I think you're forgetting the term "tend". Even in Iran my expectation is that if you were to repeat the experiment from the featured article you would get similar results. I assume though that Iran has a smaller portion of the population in college and that men are preferentially pursuing political or theological power over STEM education. Of course, these are assumptions which is why I'm asking questions to understand better. Do you think that in Iran their children's books more prominently feature female scientists?
