Rational Expectations is an approach to probability and expectations that was initiated by Muth in 1961. Muth's concept is based on an immense muddle and confusion in his mind about subjective and objective concepts of probability that confuses subjective probability with objective probability....

J. Muth's 1961 article on rational expectations was written without any knowledge on Muth's part about what a subjective theory of probability entails and is based on, or what an objective theory of probability entails and is based on. Muth's disbelief, that the individual, subjective...

The theory of rational expectations has no foundation in any extant theory of probability. None of the five existing theories of probability (Logical, Subjective, Classical, Propensity, and Limiting (relative) Frequency) lend any support at all to the Muthian conjecture that the subjective...

All Rational Expectation Theorists rely on the Fallacy of Conditional Apriorism (Long Runism)in order to operationalize the Objective Limiting Frequency Interpretation of Probability. However, such a limit only occurs in the far distant long run as the number of observations from Time Series...

No model can ever be true. By definition, models are only, at best, approximations to reality. Some models are better approximations than others, so one can talk about one model being better than another model. However, to talk about a model yielding true predictions means that the speaker does...

A very, very, very severe problem has been occurring repeatedly over the last 100 years in the social sciences and philosophy, when it comes to the question of understanding the meaning of Keynes ‘s logical theory of probability and his concept of rational degrees of belief. It is the failure...
