This can help us understand the typical properties of worlds within such states, and hence explain the empirical success of quantum theory within a many-worlds framework. We give three reasonable axioms which lead to the Born rule in the case of quantum theory, and also yield natural results in other cases, including a many-worlds variant of classical stochastic dynamics.<\/jats:p>","DOI":"10.22331\/q-2023-04-06-971","type":"journal-article","created":{"date-parts":[[2023,4,6]],"date-time":"2023-04-06T12:23:37Z","timestamp":1680783817000},"page":"971","update-policy":"https:\/\/doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Probability in many-worlds theories"],"prefix":"10.22331","volume":"7","author":[{"given":"Anthony J.","family":"Short","sequence":"first","affiliation":[{"name":"H.H.
