The doomsday argument (DA), or Carter catastrophe, is a probabilistic argument that claims to predict the future population of the human species based on an estimation of the number of humans born to date. The doomsday argument was originally proposed by the astrophysicist Brandon Carter in 1983, [1] leading to the initial name of the Carter ...
Hanson received a BS in physics from the University of California, Irvine in 1981, an MS in physics and an MA in Conceptual Foundations of Science from the University of Chicago in 1984, and a PhD in social science from Caltech in 1997 for his thesis titled Four puzzles in information and politics: Product bans, informed voters, social insurance, and persistent disagreement.

If the doomsday argument can apply to itself it can be simultaneously right (as a probabilistic argument) and probably wrong (as a prediction).. Therefore, Landsberg and Dewynne argue that it is more likely that the doomsday argument is wrong (even if its logic is correct) than that the human race will become extinct in 9,000 years (which the doomsday argument calculates at around 95% likely).
The self-indication assumption doomsday argument rebuttal is an objection to the doomsday argument (that there is only a 5% chance of more than twenty times the historic number of humans ever being born) by arguing that the chance of being born is not one, but is an increasing function of the number of people who will be born.
He made a major effort subsequently to defend his form of the Doomsday argument from a variety of philosophical attacks, and this debate (like the feasibility of closed time loops) is still ongoing. To popularize the Copernicus method, Gott gave The New Yorker magazine a 95% confidence interval for the closing time of forty-four Broadway and ...

In 1993, Eckhardt's article "Probability Theory and the Doomsday Argument" was published in the philosophical journal Mind. [1] His follow-up article, "A Shooting-Room view of Doomsday" was published in The Journal of Philosophy in 1997. Both articles make arguments skeptical of the Doomsday Argument as formulated by John Leslie.
