Another Perspective of the Sleeping Beauty Problem: What Lessons Can We Learn from the Sleeping Beauty Problem?

Abstract

The Sleeping Beauty problem is still an important issue in decision theory. Since Elga raised this problem in 2000, there are two opinions as to what the solution is, with some thinking the answer is 1/2 and others thinking the answer is 1/3. Even though both sides seem to have reasonable reasons to support their answer, there is still no convincing conclusion. In addition to attempting to solve this debate, this paper provides another perspective on the Sleeping Beauty problem: no matter whether the final answer is 1/2 or 1/3, it will not challenge our intuition to a fair coin.
