At some point I heard of a word/concept/law about the expected lifetime of inanimate objects.
Something about how books that are on the charts for one week are expected to stay there for another week, but the ones that make it to two weeks are expected to make it to 4 weeks, etc (average)
I think it was a power-law or possibly related to Zipf’s law…
Does this ring a bell for anyone? My google-fu has proven woefully not up to the task.
Gott’s rule. It’s a simple application of Bayes Law with a uniform prior.
To elaborate a little on that, it has been formulated by phycisist J. Richard Gott. He calls it the Copernican principle. A less general form of it is the Doomsday argument.

Wow. Color me embarrassed! Old age must really be getting to me.
Asking the same question two times in a row. Perhaps this time it’ll stick.
Thanks all!
There are other examples of people asking the same question twice (Help me ID an old short story I read? - Cafe Society - Straight Dope Message Board).
