Back when I wrote my article on the Sleeping Beauty problem for 1000-Word Philosophy, I had to cut a chunk of the article that dealt with Dutch Book arguments against thirders because I was running up against that hard 1,000-word limit. Unlike most scraps of my writing I have had to cut from a longer work, I was able to rework that chunk into a full article on Dutch book arguments which is now available on the 1000-Word Philosophy website. Thanks so much to Nathan Nobis and the other editors at 1000-Word Philosophy for their help and patience with this entry – it’s not easy work making technical topics accessible to a general audience!
