Science isn't the only form of empiricism. In this case, the writer is reporting what she has learned through a long process of observation, a useful form of experience. No doubt in the process she has formed ideas, watched to see if they bear out, changed her mind, examined events in context and their outcomes, come up with generalizations based on observations over time, and so on. You know, how most people learn most things.
Could she be wrong, sure, but as we have learned over the past few years, so can more "scientific" approaches to psychology and sociology. But that doesn't really matter because what she's doing isn't failed science, but taking part in a sort of humanistic shared inquiry. It's a woman reporting her observations and thoughts, not as claimed facts, but as suggestions readers can integrate into their own developing understanding, so they can build on them to make their own observations and inferences.
