> Observers may learn that in general, members of a specific cohort are substantially likely to be a specific type of person. For example, a particular cohort may over-represent users who are young, female, and Black; another cohort, middle-aged Republican voters; a third, LGBTQ+ youth. This means every site you visit will have a good idea about what kind of person you are on first contact, without having to do the work of tracking you across the web.
