Self-Locating Belief and the Sleeping Beauty Problem

Adam Elga's article discusses the Sleeping Beauty problem, a thought experiment that raises questions about how one should update beliefs when uncertain about one's own temporal location.

The problem involves a person being put to sleep and awakened either once or twice based on a coin toss, with memory erased after each awakening.

Elga argues that upon waking, the person should assign a credence of 1/3 to the coin having landed on heads.
