Title: “How Should We Respond to Evidence of Boltzmann Brain Superabundance?”
Abstract: A “Boltzmann Brain” is a “brain” that forms by chance in an otherwise disordered region of space. Some leading cosmological models predict that in the future history of the universe, there are sure to be numerous Boltzmann Brains that pass through a sequence of physical states that mirror states of your own brain over the last several seconds. Plausibly, these Boltzmann Brains would have an episode of conscious experience that is phenomenally equivalent to your recent experience. In this paper, I assess the skeptical challenge posed by scientific support for Boltzmann Brain superabundance. I begin by critiquing a recent treatment of Boltzmann Brain skepticism by Dogramaci, explaining why his response has absurd implications and is not germane to the most formidable skeptical worry posed by predictions of Boltzmann Brains. I then consider other responses, including an argument articulated by Kotzen and Chalmers that says that the coherence of one’s present experience provides strong evidence against theories predicting Boltzmann Brains. While this argument has promise, it depends on controversial principles of “observation selection theory” that can be used to support dubious positions such as an anthropocentric theory of consciousness.
