I find experiments like this fascinating, and the only way to combat what I call a paradigm prison. Let me give you an example...My accent drifts between northern euro english, and midwest american drawl. I get different service in scottish pubs or french bistros or american diners based on which I use (classic code switching). The most profound change though was when I wore a handlebar moustache. People smiled at me more, gave me compliments, struck up conversations at bus stops. Sometimes other men avoided me or scowled, but mostly, life became more positive. The fact that I could wax it up or leave it down, meant I could experiment daily, even hourly, in the differences in treatment. Throw in differences in accents, and it was fascinating. Have a different accent with moustache down, and you get 'othered', have a different accent and mustache up 'you must have a few stories to tell'. It made me wonder how much of masculinity is pushed onto us as opposed to chosen by us. After all, you get grumpy when every stranger scowls at you, and cheerful when strangers give you compliments. Now, what other experiments can we find?
