The Influence of Source Credibility on Communication Effectiveness.
Hovland, Carl I., and Walter Weiss. "The Influence of Source Credibility on Communication Effectiveness." Public Opinion Quarterly 15, no. 4 (1951): 635-650.
Why this matters here
Hovland and Weiss experimentally studied the effects of source credibility on persuasion. The chapter uses that evidence when discussing trusted messengers without equating credibility cues with the truth of a claim.
