A social media company is designing a new algorithm to curate content for its users. One team proposes an algorithm that prioritizes content based on what users have previously engaged with, reinforcing their existing viewpoints and preferences. A critic argues that this approach risks creating 'echo chambers' and limiting users' exposure to diverse perspectives. This criticism is primarily concerned with the algorithm's potential to exacerbate which cognitive phenomenon?
- AFundamental Attribution Error
- BConfirmation Bias
- CDunning-Kruger Effect
- DBystander Effect
Show answer & explanationAnswer & explanation
Correct answer: B. Confirmation Bias
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. An algorithm that prioritizes content similar to past engagement would feed into this bias, creating an 'echo chamber' where users are primarily exposed to information that reinforces what they already believe.
Why the other options are wrong
- A. The fundamental attribution error is the tendency to overemphasize dispositional explanations for others' behavior. (Incorrect)
- C. The Dunning-Kruger effect describes a cognitive bias where people with low ability at a task overestimate their own ability. (Incorrect)
- D. The bystander effect refers to individuals being less likely to offer help when others are present. (Incorrect)
Confirmation Bias
The tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values.
- Leads to selective attention and interpretation.
- Can strengthen existing beliefs and resist contradictory evidence.
- Exacerbated by 'echo chambers' and filter bubbles.
Memory trick: Our minds love confirming what they already 'know'.
