Can a Sim be "taught" how to behave?

[TinySpaceFox]

A handful of sims in my town will autonomously insult other sims when conversing with them, despite not having the Evil, Mean-Spirited, or Inappropriate traits. If I were to take control of them and select only friendly options for socialisation, would they move away from being rude?

Hi Tiny Space Fox, it sounds like some of your townies are in the nerd social group. If they are a nerd, one of the interactions is "insult intelligence." Unfortunately, it comes up very often. For my playable sims, I'm constantly having to x that out if they get in that group. Unfortunately, I don't know how to stop it in townies.
