The Gender Equality Checkpoint

[it]

An experiment for guys:

Go with another guy to a largely female or at least a mixed gendered social environment. Initially make sure you integrate into the conversation with them and that you two are generally welcomed.
Then when there's a pause, and quickly "check your messages" while starting a stopwatch app on your phone and then putting it back in your pocket. Ask the guy about a recent date he had and how it went.
Don't ask him about her looks. As he goes, ask for additional details about her behavior, her actions, and what she does in life, and continuously judging her about those with the assumption that your friend is looking for a long term partner, pick them apart and extrapolate out loud - what they means about her, about how well/badly she'd treat him, how happy she'd make him, and even what it would mean for your future household or what kind of a parent she'd be.
When the last women leaves the table in discomfort or disgust, stop the timer, and check the results. For a control - do the exact while focusing instead more on how she looks, how far she went and generally stay in line with basic dude questioning.


p.s.
IME the experiment takes 3-17 minutes. As far as the control, your battery will most likely die before you get to stop the stopwatch. A good few of them will feel quite comfortable joining in.
