The study, conducted by the school’s Signal Analysis and Interpretation Lab, used artificial intelligence and machine learning to do a linguistic analysis of nearly 1,000 popular film scripts, mostly from the last several decades. Of the 7,000 characters studied, nearly 4,900 were men and just over 2,000 were women. And perhaps unsurprisingly, the male characters spoke far more than the female ones did, with 37,000 dialogues involving men and just 15,000 involving women…

They found that the language used by female characters tended to be more positive, emotional and related to family values, while the language used by male characters was more closely linked to achievement. African-American characters were more likely to use swear words, and Latino characters were more apt to use words related to sexuality. Older characters, meanwhile, were more likely to discuss religion.
