First Lady Jill Biden asked to be called “Doctor” after her husband was elected president. She’s not actually a doctor. She’s also not nearly as smart as one and so she thought the title made her look like she was, at least to stupid people who don’t know better.
The justification for “Doctor” Jill’s request to be called a doctor was she has an EdD. That’s a doctoral degree in education. It’s a little like a PhD but much easier to obtain. No EdD in the entire universe could pass an introductory college chemistry or physics course.
I suppose I could ask to be called a “doctor” too, since my law degree is a J.D., a Juris Doctor, but my friends would laugh at that request, and rightly so.
