Slashdot: Are we alone in the Universe?
Slashdot points to a CNN article that has been justly taken apart for falling prey to a biased sample fallacy; we are currently only capable of detecting planets in close solar systems such that the planets we can detect preclude the formation of planets conducive to life as we know it. (The gas giants we can detect are too close to their respective stars to even have a habitable moon, as I understand it.) Ergo, of all the solar systems we have detected planets in, 100% of them are unsuitable for life.
