Interesting report to glance through but the problem I find with self-reporting studies is that, even if the responses are anonymous, people give socially acceptable answers to things that are governed primarily by feelings and unconscious actions. Such studies are fine for measuring conscious decision making such as why people quit a dating app but not for unconscious decisions where we know the reality is brutal but instead people prefer state a socially acceptable answer to not be outcast, criticised or spare feelings.

We know from a study on relationship predicting attributes which first asked women what they want in a man that personality was by far the highest trait selected for followed by earning power and attractiveness. The researchers followed up that data by observing their body language and what actually happened when they were dating. The results were very different. Attractiveness was now the dominant trait with personality trailing in second place in front of earning power. Observational studies show body language, vocal inflections and actual outcomes. Self-reporting studies show what people think but it does not always correlate to reality.

The old adage applies - don't listen to what they say, watch what they do.
