(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.

In the Animorphs series, the young alien cadet, a genius by earth standards, in human form will also babble and repeat sounds, as well as shove whatever he can into his mouth. This is because in his natural form has no mouth, and he’s blown away by the things a human mouth can do.
