Emily Adlam discusses the problems facing several interpretations of quantum mechanics: principal among them, the probability problem. Prepare for discussion of self-locating credences, branch-counting, and whether a mechanism deposits consciousness throughout the branching wavefunction of the universe.Video of this interview is available on YouTube.To support the channel, do please oh please consider donating, either via PayPal or Buy Me a Coffee.Follow me on X because you’re awesome.EPISODE CHAPTERS:00:00:00 Introduction00:01:52 The problem of recovering empirical confirmation00:04:47 The many-worlds interpretation00:07:01 The measurement problem00:08:42 The probability problem in many-worlds00:12:06 The decision-theoretic approach to probability00:16:33 Self-locating evidence and Everettian quantum mechanics00:19:20 Pure vs. superficial self-locating credence00:25:08 Can the Born rule constrain self-locating credence?00:30:15 Interpretations vs. theories of quantum mechanics00:34:51 Can we save science from quantum mechanics?00:44:30 What happened to the Copenhagen interpretation?00:46:45 What do physicists believe about quantum mechanics?00:48:27 The anthropic argument for God00:56:22 Multiverses, fine-tuning, and self-locating evidence Get full access to Miles K.

Tim Mawson, professor of philosophy at Oxford, discusses the contours of the newly emerging philosophical investigation into the meaning of life. What does it mean to say that life's meaning is subjective versus objective? Would life be meaningful if we were immortal?
