This is really sounding like the great mystery of our time! Perhaps we should design an experiment. I'm willing to use some of the names in my ward as subjects.
It seems to me a good place to start the experiment is in the names that are being displayed correctly. If we change some of the names, it should propagate to the beta directory within 48 hours. If the changes propagate, then that would give us a clue as to what fields are tied to the names in the directory.
So, since all my names seem to be appearing correctly, I will do the following tomorrow evening:
- change three [Preferred_First_Name] to match the values in [Legal_First_Name]
- change three [Preferred_First_Name] that do not now reflect the person's actual preferred name to correctly display their preferred first name.
If these propagate to the directory in 48 hours, it will at least tell us that these are the relevant fields.
What other experimental units should we test?
(I know...I get overly excited about research. I'm a nerd, what can I say?)
