Your link doesn't work for me, but I searched on the phrase to see what it was all about. It's very close to the fallacy I'm talking about. But I don't think it's exactly the same thing. It's about seeing a double-six roll of the dice and assuming that there must have been many previous rolls in order for such an "improbable" combo to appear. "My" fallacy, on the other hand, results in a conclusion that the improbable result was guided, or intended, even if it's only a single roll of the dice.
Still, I'd never heard of the inverse gambler's fallacy before, and I appreciate the info. A friend of mine who teaches philosophy says it's not all that unusual for a "new" fallacy to observed and named, and he likes "my" fallacy. He agrees that applying a name to a fallacy makes it easier to spot it, and to criticize it.
