WeakenDiff: Easy

Logic Breakdown

Passage Summary: A reader thinks the local paper hates theater because they print way more movie reviews than play reviews.

Conclusion: The newspaper's arts section is unfairly biased in favor of movies over local theater productions.

Reasoning: The sheer volume of movie reviews published in the last year was more than five times the number of reviews for live plays.

Analysis: The author assumes that a difference in quantity automatically equals 'bias,' but this ignores the baseline frequency of these events. If there are 100 movies released for every 1 play produced, then 5 movie reviews for every 1 play review would actually show a bias toward theater. Look for an answer that suggests the ratio of reviews simply reflects the ratio of available shows or public interest.

If many more movies were released than local plays, then publishing many more movie reviews is expected and does not indicate bias. This directly undermines the letter writer’s inference from raw counts to bias.
