You seem to be moving the goalposts a lot. First you discussed sampling error and different observers, until I pointed out that these are the province of ordinary stats.

Now you are discussing whether social experiments in an alternate universe might come out different. Of course they might.

I don't claim to be doing feminist philosophy - given how rapidly the definition shifts, how could I possibly know if I am? I certainly do feminist philosophy as per your first definition (worrying about biased samples and observers), and I certainly don't do it as per your second (thinking about alternate universes).
