Part 3/7:
The Halfer Perspective
Those who align with the Halfer perspective argue that, regardless of when Sleeping Beauty awakes, the coin remains fair. The foundational assumption is that prior knowledge about the nature of the coin remains unchanged throughout the experiment. Hence, they assert that since the coin is fair, the probability of it landing heads (H) is 50%. From this viewpoint, the question posed to Sleeping Beauty doesn't yield new information to alter her prior belief.
