a moment and filter what you're going to say. That's why I call it the triple filter test. "The first filter is TRUTH. Have you made absolutely sure that what you are about to tell me is true?" "No," the man said, "actually I just heard about it and..." "All right," said Socrates. "So you don't really know if it's true or not. Now let's try the second filter, the filter of GOODNESS. Is what you are about to tell me about my friend something good?" "No, on the contrary..." "So," Socrates continued, "you want to tell me something bad about him, but you're not certain it's true. You may still pass the test though, because there's one filter left: the filter of USEFULNESS. Is what you want to tell me about my friend going to be useful to me?" "No, not really." "Well," concluded Socrates, "if what you want to tell me is neither true nor good nor even useful, why tell it to me at all?"

Most people leave it at that and assume that the story is just about the information we spread. The real truth behind it, however, is about the information we seek and create. Imagine how different the world would be if we only chose to seek or create information that was true, good, or useful. Those of you who have been reading this blog for a bit can probably figure out that it's the test that I've been using the whole time.
