:::::::Falk understands probability in the subjectivist way. Rick understands it in the frequentist way. Different notions of probability make different assumptions reasonable or unreasonable, motivate different approaches to MHP. For Falk, probability is in her mind, her information. For Rick it is in the real world. Both ways of using probability are reasonable. Since they are different kinds of probability, assumptions concerning them have different meaning, and conclusions drawn with them have different meaning. The answer may be "switch", "2/3" but the meaning of "2/3" is completely different.
