We investigated how two credibility cues \u2014 a doctor\u2019s expertise (years of work experience) and aggregate patient ratings (star ratings) \u2014 modulate brain responses to veracity cues (\u2018True\u2019 vs. \u2018False\u2019) presented after health- related headlines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We recorded EEG from 36 participants while they evaluated true and false headlines across various medical topics (e.g., vitamins, GMOs, vaccination).

Critically, \u2018False\u2019 cues elicited a significantly stronger FRN(RewP)-like response when delivered by highly rated doctors compared to less rated ones; no such modulation was observed for \u2018True\u2019 cues.
