Short story by Isaac Asimov describing the true story of how a vast war was won. Everybody thinks that it was a massive computer, which gave strategic advice. But the hackers who run it sit around explain to each other what really happened. See Monte Carlo.

To elaborate a little more, in this short story by Isaac Asimov, you discover that all the great war-winning decisions made by a massive computer eventually just came down to a single human flipping a coin.

The story is more of a tribute to statistics (= The art and science of lying) than it is a tribute to computer science.
