A study that relies only on self-reported claims of 'being in love' might be interesting to read, but such a study would be of higher quality if there was an objective way to take a group of people and sort them into one of two groups: "in love" or "not in love." Based on my own experience and experiences reported by others, I wouldn't reject the notion that such a sorting is possible in principle, although it may be beyond our current technological capability. The pain associated with being suddenly separated from someone that you have 'fallen in love with' can rival physical pain in intensity. What type of instrumentation would we need to detect when a person is primed for such a response? I have no idea.

No, not automatically. An objective measurement can be both worse and be better than a self-reported measurement. There no reason to believe that one is inherently better.

New material added to this thread uses the phrase being in a relationship rather than being in love. I found the latter phrase problematic because it involves a poorly defined mental state that has changed meaning over time. The former phrase is objectively verifiable by external observers.

I have read a book or two on the Design of Experiments over the years purely for intellectual curiosity; I've never actually defined and run a scientific experiment. So I don't have anything worthwhile to say on the general topic of the relative value of objective vs. subjective measurements in scientific studies.
