Why would a single blind study be less effective in controlling for experimenter-participant communication than a double blind study?
What will be an ideal response?
In the typical single blind study, the researcher can still communicate expectations to the participant in very subtle ways, without knowing about it. If the experimenter doesn't know which group the participant is in, though, it will be impossible to communicate critical information that will affect the participant's behavior.
