Whom to trust? Inferred source credibility and response borrowing in a memory task

Area of Science:

• Cognitive Psychology
• Information Science
• Human-Computer Interaction

Background:

• Understanding how individuals evaluate information sources is crucial in the digital age.
• Assessing source credibility influences decision-making and information seeking behavior.
• Previous research highlights the challenges in distinguishing reliable from unreliable information.

Purpose of the Study:

• To investigate if individuals can discern credible information sources from random ones based on provided responses.
• To examine whether source credibility inferences regulate information borrowing behavior.
• To identify conditions under which differentiated response borrowing occurs.

Main Methods:

• Three experiments involved participants judging trivia statement validity with responses from credible or random sources.
• Experiment 1 assessed source credibility using easy questions before evaluating difficult ones.
• Experiments 2 and 3 tested response borrowing on difficult questions after studying correct answers, with varying delays (immediate vs. 24-hour).

Main Results:

• Participants frequently identified the credible source explicitly across all experiments.
• Differentiated response borrowing, favoring the credible source, was observed only in Experiment 2 (no delay).
• Explicit credibility identification did not consistently translate to regulated response borrowing.

Conclusions:

• Individuals can often explicitly infer source credibility from provided responses.
• Regulating response borrowing based on credibility is less common and context-dependent.
• Favorable circumstances, such as immediate recall, are necessary for effective use of credibility judgments in information borrowing.
