The 6th element (not the sequel to the Luc Besson movie, unfortunately)

You ruined my hopes :(

This might involve dressing an infant in neutral clothing (what they aptly and funnily called "neutrally clothed infant stimuli"), then getting a non-parent adult into the room with the infant, stating the infant's sex differently with each adult, and seeing how the adults interact with the child

This makes me thinking about our society that enforces us making stereotypes. Just enter a toy or clothes (here is the link with the above snippet) shop. The difference between boys and girls (where it should in principle not matter) hits us straight into the face. As a result, even if one doesn't want to make any stereotype, one makes them.

And then I read the rest of the post and found out we finally kind of agree :)
