Letter to the Editor: The arts section of this paper shows a lamentable bias toward movies and against local theatrical productions.
Conclusion (lamentable = opinion)
The arts section of this paper shows a lamentable bias toward movies and against local theatrical productions.
Evidence
Over the last year alone, the paper has published over five times as many movie reviews as reviews of live plays.
Evaluate
The evidence involves a Curious Comparison, and the conclusion is offering an explanation for that asymmetry, so we can use our Explain Curious Fact mindset.
Curious Fact … How come the paper publishes five times as many movie reviews as reviews of live plays?
Author’s Explanation … The people who run the arts section are biased towards movies. They prefer movies over plays, so they choose to publish more movie reviews because they would rather write about and publish stuff that they like.
We always ask ourselves
1. Could there be an Alternate Explanation for the curious fact?
2. How plausible is the Author’s Explanation?
Goal
We can either hurt the argument by suggesting an Alternate Explanation for why there are five times as many reviews of movies as of live plays (maybe there are way more movies than plays / maybe the readers of the newspaper are five times more interested in movies than in plays), or hurt it by making it seem less plausible that the editors of the arts section prefer movies to plays and thus publish far more reviews of movies than of plays.
