The problem with the estimate of only 175% chance of one intelligent
race per galaxy is that it relied on assumptions of the values of the
different factors in the equation (which you can find in Sagan's book,
Cosmos). Recently I had heard of this same gentleman plugging in new
assumptions based on data learned in the 25+ years since he formulated
this algorithm. He then came up with at least one intelligent race every
40-60 light years. I would be interested in seeing what the new data on
extrasolar planets does to this estmate.
