It's been suggested in a fairly upvoted answer to a related question that the complexity of the electoral/voting process is a main driver in beliefs in voting fraud, at least in developed countries.
Are there cross-country empirical studies on the association between the complexity of the electoral process (either operationalized objectively or merely as perceived by voters) and beliefs that fraud is occurring?
(10 up-votes, which is what that answer got insofar, might not be enough to support a q on Skeptics notability-wise, so I'm asking here.)
Somewhat related, I found a paper that does find a moderate association in Australia between belief in fraud happening and the perception that rules are too complex, but by rules there they don't mean the counting process in itself, but mainly the "complexity of the preferential system" used in Australia, although the latter does have some implications for the complexity of the counting process. Two thirds of those surveyed would have also preferred that the PM be directly elected; there was a stronger correlation between the desire for this particular rules change and the stated belief that fraud was happening.
