Abstract: The usefulness of non-Markov reduced equations of motion (REM) for the description of the time evolution of macrovariables is examined. We show that in general one should be very cautious when using such equations since the results may strongly depend on the addition of more variables into the REM. This is in contrast to the use of non-Markov REM in the calculation of equilibrium correlation functions which is always justified.
