I use the RSSA as the basis for calculating what I call the relative probability, in this group the first person probability, or, equivalently, the probability conditional on the life of the observer. The ASSA is by extension, the assumption for calculating the 3rd person probability. Let us perform a thought experiment. Imagine that you are the scientist in the Schroedinger cat experiment. Please calculate the probability that the cat stays alive. Let's call this the 3rd person probability. Assume that the vial of cyanide has an 50% (objective) probability of breaking during the experiment. Now imagine that you are the cat. (A very intelligent cat with a knowledge of probabilities) Please calculate the probability of staying alive. Call this the first person probability. Now imagine testing your calculations with experiment. First, pretend you are the scientist and perform a large number of cat experiments. Does your third person calculation statistically agrees with the experimental data? (i.e. you should see about 50% of the cats meet their demise) Now, pretend you are the cat, and perform a large number of experiments. Does the first person calculation statistically agrees with the experimental data that you have accumulated? (you should see your survival 100% of the time) The relative probability concept (1st and 3rd persons) can be used in other ways. Here is another example: You take a flight from New York to Los Angeles. Assume the following: The objective (3rd person) probability of a crash is 0.001 The objective (3rd person) probability of a hijacking to Cuba is 0.001. What are the first and third person probabilities of reaching Havana and Los Angeles? Answer: The third person probabilities are: Probability of a crash = 0.001 Probability of going to Havana = 0.001 Probability of going to LA = (1- 0.001) x (1-0.001) = 0.998001% The first person probabilites are Probability of a crash = 0.000 Probability of going to Havana = 0.001 Probability of going to LA = (1 - 0.000 ) x (1 - 0.001) = 0.999 This is just to illustrate the point that depending on the frame of reference of the observer, the experimental results will be different.
