    The Doomsday Argument and the Number of Possible Observers.Ken D. Olum - 2002 - Philosophical Quarterly 52 (207):164-184.
    If the human race comes to an end relatively shortly, then we have been born at a fairly typical time in the history of humanity; if trillions of people eventually exist, then we have been born in the first surprisingly tiny fraction of all people. According to the 'doomsday argument' of Carter, Leslie, Gott and Nielsen, this means that the chance of a disaster which would obliterate humanity is much larger than usually thought. But treating possible observers in the same (...)

    Philosophical Implications of Inflationary Cosmology.Joshua Knobe, Ken D. Olum & Alexander Vilenkin - 2006 - British Journal for the Philosophy of Science 57 (1):47-67.
    Recent developments in cosmology indicate that every history having a nonzero probability is realized in infinitely many distinct regions of spacetime. Thus, it appears that the universe contains infinitely many civilizations exactly like our own, as well as infinitely many civilizations that differ from our own in any way permitted by physical laws. We explore the implications of this conclusion for ethical theory and for the doomsday argument. In the infinite universe, we find that the doomsday argument applies only to (...)
