So are we saying that any advert must show a male and female at the same time? Are we going to deny those moments in the real world (a single parent, a parent looking after the Made In Germany A Long Long Time Ago Shirt whilst the other one is out etc) and say they can never be shown on tv again? I hope you understand exactly what “without outside influence,” means in what is little more than an observational study. Also, if you’re going to use evidence from a field, why not include any of the recent salient literature. It’s nice to have hard access to datasets.
