artifact description
I present a solution to the Sleeping Beauty problem. I begin with the consensual emerald case and describe then a set of relevant urn analogies and situations. These latter experiments make it easier to diagnose the flaw in the thirder's line of reasoning. I discuss in detail the root cause of the flaw in the argument for 1/3 which is an erroneous assimilation with a repeated experiment. Lastly, I discuss an informative variant of the original Sleeping Beauty experiment that casts light on the diagnosis of the fallacy in the argument for 1/3.
