> Because it's unthinkable that movies with male main characters could actually just be better than movies with female main characters Or, more realistically, it's not unthinkable that movies with a male lead could be better reviewed than movies with female main characters, especially when you open the field up to non-professional reviewers. We've see how ape-shit people went at movies like the recent Ghostbusters remake or even the new Star Wars series just because they put women in the kinds of roles that had traditionally been played by men. It's an interesting question of when machine learning models that reflect actual human biases are correct and when we should try to adjust them for that human bias. In the case of movie reviews, you could make the case that you'd want the models to reflect the biases of the reviewers. Just because a reviewer is being sexist doesn't mean it's wrong for the machine learning model to correctly classify the reviewer's sentiments.
