BBC gets caught in yet another lie:

Okay, let's see it.

"Black women most likely to die in medieval London plague."

You had to edit the title. The full title is "Black women most likely to die in medieval plague, Museum of London says".

Which is obviously not a lie.

Community notes cite phrenology as definitive source.

You're confusing phrenology with forensic anthropology.

Phrenology claims the skull shape can determine personality traits. This has been shown to be false.

Forensic anthropology has a many datasets of the ratios of bone measurements so that race can be estimated. It's not 100%, but the museum looked at differences between plague and non-plague burials, both of which would be affected by the incorrect attribution of race, so a statistically significant difference between them cannot be attributed to that.
