The study does, according to The Post, concede that “the number of women mentioned was proportional to the number of tenured women in the academic biology workforce over time,” but Brookshire later seemingly dismisses this fact as irrelevant, given that the study finds references in textbooks do not “reflect the gender and racial diversity of who’s in the classroom.”

Here's a hint: no two classrooms are the same. A classroom in New York City, Nebraska, and near the Mexican border are all going to be different. Unless you're going to have different textbooks for different racial makeups, making the textbook reflect racial makeup of the classroom is a fool's errand.
