“Men genuinely believe that they know what women want, and are earnest in their attempts to explain ‘what women want’ to women. They are deeply confused, because of course they know what women want! Right?”
This is why it’s important to include women in the process when writing ads/movies/etc. How are you supposed to know what women want if you don’t actually ask a woman? How are you supposed to write a female character realistically if you don’t get a woman’s perspective (or even better, have a female writer!)
On a broader note, this is why it’s important to have diversity on the screen AND behind the scenes (looking at you, Matt Damon). Maybe your team can’t represent every single aspect of a character, whether it’s race, gender, sexuality, class, or something else – but it’s really hard to write a diverse world (aka the real world) if you don’t include more than just white, heterosexual men on your team.
