This’d be very unethical to do IRL, but I’d like to do an experiment where you raise someone without exposing them to ANY established fictional media and seeing what, if any, kind of story or fiction they can tell
There could be a grander scale experiment involving the kids who did this experiment who’ve grown up and become parents. Essentially creating an new line of culture untouched by the wider world. It’d be mad interesting to see what it’d be like
