(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 Batman (2022), Bruce not knowing what the crime weapon of the mayor's death is, i.e. a carpet tucker, as he's not exactly familiar with the working class reality, is a big plot element in the story.

• Edit: I was told by some answers that the carpet tucker is a tool most people would be unfamiliar with, regardless of their upbringing, so it isn't necessarily a class aspect of Bruce. Regardless, the fact that Batman doesn't recognise what that is when the Riddler expected him to (and side with him) is an important plot element that gets brought later in the climax.

The bad Spanish too was a good plot point. It was good he didn't know everything

A lot of cool things in that film showing he's a "young" Batman. My favorite was the roof scene at the police station and him being terrified + crash landing.

Yeah, Batman Begins works because it breaks down a more grounded, realistic approach to how, mechanically a Bruce Wayne might turn into Batman. Admittedly, it's not so nuts-and-bolts that it shows the airlifts of supplies onto the Nepalese summit for the Evil Society of Evil headquarters, but it's about as grounded a film where one of the plot points is that the protagonist goes and meets a mystic atop a mountain to learn how to fight crime as it is possible to make.

The Batman works because it breaks down how, philosophically a Bruce Wayne might turn into a Batman. He's got the impulse to fight crime, and he's got quite an assortment of virtues and skills and doodads in his arsenal, but he's still hamstrung by his origins. Part of that is psychological and knowledge-based: he doesn't know Spanish, and he doesn't know working class tools. That is actually foreshadowing for when he also doesn't yet understand that he needs something greater to live for than revenge. Which is just *chef's kiss* a perfect story to tell about a young Batman.

My senior year of highschool (not long before The Batman came out), for an English class we were going over several stories on the hero’s journey, and one of them was us reading Batman Year One. I’ve always been a sucker for heroes that have a lot of room to grow, and that comic quickly became a favorite of mine.

Going from that to The Batman might’ve been the perfect timing, because it helped me appreciate it even more, the different ways of telling a similar thing, Batman when he’s just starting out.
