I wish they had tested all 8 scenarios: Male/female participant, male/female body, catcalled/not catcalled.
Because even as a man I don't feel comfortable being alone at a subway station at night. Nor can I imagine would I then enjoy being catcalled.
I wonder how much your VR body seen in a mirror affects this. My gut says not a lot but more data would've been great.
Now, if your own VR body does affect your reaction there must be bodies which maximize/minimize reactions. That'd be fun to test. You don't even have to limit yourself to human bodies, what if you're, say, a dinosaur (with body height still being the same)?
