Some guy from the WSJ does not like that PhD Jill Biden is called Dr Biden

8. Well, this is a stupid argument

As pointed out, her doctorate isn’t honorary, and none of the honorees mentioned are called doctors anyway.

On the other hand, it’s pretty rare in the academic world for professors to be called doctor these days. At some Ivy League schools the proper form of address is Mr. or Ms. More generally, it’s Professor. To my spouse, who has a Ph.D and is a full professor, his students address him by his first name. Except the students from Asia, who don’t feel comfortable doing that and use “Professor X.”

Honestly, it’s a regional and personal choice as to what you call yourself. And really, who cares.
