Episode notes
Decision Making in the Multiverse
- In the multiverse, many versions of you exist, but your decisions are driven by knowledge, not randomness.
- Most versions act like you do because human thought corrects errors systematically, not by chance.
Subjective Probability in Multiverse
- Probability in the multiverse is about the measure of universes where events occur, not randomness.
- All physical possibilities happen, but their proportion determines their relevance to decision-making.
Everett's Differentiation Explained
- The Everett interpretation uses differentiation of existing infinite universes, not splitting to new universes.
- Measurement outcomes cause a bubble of differentiation that spreads at light speed but remains finite.
