Do they not control for "trust" that the person has genuine factual knowledge? So your personal doubting due to lack of sources is controlled for, I believe, in their "manipulation checks" on page 1. So people who aren't presented with enough cues to create trust (and even the strongest rationalist has their own thresholds here, e.g. your heart surgeon, a Nobel laureate, etc) would be factored into account. Citation only matters to the listener when trust doesn't exist, esp when "determinations of truthfulness in the universe" isn't even what the researchers care to study -- but rather, how respect develops between the people who receive trusted facts vs trusted experiences :)
