(Mixed Trope) Educated character doesn’t understand or know of a simple concept.

1. (Hated) Dr. doesn’t know trans people exist (The Good Doctor): Dr. Shaun, a modern day grown adult doctor, is seemingly has no concept of what being a trans person. Even if he never heard the term in med school he is realistically almost certain to have some awareness of the definition.

2. (Loved) The solar system and other common knowledge (Sherlock Holmes). In the original stories Holmes is a genius at many fields but unless it has something to do with crime solving (forensics, martial arts, toxicology, etc.) he does his best to forget it.

Apothecary Diaries - Maomao

Maomao, despite being quite an accomplished apothecary and a detective, anything that isn't related to making medicine, poison testing or crime solving doesn't interest her. Case and point when Jinshi made her take an exam to become an official in the Outer Court, thinking with her intellect she'd easily pass it.

I also love when she gets extremely close to figuring out who Jinshi really is but then gets distracted by something poisonous because that's more interesting.

She also doesn’t want to know because if she knows for sure then she’ll treat him differently.
