These are great. Though Sleeping Mary can tell that she’s colourblind on any account of consciousness. Whether or not she learns a phenomenal fact when going from ‘colourblind scientist’ to ‘scientist who sees colour’, she does learn the propositional fact that she isn’t colourblind.
So, if she sees no colour, she ought to believe that the outcome of the coin toss is Tails. If she does see colour, both SSA and SIA say P(Heads)=1/2.
Yeah great point, thanks. We tried but couldn’t really get a set-up where she just learns a phenomenal fact. If you have a way of having the only difference in the ‘Tails, Tuesday’ case be that Mary learns a phenomenal fact, we will edit it in!
