## Abstract

This paper further studies Blass and Gurevich's iteration schemes of randomizing algorithms for randomized reductions [BG91]. An iteration scheme of a randomizing algorithm is honest if it passes a bit to a process independently of its value. We show that if a fair iteration scheme is honest, then it is independent. This implies the previous known sufficient condition for independence in [BG91]. On the other hand, we show that for independence, honesty is not necessary.
