The language of the post says something that cannot be (meaningfully) derived without a control group of people that didn't experience a counterpoint: "... the situation of being a young woman alone at night in a subway station being enough to generate the sense of fear."

As I understand it, everyone in the study experienced all of that in combination, so any subset of those things may have been enough to generate a sense of fear: being alone, being at night, being a young woman, or being on a subway station.

The common objection I see is that everyone feels fear alone on a subway station at night, so the statement is misleading. That matches my personal experience, so I also see that statement as misleading, regardless of any work done by the study.
