Answer to Question 1

Adaptive expectations are based on the past. An adaptive expectation is irrational only if there is reason to believe that it is possible to formulate a better guess. Though one can never be sure that the trends of the past will continue unaltered into the future, it may not be possible  without undue expense  to acquire enough information and understanding to justify the conclusion that the known trend will fail to persist. If the known trend has been reliable, there is no obvious reason to doubt its persistence, and there is no inexpensive way to conduct a forward-looking assessment, the adaptive expectation is rational.
